FMS H264 recording FLV format

I am trying to record a H264/AAC streamin FLV format on my FMS server and all I get in the recording is the metadata but no media content. Is H264 recording only supported in F4V?
Siva.

Yes FLV format does not support H.264/AAC content. You need to use the F4V container (or a MPEG-4 container) to record H.264/AAC content. From FMS 3.5.3 RAW file format is also supported which can hold H.264/AAC content. You can read more about it at http://help.adobe.com/en_US/FlashMediaServer/3.5.3/FeaturesGuide/flashmediaserver_3.5.3_fe atures.pdf

Recorded FLV files contain corrupt timestamps

Howdy -
I'm running FMS 4.5.3 r2005 on standard AWS Linux box. I'm recording the streams using NetStream.publish("appendWithGap") from a small custom Flash app running on IE+Windows.
Usually, the generated .flv file is fine. However, I've found a number of cases where the .flv file generated was corrupt. By using ffprobe -show_packets I'm able to see that the presentation timestamp (PTS) of sequential packets occasionally remain the same. This happens for both audio and video at times. For example, consider the output of the command:
$ ffprobe -show_packets saved.flv | egrep -e '(pts=|codec)'
codec_type=video
pts=0
codec_type=video
pts=0
codec_type=video
pts=0
codec_type=video
pts=0
codec_type=video
pts=0
codec_type=video
pts=0
codec_type=video
pts=3912
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
I really don't know much about the internals of the FLV format, but I assume that invalid timestamps like these make for a non-playable (corrupt) video.
Any idea what may cause FMS to record such a video?
What kind of information would be helpful to debug this?
Obviously, my client expects every video recorded to be one that an be played back, and so these corrupt videos are alarming to say the least.
FYI, due to privacy restrictions I can't share the recorded video without a signed NDA. If it would help, I can provide the entire output of ffprobe.
Thanks,
Ben

Flvcheck has validated the format of file, and it is correct. The logs "Adding Silence message" indicates that audio message was expected and is not recieved after a particular time check, because of which video may appear stalled.
Flvcheck may claim the file is valid, but event after running flvcheck -s the video is corrupt. According to ffprobe, many of the timestamps are still the same. When I attempt to play the file in an flv player, the entire video is run through up front in sort of a fast-forward view, and then the audio plays out more or less normally.
This makes sense, as the video player is probably playing all these frames with the same timestamp sequentially, which makes for the fast-forward effect.
To debug this issue, a good starting point would be, validating the input to FMS. FMS records what is published to it.
Does FMS tinker with the video frame timestamps, or are they just passed through to the file system?
Since you are able to reproduce this issue, can you please enable livestream logging and check if input stream to FMS is different from what it is recording.
Unfortunately I can't regularly reproduce it - though it does happen on a somewhat regular basis (it was happening a couple times a week).
Is it safe to turn live stream logging on for a few days to see if I can catch this issue happening? Or, will live logging chew up resources and cause issues?
Thanks for the assistance!

Pusblish Abode Connect meeting records (.flv) over Adobe Media Server - What is the easiest way?

Hi,
my name is Robin Schröder. I am a member of the univertity “Hochschule Hamm Lippstadt” from Germany.
We r using the adobe connect already. We wanna create offline videos of meeting records and publish them over adobe media server. The offline videos are in the .flv format.
Do I have to convert the .flv into mp4 (h264 & AAC) before streamable with hds and hls?
I read about f4fpackager that this program can convert .flv into .f4m – but it failed with error 999….. I checked the .flv file with flvcheck before: success!
The sample Video worked fine.
So my question:
We wanna publish all .flv recordings over the Adobe Media Server (VODs). What is the easiest way to achieve this?
Convert .flv in a streaming format (mp4?) - HOW?
Create multi-bitrate versions from the video - HOW?
Create f4m file for adaptive bitrate streaming - manually?
Publish hds & hls URL in the html site (decryption for url possible?)How can I realize a iPad/iPod/iPhone switch in the html Code for HLS/HDS switch?
Thanks!

Hi,
I'm receiving the information that "No backups available.", but if i log in my icloud I find the backup.

