2019-05-27avcodec/ffv1dec_template: Optimize common case in run modeMichael Niedermayer
Fixes: Timeout (14sec -> 9sec) Fixes: 13398/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_FFV1_fuzzer-5664106709778432 decode_line() becomes 1% faster for fate/vsynth2-ffv1.avi for another fate sample there is a 0.5% speedup the effect should be bigger for files with "flat" colored areas the new faster branch is used in 97-100% of the cases in fate samples compared to the older more complex (which i tested) vsynth3-ffv1-v3-bgr0.avi had the lowest percentual useage of about 97% Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
