[asterisk-users] I think this is a bug (video call file) 11.25.1 and 13.13.1

Hi Mark,

Thanks for your reply...
I just tried what you suggested on only got audio. I created a wav file and
put it in the /tmp
directory just like the video.h264 file. So /tmp has video.h264 and
video.wav both.
I then placed the call and only heard the audio from the wav file.

I used this for my call file:
Channel: SIP/2002
Context: testing
Extension: 999999
Priority: 1
Application: Playback
Codecs: h263,h264,vp8,g722,ulaw,alaw,wav
Data: /tmp/video

My Bria 4 softphone uses the h263 and h264 codecs and of course wav file
Based on your look of the code did I miss something to trigger the playing
of the video file?
I can extract the audio out to a seperate file - so not a show stopper for

No errors showed up on the Asterisk CLI when I did my test.

Thanks so much,
