[Asterisk-video] MP4 Application not working in 1.4.26

[Hemanshu Patel]

hi,
i was trying to tell you that you have to enable h264 from your sip.conf ,
then only i guess it will work, and also your phone (terminal equipment)
should support h264.
Because from the logs you have sent, it seems either you havent enable h264
or your phone either doesnt support or not given preference in codec
selection.

As far as playing those file in vlc is concerned, i think, asterisk add some
header information in video files, might be because of this it doenst play
in normal video players like vlc.
