[FFmpeg-devel] [PATCH] tools/target_dec_fuzzer: Increase maxpixels threshold for dirac

[Michael Niedermayer]

wavelets allow significant size expansion and they are also not
very fast.

Fixes: Timeout
Fixes: 16480/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_DIRAC_fuzzer-5659892689403904 (108sec -> 17ms)
Fixes: 16480/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_DIRAC_fuzzer-5749422717140992 (big ->15sec)