Problem about playing h264 in flv file

I read an article at "
http://www.kaourantin.net/2007/08/what-just-happened-to-video-on-web_20.html"
which is a blog of an software engineer of Adobe, the author said
in this article that "...There are functional limits with the FLV
structure when streaming H.264 which we could not overcome without
a redesign of the file format..." and "...Specifically dealing with
sequence headers and enders is tricky with FLV streams...", does
anybody know what exactly the author mean? what is the "functional
limits"? how to "specifically dealing with sequence headers and
enders"? is it a way to solve the "functional limits"?
Thanks!

I believe that it just mean that H.264 encoded video for FMS
& Flash are not stored in FLV format... because of some
inherent limitations in FLV file format.
It uses mp4/MOV format which is what has been used by
Quicktime also for quite some time. Adobe calls it M4V.

Recorded FLVs manipulation

Hi,
I'm creating a Flex application that enables users to communicate in a kind of video chat room. I only allow to live streams at any given moment.
I'm using FMS to record the videos in FLVs.
What I need to do is post process those videos and create a single video with all that happened in the video room. That means that I need to combine 2 videos, reduce the size of one of them so it appears over the other one. In other words one video will use the whole space an the other will appear at the upper left corner (over the other video,).
I need a server side solution for this. I created another post here and someone suggest a screen capture solution. That would work perfectly, but since this appliction will be used for several people and any time, I want the process to be automaticaly not manual.
So, I'm thinking I can do it with FFMPEG, but I need a way to identify in which order I need to compose the videos. Something like adding a time stamp to each FLV in FMS (when they are recorded). How can I add custom metadata to the FLV? would I be able to read it later? any ideas will be appreciated.
Tks.

You can add custom metadata using ns.send method but this"ns" ie netstream should be the publishing netsream. So you can use the Flash Player client which uses webcam to publish using ns.publish and then again use the same ns to insert custom metadata by calling ns.send. Here is a sample code snippet:
function netStatusHandler(event:NetStatusEvent):void
trace("In netStatusHandler...");
    try
   if(event.info.code=="NetStream.Publish.Start"){
   setCustomMetadata();
    catch (error:TypeError)
        // Ignore any errors.
function setCustomMetadata():void{
ns.send("onCustomData", "hello");
To retrieve this you need to use following client code:
if(info.code=="NetConnection.Connect.Success"){
ns = new NetStream(nc);
ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
client = new Object();
ns.client = client;
client.onCustomData= onCustomDataHandler;
function onCustomDataHandler(str:String):void{
trace("onCustomData: " + str);

Sending streaming recorded FLV to end and stop

I'm having a surprisingly hard time doing this. I have a
recorded FLV which multiple users are simultaneously pushed into
starting via a NetStream, streamed off of FMS. What I would like to
do is allow the presenter to at any time push everyone, no matter
where they currently are in the video, to the very end of the
video, and stop the play, and have the last frame/keyframe of the
video stay up on their screen. How would this be done?
Thanks.

Abeall,
You would need to have the presenter call a function on each
client connected to put the subscribed netstream at the duration
point of the stream.
For example, you could use the NetSetream.send method to send
a function call to all subscribers like this:
// This is on all client NetStreams that are subscribed
// __ns is the NetSteam that you play
__ns["owner"] = this;
__ns.receiveMessage = function(){
this.owner.__ns.seek(__ns.duration);
this.owner.videoPlayer.stop();
// Presenter function to set all clients video player to end
of stream
// __ns is the NetStream that you publish
private function onSetStreamToEnd():Void
__ns.call("receiveMessage", null);
This will only work for non-live streams.

Recorded FLV just stops after a random time

Hello:
I have some long (1 hour or so) flvs recorded from a small
flex app communicating with FMS 3.0.0. It is mostly audio.
When replaying them from
- a client Flash OR from (Method A)
- FMS and then have a Flash client connect to the FMS Live
stream (Method B)
The stream just stops after a while (variable: could be after
2 minutes or 20 minutes). It is very reproduceable which makes me
wonder how come others are not getting this as a google search does
not show other complaining.
I get an Unpublished and then Stop status on the Flash Player
for the stream.
Strange thing: If I play the stream direct from a player
(Method A above), then the higher the BufferTime and the longer it
takes to stop. With a buffer time of 5 seconds, it plays without
stopping.
I actually need to run it with Method B. Setting all kind of
buffers on the server produces no noticeable results.
Any idea?
I can send you my simple test codes for Flash player, FMS and
the flv if need be.
Thank you

