Hey, most stuff seems to work fine; 1080p h264 stuff plays perfectly smoothly, though some 720 ffmpeg stuff is quite stuttery.

http://pastebin.com/teJdWjvP has my debug log, from starting xbmc to trying to play.

It's these bits I'm concerned by;

Does that mean that the ATV doesn't have hardware to decode ffmpeg video ? Should I re-encode this sort of video ?

I don't think anyone know if ffmpeg can be decoded on the GPU yet. The developers are discovering what's possible and what isn't as they go.

I usually see certain flavor of ffmpeg causes the CPU to go to 100%, and that is the cause for the stuttery playback. We need to find a way to have the GPU properly decode that codec.

If you search for the keymap thread, you'll see a way to map the codecinfo OSD to a button on the remote so you can more easily see all the relevant info related to playing that file.

That's the problem, the decoder can't read the data quick enough.

Cool, thanks. Sounds like the Cunning Idea is to reencode high bitrate stuff as H264 then.
