* avformat/westwood_vqa: Store VQFL codebook chunksPekka Väänänen2021-10-14
| | | | | | | High color 15-bit VQA3 video streams contain high level chunks with only codebook updates that shouldn't be considered new frames. Now the demuxer stores a reference to such VQFL chunks and returns them later along with a VQFR chunk with full frame data.

* Revert "avfilter/vf_idet: reduce noisyness if the filter has been auto inserted"Andreas Rheinhardt2021-10-11
| | | | | | | | | | | This reverts commit 723c37d3b7b5555f23bfdfe3e5c3599543c06332. Said commit was in preparation for auto-inserting the idet filter. This has never happened; even if it did, the code is wrong, because it segfaults if the filter instance doesn't have a name (having one is not mandatory). Furthermore, it is documented for libavfilter to not assign any semantics to the name, which this check violates. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/mpegts: fix max_packet_size in mpegts payload parsingMarton Balint2021-10-10
| | | | | | | | | | | | | | | | | The maximum allowed useful PES payload data was set to PES_packet_length, but it is in fact smaller by the length of the PES header. This changes how corrupt streams are packetized: - If PES header length is bigger than PES_packet_length then the PES packet payload will be handled as an unbound packet - PES packets with payload across multiple MPEGTS packets will always be splitted if with the next chunk of data the payload should exceed PES_packet_length, previously a PES_header_length amount of excess was allowed. Fixes ticket #9355. Signed-off-by: Marton Balint <cus@passwd.hu>
* avformat/mpegts: rename PES total_size to PES_packet_lengthMarton Balint2021-10-10
| | | | | | | | | This renames PESContext->total_size to PESContext->PES_packet_length and keeps it 0 for unbound packets, so its name and semantics will match the standard. There should be no change in functionality. Signed-off-by: Marton Balint <cus@passwd.hu>

* avfilter/asrc_flite: Fix races upon (un)registering voicesAndreas Rheinhardt2021-10-10
| | | | | | | | | | | | | | | | | | The voice registration system in libflite is broken: It is not thread-safe and also not based on internal counters; instead any call to unregister a voice frees said voice even if there are still many other users of said voice who have also registered said voice. While there is no way to guard against another library unregistering voices behind our back, we can at least be correct in the absence of other users of libflite. The current code already tried this by using a reference count of our own for each voice; but the implementation of this is not thread-safe at all. Fix this by using a mutex to guard all of libavfilter's libflite registration and unregistration calls, thereby being thread-safe in the absence of other libflite users.

* avfilter/asrc_flite: Fix use-after-freesAndreas Rheinhardt2021-10-10
| | | | | | | | | | | | | When an flite filter instance is uninitialized and the refcount of the corresponding voice_entry reaches zero, the voice is unregistered, yet the voice_entry's pointer to the voice is not reset. (Whereas some other pointers are needlessly reset.) Because of this a new flite filter instance will believe said voice to already be registered, leading to use-after-frees. Fix this by resetting the right pointer instead of the wrong ones. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