Fms user recorded audio fail in FP 10.1.82.76

hi all,
I have a small app that uses FMS to record the user voice and then play it. It's not working *anymore* with the latest FP
In my tracking It records the voice, it generates the file (if i download I was able to listen to it), but if I try to play, it doesn´t play. If I use FP9 r124 it works, using FP10r53 or the latest 10.1.82.76 it fails !!! all with the same SWF
has anyone experienced the same? I can not ask everyone to downgrade the flash player.
I tried to look in here http://kb2.adobe.com/cps/838/cpsid_83808.html#main_version but couldn't find any details about this specific problem.
here is the test, http://www.alumni.org.br/elearning/e.html
any sugesstion are appreciated.
thanks!
rodrigo

hi mamata, thanks for your intrest.
Do you publish the audio to FMS through a Flash IDE or through some other publisher? And which codec are you using?
from the Flash 8/CS3/CS5 IDE it works ok I can record and listen. Uploadong this same swf online the *the listening* doesn't work. I really don't know the coded.. How can I find this ?
here is what I got up to now:
a) I saw on a forum that the NetConnection should have the entire path to the "instance app" and then new Stream should have *only* the filename (without extension) but it didn't work. I change it to do exactly this and it didn't work either. The
I reaaly would some light on this?
b) here: http://www.justskins.com/forums/netstream-publish-badname-109090.html I got this:
"The technical support guys (from the FMS Hosting) told me that this error is occurring because there is a saturation in the amount of streams that server is configured to handle. That's why once the limit is reached, no client can publish any more streams and they get the BadName error.
Now they've increased that limit and the app has been working fine."
is there a way to know the amount of steams that r setup in my server?
c) here is an example:
http://www.alumni.org.br/tmp/rodrigo/gravar/c.html
this one was published to FP10.
I use the firefox extension Flash Switcher to switch the FP,
loading the example using flash player 10.1 r53 I can record the audio, I can see the generaterd flv file in the FMS server but it doesn't play it
switching to FP 9.0 r124 it works ( you don't have to record again, just clicking play it will play the stream recorded with FP 10.1. r53) or you can record AND play....
*it's a huge problem and I'm desperate because I have hundreds of users that have this tool avaliable and I'm getting a LOT of complains.*

Folder location of pre-recorded flv file

I have a pre-recorded flv file that I've placed in a
sub-folder within the applications folder of Media Server. When I
run my Flash movie within Flash or on my localhost using IIS, the
Media Server Management Console shows my flv streaming. This only
seems to work, though, if I also have the flv file in the same
folder or sub-folder relative to my swf and html files and the
contentPath perimeter of the on-stage video component points to
this flv folder/sub-folder. Question: does the flv need to be in
both these locations? The documentation is not clear about
this.

This makes me suspect that you're not actually connecting to
FMS, but rather, just playing the progressive http video. If you
leave the flv in the http directory (and remove the file from the
fms directory) does it still play?
If you want to connect to an FMS stream, your content path
will be an rtmp location, not an http location. It will look
something like this:
rtmp://myfmsserver.com/myApplication/myVideo
I don't use the prefab media components, so I don't know if
it wants the .flv extension at the end of the url.

The SCRP_CODE column has a NOT NULL constraint. The ORA-01407 error is telling you that you cannot update or set a value for this column to null because of the constraint. This has absolutely nothing to do with an index. You can use a marker/sentinel value in lieu of using NULL. For a numeric field, where everything is positive, a negative value (-1) can be decoded as meaning null. For a character field, a code such as NA can represent NULL.
This also has nothing to do (directly) with GoldenGate failing because of this error. The underlying SQL statement will fail everywhere, regardless of the tool or application. It is not a case of failing only in GoldenGate.

Converting .MOV video file into FLV format?

Hello, I finished editting a corporate video for client and they want to know if I can also send them an FLV format video.
Does anyone know how I can do this. I edited video in Final Cut Pro and used Compressor to export my final .mov video file.
How do I make this a FLV file?
Thanks~

The best method would be to use a Flash encoder to transcode the video. Do you have a Flash encoding application?
Another method would be to export an H.264 file of the video. When it's finished, change the file extension to .flv. It should play in later versions of Flash player, but won't play in older versions.

