Memory leak in video ...

Hello,
I read the article about the garbage collector in Flash AS3.0
Now i have a flv movie that loops. When i run this, it will
increase a little bit in memory after a few hours.
But now a store has a computer with this video and it's
running for a few weeks now. And it crashes
because the flash memory was extreem high.
It's normal to visit a webpage and leave within one hour..
but what if you want to use flash for non stop hours?
Why, for example if the memory get's extreme high, doesn't
the garbage collector take care of it ? Or is this not possible.
I used these line of codes for to play a video in a loop.
When i was testing some files i noticed that when you use the
trace command a lot it will also
increase the memory of the current flash. Isn't that weird?

Hi, could you provide the following information for investigation?
1. AIR version
2. OS version
2. Simplified version of your app (with source code) that can still reproduce your issue
Thanks,
Jian

Memory leak in video player

Hi
We have built an Adobe AIR application, where I've defined a video player in the mxml part. Now in the actionscript I'm looping over a playlist in XML where I'm updating the source of the video player everytime the playlist starts the loop.
Now what's happening is that my AIR application is occupying more and more memory with time, and after some time when it takes up lot of memory, my app crashes. How do I flush out previously loaded video from memory, so when the next video starts previous video should be flushed out from memory, how do I do that?
Thanks in advance
Regards
Pankaj

Memory Leak with Flash Game - video of incident - Fix?

My hypothesis:
There is a memory leak in Flash Player that leads to Flash crashing, predictably and repeatedly, when used.
My question:
When will this problem be fixed?
Evidence:
Observe the progression in the following single-take video of me playing my favorite Flash game, posted to Youtube. Skip to the times indicated in the "About" description for the video to observe the increase in use of physical memory, as observed in Windows Task Manager, until there isn't anything left.
http://www.youtube.com/watch?v=gNIJvTuUitU
My computer gets bogged down, the game stalls out, and Flash needs to be closed to enable my computer to function once more. It makes it impossible to play this specific game for very long, and is an insidious problem lurking in the background every time I watch a video, play a game, or use Flash Player for any purpose. My computer always slows down, with the problem worsening as time passes until I need to close everything and start again.
Details:
Flash Player Version: 11.7.700.224
Operating System: Windows Vista (32-bit)
Browser: Mozilla Firefox
(Also happens when using Google Chrome)
Conclusion:
If you need further information about my specific computer, please feel free to ask.
If this problem is specific to my computer, I would appreciate knowing this and determining a way to solve the problem. My suspicion is that the problem originates in Flash Player itself and is experienced by many people in a variety of circumstances. It is my hope that an articulate response indicating how long it will take to correct this bug in Flash Player can be provided.
Thanks in advance for your help.

Memory leak problems with loading videos over and over.

I'm having memory leak problems with loading videos into a VideoPlayer aswell as FLVPlayback.
What the flash should do:
- Should be running for 7 days without having to restart the projector.
- Interface that shows people around a 360 3D model with 5 different parts and at the stops it makes during the rotation you can click to zoom in on a location which plays a movie for that aswell.
- Shows a video out of 5 parts for a 360 rotation in 3D in mp4 video (added each time and cleaned up, see code below).
- Still images are used when the video clips are done playing (MovieClip in stage).
- Should run automatically when there is no user interaction for X minutes.
What the problem is:
- The flash (as a exe and swf i guess) starts to consume memory over time (say 10 hours) until the projector crashes. This usually at around 1.75 GB of memory.
I cannot see why the Flash cannot garbage collect this and free up the memory. Mabye there is something I don't understand about the garbage collection in flash?
Here is some code from the video loading and playing:
var fVideo:VideoPlayer;
VideoCreate();
function VideoReady(pEvent:VideoEvent):void
trace("VideoReady()");
     // start playing video
fVideo.play();
function VideoLoad(pUrl:String):void
     trace("VideoLoad(" + pUrl +
     VideoCreate();
     if (pUrl != "")
          if (fVideoFolder + pUrl == fVideo.source)
               fVideo.seek(0);
VideoReady(null);
          } else {
trace(fVideo.state);
               if (fVideo.state !=
VideoState.DISCONNECTED) fVideo.stop();
fVideo.close();
fVideo.load(fVideoFolder + pUrl);
     } else {
// error no url
function VideoCreate():void
     trace("VideoCreate()");
     // remove old one
     if (getChildAt(0) == fVideo)
          removeChildAt(0);
     fVideo = new
VideoPlayer(1024, 768);
     addChildAt(fVideo, 0);
     fVideo.autoRewind = false;
fVideo.addEventListener(VideoEvent.COMPLETE, VideoDonePlaying);
fVideo.addEventListener(VideoEvent.READY, VideoReady);

