They do not do that by default, because MSAN requires all dependencies to be instrumented too. See https://google.github.io/oss-fuzz/getting-started/new-project-guide/#sanitizers Looking at build.sh for ffmpeg, it should be fine to enable it. Obviously I have not tested everything, but I was running some tests locally with MSAN and also tested it with mpv oss-fuzz builds where we build ffmpeg too with MSAN. - Kacper _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
