* avcodec/vvc/dec: fix possible null-pointer dereferenceMarvin Scholz2025-06-121-1/+2
| | | | | | | | | When checking for filmgrain here, needs_fg can be true even when film_grain_characteristics is NULL (when aom_film_grain.enable is true), therefore this check could end up dereferencing film_grain_characteristics even though it is NULL. Fix CID 1648347

* avutil/intmath: use AV_HAS_BUILTIN to detect builtin availabilityKacper Michajłow2025-06-122-9/+7
| | | | | | | | | Fixes use of bultins on clang x86_64-pc-windows-msvc which does not define any __GNUC__. Also on other targets __GNUC__ is defined to 4 by default, so any feature testing based on version is not really valid.

* lavfi/f_sendcmd: clear Command on alloc failureMarvin Scholz2025-06-111-0/+1
| | | | | | | | If the command array failed to allocate, the current parsed Command has to be cleared, else memory allocated for it would be leaked. Fix CID 1638635

* hwcontext_vulkan: add a setting to limit queuesLynne2025-06-101-2/+15
| | | | | If its a problem, you'll likely want to set it to 1 than more fine-grained control, which you can already do via the API.
* hwcontext_vulkan: minimize queue allocation on NVIDIALynne2025-06-101-1/+19
| | | | | | | | | | | | On NVIDIA, there's a global maximum limit of approximately 112 queues, which means it takes ONLY 7 total programs using the maximum amount of queues to cause the driver to error out/*segfault* during initialization. Also, each queue takes about 30ms to allocate, which quickly adds up. This reduces the queues allocate to the minimum that we would be happy with. Its not worth limiting decode/encode queues as they're generally not a lot, and do help.
* hwcontext_vulkan: do not use optical flow queueus by defaultLynne2025-06-101-8/+0
| | | | | We don't use them, and on NVIDIA, each queue takes around 30ms to allocate, and the driver has a global limit of ONLY 112 queues.
* configure: rename POSIX ioctl checkLeo Izen2025-06-082-3/+3
| | | | | | | | | | | | | | | Commit 00b64fca55a3a009c9d0e391c85f4fd3291e5d12 introduced configure detection for HAVE_POSIX_IOCTL but unfortunately this conflicts with v4l-utils version 1.30, which itself checks for #ifdef HAVE_POSIX_IOCTL in a public header and erroneously determines it to be true because we define this to be 0. Since this is only used for avdevice/v4l2, we rename this to something else, namely ioctl_posix, simply to prevent the name conflict with the file /usr/include/libv4l2.h at least until they can upstream a fix on their end.

* avutil/x86/intmath: remove inline asm implementations for clip functionsJames Almer2025-06-071-62/+0
| | | | | | | | | | | GCC/Clang is smart enough to emit minss/maxss the same way as these functions. The only theoretical benefit was in x86_32, where x87 floats are used, but the penalty of making the clipping opaque to the compiler's scheduler plus moving values from mmx regs to xmm and back will offset any potential speedup. x86_32 builds targetting anything made in the last two decades and a half should use -msse -mfp=sse anyway.

* libavformat/rtpdec: Fix RTP timestamp wraparound in Producer Reference TimeClément Péron2025-06-081-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rtp_set_prft() function incorrectly calculates the timestamp delta when RTP timestamps wrap around the 32-bit boundary. The current code: delta_timestamp = (int64_t)timestamp - (int64_t)s->last_rtcp_timestamp; treats both timestamps as large positive values, causing wraparound to produce a large negative delta instead of the correct small positive delta. For example, with a 90kHz video clock: - last_rtcp_timestamp = 0xFFFFFF00 (near wraparound) - timestamp = 0x00000100 (after wraparound) - Current result: delta ≈ -4.3 billion ticks ≈ -47,721 seconds - Expected result: delta ≈ +512 ticks ≈ +0.006 seconds This causes prft->wallclock to jump backward by approximately: - 90kHz video: ~47,721 seconds (~13.25 hours) - 48kHz audio: ~89,478 seconds (~24.9 hours) - 8kHz audio: ~536,871 seconds (~6.2 days) Fix by casting the subtraction result to int32_t, which correctly handles wraparound through modular arithmetic: delta_timestamp = (int32_t)(timestamp - s->last_rtcp_timestamp); This ensures the delta is always in the range [-2^31, 2^31-1], making wraparound produce the correct small positive values. Fixes timing jumps in applications that rely on Producer Reference Time for media synchronization.
