* libavformat/dashenc: Reduce confusion in par error messageChris Miceli2020-08-31
| | | | | | | | | | In ticket #8754 there is discourse surrounding the error message which is printed upon a mismatched aspect ratio in derived encodings. This should make it clearer to the user as to the issues which they are experiencing.

* avformat/mov: See if mfra makes up the difference for an incomplete sidx.Dale Curtis2020-08-28
| | | | | | | | | | | | | A few popular sites have started generating MP4 files which have a sidx plus an mfra. The sidx accounts for all size except the mfra, so the old code did not mark the fragment index as complete. Instead we can just check if there's an mfra and if its size makes up the difference we can mark the index as complete.

* avformat/movenc: write the colr atom by defaultMichael Bradshaw2020-08-21
| | | | | | | | | | | | | | | | | The write_colr flag has been marked as experimental for over 5 years. It should be safe to enable its behavior by default as follows: - Write the colr atom by default for mp4/mov if any of the following: - The primaries/trc/matrix are all specified, OR - There is an ICC profile, OR - The user specified +write_colr - Keep the write_colr flag for situations where the user wants to write the colr atom even if the color info is unspecified (e.g., http://ffmpeg.org/pipermail/ffmpeg-devel/2020-March/259334.html) This fixes https://trac.ffmpeg.org/ticket/7961 Signed-off-by: Michael Bradshaw <mjbshaw@google.com>
* avformat/libsrt: close listen fd in listener modeNicolas Sugino2020-08-20

* avformat/mpegts: only reset timestamps to NOPTS for DVB teletextJan Ekström2020-08-18
| | | | | | | | | | | While having the possibility of non-NOPTS values that can suddenly jump in time due to adjustments to match PCR is not nice for DVB subtitles, apparently the parser for this format bases its behavior on whether the packets' timestamps are NOPTS or not. Thus while we can adjust timestamps, we should exclude DVB subtitles from the timestamp unsetting logic. Fixes #8844

* avformat/mlvdec: Check for existence of AVIOContext before using itAndreas Rheinhardt2020-08-18
| | | | | | | | | | | The mlv demuxer supports input split into multiple files; if invalid data is encountered when parsing one of the subsequent files, that file is closed. But at this point some index entries belonging to this file might already have been added. In this case, the read_packet function might try to use the AVIOContext (which is NULL) to read data which will of course crash. This commit fixes this.

* avformat/ty: Remove write-only array and variableAndreas Rheinhardt2020-08-11
| | | | | | | | | | | | | | | | Up until now, the TiVo demuxer parse an array of SEQ entries, yet it has never ever made any use of them. In fact, parse_master, the function parsing said table, only influenced the outside world in three ways: Via an excessive amount of error message in case a certain parameter is not what it expected; via an allocation (the aforementioned write-only array); and by setting a certain parameter (ty->cur_chunk_pos), but that parameter is always overwritten before it is used (it is overwritten in get_chunk() on success and if get_chunk() fails, the error is returned to the caller anyway). So remove the array and the function used to parse it. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avformat/mpegts: Don't leave context in inconsistent state upon errorAndreas Rheinhardt2020-08-10
| | | | | | | | | | | | | | | Up until now, opening a section filter works as follows: A filter is opened and (on success) attached to the MpegTSContext. Then a buffer for said filter is allocated and upon success attached to the section filter; on error, the filter is simply freed without removing it from the MpegTSContext, leaving the latter in an inconsistent state. This leads to use-after-frees lateron. This commit fixes this by allocating the buffer first; the filter is only opened if the buffer could be successfully allocated.