Hmm. It's in connection with Dropbox. Så apparantly you can only use one of the two at the same time if you want the programs integrated in Finder.

I've noticed this especially when I youtube or video stream for a while. Switching between tabs takes 3-4 seconds. Definitely a memory leak! Is it a general problem or addon specific?

Also, when I try to close firefox and restart it, the process doesn'y get killed with the normal Command + Q in Mac.
I need to use Force Quit instead.

Try updating Flash. You appear to be running an older version dating from September 2010 which might be the cause of the problem. Download from http://get.adobe.com/flashplayer/
If the problem persists after updating, try running Firefox in [[Safe Mode]]. If it functions properly in that configuration, then one of your add-ons is the culprit.

Full Motion Video - memory leak?

Good afternoon.
I am using captivate 1.01.1418.1418 to record and present
standalone demos of rich client web technologies. The default
capturing techniques just don't cut it, so I need to record the
entire demo in full motion video.
What I have noticed is that when you edit the video AND ALSO
when running the published demo using either stand-alone or swf
object methods that there is a huge memory leak. I am talking to
the magnitude of 20-25 meg / second while displaying full motion
video.
My latest presentation is 22 slides where 3 of them are short
full motion video clips recorded at 1024x768 with no audio. The
clips are between 30-90 seconds.
The generated output exe is 6 megs and if I generate it with
all compression off it is 11 megs. When I run it, my memory usage
goes to 1.7 GIG of Physical Memory and over 2 GIG of Virtual Memory
in use. The movie playback then turns solid red and my machine
hangs up until I can manage to kill the playback.
Is there a known issue with full motion video and memory
leaks? I can understand if it took more memory to run it, but using
3+ gig of RAM to play a 10 meg file? Something sounds off to me.
I had purchased this product to record and display full
motion demos and so far it has not been able to meet the needs it
promised to deliver.
Any help anyone provides is greatly appeciated.
Please respond here and/or email me at
[email protected]
Thanks in advance for your time.
-Ray
P.S. I remember seeing the same behavior on my trial version
of Captivate 2, however, my trial has expired and I cannot see if
the leak is of the same magnitude.

Hi Ray,
You are experiencing "normal behavior" for the use you are
putting Captivate to. It was never designed as a full motion video
capture tool. I won't argue whether or not the marketing people
ever said it was capable of doing what you say you bought it to do,
but I really doubt they would make a claim that everyone knows is
not true ... if you can find something official from Adobe
asserting that, I'd sure be interested in seeing it.
The full motion feature was intended to be used to
demonstrate 2-3 second drag-and-drop operations, or use of a
scroll bar action of about that duration. In addition, you stated
you are capturing at 1024x768 size, which is an image of truly
gigantic proportions - adding to the full motion load you are
already throwing at the product. Could it be that another product
is better suited for what you want to do? I'd consider that
seriously because you are asking more of Captivate than I believe
it can deliver on anything but a machine designed for 2015
processor speeds with infinite resources.
It is especially sad that you own and used Captivate 1.0.1,
then spent an additional 30 days using the Trial version of
Captivate 2.0 ... but are just now finding it doesn't do what you
thought it should do. Again, sorry for your trouble.

