* 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.

* vocdec: do not create the stream in read_header()Anton Khirnov2015-12-12
| | | | | The stream parameters are not known until we read a packet, so postpone creating it until then.

* vocdec: Don't update codec parameters mid-streamMartin Storsjö2013-09-16
| | | | | | | | | | | | | | | | | | If we really want to support parameter changes, they need to be signalled along with the AVPackets as parameter change side data, not just changing the AVCodecContext parameters when a packet is demuxed (since there may be other earlier packets yet undecoded). Something similar was already done for the sample rate in 0883109b2, but some parameters were left changeable. This avoids having to recheck the channel count for validity for each decoded frame in (ad)pcm decoders, unless the decoders explicitly say that they accept parameter changes.

* cosmetics: Align muxer/demuxer declarationsMartin Storsjö2012-04-06
| | | | | | | Also add missing trailing commas, break long codec_tag lines and add spaces in codec_tag declarations. Signed-off-by: Martin Storsjö <martin@martin.st>
* voc/avs: Do not change the sample rate mid-stream.Justin Ruggles2012-03-03
| | | | | Also, set the time base based on the sample rate. lavf-voc seek test updated to reflect slightly different seek points.
* 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>

| | | | | 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.

| | | | Use it instead of url_is_streamed and AVIOContext.is_streamed.
