Andreas Rheinhardt	0f0f2ab0c3	avcodec/cavsdsp: Fix undefined left shifts of negative numbers Affected the ffmpeg-filter_colorkey FATE-test (but only if the C version of idct8_add is used and not e.g. the x86 SSE2 version). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Fixes: left shift of negative value -107 Fixes: 20398/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_CAVS_fuzzer-5725389278412800 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago

Diego Biurrun	f81be06cf6	cavs: Change type of stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar.	8 years ago

Mans Rullgard	6efb698883	cavsdsp: set idct permutation independently of dsputil CAVS uses its own idct so using dsputil to set the permutation is fragile. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