Cropping Crashes Aperture 3 due to Video Card Memory Leak?

Recently after updating from 3.1.1 to 3.1.2 I have been experiencing crashing issues whenever I perform the cropping action. I see the death of wheel following hitting the return key. There was one time when the master version itself vaporized into thin air. I also noticed from the iStat Menus that the issue only occurs when the ATI Radeon HD 2400 memory usage has reach its full capcity. I quite firefox to release some of the memory then Aperture functions normally until the memory runs out again. I would then see the death of wheel once again when I crop.
Is Aperture crashing because I need a more powerful video card or is it a memory leak issue with the application?
Thanks!

Lets see if we understand this correctly.
You had a system on which Aperture was crashing when you used the crop tool. You then got a brand new system and the crop tool still causes Aperture to crash. Am I correct so far?
What are the common factors between the old and new systems as far as Aperture goes? Not knowing how you migrated from the old to the new the only thing we can say for certain is that the library is identical.
So have you run the basic library first aid steps? Another thing to try is to create a new empty library, put an image into it and try cropping it and see what happens.
Let us know what happens after those steps,

I migrated everything from the old computer to the new. I also tried creating a new library and the issue persists. I've also tried the First Aid options all of 'Repair Permission, Repair Database, and Rebuild Database' none of which worked. I've also tried reinstalling Aperture and it crashes on the first crop.
I will need to be editing many photos in a few weeks and now I'm stuck with this issue.. HELP!!!!!!!
It seems like others have run into the same issue also but no solutions!!
Why is aperture 3.1 crashing after cropping images, any one else?

Memory Leaks   Unresponsive Mouse

2009 8 core Mac Pro w/ 24 GB of RAM, ATI Radeon 4870, and a SeriTek PCIe eSATA card (card only has drives connected when running a manual drive clone). When running Toast 10 or Parallels 9, my RAM will fill up (I use a program called Menu Meters to monitor stuff). This machine worked just fine under OS 10.9 and earlier - no issues like this at all. ClamXAV will also completely fill the RAM up (the meter will be full green, instead of part green, then mostly grey when Toast or Parallels fills it up). I have to use Terminal to purge it so that the machine is usable.
The other thing that happens is that sometimes when the computer wakes up or I am in the middle of doing something, the mouse will still move, but the dock will not pop open and the left button the mouse doesn't respond. The right button will open the right click menu, but will not respond normally at all. I have tried a different Magic Mouse, but the problem is the same.
I thought that it may be a problem with the factory RAM and the Kingston RAM not playing nicely together. So I ran it with just the factory 8 GB and then ran it with the Kingston 16 GB - the problem persists no matter which RAM is installed. All of the RAM also passes the memory tests in Rember and TechTool.
So, I need to find out if someone thinks that maybe the bluetooth module may be going bad causing the mouse issues. I also need to find out what is causing the memory leaks. I followed the steps that someone gave on this site to boot into safe mode, repair permissions, reset PRAM, then reset SMC (or the other way around - I did it like they said to). It did nothing to fix the problem.
I need some guidance here. As I stated early on, the machine worked perfectly with OS 10.9. I have WAY too much software that I use, so doing a completely fresh install is out of the question - I don't have time to reload everything. This problem is annoying and I know that I am not the only one having these issues. Any input will be greatly appreciated. Thanks in advance.

Here is the EtreCheck report:
Problem description:
Memory leaks when using Toast 10 or Parallels 9. Mouse also become unresponsive (it will move, but left button does not work and dock will not pop open - mouse problem happens independent of the RAM being filled up - different mouse was tried with same result).

Huge memory leaks after upgrading from kernel 2.6.38(?)

