Real files do skip coding 0 bits at the end, thus this kind of check does not work reliable. Fixes: Ticket 8770 Fixes: dst-256fs44-6ch-refdstencoder.dff The samplerate is specified in ISO/IEC 14496-3:2005(E) as one of 3 fixed values, this also can be used to limit the duration and avoid the timeout This reverts commit f6df99db.

Fix two cases of memleaks: 1. The leak of dv_demux 2. The leak of dv_fctx upon dv_demux allocate failure Signed-off-by:

Andreas Rheinhardt authored
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. Signed-off-by:

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. Reviewed-by:

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 163bb9ac.) Signed-off-by:

If adding two ints overflows, it doesn't matter whether the result will be stored in an unsigned or not; and checking afterwards does not make it retroactively defined. Signed-off-by:

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. Signed-off-by: -
