* get_cabac_inline_x86: Don't inline if 32-bit clang on windowsChristopher Degawa2021-08-19
| | | | | | | | | Fixes https://trac.ffmpeg.org/ticket/8903 relevant https://github.com/msys2/MINGW-packages/discussions/9258 Signed-off-by: Christopher Degawa <ccom@randomderp.com> Signed-off-by: Martin Storsjö <martin@martin.st>
* avcodec/h264dsp, h264idct: Fix lengths of array parametersAndreas Rheinhardt2021-08-08

* Remove/replace some unnecessary avcodec.h inclusionsAndreas Rheinhardt2021-07-22

* avutil/internal, swresample/audioconvert: Remove cpu.h inclusionsAndreas Rheinhardt2021-07-22
| | | | | | | | | | These inclusions are not necessary, as cpu.h is already included wherever it is needed (via direct inclusion or via the arch-specific headers). Also remove other unnecessary cpu.h inclusions from ordinary non-headers. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Remove deprecated old encode/decode APIsAndreas Rheinhardt2021-04-27
| | | | | | | | Deprecated in commits 7fc329e2dd6226dfecaa4a1d7adf353bf2773726 and 31f6a4b4b83aca1d73f3cfc99ce2b39331970bf3. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com> Signed-off-by: James Almer <jamrial@gmail.com>
* Include attributes.h directlyAndreas Rheinhardt2021-04-19
| | | | | | | | Some files currently rely on libavutil/cpu.h to include it for them; yet said file won't use include it any more after the currently deprecated functions are removed, so include attributes.h directly. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/x86/diracdsp_init: Make functions only used here staticAndreas Rheinhardt2021-02-24
| | | | | | | | | This allowed to remove forward declarations. Because compilers expect declarations for all functions they encounter even when it is within blocks disabled via "if (0 && foo)", one has to use a real #if in ff_diracdsp_init_x86.

* avcodec/x86/diracdsp_init: Remove unused MMX functionsAndreas Rheinhardt2021-02-24
| | | | | | | | Unused since a1f3b18bf55f106c974eacb1dc831be4d2bd5277, yet as nonstatic functions the compiler can't detect this, so that these functions aren't stripped and no warning is emitted. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bumpAnton Khirnov2021-01-01

| | | | That is a more appropriate place for it.
* avcodec/mpegaudiodsp: Make ff_mpadsp_init() thread-safeAndreas Rheinhardt2020-11-24
| | | | | | | | | | The only thing missing for this is to make ff_mpadsp_init_x86() thread-safe; it currently isn't because a static table is initialized every time ff_mpadsp_init() is called (when ARCH_X86 is true). Solve this by initializing this table only once, namely together with the ordinary not-arch specific tables. This also allows to reuse their AVOnce.

* pixblockdsp, avdct: Add get_pixels_unalignedMartin Storsjö2020-05-13
| | | | | | | | | | | | | Use this in vf_spp.c, where the get_pixels operation is done on unaligned source addresses. Hook up the x86 (mmx and sse) versions of get_pixels to this function pointer, as those implementations seem to support unaligned use. This fixes fate-filter-spp on armv7.

* vp4: prevent unaligned memory access in loop filterPeter Ross2019-10-30
| | | | | | | | | | | | VP4 applies a loop filter during motion compensation, causing the block offset will often by unaligned. This produces a bus error on some platforms, namely ARMv7 NEON.
