* proresdsp: add idct_put_bayerLynne4 days1-0/+17
| | | | | This commit adds a 12-bit DCT function to directly write to Bayer images. Will be used in the following commit.
* avcodec/simple_idct: Move ProRes-only code to proresdsp.cAndreas Rheinhardt2025-02-271-3/+49
| | | | Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/proresdsp: Make put_pixels truely ptrdiff_t compatibleAndreas Rheinhardt2025-02-271-7/+5
| | | | | | | | | It currently uses an intermediate int which wouldn't work if linesize exceeded the range of int and inhibits compiler optimizations. Also switch to pointer arithmetic and use smaller scope. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/prores{dec,dsp}: Remove always-false checksAndreas Rheinhardt2025-02-271-5/+4
| | | | | | | | | | | | avctx->bits_per_raw_sample is always 10 or 12 here; the checks have been added in preparation for making bits_per_raw_sample user-settable via an AVOption, but this never happened. While just at it, also set unpack_alpha earlier (where bits_per_raw_sample is set). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/proresdsp: Pass necessary parameter directlyAndreas Rheinhardt2023-09-111-4/+4
| | | | | | Only avctx->bits_per_raw_sample is used. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt2022-06-151-2/+3
| | | | | | | | | | | | | | | | | | This is more spec-compliant because it does not rely on dead-code elimination by the compiler. Especially MSVC has problems with this, as can be seen in https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/296373.html or https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/297022.html This commit does not eliminate every instance where we rely on dead code elimination: It only tackles branching to the initialization of arch-specific dsp code, not e.g. all uses of CONFIG_ and HAVE_ checks. But maybe it is already enough to compile FFmpeg with MSVC with whole-programm-optimizations enabled (if one does not disable too many components).

|\ | | | | | | | | | | | | * commit '3fd22538bc0e0de84b31335266b4b1577d3d609e': prores: Change type of stride parameters to ptrdiff_t Merged-by: James Almer <jamrial@gmail.com>
| * prores: Change type of stride parameters to ptrdiff_tDiego Biurrun2016-08-261-3/+3
| | | | | | | | | | | | | | This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "linesize" everywhere.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the first names of authors sounds somewhat unprofessional and might be considered offensive which is not intended. The new names use the initials of the authors due to simplicity and the possibility to apply it consistently without the need to find political correct names for each future case where alternative codecs might exist.
