2017-01-22avcodec/error_resilience: Optimize motion recovery code by using blcok listsMichael Niedermayer
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>

2015-01-27error_resilience: move the MECmpContext initialization into ER codeAnton Khirnov
Currently, it needs to be initialized by the ER caller (which is currently either a mpegvideo decoder or h264dec). However, since none of those decoders use MECmpContext for anything except ER, it makes more sense to handle it purely inside ER.

This is done to disentangle ER from mpegvideo. In order to use a classic Picture, callers can use ff_mpeg_set_erpic() or use a custom function to set the fields. Please note that buffers need to be allocated before calling ff_er_frame_end().
