Description
Summary of the bug:
How to reproduce:
% ./ffmpeg -y -f lavfi -i testsrc2=duration=5:size=qcif -c:v vc2 borked-vc2.avi ffmpeg version N-95880-gd07d1c1dd0-tessus (git master) built on Mon Nov 25 22:33:07 EST 2019
produces a broken sample.
Compared to:
% ./ffmpeg -y -f lavfi -i testsrc2=duration=5:size=cif -c:v vc2 working-vc2.avi
which looks fine.
It seems like VC2 encoding (for 4:2:0 at least) is only working for inputs whose width is a multiple of 64.
