VTDecoderXPCService using 98% CPU Choppy Video

Hello,
When I try and play movies in Quicktime they play in slow motion but the sound is in real time. Other programs play the video choppy. I noticed that VTDecoderXPCService is using 98% CPU when running video. I am running the latest Lion 10.7.4 on a new Mac Mini with 8 GB ram. I have noticed my system getting slower latley.Have 200GB free on the 500GB Hard Drive. Safari is slow and If I run certain programs my mouse cursor starts dragging when moved. Any Ideas?
Thanks

I would be nice to get some feedback on this. I really struggle to accept having to switch to the 9600 card every time I want to watch a DVD.
The performance update did not do the trick, I must admit though that I haven't had any avi freezes in quicktime for a while.

Mdworker still using all cpu + poor video performance

I had an older macbook 1,1 and installed a new HDD and increased the RAM to 2 GB. I did a clean install of Snow Leopard, did all the software updates, then I migrated applications and files from my old disk that was Tiger 10.4.11. I copied all of my music and pictures from an external drive onto the new HDD, so I put about 140 gb of new data on the new drive after Snow Leopard was installed.
It's been on for a week now and mdworker is always using 40-80% of the CPU. I have force quit the process but it seems to keep coming back. I also unchecked all the boxes in the Spotlight preferences and that has not changed anything.
According to activity monitor mdworker process had read over 15 TB before I killed it, the HDD is only 500 GB.
How can I get this cpu hog to behave better?
I am not sure if it is only due to the mdworker issue, but ever since the upgrade my computer can not render video about 360P resolution without freezing up. Videos I could watch before the upgrade now lock up the system. I have also found Quicktime 7 seems to run better than Quicktime 10. Can I get rid of the newer Quicktime or make 7 the default for files and streaming video?

Reply,
I already ran all of the diagnostics in Onyx tool, which I am pretty sure runs the same or very similar disk checks.
Thanks for your respoonse.
I put the HDD in privacy and now mdworker is not running. I can live with out spotlight. I read somewhere (that I can't find any more!) a way to read the logs of mdworker to see if it is getting stuck on a particular file and ending up in an infinite loop. There's no way it should take a week to index a 500 GB drive.
Still have issues with Quicktime being very slow and stalling. Videos ran better on Tiger, both streaming off the web and files on my machine are really choppy and will freeze up with this now.
I am very close to restoring 10.4.11 on the system and giving the SL DVD to a friend. Beginning to think this machine is just not fast enough for this OS. Even though I maxed out the RAM and have a lot of free disk space it is slower than Tiger.

I have Adobe Elements 9 and I used to be able to export HD 1080p videos with no issue. But recently, when I export using H.264 MPEG or MPEG 2, which I normally used, the high resolution videos come out very choppy. How can i fix this?

Are you running the 9.0.1 Update of the program and on what computer operating system is it running?
Is your video card/graphics card driver up to date according to the manufacturer of the card?
Is your computer optimized, including maintenance of pile ups of preview files, conformed audio files, and conformed video files?
Do you have the latest version of QuickTime installed on your computer with Premiere Elements 9.0/9.0.1?
What are your project settings and what are the properties of your source media? When you say that "used to be able to export...." is that on the same computer, same brand/model/settings for the camera recording the video now in use, same Premiere Elements 9.0/9.0.1?
Where player are you using for the playback of these exports?
Please give us more details on the size of the projects (then and now) as well as details of the customized export settings in your Share/Computer/ route. Premiere Elements 9.0/9.0.1 is only a 32 bit application running in 32 bit or 64 bit system. Not sure if computer resources might be taxed more so now than before.
More later.

I am considering a base 21" iMac ($1099 @ Best Buy) for home use. It would be my first Mac. Is the base model powerful enough for everyday home use and some light video editing or should I upgrade the CPU, Ram and to a Fusion drive?

Purchasing with the upgrades through Apple would add about $800 over the Black Friday deal at Best Buy. Just looking for some advice if I will be satisfied with the based model.

All models will do what you want. Upgraded models will do it faster than the standard models.
Just why are you thinking of switching to a Mac?

Adobe flash player uses 250% of my cpu playing videos...how is that possible?

Adobe flash player uses 250% of my cpu playing videos...how is that possible?

