* avformat/mov: fix memleaksZhao Zhili2020-07-01

* libavformat/mov: Fix memleaks when demuxing DV audioAndreas Rheinhardt2020-07-01
| | | | | | | | | | | | | | | | | | | | | The code for demuxing DV audio predates the introduction of refcounted packets and when the latter was added, changes to the former were forgotten. This meant that when avpriv_dv_produce_packet initialized the packet containing the AVBufferRef, the AVBufferRef as well as the underlying AVBuffer leaked; the actual packet data didn't leak: They were directly freed, but not via their AVBuffer's free function. https://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket4671/dir1.tar.bz2 contains samples for this (enable_drefs needs to be enabled for them). Moreover, errors in avpriv_dv_produce_packet were ignored; this has been changed, too. Furthermore, in the hypothetical scenario that the track has a palette, this would leak, too, so reorder the code so that the palette code appears after the DV audio code.

* libavcodec/jpeg2000.c: Precinct size check removedGautam Ramakrishnan2020-06-30
| | | | | | | | | | This patch removes a check which throws an error if the log2 precinct width/height is 0. The standard allows the first component to have 0 as the log2 width/height. However, to ensure proper intialization of coding style, an extra check has been added. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* lavf/movenc: Use a dynamic buffer when writing the mfra boxDerek Buitenhuis2020-06-28
| | | | | | | | | | | When doing streamed output, with e.g. +dash, if the mfra box ended up being larger than the AVIOContext write buffer, the (unchecked) seeking back to update the box size would silently fail and produce an invalid mfra box. This is similar to how other boxes are written in fragmented mode. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

| | | | | | | | | | Nothing written in avformat_write_trailer() for the submuxers will be output anyway because the AVIOContexts used for actual output have been closed before the call. Writing the trailer of the subcontext has probably only been done in order to free the memory allocated by the submuxer. And this job has been taken over by the deinit functions.

* avformat/avc, mxfenc: Avoid allocation of H264 SPS structure, fix memleakAndreas Rheinhardt2020-06-26
| | | | | | | | | | | | | | | | | | | | | | Up until now, ff_avc_decode_sps would parse a SPS and return some properties from it in a freshly allocated structure. Yet said structure is very small and completely internal to libavformat, so there is no reason to use the heap for it. This commit therefore changes the function to return an int and to modify a caller-provided structure. This will also allow ff_avc_decode_sps to return better error codes in the future. It also fixes a memleak in mxfenc: If a packet contained multiple SPS, only the SPS structure belonging to the last SPS would be freed, the other ones would leak when the pointer is overwritten to point to the new SPS structure. Of course, without allocations there are no leaks. This is Coverity issue #1445194. Furthermore, the SPS structure has been renamed from H264SequenceParameterSet to H264SPS in order to avoid overlong lines.

* avformat/webvttdec: Accept \r as newlineAndreas Rheinhardt2020-06-26
| | | | | | | | | | | | | After parsing the end timestamp of a WebVTT cue block, the current code skips everything after the start of the timestamp that is not a \t, ' ' or \n and treats what is next as the start of a WebVTT cue settings list. Yet if there is no such list, but a single \r, this will skip a part of the cue payload (namely everything until the first occurence of \t, ' ' or \n) and treat what has not been skipped as the beginning of the WebVTT cue settings list that extends until the next \r or \n (or the end).
