Here is what I've been up to recently.
PyMedia is slower than mplayer or ffmpeg. It is for sure. But how big is the fish ?
Code:

video RE-11.avi 640Mb, 112099 frames

mplayer-1.0-pre6 - measured on ME6000
  demux+ parse video:    1299 secs( 86 fps )
pymedia-1.2.3.4-pre2
  demux+ parse video:    2115 secs( 53 fps )

Almost 1.6 times slower ! Is there any way around it ?
Yep. I have changed inside logic to better handle memory, allocations and copying. Here is the new result:
Code:

pymedia-1.2.3.4-pre4
  demux+ parse video: 1356 secs( 83 fps )

Looks good now ! Laughing
Comments ?

Well done!
You're the best Very Happy

I didn't think that a "python distro" can be as fast as a "mplayer distro" (like geexbox)... but I was wrong!

Your project Is the one I've been waiting for ages... Wink

Keep up the good work!

bye

Ok thanks, I was able to achieve even better performance than mplayer even though I still cannot make such a smooth playback as mplayer.
Well, I hope one day some guy come in and will make it happen... Smile
