we've been trying to get Wengophone 2.1 video calls working with a grandstream video phone utilizing H.263/G.711a. symptoms were that video/audio from the grandstream is displayed fine and sounds great on wengophone, but there is no video displayed on the grandstream and while audio is fine, there's a high-pitched whine on the line.
poring through the wengophone code, in wifo/phapi/phcodec.c, there's a hack with a comment which says, // HACK: Define H263 codec in SDP but use h263p encoder and decoder (a trick to bypass cirpack). TO remove the hack, just use these uncommented lines to replace the definition of h263_codec doing what the comment says fixes the video issue, i.e. video is displayed correctly on the grandstream, though the audio whine still remains. my questions are 1. has any one faced this audio whine before and what's causing it ? 2. what was the reasoning behind the cirpack HACK and if this can be removed since it would obviously stop interoperablity between wengophone and any other phone which relies on H.263 for the video codec. if its all ok, i'll submit a patch which hopefully can be included into the subversion repo. -- Regards, /\_/\ "All dogs go to heaven."
