| | | | | | | | | | | No audio stream is created unconditionally and if none has been created, no packet with stream_index 1 may be returned.

* libavformat/mov: Fix memleaks when demuxing DV audioAndreas Rheinhardt2020-07-011-10/+13
| | | | | | | | | | | | | | | | | | | | | | | 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.

* avformat/avc, mxfenc: Avoid allocation of H264 SPS structure, fix memleakAndreas Rheinhardt2020-07-013-25/+21
| | | | | | | | | | | | | | | | | | | | | | | | 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/aviobuf: Also return truncated buffer in avio_get_dyn_buf()Andreas Rheinhardt2020-07-011-2/+2
| | | | | | | | | | | | | | | | | | | Two kinds of errors can happen when working with dynamic buffers: (Re)allocation errors or truncation errors (one has to truncate the buffer to a size of INT_MAX because avio_close_dyn_buf() and avio_get_dyn_buf() both return an int). Right now, avio_get_dyn_buf() returns an empty buffer in either case. But given that avio_get_dyn_buf() does not destroy the dynamic buffer, one can return the buffer in case of truncation and let the user check the error flags and decide for himself instead of hardcoding a single way to proceed in case of truncation. (This actually restores the behaviour from before commit 163bb9ac0af495a5cb95441bdb5c02170440d28c.)

* avformat/mov: Fix memleak upon encountering repeating tagsAndreas Rheinhardt2020-06-151-0/+3
| | | | | | | | | | | | | | mov_read_custom tries to read three strings belonging to three different tags. When an already encountered tag is encountered again, a new buffer for the string to be read is allocated and stored in the pointer destined for this particular tag. But in this scenario, said pointer already holds the address of the string read earlier, leading to a leak. This commit therefore aborts the reading process upon encountering an already encountered tag.

* avformat/mov: Fix memleaks upon read_header failureAndreas Rheinhardt2020-06-151-16/+17
| | | | | | | | | | | | | | | | By default, a demuxer's read_close function is not called automatically if an error happens when reading the header; instead it is up to the demuxer to clean up after itself in this case. The mov demuxer did this by calling its read_close function when it encountered some errors when reading the header. Yet for other errors (mostly adding side-data to streams) this has been forgotten, so that all the internal structures of the demuxer leak. This commit fixes this by making sure mov_read_close is called when necessary.

* avformat/matroskadec: Move AVBufferRef instead of copying, fix memleakAndreas Rheinhardt2020-06-151-3/+2
| | | | | | | | | | | | | | EBML binary elements are already made reference-counted when read; so when populating the AVStream.attached_pic, one does not need to allocate a new buffer for the data; instead the current code just creates a new reference to the underlying AVBuffer.

* lavf/prompeg: prompeg_write() must report data all was writtenDavid Holroyd2020-06-141-4/+2
| | | | | | | | | | | | | | | | | Previously, prompeg_write() would only report to caller that bytes we written when a FEC packet was actually created. Not all RTP packets are expected to generate a FEC packet however, so this behavior was causing avio to retry writing the RTP packet, eventually forcing the FEC state machine to send a FEC packet erroneously (and so breaking out of the retry loop). This was resulting in incorrect FEC data being generated, and far too many FEC packets to be sent (~100% FEC overhead). fix #7863 Signed-off-by: David Holroyd <[email protected]> (cherry picked from commit ffc1208266c2890a1b0e2391e0a536fe9698e69c)