It takes 11 hours to convert to flv format from Quicktime

I edited a DV movie from camera using FCP and one hour final movie after adding all animations and effects in .mov format which was about 12 GB takes about 11 hours to be converted to flv format is this usual or I need to do some thing.
My system configuration is
Power PC G5
3500 MB RAM
1.1 TB hard disk.
I used Marcromedia Flash Encoder
OS Mac OS X 10.5.8
is there some thing that can be done to shorten the time as the compressor of FCP wont submit batch.That is an error I am getting in it.
http://support.apple.com/kb/TA47672?viewlocale=en_US
and any of the solution suggested above does not seems to work.
This post is not about compressor problem I had asked that on another thread
http://discussions.apple.com/thread.jspa?threadID=2374397&tstart=0
but it says to install an old OS which is not some thing logical I feel to be able to use compressor I wont be downgrading my OS.
What I want to know is to be able to convert to flv from .mov format so much time is it a usual thing or some thing can be done to shorten it.

That's what I meant. You just need a good compression codec.
Can you help to identify or let me know a few codecs I will try.
Is FLV the only resource you streaming server will use?
Yes it has to be flv.The decision is not in my hands it will be a Linux Server so if you are aware of any better file format let me know.I can suggest.
You can use hardware compression systems to go directly to several different >low grade codecs but I've never used them.
I do not have any such hardware but anyways
thanks for this suggestion.

Flash player flv format

hi guys looking for some assistance,
I have lots of video files i wish to place in my website. These videos are all AVI format and i have been told this is too large for the web and it would be better to convert them, so off i went and purchased sony vegas and camtasia studio to do just this. Now im told flash is the best format for the web but i see no flv option in any of these applications (am i missing somthing). So i have the choice of mov, wmv or MPG4 so after trying them all looks like MPG4 is the best, however when i convert i end up with several files MPG4, SWF and an html so this is confusing me. Im kinda new to the Media side of things and would like some info. My videos range from 8 to 15 mins i wish them to be converted in such a way they will require a flash player to view can any one assist.
IF FLASH flv IS THE BEST FORMAT WHY DONT SONY VEGAS OR ANY OTHER CONVERT TO THIS......????????
Thank You

Greets!...
File-import - select import video option.
All the videos are converted to flv format. But you install qicktimer player install your system.

Using php script (ffmpeg) convert to flv format

I would like to know the list of possible output (export) file codec from FCP X. For example, can I export in F4V or FLV format?

I would like to know the list of possible output (export) file codec from FCP X. For example, can I export in FLV format? Where do I find the list, which gives me all the details about it? Or is there only one output codec? Thanks

That's an excellent analogy. While FCP cannot export FLV. It is possible to do a very simple substitution. If you export a QuickTime movie using the .mov suffix with the H.264 codec, you can change it to FLV simply by changing the suffix to .flv. This is an acceptable format for Flash movies on most web sites, if that's where you're trying to go.

Adobe premiere cc .flv format not supported

Hello,
When I import .flv format file. Error: not supported.
Can I help you?
Thanks,
Max

Sorry to hear of your issue, but did see that you were able to roll-back, and get with your Project.
FLV Import support has been a bit of a mixed bag. Going back several versions of PrPro, one could purchase an inexpensive, and very good, FLV Importer plug-in from Moyea, a 3rd party supplier of many things FLV-related. Then, with PrPro CS 4, that plug-in would not function, though with about the second update to CS 4, Adobe did add FLV Import support, with just a few limitations.
Then, Apple declared war on Flash, and recently, Adobe dropped FLV Import with CC. Wonder if they are trying to "make nice" with Apple?
I sort of doubt that Moyea, or anyone else, will write an FLV Import plug-in, as CC will be constantly changing, and I am not sure that such effort will be rewarded with adequate sales.
I am also surprised by Adobe's dropping FLV Import, but that was how I felt, when I found that Encore had been dropped. Finding out the reason for Encore's demise did not diminish my sadness, but that is just how it goes in the changing world of video. Now, with streaming content being the big focus nowadays, I wonder if Adobe is sending a somewhat subliminal message about the future of Flash?
Just some thoughts, and at least I have some older versions of PrPro, and that old Moyea plug-in, should I ever need to Import FLV's.
Also, thanks for stating your workflow, regarding FLV's, as that makes perfect sense.
Good luck,
Hunt
