Michael Niedermayer	6d4fdb4f5a	tools/target_dec_fuzzer: Adjust max_pixels for AV_CODEC_ID_HAP Fixes: Timeout (170sec -> 6sec) Fixes: 20956/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_HAP_fuzzer-5713643025203200 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
Michael Niedermayer	d6824ef905	tools/target_dec_fuzzer: Reduce maxpixels for HEVC high resolutions with only small blocks appear to be rather slow with the fuzzer + sanitizers. A solution which makes this run faster is welcome.
