* avcodec/itut35: rename some provider codesMaryla Ustarroz-Calonge2025-08-076-10/+10
| | | | | | | | | | | | | | | | | | In general, a provider code corresponds to a company/organization, and the name should be that of the company, not of a given feature. The feature is signalled in the "provider oriented code". The exception is HDR Vivid, where the code 0x0004 indicates the HDR Vivid feature itself rather than CUVA (China UHD Video Industry Alliance), according to the UHD World Associations 'HDR Video Technology Part 2-1 Application Guide to System Integration' document.

| | | | | | | | | | | | | This should be done by fate. This script already blocks security fixes (https://code.ffmpeg.org/FFmpeg/FFmpeg/actions/runs/1046/jobs/0) IMHO its not good 1. to add commit message formating rules, never discussed or agreed 2. to expect developers to push commits trial and error style, make fate can test this already and tell the devlopers before pushing, saving him time This reverts commit cc6ad703b41e318bd1e4cb6196defaf505dbfea3.

* configure: don't disable '-ftree-vectorize' on GCC >= 13 on major architecturesJiawei2025-08-062-1/+20
| | | | | | | | | | | | | | | | | | | | | This changes configure to stop disabling -ftree-vectorize on GCC versions 13 and newer, on major architectures. Background: - Original `-fno-tree-vectorize` was added in 2009 in commit 973859f5230e to avoid compiler errors. - Re-enabled in 2016 in commit cb8646af24bd but caused failures due to inline CABAC assembly issues and was disabled again in fd6dbc53855fb. - Commit 182663a58a7a in 2023 fixed the inline CABAC assembly issues. - Recent versions of GCC, in particular 13 and newer, seem to generally work reliably with respect to vectorization, although bugs have been observed on Loongarch. Cautiously allow the GCC default of having vectorization enabled, on major architectures where we expect to see enough testing. If further issues are observed, they should be reported and noted here in configure, so the workarounds can be scoped and version limited.

* configure: treat unrecognized flags as errors on MSVCKacper Michajłow2025-08-051-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is important for feature checking to work correctly. It can happen that an unrecognized flag passes the compile test with only a warning, while failing in preprocessor-only check with an error. This causes all test_cpp calls to fail and silently produces arguably broken MSVC builds. Also, all check_* functions don't work as expected, because they assume the check passed, even though there was a warning. Additionally, this brings the behavior in line with GCC/Clang based builds, failing early on unrecognized flags instead of silently continuing with warnings in the log. The /options:strict option is available starting in Visual Studio 2022 version 17.0. Because of that, we cannot use check_cflags alone, as it would add this flag for older MSVC versions and produce warnings. So, we need to manually perform a version check. A bit of a chicken and egg problem. Perform the version check before adding extra flags from the user to ensure we don't silently fail the preprocessor check due to invalid flags on older MSVC versions. Note that behavior differs depending on whether we are compiling or only preprocessing. This fixes silent different between handling: `cl.exe -P foo c.c` c1: fatal error C1083: Cannot open source file: 'foo': No such file or directory `cl.exe -c foo c.c` cl : Command line warning D9024 : unrecognized source file type 'foo', object file assumed Where -P fails, while -c throws warnings only. Of course `foo` is completely bogus here, but depends on the flags or configuration this may be unsupported argument. Or even some converted path from MSYS when run inside it. The objective is to always error out instead of silently hiding this. Use check_cflags even after the _MSC_FULL_VER check, for non-MSVC compilers. For example Clang-CL impersonate MSVC, but does not support -options:strict flag currently. Signed-off-by: Kacper Michajłow <[email protected]>

* configure: don't use dangling temp file stateKacper Michajłow2025-08-051-0/+2
| | | | | | | There was implicit assumption that the $TMPC file is empty when doing --cpu=host checks. This breaks if any check is done before that. Signed-off-by: Kacper Michajłow <[email protected]>
* hwcontext_vulkan: fix exporting multi-plane DRM modifiersRussell Greene2025-08-051-10/+94
| | | | | | | | | | | | | | | | | | | | | | Previously, it was assumed that `drmFormatModifierPlaneCount` was one for all modifiers when exporting, which is not always the case, in particular for AMD GPUs and maybe others. Fetch the number of memory planes and fill the structs appropriately in this situation. The encoded stream is still bad in the case whre modifers are involved, but I think this patch still stands on its own and I suspect that may be a driver bug. A potential improvement that could be make is to cache the format information, so we can avoid the two GetPhysicalDeviceFormatProperties2 calls for each export, as well as the allocation. I doubt this is very expensive, but seemed worth noting. v2 changes: query the format properties with the test image created in `vulkan_frames_init` to avoid allocating space for the query during export Signed-off-by: Russell Greene <[email protected]>