That is totally possible if you do not have Flash set to
enable hardware accelerations. Right click on a playing
Flash video and select settings from the pop up.
Click the little monitor icon at the bottom left corner.
Check the check box "Enable hardware acceleration."
With out this set, the CPU does all the work of decoding the
video instead of the video card.
update:
As a quick check, went to Hulu and started an episode of
Warehouse 13. With hardware acceleration enabled, CPU
was at 37% for Flash. With hardware acceleration disabled,
this jumped up to 138%.
The test was done on a 2011 Mac Mini Server 2.0 GHz, quad core i7.

Choppy Video/Audio with FMS 2

Hello,
My internet group and I have been trying to get the bugs
worked out of our system so our Flash Media Server (version 2.0)
will work correctly. The latest issue under our load test was
choppy video and audio. The load test was to see if our network and
hardware could handle 15 concurrent connections and of course
something caused the test to fail. Our network and server engineers
say their stuff all checked out only used 20% of network bandwidth
at the most. The server barely hit 5% CPU usage. It has been
suggested a few different times to incorporate a buffer. I don't
really want to do this, because it seems to be a patch on a problem
somewhere. Plus, I also read that buffers in streaming video are
somewhat irrelevant because as soon as the user seeks forward or
backward the buffer is dumped, which would put me right back in the
boat with choppy video again until the server is able to establish
another buffer while streaming the video.
Here is some info on the video we used for test:
- 400kb per second
- On2 VP6 Codec
- Frames per second (same as source) (video was ripped from
dvd quality quicktime file.)
- 96kbps audio
- 720 x 480 video size (The reason we went so large on the
video is because we wanted to test a “worse case
scenario” if a video that size were ever requested we would
know if it was possible.)
- Running on Windows 2003 server and FMS v2.0
Here are my questions:
1. Shouldn't the FMS stream a video of this size to 15
concurrent connections without experiencing any kind of lagging or
choppy video?
2. Should I incorporate a buffer into the video to smooth
over the choppy places?
Thank you for your help!
Eric

Good to know...I have to admit that it is a little difficult
to find good tutorials on this kind of stuff. I've spent the past 3
hours trying to find a tutorial on how to get the "dual buffer"
technique with FLVPlayback since FLVPlayback seems to be the option
that Adobe steers most people to use. Maybe because that's the
easiest way to get video up and running for new comers (like myself
to flash video) like the Spry stuff in Dreamweaver. I've never used
the Spry stuff because I hear it's bulk, plus I already know how to
create most of that stuff with only what I need. It sounds like Net
Stream is the way to go, but will require more work to get the end
result I want.
Obviously, I don't know much about the whole streaming video
stuff, but I guess I'll be considered an expert if I can ever get
this FMS utilized properly and my Net Stream up and running. My
understanding when we bought this server was that it was pretty
much plug'n play and the FMS ensured smooth video playing with no
problems. I didn't know I had to do all this...
Thanks again fmslove!

Elements 10 Playback uses 100% CPU 0% GPU

When I play back a video clip in the Elements 10 environment the video is choppy and my system is using 100% CPU and 0% GPU. When I play back the same files in Sony PMB the CPU runs at about 15% and the GPU runs at about 50%.
Is there a way to get Elements 10 to use the GPU?
System Specs:
Windows Vista SP2
AMD Athlon 64 X2 Dual Core 5600+ 2.8GHz
3 GB RAM
ATI Radeon HD 2600 XT
Video Files are 1080i 5.1 m2ts.
I am using the trail software now and will buy if I can get it working.
Thanks!

Certainly when rendering PRE uses as much of the processor capacity as possible (somewhere in these forums I posted a screen shot showing all my four cores at 100%).
But in normal use I don't notice it hogging all processor power. I wonder if you have selected the right project setting for your video.
What Sony camera are you using?
What format did you record the video in?
How did you get the clips onto your PC?
What project setting did you use when you created your project?
Do you see red lines across the top of the timeline when you first add your video to the timeline?
As you edit your clips the timeline will show red lines - to perform a render press [Enter] and wait for the lines to go green.
Are you using still images in the project? What pixel dimensions are they?

