2019-02-10avformat/hlsenc: fix fmp4_init_filename file name with %v problemSteven Liu
when set option fmp4_init_filename to init_%v.mp4 before patch: the init file will be init_%v_0.mp4, init_%v_1.mp4 after patch: the init file will be init_0.mp4, init_1.mp4 Reported-By: Gyan Doshi <ffmpeg@gyani.pro> Signed-off-by: Steven Liu <lq@chinaffmpeg.org>
2019-02-10lavf/mpegts: add reading of ARIB data coding descriptorJan Ekström
This enables us to read the data coding type utilized for a specific private data stream, of which we currently are interested in ARIB caption streams. The component tag limitations are according to ARIB TR-B14, and the component IDs are defined in ARIB STD-B10.
2019-02-09lavf/mpegts: Convert service_name and service_provider to utf-8.Carl Eugen Hoyos
Fixes ticket #6320.
2019-02-08avformat/mov: validate chunk_count vs stsc_datachcunningham
Bad content may contain stsc boxes with a first_chunk index that exceeds stco.entries (chunk_count). This ammends the existing check to include cases where chunk_count == 0. It also patches up the case when stsc refers to unknown chunks, but stts has no samples (so we can simply ignore stsc). Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2019-02-08avformat/mov.c: require tfhd to begin parsing trunchcunningham
Detecting missing tfhd avoids re-using tfhd track info from the previous moof. For files with multiple tracks, this may make a mess of the avindex and fragindex, which can later trigger av_assert0 in mov_read_trun().

2019-02-07avformat/movenc: Add more error checking when writing sample entries.Nikolas Bowe
Fixes a problem where a sample entry which cannot be written correctly appears to succeed, but produces an invalid file. For example, this command: ffmpeg -f lavfi -i sine=frequency=1000:duration=5 -codec:a ac3 -movflags +empty_moov -frag_duration 5000000 /tmp/foo.mp4 produced a file with the ac-3 sample entry, but no AC3SpecificBox (dac3) child, which is invalid according to ETSI TS 102 366.

2019-01-22avformat/concatdec: always re-calculate start time and durationMarton Balint
This allows the underlying files to change their duration on subsequent avformat context opens. An example use case where this matters: ffconcat version 1.0 file dummy.mxf file dummy.mxf ffmpeg -re -stream_loop -1 -i dummy.ffconcat -f sdl2 none The user can seamlessly change the input by atomically replacing dummy.mxf. v2: Set ConcatFile duration in read_header for all segments with known durations because from now on we always recalculate the start time in open_file, and an instant seek could have caused unset ConcatFile durations.

2019-01-02mov: Remove duration-of-last-frame heuristic hackDerek Buitenhuis
This breaks totally valid files that get caught in its heuristic. This, according to the commit message, is my own doing, having asked Michael to implement this check and providing a sample that was "wrong". I am now atoning for my sins, and removing this hack, having seen the light (aka that this was silly to do in the first place). Resotores correct behavior on valid files.
