* avcodec/libx264: Set min build version to 158 for msvcMatt Oliver2022-06-11
| | | | | | | | | | | | | | | | | | | | | | | Was "[PATCH] libx264: Do not explicitly set X264_API_IMPORTS" Setting X264_API_IMPORTS only affects msvc builds and it breaks linking to static builds (although is required for shared builds). This flag is set by x264 in its pkgconfig as required since build 158 (a615f027ed172e2dd5380e736d487aa858a0c4ff) from July 2019. So this patch updates configure to require a newer x264 build that correctly sets the imports flag. The min version requirement of 158 is applied for msvc builds only. This is also removing the check for 'libx264 without pkg-config' which was left for compatibility reasons about 7 years ago when the pkg-config check was introduced by commit e06263ef1e0e172b2c76070b3dc739411af08e82.

* tools/target_dec_fuzzer: add a custom get_buffer2() implementationJames Almer2022-06-06
| | | | | | | | | | | | Unlike avcodec_default_get_buffer2(), this version does not allocate more than what the lavu image helper functions consider should be allocated for a given frame. Since the get_buffer2() documentation does not require any kind of buffer padding for any of the planes, this should help detect bugs in our DR1 decoders if they read beyond the end of the buffer, simulating what some library users might experience when they use their own custom get_buffer2() implementations.

| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for max frame size: - max_frame_size (bytes) to indicate the max allowed size for frame. Control each encoded frame size into target limitation size by adjusting whole frame's average QP value. The driver will use multi passes to adjust average QP setp by step to achieve the target, and the result may not strictly guaranteed. Frame size may exceed target alone with using the maximum average QP value. The failure always happens on the intra(especially the first intra frame of a new GOP) frames or set max_frame_size with a very small number. example cmdline: ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -f rawvideo \ -v verbose -s:v 352x288 -i ./input.yuv -vf format=nv12,hwupload \ -c:v h264_vaapi -profile:v main -g 30 -rc_mode VBR -b:v 500k \ -bf 3 -max_frame_size 40000 -vframes 100 -y ./max_frame_size.h264 Max frame size was enabled since VA-API version (0, 33, 0), but query is available since (1, 5, 0).

* avutil/avframe: fix channel layout checks in av_frame_copy()James Almer2022-06-05
| | | | | | | | | | | | | | | Normally, both the source and dest frame would have only the old API fields set, only the new API fields set, or both set. But in some cases, like when calling av_frame_ref() using a non reference counted source frame where only the old channel layout API fields were populated, the result would be the dst frame having both the new and old fields populated. This commit takes this into account and fixes the checks by calling av_channel_layout_compare() only if the source frame has the new API fields set, and doing sanity checks for the source frame old API fields if the new ones are not set.

* Makefile: avoid cp-ing over existing executable filesrcombs2022-06-01
| | | | | | | | | On macOS, code-signing information for executables (including those signed automatically by the linker) is cached by the system on a per-inode basis. The cp(1) tool will truncate and overwrite an existing file if present, so we need to delete it first to avoid strange crashes.
