Hi!
I'm trying to convert an .avi file to a .mp4 file with H.264. When I'm trying to do this I get an error saying "Unknown encoder H.264." What do I need?
I'm using WinFF for the task. I think it uses ffmpeg, but I can't find out how I can make it support the H.264 codec. Anyone?

you need to go to menu edit - presets and change the h.264 settings. change -vcodec h264 to -vcodec libx264 and -acodec aac to -acodec libfaac

Thanks, I will try that! But will those settings still allow me to play the converted file on my PS3?

if it can play mp4 videos it will. those changes dont do anything just let ffmpeg find the codecs, but converting from avi will probably make pretty crappy quality.

I see. thanks again!
No, the difference in quality is not that big. I've done it before...

You all may want to check to see if you're actually producing aac audio with FAAC. Honestly, it's been broken in Arch for months, the solution is known, and it's not being implemented. If you see the last line after faac --help, you're producing mp2 audio:
