* avcodec/error_resilience: Optimize motion recovery code by using blcok listsMichael Niedermayer2017-01-22
| | | | | | | | | | | | This makes the code 7 times faster with the testcase from libfuzzer and should reduce the amount of timeouts we hit in automated fuzzing. (for example 438/fuzz-2-ffmpeg_VIDEO_AV_CODEC_ID_RV40_fuzzer) The code is also faster with more realistic input though the difference is small here as that is far from the worst cases the fuzzers pick out Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/targets/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
