* avformat/vvc: Fix crash on allocation failure, avoid allocationsAndreas Rheinhardt2024-06-091-96/+73
| | | | | | | | | | This is the VVC version of 8b5d15530127fea54e934043a64653859de07353. (Hint: This ensures that the order of NALU arrays is OPI-VPS-SPS-PPS- Prefix-SEI-Suffix-SEI, regardless of the order in the original extradata. I hope this is right.)

* avformat/vvc: Don't use ff_copy_bits()Andreas Rheinhardt2024-06-094-5/+2
| | | | | | | | | | | There is no benefit in using it: The fast path of copying is not taken because of misalignment; furthermore we are only dealing with a few byte here anyway, so simply copy the bytes manually, avoiding the dependency on bitstream.c in lavf (which also contains a function that is completely unused in lavf).

* avcodec/hevc/Makefile: Move rules for lavc/* files to lavc/MakefileAndreas Rheinhardt2024-06-092-8/+4
| | | | | | | | | | | | If any of these files (say A) would be changed in such a way that A acquires a new dependency on another file B, building B would need to be added to all the rules that lead to A being built. Yet currently the rules for several files are spread over the lavc Makefile and the Makefile of the lavc/hevc subdir, making it more likely to be forgotten. So move the rules for these files to the lavc/Makefile. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | Yet another thing not mentioned in the spec.
* aacdec_usac: decouple TNS active from TNS data present flagLynne2024-06-082-10/+16
| | | | | The issue was that in case of common TNS parameters, TNS was entirely skipped, as tns.present was set to 0.

|
* aac: define a new profile for USACLynne2024-06-084-0/+7
| | | | This allows users to determine whether a stream is USAC or not.
* mpeg4audio: explicitly define each AOTLynne2024-06-081-40/+42
| | | | | | This makes it far easier to figure out which AOT belongs to which profile. Also, explicitly highlight the holes.
* mpeg4audio: rename AOT_USAC_NOSBR to AOT_USACLynne2024-06-082-7/+3
| | | | | | | | | | The issue is that AOT 45 isn't defined anywhere, and looking at the git blame, it seems to have sprung up through a reordering of the enum, and adding a hole. The spec does not define an explicit AOT for SBR and no SBR, and only uses AOT 42 (previously AOT_USAC_NOSBR), so just rename AOT_USAC to it and replace its use everywhere.

* libavfilter/signature_lookup: fix jaccard distanceGerion Entrup2024-06-071-1/+2
| | | | | | | | | | | | | | | Actually, the jaccard distance is defined as D = 1 - intersect / union. Additionally, the distance value is compared against a constant that must be between 0 and 1, which is not the case here. Both facts together has led to the fact, that the function always returned a matching course signature. To leave the constant intact and to avoid floating point computation, this commit multiplies with 1 << 16 making the constant effectively 9000 / (1<<16) =~ 0.14.

* checkasm: disable unaligned access emulationRémi Denis-Courmont2024-06-071-0/+6
| | | | | | | | | | | | The OS may silently fix (emulate) unaligned hardware access exceptions. This is extremely slow and code should be fixed not to rely on unaligned access on affected hardware. Accordingly this requests that the OS disable emulation and instead throw Bus error, which will be caught by checkasm's signal handler. This has no effects if the hardware supports unaligned access in hardware, since no exceptions are generated. prctl() will fail safe in that case.