My system began leaking memory some months ago and I've little to no idea what is causing it. The closest hint I can give is that I think these problems started around upgrading from Linux 2.6.38 to 2.6.39 and have continued with 3.0 aswell. Sometimes my whole system freezes due to extensive swapping (HDD usage led stays lit), sometimes it stops after consuming almost all of my 4 GB RAM.
I think the leak has to come from inside the kernel because all sysmon apps claim no application is eating too much RAM yet the system memory consumption is at 100 % or even using swap. Even after I kill Xorg the memory usage will stay at least at 2.0 GB, when it should be less than half a gig.
I'd like to guess the blame is on Nouveau, because it was giving me a hell of a time back with Linux 2.6.39. It had a habit of freezing my system when re-enabling suspended compositing (both with Kwin and Mutter). Also video playback was corrupted sometimes. These probs have since been fixed with Linux 3.0.
I cannot name any spesific app that might trigger this memory leaking. I don't play any games and mainly use Firefox, Chromium and VLC day in, day out.
There seems to be absolutely no way of reclaiming the reserved memory than rebooting the whole system. I have even tried unloading Nouveau.
I am currently running the [testing] repo with ~daily upgrades.

OK, this kind of surprised me. No wonder I couldn't find any relevant stuff while googling for kernel issues. I have had Strigi disabled for some time now because it is miserably broken, but I now disabled the whole Nepomuk too. Let's see if my problem now goes away or what...
The release of KDE 4.7 Beta 1 actually lines up with the launch of Linux 2.6.39 so this really might be the case. I moved to KDE 4.7 already with the first beta.

Memory leak in Flash with Win7, IE9, 64bit

I have been having an issue for quite some time on 2 different computers. Both of them are Windows 7 64bit and use IE9.
Generally I have 1 - 5 tabs open in IE at any given time. Usually one of them is a tab for Yahoo Mail. Other tabs are related to whatever I may be searching for or doing at that time, so pretty varied. Throughout the day at random times I will begin to get a grey icon for anywhere on some tabs where there is supposed to be a flash video (like the ad in the right side of the Yahoo Mail tab)... When it happens I can open Task Manager in windows and I notice that 1 or two "iexplore.exe *32" processes have memory consumed in excess of 600,000K. When I end those processes I am again able to see any flash videos that need to be viewed.
If I leave Task Manager open throughout the day I can see the memory consumption increase on various tabs until I cannot see any more flash videos or even open new tabs in IE until I end those processes. Further, the memory does not get released if I just close the tabs in IE, but I must either end the specific process or close all tabs in IE so that IE is completely unloaded.
I have since uninstalled the Flash player and the issue has gone away. I can re-install the flash player and the issue returns. Can you please help? This has been a huge annoyance and I had hoped that it would be fixed sooner or later. Unfortunately it has not been fixed and has finally prompted me to post something....

First, I just wanted to follow up on this thread and let you guys know that we'll continue to look into it. I also want to clarify some player behavior, and provide tips for helping to identify a defect that we can take action on.
Whenever you refresh/reload a tab, the browser should signal to us that our process is being destroyed, at which point we would release all of our resources and shut down. SergeStone's comment above makes it sound like this might not be happening in a particular case. I'm going to build out a few tests this week to explore this in more detail, and I'll follow up with results.
Also, it's worth discussing the difference between memory consumption and memory leaks. Flash Player is designed to consume a percentage of your available memory. If you have a 32-bit machine with 2GB of RAM, we're going to consume a lot less memory than a 64-bit system with 16GB of RAM.
Not all Flash content is authored well. If the ActionScript developer is continuously loading objects into their SWF and never releasing them (a slide-show is a good simplistic example), you'll see a steady usage increase as each new object loads in. You should also see that evenutally, our automatic Garbage Collection process will kick in. Memory will peak out, and then you'll see a short CPU spike as we look at all of the available objects and cull as many unused ones as possible, consumed memory will dip down significantly (as long as we can cull stuff), and then start growing again until the next time GC kicks in. We tend to do this judiciously, as poorly-timed GC can cause games to stutter if it happens when lots of things are moving around on the display and you don't have a lot of available CPU.
If it's our bug, it should be straightforward to fix, and I can follow up to this thread with a beta build for you guys to evaluate once we have one available. In the meantime, it would be interesting to know if you're seeing the problem on our current Beta builds (which is where we would do the work).
Here's a link to the latest Beta download:
http://labs.adobe.com/downloads/flashplayer11-5.html
Also, the simplest example is the most actionable. If you can find a situation where a site in a single tab reproduces the problem, that's a quick and easy thing to deal with. If the repro case involves opening seven tabs and waiting six hours, someone needs to repeat that over and over, until they can isolate what content experiences the problem and then iterate a bunch more with a debugger attached to try and isolate the root cause. The more complicated the content, the more difficult that is.
Secondly, I wanted to offer some actionable suggestions that you could use now to work around this issue.
Try Firefox or Chrome. Both of these browsers run Flash Player as a separate process.
For those of you using Performance Monitor and other tools to measure, you can directly observe the resources used by Flash Player
For the folks concerned about Bookmarks synchronization, both Firefox and Chrome provide native bookmark syncing and import from IE mechanisms.
Xmarks is a really nice, free utility that provides cross-browser, cross-platform bookmark synchronization.
Thanks,

