* 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.
* mxfenc: always assume long gopAnton Khirnov2015-12-06
| | | | | | Checking the codec context parameters to find out this information is far too unreliable to be useful, so it is safer to assume B-frames are always present.
* avpacket: Replace av_free_packet with av_packet_unrefLuca Barbato2015-10-26
| | | | | | | `av_packet_unref` matches the AVFrame ref-counted API and can be used as a drop in replacement. Deprecate `av_free_packet`.
* Replace av_dlog with normal av_log at trace levelVittorio Giovara2015-04-19
| | | | This applies to every library where performance is not critical.

* lavf: move internal fields from public to internal contextwm42015-02-10
| | | | | | | This is not an API change; the fields were explicitly declared private before. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* Use gmtime_r instead of gmtime and localtime_r instead of localtimeMartin Storsjö2014-10-26
| | | | | | | | | | | gmtime isn't thread safe in general. In msvcrt (which lacks gmtime_r), the buffer used by gmtime is thread specific though. One call to localtime is left in avconv_opt.c, where thread safety shouldn't matter (instead of making avconv depend on the libavutil internal header).

* mxfenc: Fix possible integer overflowsTomas Härdin2014-10-24
| | | | | | | | | None of these are likely unless the user is writing a file with two billion streams or a duration of around two months. CC: libav-stable@libav.org Bug-Id: CID 700568 / CID 700569 / CID 700570 / CID 700571 / CID 700572 / CID 700573
* 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).
* lavf: add AVFMT_FLAG_BITEXACT.Anton Khirnov2014-05-15
| | | | | | | | Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's codec context. Using codec options inside lavf is fragile and can easily break when the muxing codec context is not the encoding context.

* 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.
