[asterisk-users] How to set video native format for asterisk

[Sharan Saxena]

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).
