* lavf/mpegts: add reading of ARIB data coding descriptorJan Ekström2019-02-10
| | | | | | | | | 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.
* add libaribb24 ARIB STD-B24 caption decoderJan Ekström2019-02-10
| | | | | | | | | | | | | | | | | | | | | | | | * Outputs ASS lines with basic coloring and font scaling for each given region. * Sets the default style to the resolution of the subtitle plane (for example, 960x540 / 36pt font for profile A). * Has options to: * Disable ruby text (which is coded as regions which have half-height text in libaribb24). Enabled by default as without positioning ruby text only confuses as it is usually coded in the beginning of the decoded subtitle line. * Set the working directory, in which libaribb24 will read configuration as well as into which it may save broadcast extra symbols as PNG. Unset by default. The unconventional library check can be explained by the library's current master branch being licensed as LGPLv3, but at the time of writing the latest official release is still licensed under GPLv3. Thus, one either has to wait for the following release, or enable GPLv3.

* avformat/mov: validate chunk_count vs stsc_datachcunningham2019-02-08
| | | | | | | | | | 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>
* avformat/mov.c: require tfhd to begin parsing trunchcunningham2019-02-08
| | | | | | | | | | 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().

| | | | | | | | | | 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.
