Michael Niedermayer	f9d7431272	avformat/AVFormatContext: Move fields down to match the fork avconv uses private and internal fields from libavformat, we thus must match the layout even of the fields marked non public. Otherwise ffmpegs libavformat could not be used as a dropin replacement on debian/ubuntu The current soname of libavformat was not part of any release nor are any fields marked public moved thus in theory no installed shared lib ABI breakage should occur. Still the need for this change is unfortunate and chilling. If you installed shared libs from a recent development version of libavformat that is more recent than the last release. You probably want to check or rebuild applications that linked to it. minor versions of avformat & avdevice are bumped to allow detecting this as both use the updated struct Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Matthew Heaney	bc35df29c1	lavf: add AV_DISPOSITION flags for WebVTT text track kinds There are 4 separate WebVTT text track kinds: subtitles (the default if not otherwise specified), captions, descriptions, and metadata. The WebM muxer needs to know which WebVTT text track kind this is, in order to synthesize the correct track type and codec id. To allow a demuxer to indicate the text track kind of the input, a new set of AV_DISPOSITION flag values has been added, corresponding to each of the non-default text track kind values.	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.	13 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.	13 years ago
