Hello, it seems like Apple's HEVC stereo video metadata parsing is already supported. Is there a plan to add multiview extension to HEVC for full stereo video decoding?

courmisch: rpi5 has dotprod, thanks for the hint!
<sdc>
what are the benefits of testing on an in-order ARM cpu? is it just that there's a lot of in-order ones in the wild?
<Lynne>
it helps you see exactly what impact your changes have, with zero noise
<Lynne>
you get single-cycle accurate results every time

<ramiro>
Lynne: now I end up with one implementation that's faster for the rpi3, and another that's faster for the rpi5... I don't suppose we can detect at runtime if it's in-order or not.

draw_edges_mmx is much slower than the c version for large images
<ramiro>
and draw_edges_8_c can be easily made faster by av_always_inline'ing the function for hardcoded values of w as 4, 8, and 16.