Memory Leak Issue With Win7 64 bit and Youtube.

I have a Win7 64 bit using IE9 with version 11.4.402.265 installed. 4 MB installed.
Whenever I go to Youtube or Liveleak, and watch videos, over time it uses up to 4gigs of my memory! Even if I close the window, it does not free up the memory until I Ctrl/Alt/Delete and shut down the window(s).
I normally only keep open 1-2 windows. Google toolbar is about the only thing installed. I can open 5 and more tabs, but as long as the site does not use flash, I don't have issues and each window usually uses under 200k memory watching them in task manager.
When I go to open and watch a youtube video, it slowly climbs to 200k and within an hour, I can be at 2 gigs or more memory and up to 4 gigs within 2 hours (or sometimes much sooner). Closing the window does not release the memory until I end task on it and then after a minute or so, the memory seems to clear and everything is back to normal.
I searched the forums and seems lots of users, report memory leaks, some using yahoo toolbar installed, which is not my case. I do use yahoo as my e-mail address, no idea if that is related or not. I had the same issue when I had the prior Flash version installed, this has been going on for months. Right now having only this window open, using 129, 192 memory. If I open one more window (using the 64 or 32 bit browser) and start youtube, the memory in that window keeps climbing about 50-100kb a second, so it adds up quickly. I have kaspersky running in the background and that is about it other then my nvida driver setup.
Really frustrating that so many people here and across the internet have reported this. I did have IE8 a few weeks ago and still had the same issue, upgraded to IE9 to see if that helped.
Interesting side note, if I pause a video, it slows way down on the memory leak, but still rises at a slower pace. I don't know if this is an IE thing or Flash. I have had this setup since 2009 and don't recall having issues with IE7. I use Youtube so much as a teaching instrument as a music teacher, so constantly have lessons going on it.
Thanks and hope someone has come up with something. I also build computers and have done some programming, so I could modify a file if needed with clear instructions.

This could be similar to bug https://bugbase.adobe.com/index.cfm?event=bug&id=3334814

How to fix huge iTunes memory leak in 64-bit Windows 7?

