tools/target_dec_fuzzer: limit per frame samples for APE APE in its highest compression mode is really slow so even one frame of millions of samples takes a long time Fixes: Timeout (too long -> 3sec) Fixes: 19937/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_APE_fuzzer-5751668818051072 Signed-off-by: Michael Niedermayer <mich...@niedermayer.cc> > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=32522b530779e155001b1a45e764d8185aa189e1 --- tools/target_dec_fuzzer.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/tools/target_dec_fuzzer.c b/tools/target_dec_fuzzer.c index 752df43a64..2487b6ca94 100644 --- a/tools/target_dec_fuzzer.c +++ b/tools/target_dec_fuzzer.c @@ -93,7 +93,7 @@ const uint32_t maxiteration = 8096; const uint64_t maxpixels_per_frame = 4096 * 4096; uint64_t maxpixels; -const uint64_t maxsamples_per_frame = 256*1024*32; +uint64_t maxsamples_per_frame = 256*1024*32; uint64_t maxsamples; static const uint64_t FUZZ_TAG = 0x4741542D5A5A5546ULL; @@ -133,6 +133,9 @@ int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) { case AVMEDIA_TYPE_VIDEO : decode_handler = avcodec_decode_video2; break; case AVMEDIA_TYPE_SUBTITLE: decode_handler = subtitle_handler ; break; } + switch (c->id) { + case AV_CODEC_ID_APE: maxsamples_per_frame /= 256; break; + } maxpixels = maxpixels_per_frame * maxiteration; maxsamples = maxsamples_per_frame * maxiteration; switch (c->id) { _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email ffmpeg-cvslog-requ...@ffmpeg.org with subject "unsubscribe".
