Message-ID: <20230927161019.GB49963@haasn.xyz> (raw)
In-Reply-To: <20230927135617.33952-1-ffmpeg@haasn.xyz>
Context: I compared our implementation against a H.274 reference stream.
Identified this issues as a result.
This is still not bit-exact, we round incorrectly in some cases (~2% of
output pixels are +1 or -1). I'm not sure where we pick up the remaining
error from..
