* 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.
* dvenc: Validate the frame size before copying itLuca Barbato2015-11-28

* lavc: export DV profile API used by muxer/demuxer as publicAnton Khirnov2014-07-09
|
* dv: Split DV data table declarations into their own headerDiego Biurrun2013-11-15
| | | | | | This is necessary to avoid target config settings bleeding into the host compilation process with hardcoded tables and the DV VLC tables no longer present as static tables in a header file.
* lavf: Don't explicitly flush after each written packet in muxersClément Bœsch2013-09-16
| | | | | | | | Since 596e5d4783, this is not necessary anymore. It also allows to actually disable the flushing, improving write performance (but possibly giving worse latency in real-time streaming). Signed-off-by: Martin Storsjö <martin@martin.st>

* dv: Split profile handling code into a separate file.Diego Biurrun2012-05-07

* 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: remove disabled FF_API_TIMESTAMP cruftAnton Khirnov2012-01-27

* lavc: use avpriv_ prefix for some dv symbols used in lavf.Anton Khirnov2011-10-20
| | | | Specifically, ff_dv_frame_profile and ff_dv_codec_profile.
* fifo: add av_fifo_peek2(), and deprecate av_fifo_peek()Stefano Sabatini2011-08-26
| | | | | | | The new function provides a more generic interface than av_fifo_peek() for peeking at a FIFO buffer data. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavf: use designated initialisers for all (de)muxers.Anton Khirnov2011-07-17
| | | | It's more readable and less prone to breakage.
* lavf: factor out conversion of ISO8601 string to unix timeAnton Khirnov2011-07-13
|
* lavf: deprecate AVFormatContext.timestampAnton Khirnov2011-07-12
| | | | It's replaced by 'creation_time' metadata tag.

* 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.
* Make dvenc.c functions static to the unit.Diego Elio Pettenò2011-01-25
| | | | | | | Also drop some CONFIG_DV_MUXER #ifdefs probably vestigial from before the split of dvenc and dvdec. Signed-off-by: Mans Rullgard <mans@mansr.com>
