Anton Khirnov	8b64c2ba03	lavc: add a dummy field to AVStream to preserve ABI compatibility for avconv avconv abuses the API by accessing AVStream.parser (which is private). Removing AVStream.reference_dts in `2ba68dd044` breaks ABI compatibility for an old avconv using a newer lavf. Fix this by adding a dummy field until the next bump.	11 years ago
Anton Khirnov	2ba68dd044	lavf: remove unreliable timestamp guessing heuristic	11 years ago
Luca Barbato	596e5d4783	lavf: Add a flag to enable/disable per-packet flushing 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>	11 years ago
John Stebbins	26b241c079	matroskaenc: Allow chapters to be written in trailer 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.

Luca Barbato	c2cb01d418	lavf: introduce AVFMT_TS_NEGATIVE Most formats do not support negative timestamps, shift them to avoid unexpected behaviour and a number of bad crashes.

Anton Khirnov	1afddbe59e	avpacket: use AVBuffer to allow refcounting the packets. This will allow us to avoid copying the packets in many cases. This breaks ABI.	12 years ago

Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Anton Khirnov	aba232cfa9	lavf: deprecate r_frame_rate. 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.	12 years ago
Anton Khirnov	fe1c1198e6	lavf: use dts difference instead of AVPacket.duration in find_stream_info() 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.	12 years ago
Luca Barbato	681ed00099	avf: introduce nobuffer option 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.

Anton Khirnov	a6733202cc	lavf: make av_interleave_packet_per_dts() private. There is no reason for it to be public, it's only meant to be used internally.	13 years ago
Anton Khirnov	3c90cc2ef2	lavf: deprecate av_read_packet(). 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	13 years ago
Justin Ruggles	8c1d6ac66a	avformat: do not require a pixel/sample format if there is no decoder 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.	13 years ago
Anton Khirnov	27c7ca9c12	lavf: deobfuscate read_frame_internal(). 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.	13 years ago
