I try to set up a video call between a raspberry camera and a SIP terminal. The SDP offer from SIP terminal is: m=video 49224 RTP/AVP 122 123 34 a=rtpmap:122 H264/90000 a=fmtp:122 profile-level-id=64E00C;max-br=384 a=rtpmap:123 H264/90000 a=fmtp:123 profile-level-id=42E00C;max-br=384 a=fmtp:34 CIF=2 QCIF=2 MaxBR=2560 a=pri:HME,640*360,o,s3,s2 So I want to generate the H264 RTP stream with the right params. > I believe the profile level ID reflects certain encoding options and > should be set by the encoder to indicate them: > > http://stackoverflow.com/a/22970025/3974309 > > If you only know that number (where do you have it from?) and want to > encode for it, I am guessing that you will have to set the > corresponding encoder options: > > profile_idc = 0x42 => "-profile baseline" > profile-iop = 0xE0 => I have no idea how to set the constraints.
