* avcodec/arm/mpegvideo_arm: Use static_assert to check offsetsAndreas Rheinhardt2024-03-31
| | | | | | | Also move AV_CHECK_OFFSET to its only user, namely lavc/arm/mpegvideo_arm.c and rename it to CHECK_OFFSET. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-31
| | | | | | | | | | | There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* swscale/ppc/swscale_altivec: Fix build with -O0Andreas Rheinhardt2024-03-31
| | | | | | | | In this case GCC does not treat a const variable initialized to the compile-time constant "3" as a compile-time constant and errors out because the argument is not a literal value. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avfilter/buffersrc: fix overriding unknown channel layouts with negotiated oneMarton Balint2024-03-30
| | | | | | | | | | | | | | | | | | Fixes ffplay playback of unknown layouts, when SDL directly supports the audio format, such as: ffplay -f lavfi anullsrc=cl=2C,aformat=s16 Without the patch, "Channel layout change is not supported" errors are generated because buffersrc (unknown 2 channel) and buffersink (stereo) negotiated a stereo layout, but the stereo layout was never stored in the BufferSourceContext. This fixes a regression of 7251f909721a570726775acf61b2b9c28a950c76, but this is more of a regression of the avfilter channel layout conversion (1f96db959c1235bb7079d354e09914a0a2608f62).

* avcodec/h264_refs: Use smaller scope, don't use av_uninitAndreas Rheinhardt2024-03-30
| | | | | | | | | In particular, declare iterators with loop scope. Also remove av_uninit while at it, because they are now unnecessary due to the changes of the preceding commit. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/h264_refs: Rewrite code to make control flow clearerAndreas Rheinhardt2024-03-30
| | | | | | | | | | | | | | While this change IMO makes the control flow clearer for the human reader, it is especially important for GCC: It erroneously believes that it is possible to enter the SHORT2(UNUSED|LONG) cases without having entered the preceding block that initializes pic, frame_num, structure and j; it would emit -Wmaybe-uninitialized warnings for these variables if they were not pseudo- initialized with av_uninit(). This patch allows to remove the latter. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/hevc_ps: fix the problem of memcmp losing effectivenessTong Wu2024-03-29
| | | | | | | | | | | HEVCHdrParams* receives a pointer which points to a dynamically allocated memory block. It causes the memcmp always returning 1. Add a function to do the comparision.

| | | | | | | | | | | Also rewrite the code so that a variable that is only used depending upon CONFIG_LIBVPX_VP9_ENCODER is not declared outside of the #if block.

| | | | | | | | | | | hevc_data.c only provides ff_hevc_diag_scan tables and neither the QSV HEVC encoder nor the HEVC parser use these directly and the indirect dependency is already accounted for in the dependencies of the hevcparse subsystem since b0c61209cd30f9ddf3356d5ded6df488f25d1bd5, so remove these spurious dependencies.

* all: Don't use ATOMIC_VAR_INITAndreas Rheinhardt2024-03-28
| | | | | | | | | | | | | | | | | | | | C11 required to use ATOMIC_VAR_INIT to statically initialize atomic objects with static storage duration. Yet this macro was unsuitable for initializing structures [1] and was actually unneeded for all known implementations (this includes our compatibility fallback implementations which simply wrap the value in parentheses: #define ATOMIC_VAR_INIT(value) (value)). Therefore C17 deprecated the macro and C23 actually removed it [2]. Since commit 5ff0eb34d2b1089d3dd9f27fdb51520001709138 we default to C17 if the compiler supports it; Clang warns about ATOMIC_VAR_INIT in this mode. Given that no implementation ever needed this macro, this commit stops using it to avoid this warning.

* fftools/ffmpeg_enc: stop copying demuxer side data to the muxerAnton Khirnov2024-03-28

* lavc/encode: map AVCodecContext.decoded_side_data to coded_side_dataAnton Khirnov2024-03-28

| | | | It will be shared with encoding code.
* lavc/frame_thread_encoder: avoid assigning a whole AVCodecContextAnton Khirnov2024-03-28
| | | | | | | | | It is highly unsafe, as AVCodecContext contains many allocated fields. Almost everything needed by worker threads should be covered by routing through AVCodecParameters and av_opt_copy(), except for a few fields that are copied manually. avcodec_free_context() can now be used for per-thread contexts.

* fftools/ffmpeg_dec: apply cropping manuallyAnton Khirnov2024-03-28
| | | | | | | | | lavfi does not require aligned buffers, so we can safely apply top/left cropping by any amount, without passing any special flags to lavc. Longer term, an even better solution would probably be auto-inserting the crop filter (or its hwaccel versions) as needed. Multiple FATE tests no longer need -flags unaligned.
