* avcodec/diracdsp: Don't cast const away unnecessarilyAndreas Rheinhardt2022-07-31

* all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt2022-06-15
| | | | | | | | | | | | | | | | | | 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).

* diracdec: add support for 12 bit videosRostislav Pehlivanov2016-01-21
| | | | | | | | | The DSP lacked a function needed to convert signed to unsigned. This was ignored when originally adding support and templating for bit depths greater than 8. The 10 bit function was used for 12 bit pictures and resulted in an improper conversion. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
