* 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.
* pcmdec: replace a reachable assert with an error checkAnton Khirnov2014-02-10
| | | | | | Libavformat should not make any assumptions about values returned from other libraries. This assert is easily reachable by using a non-raw codec id.
* pcm: change references to raw to pcmLuca Barbato2012-10-25
|
* pcmdec: change default of channels parameter to 1Janne Grunau2012-10-25
| | | | | This was previously implicitly done in ff_raw_read_header(). Fixes fate tests with pcm input.
* pcmdec: remove dependency from rawdecLuca Barbato2012-10-25
| | | | The code shared is not actually shared with anything else.
* avopt: Store defaults for AV_OPT_TYPE_INT in the i64 union memberMartin Storsjö2012-09-04

* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-07

* avformat: Drop pointless "format" from container long namesDiego Biurrun2012-07-30

* libavformat: Add an ff_ prefix to some lavf internal symbolsMartin Storsjö2012-02-15
| | | | | | | | | | Prefix the functions/tables brktimegm, pcm_read_seek, dv_offset_reset, voc_get_packet, codec_movaudio_tags, codec_movvideo_tags. After this, lavf has no global symbols without the proper prefix. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavf: rename AVInputFormat.value to raw_codec_id.Anton Khirnov2012-01-31
| | | | It's only used by raw demuxers for storing the codec id.
* AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_*Anton Khirnov2011-10-12
|
* Use explicit struct initializers for AVOutputFormat/AVInputFormat declarations.Diego Biurrun2011-09-24
|
* pcmdec: use unique classes for all pcm demuxers.Anton Khirnov2011-09-17
|
* rawdec: add sample_rate/channels private options.Anton Khirnov2011-05-25
|
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.Diego Elio Pettenò2011-01-26
| | | | | 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.
* split raw.c into rawdec.c and rawenc.cAurelien Jacobs2010-08-30

* move pcm demuxers to their own fileAurelien Jacobs2010-08-30
