From d6824ef905e0c30485e112858de1ab761fcb01d0 Mon Sep 17 00:00:00 2001 From: Michael Niedermayer Date: Sun, 19 Apr 2020 23:54:08 +0200 Subject: [PATCH] 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.