Choppy video on certain sites/flash players only

I bought an Acer laptop just this week. I've been having issues with video appearing rather choppy, as if looking at a poorly done animated gif. It's not constant, only on certain websites. For example I can watch a video on YouTube as smooth as cable tv but if I try to watch a video on Failblog.org I encounter very choppy video. At first I thought it was perhaps the quality of videos themself on these other sites, so i checked them out on my desktop and they play just fine. I tried disabling hardware accelleration, encounter the problem in both Chrome and IE, and have made sure I'm using the most recent version of flash. I'll post information below regarding my system and flash installation.
System:
Acer Aspire Laptop Model # 7741Z-4643
Processor: Intel Pentium CPU p6100 @ 2.00GHz 2.00GHz(DUAL CORE) with 3MB L3 Cache
Installed memory and storage: 3.00 GB DDR3 SDRAM and 250 GB HD with 189 GB free space
Graphics: Intel HD Graphics Dynamic Video Memory Technology 5.0
System Type: 64-bit Windows 7 Home Premium
Network: Wireless 802.11b/g/n
Flash:
In Google Chrome it states "You have version 10,2,154,12 installed"
In Internet Explorer it states "You have version 10,2,152,26 installed"
I've tried uninstalling and reinstalling as well from the control panel > programs > uninstall. The logo on your test/version page plays fine.
Protection:
Malware: Malwarebytes' Anti-Malware
Virus: AVG
I've disabled AVG from running in the background and on startup due to conflicts with malwarebytes and general resource hog issues I've had with it in the past. I've last scanned this morning and came up with no infections with both programs. Both have been updated to the latest libraries available for detection.
Any help I can get would be great and I apprecciate your time.

Converting to MP3 causes iTunes to Not Respond while using 50% CPU usage and makes my computer stutter

Anytime I attempt to "Createa an MP3 Version" of a track, it will take a REALLY long time to work.
Right now I am attempting to convert an audio book I have which has 88 tracks. Once I start to convert anything more than 1 track at a time, iTunes immediatly becomes "Not Responding" and takes up about 50% of my CPU the entire time. It seems like it's doing something in the background but it won't even update the screen anymore, creating weird effects on my screen (Ghost menu bars show up at the top of my screen, etc.). In addition, once iTunes becomes non-responsive, my entire computer starts to "stutter" meaning that every other second everything momentarily hiccips and stop for a split-second. This means that while iTunes is converting any multiple MP3 files, if I drag the mouse across the screen, it stops every other second. Any videos that I try to play pause every other second briefly. Basically, my computer becomes almost unusable. Plus, while iTunes is working in the background, different programs randomly jump to the front of the screen. I will try to be using my web browser while iTunes is working in the background. Then, suddenly, iTunes pops back up to the foreground in front of my browser (put still won't be responsive to clicks). My notes program will also flash windows in front of my web browser while surfing, again, only when iTunes is running in the background.
I really don't understand:
1. Why it takes so much time to convert any file to an MP3 file. Even converting a single track takes a few minutes. I'll let my Macbook Pro (with Windows) sit for HOURS upon hours trying to convert the 88 track audio book and it always freezes up and never comes back.
2. Why iTunes becomes non-responsive so quickly and won't allow the screen to update once it starts "thinking." It caps out around 50% of my CPU power so it's not like it doesn't have the headroom to refresh the screen while it works.
3. Why does iTunes' working in the background affect every other program I am running? I don't mind if it uses up CPU cycles in the background, but if it makes my computer unusable while doing so, it's really not worth it.
I should state that I love Apple products (even though I use Windows on my MBP for school purposes). However, I absolutely DREAD having to do anything with iTunes anymore because it has become such a hog on my computer. Someone please tell me that there is something wrong with my iTunes and/or a setting I should change. I have already re-installed iTunes from scratch before and that didn't help.

Not a solution, but if the Podcast feed is dormant, why not unsubscribe?
As to the file structure for media on the device it is deliberately obscured as a countermeasure to casual piracy. See Recover your iTunes library from your iPod or iOS device. Content put on the iPod by a non-iPod aware product is going to treat it like any external drive. The iPod firmware won't read that media.

Video Lagging/Choppy videos on Macbook Pro

Hello,
I am having a problem while watching videos online: video lagging/choppy videos. Sometimes the video is stuck in a certain frame although I still have the sound on the background; sometimes the video slows down completely (frame+sound). It started around one month ago, and exists in several different websites, I couldn`t solve it by myself. I am not very good with computers. I tried to uninstall/reinstall flash player, as well as disable hardware acceleration, and the problem is still there. Also somedays the videos are working fine, and somedays they are all bad independent of websites. I tried to use different browsers (chrome/firefox/safari), but the problem persists.
I am using a Macbook Pro and bought it in the beginning of January this year (right now it is running OS X 10.7.4) with flash player version 11.2.202.235.
I would very much appreciate if you can help me.
Thanks.

