[jitsi-users] Video call with iphone bria ( using 1.1-nightly.build.4116)


#1

Hi

     I am trying to use 1.1-nightly.build.4116 to make a video call with bria on iPhone.

     (1) It seems jitsi only send baseline profile or main profile in sdp depending on the configure in Options->Advanced->H.264

       question is: why not send both baseline profile and main profile in sdp as Jitsi already support both profiles?

    (2) the bria currently only support baseline profile,
         so I set jitsi to use baseline profile. then make a call to bria.

          however jitsi send sdp ( for video):

                      Media Attribute (a): fmtp:97 profile-level-id=42901f

         but bria reply with:

                     Media Attribute (a): fmtp:97 profile-level-id=42E00b

         the difference ( 0b or 1f) seems to be: level_idc , does it matter?

          From the trace, in this case jitsi does NOT send out video stream. while bria do send out video stream.

          why?

Thanks
