* avcodec/mpegaudiodsp: Make initializing synth windows thread-safeAndreas Rheinhardt2020-11-24
| | | | | | | | | | These arrays are used by the Musepack decoders, the MPEG audio decoders as well as qdm2 and up until now, these arrays might be initialized more than once, leading to potential data races as well as unnecessary initializations. Therefore this commit ensures that each array will only be initialized once. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* 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.

* avcodec/mpegaudiodsp: Combine initializing float and int tablesAndreas Rheinhardt2020-11-24
| | | | | | | This avoids code duplication in the functions used to initialize them and allows to remove an AVOnce. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

| * mpegaudiodsp: Change type of array stride parameters to ptrdiff_tDiego Biurrun2016-09-29
| | | | | | | | | | This avoids SIMD-optimized functions having to sign-extend their stride argument manually to be able to do pointer arithmetic.
