I am locally using:
    if (bpp == 8 && (flags & AV_CPU_FLAG_RVI)) {
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)) {
So no output, but I think the same modification should be made here?
