Those errors are normal, run mp4info video.mp4 to see if it has created both
tracks correctly.

Also those traces are correct, except that I see 2 hint tracks for the same
video track.

Remove the log files in /tmp and run it again.
It should create a media_out_XXX.raw file for output video stream if
everything is correct,
rename it to .h263 and play it with vlc to see if it's correct.
If everything is fine thenh263 stream is been sent correctly to the handset
so it's not correctly
encoded yet.
