* 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: switch to AVStream.time_base as the hint for the muxer timebaseAnton Khirnov2014-06-18
| | | | | | | | | | | | Previously, AVStream.codec.time_base was used for that purpose, which was quite confusing for the callers. This change also opens the path for removing AVStream.codec. The change in the lavf-mkv test is due to the native timebase (1/1000) being used instead of the default one (1/90000), so the packets are now sent to the crc muxer in the same order in which they are demuxed (previously some of them got reordered because of inexact timestamp conversion).
* riffenc: take an AVStream instead of an AVCodecContextAnton Khirnov2014-06-18
| | | | | | It will be useful in the following commits. Also, rename the AVCodecContext pointer name from 'stream' to 'codec'.
* avienc: sanitize variable naming in write_header()Anton Khirnov2014-05-18
| | | | | | Do not call an AVCodecContext 'stream', that is highly confusing. Also, add a local variable for the current AVStream in the loop over all streams.

* avienc: drop the vfr flag.Anton Khirnov2013-11-08
| | | | | AVI does not really support vfr properly, only by padding with null packets.
* lavf: Reset the entry count and allocation size variables on av_reallocp ↵Martin Storsjö2013-09-26
| | | | | | | | | | | | | | failures When av_reallocp fails, the associated variables that keep track of the number of elements in the array (and in some cases, the separate number of allocated elements) need to be reset. Not all of these might technically be needed, but it's better to reset them if in doubt, to make sure variables don't end up conflicting. Signed-off-by: Martin Storsjö <martin@martin.st>

* 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>

* lavf: flush the output AVIOContext in av_write_trailer().Anton Khirnov2012-09-15
| | | | | | | This is consistent with stdio and is what we want to do in all cases. Fixes a bug in the voc muxer which didn't flush in write_trailer() previously. This is the cause of the change in the test results.
