Paul B Mahol	323b8c95e4	avformat: add AVFormatContext to ff_get_extradata() Needed for av_log() inside that function. Signed-off-by: Paul B Mahol <onemda@gmail.com>	9 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
Luca Barbato	ce70f28a17	avpacket: Replace av_free_packet with av_packet_unref `av_packet_unref` matches the AVFrame ref-counted API and can be used as a drop in replacement. Deprecate `av_free_packet`.	9 years ago

Justin Ruggles	5d0450461f	idcin: better error handling Add some additional checks for EOF and print error messages on an incomplete header or packet. FATE reference updated for id-cin-video due to the demuxer no longer returning a partial video packet at EOF.	12 years ago
Justin Ruggles	06deaf8ad3	idcin: return 0 from idcin_read_packet() on success. This matches the AVInputFormat.read_packet() API.	12 years ago
Justin Ruggles	7040e479a1	idcin: allow seeking back to the first packet Also, do not allow seek-by-byte, as there is no way to find the next packet boundary.	12 years ago
Justin Ruggles	ccc0ffb1ba	idcin: set start_time and packet duration instead of manually tracking pts. Also, use 1 / sample_rate for audio stream time_base.	12 years ago

Justin Ruggles	33f58c3616	idcin: check for integer overflow when calling av_get_packet() chunk_size is unsigned 32-bit, but av_get_packet() takes a signed int as the packet size.	12 years ago

Diego Elio Pettenò	66355be3c3	Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. This also lists the objects from those two libraries as internal (by adding the ff_ prefix) so that they can then be hidden via linker scripts. (cherry picked from commit `c6610a216e`)	14 years ago
