* avcodec/dstdec: Replace AC overread check by sample rate checkMichael Niedermayer2020-07-021-7/+6
| | | | | | | | | | | | | 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.

* libavcodec/jpeg2000.c: Precinct size check removedGautam Ramakrishnan2020-06-303-5/+5
| | | | | | | | | | This patch removes a check which throws an error if the log2 precinct width/height is 0. The standard allows the first component to have 0 as the log2 width/height. However, to ensure proper intialization of coding style, an extra check has been added. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
