[Asterisk-video] app_mp4 -- need help

[Sergio García Murillo]

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
