[Asterisk-video] app_mp4 problems

[Sergio Garcia]

Hi Klaus,

Could you send me the files to see what could be going wrong?
And personally, I use Helix Mobile Producer for encoding, Quick Time is horrible,
and ffmpeg has problems with cbr videos (and you have to enable amr manually).
You could also try the tmn h263 encoder, I haven't tried it myself, but ratmin sent
me an encoded video and the quality was quite good.

Best regards
