* lavc: add a dummy field to AVStream to preserve ABI compatibility for avconvAnton Khirnov2013-10-29
| | | | | | | | avconv abuses the API by accessing AVStream.parser (which is private). Removing AVStream.reference_dts in 2ba68dd044ca8fc591139c05563840f546a9c0c0 breaks ABI compatibility for an old avconv using a newer lavf. Fix this by adding a dummy field until the next bump.

* lavf: Add a flag to enable/disable per-packet flushingLuca Barbato2013-09-16
| | | | | | | | | This is enabled by default and can be disabled with "-fflags -flush_packets". Inspired by a patch from Nicolas George <nicolas.george@normalesup.org>. Signed-off-by: Martin Storsjö <martin@martin.st>
* matroskaenc: Allow chapters to be written in trailerJohn Stebbins2013-09-04
| | | | | | | | This allows creation of frame accurate chapter marks from sources like DVD and BD where the precise chapter location is not known until the chapter mark has been reached during reading. Signed-off-by: Anton Khirnov <anton@khirnov.net>

|
* lavf: deprecate r_frame_rate.Anton Khirnov2012-07-29
| | | | | | | | | | | | | | | | | | | | According to its description, it is supposed to be the LCM of all the frame durations. The usability of such a thing is vanishingly small, especially since we cannot determine it with any amount of reliability. Therefore get rid of it after the next bump. Replace it with the average framerate where it makes sense. FATE results for the wtv and xmv demux tests change. In the wtv case this is caused by the file being corrupted (or possibly badly cut) and containing invalid timestamps. This results in lavf estimating the framerate wrong and making up wrong frame durations. In the xmv case the file contains pts jumps, so again the estimated framerate is far from anything sane and lavf again makes up different frame durations. In some other tests lavf starts making up frame durations from different frame.
* lavf: use dts difference instead of AVPacket.duration in find_stream_info()Anton Khirnov2012-07-29
| | | | | | | | | | AVPacket.duration is mostly made up and thus completely useless, this is especially true for video streams. Therefore use dts difference for framerate estimation and the max_analyze_duration check. The asyncts test now needs -analyzeduration, because the default is 5 seconds and the audio stream in the sample appears at ~10 seconds.
* avf: introduce nobuffer optionLuca Barbato2012-07-29
| | | | | | | | | | | | | Useful in cases where a significant analyzeduration is still needed, while minimizing buffering before output. An example is processing low-latency streams where all media types won't necessarily come in if the analyzeduration is small.

* make av_interleaved_write_frame() flush packets when pkt is NULLJindrich Makovicka2012-03-27

* lavf: make av_interleave_packet_per_dts() private.Anton Khirnov2012-03-20
| | | | | There is no reason for it to be public, it's only meant to be used internally.
* lavf: deprecate av_read_packet().Anton Khirnov2012-03-20
| | | | | | The caller can achieve the same effect (i.e. getting raw unparsed/mangled packets) with av_read_frame() and AVFMT_FLAG_NOPARSE | AVFMT_FLAG_NOFILLIN
* avformat: do not require a pixel/sample format if there is no decoderJustin Ruggles2012-03-05
| | | | | | | | Also, do not keep trying to find and open a decoder in try_decode_frame() if we already tried and failed once. Fixes always searching until max_analyze_duration in avformat_find_stream_info() when demuxing codecs without a decoder.
* lavf: deobfuscate read_frame_internal().Anton Khirnov2012-03-05
| | | | | | | | | | | | | | Split off packet parsing into a separate function. Parse full packets at once and store them in a queue, eliminating the need for tracking parsing state in AVStream. The horrible unreadable loop in read_frame_internal() now isn't weirdly ordered and doesn't contain evil gotos, so it should be much easier to understand. compute_pkt_fields() now invents slightly different timestamps for two raw vc1 tests, due to has_b_frames being set a bit later. They shouldn't be more wrong (or right) than previous ones.

| | | | | | | Put all private fields at the end and mark them as such so they can be easily changed/removed. This breaks ABI.
