Description (last modified by nanang)
- generation of SDP
- how codec can put codec specific info in SDP?
- codec specific SDP negotiation, if any
- applying parameters in SDP to the codec
TODO:
- add video SDP generation in pjmedia_endpt_create_sdp()
- add video stream info generation from SDP in pjmedia_stream_info_from_sdp()
- add codec specific negotiation, perhaps sdp_neg.c should have external format negotiation mechanism to handle format specific negotiation, e.g: H26x picture resolution negotiation, this negotiation result will be applied to codec param (for stream in opening the codec)
- add auto-assignment mechanism for dynamic payload type (in endpoint when creating SDP?), currently, the space for hardcoded dynamic payload type is very tight (or even not enough for video formats)
- auto apply (or at least validate) SDP fmtp setting to codec param (or the other way around?), e.g: when SDP fmtp setting in codec is set to "CIF=1" codec param should be set to "size=352x288 & fps=30/1.001"
- add video capability to simpleua to test video stuffs on real SIP application

- Added custom negotiation callback mechanism in SDP negotiator, mainly for specific formats that require SDP fmtp negotiation.
- Modified video codec ID string to use encoding name+payload type (was encoding name+clock rate), also added encoding description in video codec info, so duplicated codecs (e.g: multiple H264 configurations) can be differentiated.
- Few enhancements for H264 in ffmpeg wrapper (e.g: added proper profile-id & packetization-mode setup).
