avcodec/utils: use 32pixel alignment for bink
bink supports 16x16 blocks in chroma planes thus we need to allocate enough. Fixes: out of array access Fixes: 55026/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_BINK_fuzzer-6013915371012096 Reviewed-by: Peter Ross <[email protected]> Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <[email protected]>
