Dear List Members,
I am trying to play a .h263 video file. I changed my
DialPlan to get some values:
exten=> 600,n,NoOp(${CHANNEL(audionativeformat)}) ; gives alaw
exten=> 600,n,NoOp(${CHANNEL(audioreadformat)}) ; alaw
exten=> 600,n,NoOp(${CHANNEL(audiowriteformat)}) ; alaw
exten=> 600,n,NoOp(${CHANNEL(videonativeformat)}) ;
unknown. H263 is 524288 (1<<19).
>From documentation, I see that videonativeformat is a read-only field, and
thus we are unable to set. While debugging the code, I see a mismatch
between the channel native format and the existing format for videos which
asterisk has. My channel native format value is 8, which I think corresponds
to the case of alaw (1<<3).
I do a "sip show settings" and note that:
Videosupport = Yes
Codec Order: g722:20, g723:30,alaw:20,ulaw:20
The audio file which I have plays, but the video file [.h263] fails to play.
I am using a Bria Soft Phone, and my Linux OS is CentOs 5 configured as a
Virtual Machine on Windows Vista.
Welcoming your suggestions and help,
Regards
Sharan
