[Asterisk-video] app_mp4 -- need help

[Sergio García Murillo]

Try allowing only h263, appart of that depending on the codecs, the resulting mp4 is very probably that isn't 3gpp compliant, so
many players would have difficulties playing it, using h263 and pcmu i was able to play it with vlc but the sound didn't work.
Nevertheless i think that using mp4 for audio/video files would be a much better solution for media files as you can have any
encoded stream and even having the same track encoded in different codecs/bitrates.

	I don't perform any transcoding, just dump the encoded streams to the mp4 so they *should* be as good as the original.
	Which codecs are u using? Have you tried to play the mp4 with a media player?

	Hi
	
	The quality of the recorded mp4 is not so good, maybe it is because of the video codecs.
	Other than that, everything works fine, thank you sergio :). 
	I am using asterisk-1.2.13
