Message-ID: <CAEa-L+su4qdONZxe6yDifT5Y-ZBFZhcU98Kj2gqJgOXQZqjZFA@mail.gmail.com> (raw)
In-Reply-To: <5092357.BloR0pLUYu@basile.remlab.net>
I am locally using:
if (bpp == 8 && (flags & AV_CPU_FLAG_RVI) && (flags &
AV_CPU_FLAG_RVB_ADDR)) {
this performs better on k230/banana_f3 than C.
For email, refer to [FFmpeg-devel] [PATCH 2/2] lavc/vp8dsp: restrict RVI
optimisations and change it to
if (bpp == 8 && (flags & AV_CPU_FLAG_RV_MISALIGNED) && (flags &
AV_CPU_FLAG_RVB_ADDR)) {
So no output, but I think the same modification should be made here?
