[mov,mp4,m4a,3gp,3g2,mj2 @ 0x10100e800] Unimplemented container channel layout.
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x10100e800] If you want to help, upload a sample of this file to ftp://upload.ffmpeg.org/MPlayer/incoming/ and contact the ffmpeg-devel mailing list.

Seems stream 0 codec frame rate differs from container frame rate: 30000.00 (30000/1) -> 29.97 (30000/1001)

Incompatible pixel format 'yuv422p10le' for codec 'mpeg4', auto-selecting format 'yuv420p'
encoder 'aac' is experimental and might produce bad results.
Add '-strict experimental' if you want to use it.