iTunes likes to allocate as much as 1.6GB of memory on my dual-quad XEON 8GB 64-Bit Windows computer and then becomes unresponsive.
This can happen several times a day and has been going on for as long as I can remember. No other software that I use does this - only Apple's iTunes. Each version I have installed of iTunes appears to have this same memory leak. Currently I am running version 10.7.0.21.
I love iTunes when it works. But having to constantly kill and relaunch the app throughout the day is bringing me down.
Searching for a fix for this on the internet just surfaces more and more complaints about this problem - but without a solution.
Having written shrinkwrapped software for end users as well as for large corporations and governments for more than 25 years I know a thing or two about software. A leak like this should take no more than a day or two to locate using modern software tools and double that to fix it. So why with each new version of iTunes does this problem persist? iTunes for Windows is the flagship software product Apple makes for non-Mac users - yet they continue to pass up each opportunity they have had over the years with each new release to fix this issue. Why is this?
Either the software engineers are not that good or they have been told NOT to spend time on this issue. I personally believe that the engineers at Apple are very good, and therefore am left thinking that the latter is more likely the case. Maybe this is to coax people to purchase a Mac so that they can finally run iTunes without these egregious memory leaks. I would like to offer another issue to consider.
Just as Amazon sold Kindles and Google sold Nexus tablets at low cost - not counting on margin for profit - but instead they wanted to saturate the marketplace with tools for making future purchases of content almost trivial to do with their devices. Apple also counts on this model with their pricer hardware - but they also have iTunes. Instead of trying to get people to switch to a MAC by continuing to avoid fixing this glaring issue in iTunes for Windows I would like to suggest that by allowing their engineers to address this issue that Apple will help keep Windows users from jumping ship to another music app. The profit to be made by keeping those Windows users happy and wedded to the iTunes store is obvious.
By continuing to keep this leak in iTunes for Windows all it does is lower my esteem for the company and start to make me wonder if the software is just as buggy on Macs.

I have same issue. Ongoing for more than 1 year and currently running iTunes 11.3.
My PC is Dell OptiPlex 990 I7 processor, 8GB ram, W7 64 [always keep things patched up to latest OS updates etc]
I use this iTunes install to stream music videos etc to multiple appleTVs, ipads, iphones etc .. via Home Sharing
Store all my media including music, videos and apps on separate NAS .. so the iTunes running on PC is only doing the traffic cop role and streaming / using files stored on NAS .. creates lots of IO across my network
Previous troubleshooting suggest possible contributing causes include
a) podcast updates .. until recently I had this auto updates on multiple podcast subscriptions, presumably the iTunes would flow this from the PC to save on the NAS across the network .. if the memory leak is in the iTunes network communication layer (?bonjour?) this may be sensitive to IO that would not normally occur if the iTunes file saving was local on the same PC
b) app updates .. have 200+ apps in my library and there is always a batch of updates .. some updates 100s of MB is size .. routinely see 500MB to 1GB of updates in single update run .. all my apps are
c) streaming music / movies .. seems when we ramp up streamlining of music or movies . memory leak grows faster .. ie within hours of clean start
c) large syncs of music or videos to ipads or iphones .. noticed that get big problems when I rebuild an ipad .. I typically have 60+ GB of data in terms of apps / music / videos to load .. have to do rebuild in phases due to periodic lockups

Firefox has a memory leak and I need to update it, but I want to keep 3.5 because I don't like how the newest version of Firefox is set up.

My computer is running low on RAM, and when I look at what processes are using the most memory, firefox is the number one using between 28,000 to 93,000k, so I'm guessing that it has a memory leak.
And because of that memory leak I have to update firefox, however I really dislike the newest version of firefox and I'd prefer to stick with the version I have, which is 3.5.

Often the memory problems are not just from Firefox in isolation, but partly relating to all the extensions available for it and then the videos and animations it runs on media rich sites.
The first thing to do is to upgrade to firefox 3.6 which is at least a supported version (Maybe not for much longer)
* see [[updating firefox]]
Next version after 3.6 is 4, you should avoid that, it did have some memory problems, that were worse than 3,6 and firefox 4 is no longer secure or supported.
The techies at Firefox have been working on memory problems recently and have made many improvements, but some of these improvements are only seen in the trial versions of Firefox.
I would in fact suggest you upgrade to Firefox 5 the current release version (soon to be replaced with Firefox 6)
I am able to run Firefox v3.6 to v8 on legacy XPs with less than 1GB RAM. Firefox in itself is not necessarily very demanding in terms of RAM. I am not sure what the figures are you are quoting, or whether they are high. ( Note 1Gb is in the order of 1 000 000 k )
As for not liking the set-up of new versions of Firefox, there is quite abit that can be changed, maybe you would be able to configure it more to your liking with little effort.

