h264 mkv stutters in playback

ADVERTISEMENTS
Page 1 of 21

I am trying to watch a 1280x720 h264 .mkv file on my computer.

My computer is an Intel 2.4 GHz dual core (E4600) with 2 gigs RAM and an nVidia 8800GT video card, running Windows XP. It should be able to play anything I throw at it, but I get frequent stutters using vlc 0.8.6f and the latest Community Codec Pack. I have checked to see if vobsub is installed and it is not.

What can I do? reply



I still think it’s the CPU choking. H.264 is a very processor-intensive codec, so even with the latest processor, you never know. Here’s how to check. When you play the video, right click on your taskbar and choose task manager and look at the performance tab. Is CPU usage at 100%? Then look at the processes tab, and click at the CPU tab once or twice to sort processes by CPU usage. Is the VLC taking close to 100% of CPU usage? Or is there another background process competing with it and keeping it from making use of the processor? If the latter, you could kill the process if it is a non-essential program, or try increasing the priority of VLC (right click, and pick a higher priority). reply

CPU is NOT Choking, the person who wrote that is tarded.

I have a celeron 430 that runs 720p MKVs fine with media player classic, but runs choppy with VLC. reply

Feedback


BTW, the celeron 430 is using onboard nvidia video from my crap ECS mobo.

Again, 720p MKV with this setup is smooth as glass.

1080p runs smooth also, but only with the CPU overclocked about 50 percent (this surprisingly runs stable)

This computer only plays movies, so it doesnt get junked up with prno malware. reply

That version of VLC doesn’t use both cores. The new one may. Install the K-lite codec pack and make sure your ffdshow settings are set to 2 threads, or 4 if your dual core.

to play 1080p h.264 you need a dual core chip based on the core 2 duo line, this includes core 2 duo, pentium dual core, and celeron dual core.

pentium D and Celeron D will NOT be enough for the beefy 1080p MKV files out there. reply

Hi guys,

People believe certain things about all this HD stuff and I for one got pretty confused so I decided to trial and error all the programs myself! Ignore all this frames/hz stuff, I found all that wasnt the problem, it is the codecs!

After faffing around for hours pssing the gf off something rotten I believe I have the answer!!!

I tried all the players out there but only 2 work 100% VLC & BS player!!!!

Try VLC first, it is simple!!!

You can speed up the H.264/MPEG-4 AVC playback by disabling loop filter for H.264 decoding. To do this go to Tools -> Preferences... (set Show Settings to All) and Input / Codecs -> Other codecs -> FFmpeg and in the drop-down box for Skip the loop filter for H.264 decoding change it to All. Remember to press Save to save VLC settings and restart VLC after that to make sure changes are enabled.

BS player:

* Uninstall all codecs (via add/remove programs)
* Install FFDShow codec pack (download from http://www.free-codecs.com/FFDShow_download.htm -- select SSE or SSE2 build -- do some research to see if your processor supports SSE2 [it should -- but double check])
* Install CoreAVC decoder pack (legit version costs ££ or try rapidfind.org)
* Open up the FFDShow video decoder control panel and for the “H.264/AVC” format, select “disabled” -- save & close
* Open up the CoreAVC decoder control panel and check the “Use Tray Icon” box -- save & close
* Install BSPlayer (http://www.bsplayer.org/) I got the bsplayerpro one!
* After installation, set all MKV files to open with BSPlayer (or all video files if you chose not to use VLC)

When you play MKV files in BSPlayer, the coreavc and ffdshow icons should pop up (two blue icons, one round other w/white background). If it doesn’t, then you didn’t configure FFDShow to disable the handling of “H.264/AVC” formats.

* If still slow turn off cuda acceleration in coreAVC !!! Stop here if all works, I havent tried the below out:

Hey presto, 2 x players both outputting hd with sound in sync!!!!!!!!!!!

Cheers

wipe0wt,

I did what you suggested for VLC, and I can’t believe that made such a dramatic difference. I have avoided 1080p files for so long. Thank you so much!!!
