* lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bumpAnton Khirnov2021-01-01
| | | | They are not properly namespaced and not intended for public use.
* avcodec/dsd: Make initializing DSD tables thread-safeAndreas Rheinhardt2020-12-08
| | | | | | | This automatically makes the DSD formats as well as DST and WavPack init-threadsafe. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/dstdec: Replace AC overread check by sample rate checkMichael Niedermayer2020-07-02
| | | | | | | | | | | | | Real files do skip coding 0 bits at the end, thus this kind of check does not work reliable. Fixes: Ticket 8770 Fixes: dst-256fs44-6ch-refdstencoder.dff The samplerate is specified in ISO/IEC 14496-3:2005(E) as one of 3 fixed values, this also can be used to limit the duration and avoid the timeout This reverts commit f6df99dba1ae64b05d08fba8160d13eb9795042f.
