* lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.
* rtp: Initial H.261 supportThomas Volkert2014-12-18
| | | | | | | | | | | | | | The packetizer only supports splitting at GOB headers - if such aren't available frequently enough, it splits at any random byte offset (not at a macroblock boundary either, which would be allowed by the spec) and sends a payload header pretend that it starts with a GOB header. As long as a receiver doesn't try to handle such cases cleverly but just drops broken frames, this shouldn't matter too much in practice. Signed-off-by: Martin Storsjö <martin@martin.st>

* sdp: Simplify parsing/conversion of H264 extradataMartin Storsjö2014-10-06
| | | | | | | | | | | | By using ff_avc_write_annexb_extradata instead of the h264_mp4toannexb BSF, the code for doing the conversion itself is kept much shorter, there's less state to restore at the end, we don't risk leaving the AVCodecContext in an inconsistent state if returning early due to errors, etc. Also add a missing free if the base64 encoding fails.

* rtpenc: Allow requesting H264 RTP packetization mode 0Martin Storsjö2012-06-18
| | | | | | | | | This requires all NAL units to fit within single RTP packets. It doesn't change the actual packetization for packets that fit, but errors out and gives a helpful hint if the NAL units would have to be split, and signals the right packetization mode in the SDP. Signed-off-by: Martin Storsjö <martin@martin.st>
* Replace memset(0) by zero initializations.Diego Biurrun2012-03-28
| | | | Also remove one pointless zero initialization in rangecoder.c.
* rtpenc: Allow packetizing H263 according to the old RFC 2190Martin Storsjö2012-02-23
| | | | | | | | | | | | | | | | | | According to newer RFCs, this packetization scheme should only be used for interfacing with legacy systems. Implementing this packetization mode properly requires parsing the full H263 bitstream to find macroblock boundaries (and knowing their macroblock and gob numbers and motion vector predictors). This implementation tries to look for GOB headers (which can be inserted by using -ps <small number>), but if the GOBs aren't small enough to fit into the MTU, the packetizer blindly splits packets at any offset and claims it to be a GOB boundary (by using Mode A from the RFC). While not correct, this seems to work with some receivers. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | If the sdp is generated before the rtp muxer is initialized (e.g. as when called from the rtsp muxer), this has to be done, otherwise the rtp muxer doesn't know that the input really is in mp4 format. Signed-off-by: Martin Storsjö <martin@martin.st>
