* 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.

* bethsoftvid: synchronize video timestamps with audio sample rateJustin Ruggles2012-02-16
| | | | | | | | According to unofficial documentation, the video rate is locked to the audio sample rate. This results in proper synchronization of audio and video timestamps from the demuxer. This only works if the first audio packet occurs before the first video packet or the audio sample rate is the default rate of 11111 Hz, both of which are true for all samples in our archive.
* bethsoftvid: add audio stream only after getting the first audio packetJustin Ruggles2012-02-16
| | | | | | This avoids initializing a stream with dummy values or when the file does not contain audio. Also set duration for audio packets, using the sample rate as the time base.
* bethsoftvid: Set video packet duration instead of accumulating pts.Justin Ruggles2012-02-16

* bethsoftvid: set packet key frame flag for audio and I-frame video packets.Justin Ruggles2012-02-16
| | | | | Fixes avconv video stream copy of bethsoft video, which was skipping all video frames unless the copyinkf option was used.
* bethsoftvid: fix read_packet() return codes.Justin Ruggles2012-02-16
| | | | Use proper AVERROR codes, and return 0 for no error.
* bethsoftvid: pass palette in side data instead of in a separate packet.Justin Ruggles2012-02-16
| | | | | | Update FATE reference to account for now non-existent palette packet. This also fixes the FATE test if frame data is not initialized in get_buffer(), so update comment in avconv accordingly.

* lavf: make av_set_pts_info private.Anton Khirnov2011-11-30
| | | | It's supposed to be called only from (de)muxers.

| | | | | Trivial replacements with sed are done in this commit: sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'
* lavf: use designated initialisers for all (de)muxers.Anton Khirnov2011-07-17
| | | | It's more readable and less prone to breakage.

| | | | | | | These statements cannot be reached and are thus not needed. This removes a number of compiler warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | | | | | | | | | | | 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.
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
