* 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.

* lavf: remove AVFormatParameters from AVFormatContext.read_header signatureAnton Khirnov2012-01-27

* lavf: make av_set_pts_info private.Anton Khirnov2011-11-30
| | | | It's supposed to be called only from (de)muxers.
* avcodec: add support for planar signed 8-bit PCM.Justin Ruggles2011-11-09
| | | | | | It is found in some 8svx files (e.g. ones created by SoX). Currently the decoder reuses the 8svx functions because we already have handling of a single large planar packet for the compressed 8svx codecs.
* lavf,lavd: replace av_new_stream->avformat_new_stream part I.Anton Khirnov2011-10-19
| | | | | Trivial replacements with sed are done in this commit: sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'
* 8svx/iff: fix decoding of compressed stereo 8svx files.Justin Ruggles2011-09-22
| | | | | | | | | | Make the iff demuxer send the whole audio chunk to the decoder as a single packet and move stereo interleaving from the iff demuxer to the decoder. Based on a patch by Stefano Sabatini. git.videolan.org/ffmpeg.git commit e280a4da2ae6fd44f0079358ecc5aa08e388a5ed

| | | | | | | | | | | | | | In the name of consistency: get_byte -> avio_r8 get_<type> -> avio_r<type> get_buffer -> avio_read get_partial_buffer will be made private later get_strz is left out becase I want to change it later to return something useful.

* 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 ff_cmap_read_palette static to libavcodec/iff.c. Delete iff.h.Diego Elio Pettenò2011-01-26
| | | | | | | | The iff.h header only declared one function that is now static, the libavformat/iff.c source file wasn't using it before. Drop the file entirely. Signed-off-by: Mans Rullgard <mans@mansr.com>
