* seek: Fix crashes in ff_seek_frame_binary if built with latest Clang 14Martin Storsjö2021-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | Passing an uninitialized variable as argument to a function is undefined behaviour (UB). The compiler can assume that UB does not happen. Hence, the compiler can assume that the variables are never uninitialized when passed as argument, which means that the codepaths that initializes them must be taken. In ff_seek_frame_binary, this means that the compiler can assume that the codepaths that initialize pos_min and pos_max are taken, which means that the conditions "if (sti->index_entries)" and "if (index >= 0)" can be optimized out. Current Clang git versions (upcoming Clang 14) enabled an optimization that does this, which broke the current version of this function (which intentionally left the variables uninitialized, but silencing warnings about being uninitialized). See [1] for discussion on the matter. [1] https://reviews.llvm.org/D105169#3069555 Signed-off-by: Martin Storsjö <martin@martin.st>

* 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.

* avformat/librist: replace deprecated functionsGijs Peskens2021-10-10
| | | | | | | | | | | This gets rid of of rist_receiver_data_read, rist_receiver_data_block_free and rist_parse_address these functions have been deprecated since librist release v0.2.1 and are replaced with functions suffixed with 2. I added a version macro check at the top of the file to ensure ffmpeg can still be compiled against older versions.

* 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>

* avformat/allformats: Fix data race when accessing devices listsAndreas Rheinhardt2021-10-09
| | | | | | | | | | | | | | | | | | Up until now setting the input and output devices lists is guarded by a mutex. This prevents data races emanating from multiple concurrent calls to avpriv_register_devices() (triggered by multiple concurrent calls to avdevice_register_all()). Yet reading the lists pointers was done without any lock and with nonatomic variables. This means that there are data races in case of concurrent calls to av_(de)muxer_iterate() and avdevice_register_all() (but only if the iteration in av_(de)muxer_iterate exhausts the non-device (de)muxers). This commit fixes this by putting said pointers into atomic objects. Due to the unavailability of _Atomic the object is an atomic_uintptr, leading to ugly casts. Switching to atomics also allowed to remove the mutex currently used in avpriv_register_devices(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/{isom,mov,movenc}: add support for CMAF DASH rolesJan Ekström2021-10-04
| | | | | | | | | | | | | | | | This information is coded in a standard MP4 KindBox and utilizes the scheme and values as per the DASH role scheme defined in MPEG-DASH. Other schemes are technically allowed, but where multiple schemes define the same concepts, the DASH scheme should be utilized. Such flagging is additionally utilized by the DASH-IF CMAF ingest specification, enabling an encoder to inform the following component of the roles of the incoming media streams. A test is added for this functionality in a similar manner to the matroska test. Signed-off-by: Jan Ekström <jan.ekstrom@24i.com>