Custom MediaStreamSource and Memory Leaks During SampleRequested

Greetings,
I have a nasty memory leak problem that is causing me to pull my hair out.
I'm implementing a custom MediaStreamSource along with MediaTranscoder to generate video to disk. The frame generation operation occurs in the SampleRequested handler (as in the MediaStreamSource example). No matter what I do - and I've tried a
ton of options - inevitably the app runs out of memory after a couple hundred frames of HD video. Investigating, I see that indeed GC.GetTotalMemory reports an increasing, and never decreasing, amount of allocated RAM.
The frame generator in my actual app is using RenderTargetBitmap to get screen captures, and is handing the buffer to MediaStreamSample.CreateFromBuffer(). However, as you can see in the example below, the issue occurs even with a dumb allocation
of RAM and no other actual logic. Here's the code:
void _mss_SampleRequested(Windows.Media.Core.MediaStreamSource sender, MediaStreamSourceSampleRequestedEventArgs args)
if ( args.Request.StreamDescriptor is VideoStreamDescriptor )
if (_FrameCount >= 3000) return;
var videoDeferral = args.Request.GetDeferral();
var descriptor = (VideoStreamDescriptor)args.Request.StreamDescriptor;
uint frameWidth = descriptor.EncodingProperties.Width;
uint frameHeight = descriptor.EncodingProperties.Height;
uint size = frameWidth * frameHeight * 4;
byte[] buffer = null;
try
buffer = new byte[size];
// do something to create the frame
catch
App.LogAction("Ran out of memory", this);
return;
args.Request.Sample = MediaStreamSample.CreateFromBuffer(buffer.AsBuffer(), TimeFromFrame(_FrameCount++, _frameSource.Framerate));
args.Request.Sample.Duration = TimeFromFrame(1, _frameSource.Framerate);
buffer = null; // attempt to release the memory
videoDeferral.Complete();
App.LogAction("Completed Video frame " + (_FrameCount-1).ToString() + "\n" +
"Allocated memory: " + GC.GetTotalMemory(true), this);
return;
It usually fails around frame 357, with GC.GetTotalMemory() reporting 750MB allocated.
I've tried tons of work-arounds, none of which made a difference. I tried putting the code that allocates the bytes in a separate thread - no dice. I tried Task.Delay to give the GC a chance to work, on the assumption that it just had no time
to do its job. No luck.
As another experiment, I wanted to see if the problem went away if I allocated memory each frame, but never assigned it to the MediaStreamSample, instead giving the sample (constant) dummy data. Indeed, in that scenario, memory consumption stayed
constant. However, while I never get an out-of-memory exception, RequestSample just stops getting called around frame 1600 and as a result the transcode operation never actually returns to completion.
I also tried taking a cue from the SDK sample which uses C++ entirely to generate the frame. So I passed the buffer as a Platform::Array<BYTE> to a static Runtime extension class function I wrote in C++.
I won't bore you with the C++ code, but even directly copying the bytes of the array to the media sample using memcpy still had the same result! It seems that there is no way to communicate the contents of the byte[] array to the media sample without
it never being released.
I know what some will say: the difference between my code and the SDK sample, of course, is that the SDK sample generates the frame _entirely_ in C++, thus taking care of its own memory allocation and deallocation. Because I want to get
the data from RenderTargetBitmap, this isn't an option for me. (As a side note, if anyone knows if there's a way to get the contents of an RT Window using DirectX, that might work too, but I know this is not a C++ forum, so...). But more importantly,
MediaStreamSource and MediaStreamSample are managed classes that appear to allow you to generate custom frames using C# or other managed code. The MediaStreamSample.CreateFromBuffer function appears to be tailored for exactly what I want. But there appears
to be no way to release the buffer when giving the bytes to the MediaStreamSample. At least none that I can find.
I know the RT version of these classes are new to Windows 8.1, but I did see other posts going back 3 years discussing a similar issue in Silverlight. That never appears to have been resolved.
I guess the question boils down to this: how do I safely get managed data, allocated during the SampleRequested handler, to the MediaStreamSample without causing a memory leak? Also, why would the SampleRequested handler just stop getting called
out of the blue, even when I artificially eliminate the memory leak problem?
Thanks so much for all input!

