* | lavf/utils: simplify matching MOV-like formatsClément Bœsch2016-09-141-3/+1

* | lavf: add avformat_transfer_internal_stream_timing_info() and use it in ffmpegClément Bœsch2016-09-141-0/+64
| | | | | | | | | | In lavf we have access to st->internal->avctx so it's a better place than in ffmpeg*.c and will allow moving to codecpar.
* | avformat: Export ticks_per_frame in st->codecMichael Niedermayer2016-09-071-1/+3
| | | | | | | | | | | | | | | | | | | | Fixes regressions with stream copy and output timebase/fps being twice as fine as needed Makes the timebase and ticks per frame handled identical which should make the code easier to understand and work with. It does not solve the problem without st->codec access Suggested-by: Hendrik Leppkes Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* | avformat/utils: Fix find_stream_info not considering the extradata it foundAnssi Hannula2016-07-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9200514ad8717c6 ("lavf: replace AVStream.codec with AVStream.codecpar") merged in commit 6f69f7a8bf6a0d01 changed avformat_find_stream_info() to put the extradata it got from st->parser->parser->split() to st->internal->avctx instead of st->codec (extradata in st->internal->avctx will be later copied to st->codecpar). However, in the same function, the "is stream ready?" check was changed to check for extradata in st->codecpar instead of st->codec, even though st->codecpar is not yet updated at that point. Extradata retrieved from split() is therefore not considered anymore, and avformat_find_stream_info() will therefore needlessly continue probing in some cases. Fix that by checking for the extradata at st->internal->avctx where it is actually put.

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-231-91/+232
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
