Carl Eugen Hoyos	dc77e64f2d	lavf/rtpdec*: Constify all RTPDynamicProtocolHandler. Reviewed-by: Muhammad Faiz	7 years ago
Carl Eugen Hoyos	6969bed12c	lavf/rtpdec_g726: Map mime type G726 to g726le. Add new mime types AAL2-G726 for g726 as suggested in rfc 3551. This patch will break interaction with applications that incorrectly use big-endian G.726 with mime type G726 but we know of at least one device (DVTel camera) that correctly implements the rfc, so do the same. Fixes ticket #5890.	8 years ago
Anton Khirnov	9200514ad8	lavf: replace AVStream.codec with AVStream.codecpar 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.	9 years ago

Martin Storsjö	fa6dce4c57	rtpdec: Interpret the different G726 names as bits_per_coded_sample For the standardized 8 kHz sample rate, this works exactly the same. For nonstandard sample rates, the different predefined G726 names (G726-16, G726-24, G726-32, G726-40) are interpreted as an indication of the bits per coded sample, even though their actual bitrates aren't what the name specifies. This feels more sane than using free-form names for nonstandard sample rate/bitrate combinations, e.g like G726-22, G726-33 for 11025 Hz. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Miroslav Slugeň	06d7325ab1	rtpdec: Add support for G726 audio This requires using a separate init function, since there isn't necessarily any fmtp lines for this codec, so parse_sdp_a_line won't be called. Incorporating it with the alloc function wouldn't do either, since it is called before the full rtpmap line is parsed (where the sample rate is extracted).