mellskucukoglu, uninstall all adobe products then install Adobe Flash Player, Adobe Reader, Adobe Air, Adobe Shockwave Player. Make sure to select the operating system correctly behind the link. Turn off your antivirus till you finish installation as suggested below the webpage. If it still doesn't work check for OS X 10.7.4 updates.
If it still doesn't work then go for Adobe Live chat in this link http://www.adobe.com/support/chat/ivrchat.html . Sometimes they are busy. If they can't help. Think about any changes that you made before this issue like installaling any new apps. Uninstall them. If it still doesn't work then install Adobe Flash Professional CS 6. After installing check for adobe updates and update them all. It should work at this point. If not ,watch this

Choppy Video on MEGA 180

Hi all,
I'm suffering from choppy video playback on my MEGA 180. By choopy I mean every ten seconds or so it will freeze up for a split second, the audio stays in sync, but you can slightly tell that the video stops, or skips.
This happens when watching .avi, DivX or even commercial DVD's. It also happens on my screen saver.
Since I was using the onboard video I thought I'd try using a video card but the same thing.
What I can't figure out is what the onboard video and a seperate video card have in common, since it's happening to both.
My onboard video has the latest drivers, and the PC as a whole is up to date.
Any suggestions are greatly needed.
Thanks.

can you give more information on the hardware you have installed in your Mega 180?
and can you give more background information; ie how long have you had this system, has it ever worked correctly, did the problem start after you installed any particular software, etc etc...

Choppy video playback with airplay from Macbook Pro

I experience very choppy video using airplay towards my Airplay unit (3rd gen).
I am using a Macbook Pro (15" retina, late 2013 version) with these specifications:
- Intel Core i7 2.7 GHz.
- 16 GB ram.
- 768 GB flash/SSD.
...and so on. I have the Mavericks OS installed (10.9.1).
When I duplicate or extend the screen of the computer to my Apple TV it is chopping EXTREMELY much. I am not talking a little bit - but it is not even watchable. I thought that it could be the router itself as the connection is (probably, correct me if I am wrong anyone) is directed from the computer - to the router - and then to the Apple TV, which could make the router like a filter in the process. And if something would prevent the signal from reaching the Apple TV with "full speed" it could prevent the actuall image.
However, when I am using the iPhone 4S and streaming video (both video found in my phone as well as streamed TV from apps such as Magine.com) the image flows completely flawless. There are not even a touch of lagging. It flows perfect, just as watching a movie directly on the TV.
The networking hardware in the phone is slower than in the Macbook Pro retina (late 2013) - both for sending and recieving data. But still... my iPhone works better than the Macbook Pro for the Apple TV. Even though that the processing, memory, graphic and networking power is probably a thousand times faster in the computer... it still performs really bad.
I have followed some discussion threads here (https://discussions.apple.com/message/22051725#22051725 and https://discussions.apple.com/thread/5734226?tstart=0 just as a couple of examples). I have accessed my router (Netgear Gigabit EVG 2000) and increased the Wireless mode to "up to 270 Mbps. I have also followed the previously linked threads and disabled the WMM (in the QoS-section). I felt that this made a little bit of a difference...
...when I am mirroring the screen and scale down the resolution to match the AirPlay screen (full-HD, 1920 x 1080) it works okay, but still chops quite a bit almost all the time. But if I extend the screen and want to watch TV at the same time as I am doing something else on the computer - then it chops so that it is not even possible to watch.
This have to be something either with the Mavericks OS or with my network settings - can anyone help me...? It would mean A LOT!

Curious why you think it would be my network when the same network is being used by the iPad 3rd Gen and iPhone 5 and they both stream without issue. As far as the other items you mentioned, all devices are up-to-date with the latest firmware/software and the latest MacBooks do not have ethernet ports. Speedtests that I have conducted also indicate that bandwidth is not the issue as the results show that the speeds received from the router are quite impressive.

Choppy video on big screens PLEASE HELP!

I've noticed that the videos that I have exported from CS3 are very smooth when played on a computer screen and average size tv screen, but are very choppy if played on a large TV or projected on the wall. Is there a way to remedy this? Please help!
Drew.

I think I figured out the issue. Thanks for all your advice. I'll repost if I have any other problems.

Subject: Choppy video on big screens PLEASE HELP!
Drew,
How is the large-screen projector connected, via a set-top DVD player to it, or by a computer connected to it? If it's via a set-top player, is it the same one used for the small-screen TV, or a different one? What is the make and model of the set-top player(s)?
Also, what DVD media was used, and what was the burn speed used to create the DVD? Was this authored in Encore, or with some other authoring application?
Good luck,
