Subject: [FFmpeg-devel] [PATCH] avcodec/nvenc: fix b-frame DTS behavior with fractional framerates
Date: Sun, 2 Apr 2023 15:02:25 -0700
Message-ID: <20230402220225.342600-1-tt2468@irltoolkit.com> (raw)
When using fractional framerates (or any fraction with a numerator != 1),
DTS values for packets would be calculated incorrectly.
