tools/target_dec_fuzzer: Stop negative block_align and sampling rate These are checked for early in avcodec_open2() and do not really test the decoder but instead waste resources which could be better spend fuzzing the actual decoder Signed-off-by: Michael Niedermayer <mich...@niedermayer.cc> > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=c1411a1132595bddbca254322d85bfe24b038536 --- tools/target_dec_fuzzer.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tools/target_dec_fuzzer.c b/tools/target_dec_fuzzer.c index c232f6d41a..2d9d28b46d 100644 --- a/tools/target_dec_fuzzer.c +++ b/tools/target_dec_fuzzer.c @@ -206,9 +206,9 @@ int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) { extradata_size = bytestream2_get_le32(&gbc); - ctx->sample_rate = bytestream2_get_le32(&gbc); + ctx->sample_rate = bytestream2_get_le32(&gbc) & 0x7FFFFFFF; ctx->channels = (unsigned)bytestream2_get_le32(&gbc) % FF_SANE_NB_CHANNELS; - ctx->block_align = bytestream2_get_le32(&gbc); + ctx->block_align = bytestream2_get_le32(&gbc) & 0x7FFFFFFF; ctx->codec_tag = bytestream2_get_le32(&gbc); keyframes = bytestream2_get_le64(&gbc); ctx->request_channel_layout = bytestream2_get_le64(&gbc); _______________________________________________ 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".
