* avformat: Avoid allocation for AVStreamInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | Do this by allocating AVStream together with the data that is currently in AVStreamInternal; or rather: Put AVStream at the beginning of a new structure called FFStream (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVStreamInternal altogether.

* avformat/rawdec: Deduplicate AVClasses based upon ff_raw_optionsAndreas Rheinhardt2021-07-08
| | | | | | | | The child_class_next API relied on different (de)muxers to use different AVClasses; yet this API has been replaced by child_class_iterate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/flacdec, takdec: Use FFRawDemuxerContext directlyAndreas Rheinhardt2021-07-08
| | | | | | | | | | | | | The beginning of the private contexts of both the FLAC and the TAK demuxer currently mimick FFRawDemuxerContext: A pointer to an AVClass followed by the AVOpt-enabled field raw_packet_size. Said field is only used by the demuxers' read_packet functions via ff_raw_read_partial_packet(), which treats the private context as an FFRaawDemuxerContext. Yet this is fragile, so better include a FFRawDemuxerContext struct at the beginning of said demuxers' private contexts. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/rawdec: Make the raw packet size configurableMichael Niedermayer2019-07-17
| | | | | | | | This allows testing parsers with a wider range of input packet sizes. Which is important and usefull for regression testing, some of our parsers in fact to not work if the packet size is changed from 1024 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

|\ | | | | | | | | | | | | * commit '83548fe894cdb455cc127f754d09905b6d23c173': lavf: fix usage of AVIOContext.seekable Merged-by: James Almer <jamrial@gmail.com>
| * lavf: fix usage of AVIOContext.seekableAnton Khirnov2016-09-30
| | | | | | | | | | | | | | | | It is supposed to be a flag. The only currently defined value is AVIO_SEEKABLE_NORMAL, but other ones may be added in the future. However all the current lavf code treats this field as a bool (mainly for historical reasons). Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.

| | | | | | | | | | | | | | This avoids the danger that get_bits.h might get indirectly #included before BITSTREAM_READER_LE is defined. Also sort headers into canonical order where appropriate.

| * 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.