Hi Rob -
Thanks for your quick reply and for clarifying the terminology.
In the Memory Usage test under Analyze/Performance and Diagnostics (is that what you mean?) it's clear that each frame of video being created is not released from memory except when memory consumption gets very high. GC will occasionally kick in, but eventually
it succumbs.
Interestingly, if I reduce the frame size substantially, say 320x240, it never runs out of RAM no matter how many frames I throw at it. The Memory Usage test, however, shows the same pattern. But this time the GC can keep up and release the RAM.
After playing with this ad nauseum, I am fairly convinced I know what the problem is, but the solution still escapes me. It appears that the Transcoder is requesting frames from the MediaStreamSource (and the MediaStreamSource is providing them via
my SampleRequested handler) faster than the Transcoder can write them to disk and release them. Why would this be happening? The MediaStreamSource.BufferTime property is - I thought - used to prevent this very problem. However, changing the BufferTime seems
to have no effect at all - even changing it to ZERO doesn't change anything. If I'm right, this would explain why the GC can't do its job - it can't release the buffers I'm giving to the Transcoder via SampleRequested because the Transcoder won't give them
up until it's finished transcoding and writing them to disk. And yet the transcoder keeps requesting samples until there's no more memory to create them with.
The following code, which I made from scratch to illustrate my scenario, should be air-tight according to everything I've read. And yet, it still runs out of memory when the frame size is too large.
If you or anyone else can spot the problem in this code, I'd be thrilled to hear it. Maybe I'm omitting a key step with regard to getting the deferral? Or maybe it's a bug in the back-end? Can I "slow down" the transcoder and force it to release samples
it's already used?
Anyway here's the new code, which other than App.cs is everything. So if I'm doing something wrong it will be in this module:

Again, I can't see any reason why this shouldn't work. You'll note it mirrors pretty closely the sample in the Windows 8.1 Apps With Xaml Unleashed book (Chapter 14). The difference is I'm feeding the samples to a transcoder rather than a MediaElement (which,
again should be no issue).
Thanks again for any suggestions!

Memory Leak with GotoAndStop()

I am trying to track down a solution to a memory leak within an embedded video. If I embed a video on the timeline and then run gotoAndStop or gotoAndPlay to a specific frame every time the frame changes it takes in more memory until it crashes at about 1.7GB however if I run a straight play() on the same clip the memory usage remains constant. I have also tried System.gc() as it is an AIR App and have tried unloadAndStop() with the embeded video being loaded into a Loader and neither can reclaim any memory.
I am looking for a a way to resolve the memory leak or another way to be able to rapidly jump to specific frames of video as far as I know this is not possible with external flvs.
Thanks
Dave

video is much like a .gif file. if you start at frame 0 and jump to frame 30 it needs to redraw what it does nt have in frame 30 which means tellign it to start at frame 30 is the same as telling it to get all information from when it last changed which might be frame 27 to complete the frame of what should display on frame 30.
this is why its slow to play backwards. and best to play an flv forward.
what i would suggest if you do not need video persay, would be to use png sequences. but if your videos are long then i suppose it would be a greater advantage to keep it compressed.
what is the quality as well of the video and its size and your frame rate?
You mention that you are creating a 3d view, how is that? do you use more than 1 swf ?
I still think this does not sound like a play head issue, since the video is already compiled.

Memory leak in video ...
