The Nokia documentation isn't completely clear on what's supported and what not on S60.2 and S60.3.
Is h263+ (aka h263v2/h263 1998) in 3gp supported? My testing on N95 suggests it is not, but maybe the problem is with the container format (I had some trouble muxing with ffmpeg and mp4box).
The docs say "MPEG4 Visual" is supported, so I think I'll go with that. But what exactly is supported? What Xvid settings can and cannot be used? What resolutions, framerates, bitrates, etc.?
If using MP4 container and Xvid video (MPEG4 SP/ASP), I assume AAC LC would be fine?
Are there any special considerations when muxing to 3gp/mp4 with mp4box or ffmpeg?
