* avcodec/hevcdec: check that the local context list was allocated before ↵James Almer2021-02-11
| | | | | | | | | | | | | | | | | | | dereferencing it Since the decoder is not flagged as init cleanup capable, hevc_decode_free() is being called manually if the hevc_decode_extradata() call fails at the end of hevc_decode_init(). In a frame threading scenario, however, if AVCodec->init() returns an error, ff_frame_thread_free() will be called regardless of the above flag being set or not, resulting in hevc_decode_free() being called a second time for the same context. Workaround this by ensuring pointers are not dereferenced if they are NULL, and set the decoder as init cleanup capable while at it. Fixes ticket #9099. Signed-off-by: James Almer <jamrial@gmail.com>

| | | | | | | | Several compile-time checks can be improved because mcsel is not used for MPEG-1/2 (it is only used for MPEG-4) and because MPEG-1/2 is the only user of ff_mpv_motion that uses MV_TYPE_16X8 and MV_TYPE_DMV. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

| | | | | | | | In case trellis is outside of 0..23, an invalid shift and/or a signed integer overflow happens; furthermore, it can lead to the request to allocate nonsense amounts of memory. So validate first. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* mjpegdec: stop setting the QP tableAnton Khirnov2021-02-08
| | | | | | | MJPEG does not have a single quantiser scale, so this does not fit into the intended API use. This removes the last use of the long-deprecated QP table API.
* avcodec/ac3enc: Share options and defaultsAndreas Rheinhardt2021-02-07
| | | | | | | | | | Both AC-3 encoder share the same options, yet they are nevertheless duplicated in the binary; and the options applying to the EAC-3 encoder are a proper subset of the options for the AC-3 encoders, so that it can use the same options as the former by putting the options specific to AC-3 at the front. This commit implements this. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/aacdec_fixed: Move fixed-point sinewin tables to its only userAndreas Rheinhardt2021-02-07
| | | | | | | | | | | | | | | | | | | | | | The fixed-point AAC decoder is the only user of the fixed-point sinewin tables from sinewin; and it only uses a few of them (about 10% when counting by size). This means that guarding initializing these tables by an AVOnce (as done in 3719122065863f701026632f610175980d42b05a) is unnecessary for them. Furthermore the array of pointers to the individual arrays is also unneeded. Therefore this commit moves these tables directly into aacdec_fixed.c; this is done by ridding the original sinewin.h and sinewin_tablegen.h headers completely of any fixed-point code at the cost of a bit of duplicated code (the alternative is an ugly ifdef-mess). This saves about 58KB from the binary when using hardcoded tables (as these tables are hardcoded in this scenario); when not using hardcoded tables, most of these savings only affect the .bss segment, but the rest (< 1KB) contains relocations (i.e. savings in .data.rel.ro).
