* avcodec/vp3dsp: Use unsigned constant to avoid undefined integer overflow in ↵Michael Niedermayer2020-11-13
| | | | | | | | | | | ff_vp3dsp_set_bounding_values() Fixes: signed integer overflow: 64 * 33686018 cannot be represented in type 'int' Fixes: 26911/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_THEORA_fuzzer-4904975073017856 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Reviewed-by: Peter Ross <pross@xvid.org> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* vp4: prevent unaligned memory access in loop filterPeter Ross2019-10-30
| | | | | | | | | | | | VP4 applies a loop filter during motion compensation, causing the block offset will often by unaligned. This produces a bus error on some platforms, namely ARMv7 NEON. This patch adds a unaligned version of the loop filter function pointer to VP3DSPContext. Reported-by: Mike Melanson <mike@multimedia.cx> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avcodec/vp3dsp: add 10 coefficient version of the VP3 IDCTPeter Ross2019-01-26
| | | | | | This version of the IDCT is used by the VP6 decoder. Signed-off-by: Peter Ross <pross@xvid.org>

| | | | | | | | | | | | | | This avoids SIMD-optimized functions having to sign-extend their stride argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "stride" everywhere.

| | | | | | | | | | | | Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.
