I have configured, compiled a ffmpeg source code version 0.5 with versions as below:

FFmpeg version 0.5, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-memalign-hack libavutil 49.15. 0 / 49.15. 0 libavcodec 52.20. 0 / 52.20. 0 libavformat 52.31. 0 / 52.31. 0 libavdevice 52. 1. 0 / 52. 1. 0 on a linux host.

When i try to encode a raw yuv video using this version using theora codec by giving options as :

ffmpeg -f rawvideo -pix_fmt yuv420p -s 352x288 -r 30 -i foreman_352_x280_420.yuv -an -vcodec libtheora theora1.ogg

It gives an error: Unknown encoder 'libtheora'

But when i use the same command in a ffmpeg windows executable ( whose version is FFmpeg version SVN-r12665) it encoded to a theora video properly.

1) Doesnt ffmpeg version 0.5 on linux support theora encoder?

2)Which version for linux setup,would support theora encoding?

Maybe you just need to install (compile) libtheora for your linux distribution from . It might be that the windows distribution you used has it bundled, while the linux one does not.

Yep. On my Mac, running ffmpeg comes up with --enable-libtheora in the configure options, among other things. – fideli Feb 5 '10 at 17:30
