H.264 performance optimization, and gstreamer for coreavc
Locked
 
|
Hi,
I'm working on gstreamer to improve H.264 decode performance on multi-cpu PC, ffmpeg's H.264 decode's performance seems not very good (can only run on one cpu one hyperthread). According to mplayer's document, using wine+dshowserver+coreavc is one way which can significantly improve H.264 decode performance, but I can't find any gstreamer element/plugin using coreavc/dshowserver, So I'm writing one. So does anybody know whether there's such element (using coreavc+dshowserver, just like mplayer) or plan for such element? And is there any other way to improve H.264 decoding performance, including use multi-cpu or any other way? Thanks a lot.

One way might be to write you own codecs + gst plugin, optimized for multi thread utilization.
Typically embedded platforms have such codecs desiged as per there specific need. Best -kapil

FFmpeg has multithread support I think. Are you sure you can no try to
build ffmpeg and gst-ffmpeg correctly to get proper multithread support ? I have been comparing the ffmpeg multithread performance with Fluendo's H264 decoder and they are pretty similar using all the cores.

Strange, I was sure I've seen decoding of H264 through ffmpeg happen
on multiple cores... I will double check... Julien Moutte, FLUENDO S.A.

Thanks for reply so soon.
I've seldom posted in this maillist, so you really encourage me a lot. I've not yet tried ffmpeg multithread version, and will try it recently. Since you've compared ffmpeg multithread with Fluendo's H.264 decoder, have you compared CoreCodec CoreAVC with Fluendo's H.264 decoder? are they similar too?

Hi Kapil,
Thanks for replying soon. I've finished my gst plugin using wine + coreavc + dshowserver. I just follow http://code.google.com/p/coreavc-for-linux/ , and port it's mplayer coreavc patch (vd_dshowserver.c) to gstreamer. It works, but everytime I start my H.264 decode through wine, it takes one more second to start, and whenever system bootup, it takes wine 5 more second to start my decoder, so I'm working on it. So far, I've not compared coreavc(especially with wine) with ffmpeg-mt and fluendo's H.264 decoder yet. Also, I haven't compare performance between coreavc+wine in linux and coreavc in windows, so I don't know whether there's a performance lost in wine.

Hello Karma,
Curious why do you so much want to use coreavc codec ? If it needs wine to run , its anyways not a great idea to use such codec on linux natively IMHO. Best Kapil

Hello Kapil,
I agree with you, anyhow need wine is not a good idea. Blush, because a few days ago when I realize that I need to optimize H.264 performance, I don't know much about how ffmpeg/mplayer multithread is going on. Also at that time, after some google work, someone said that coreavc is quite good, and since there's already coreavc-for-linux project there, I tried and found out it's really simple for mplayer+coreavc+wine to work, and the source code is also very simple (vd_dshowserver.c). So that's why I write a gst plugin for coreavc. Now since you have told me about ffmpeg multithread, of course I'll try it, if its performance is similiar to coreavc and Fluendo's H.264 decode, ffmpeg-mt will be the right choice. Again thanks for your to give me directions.
