Attached fixes "diagonally shifted", but chroma is still moved ~half width.
Note:
See TracTickets
for help on using tickets.
The video is 350x230 but is stored as 352x230 (multiple of 4 width).
Without knowing why that is so (is that always the case for NV12, is it only because it is in AVI or was the program that generated the AVI file broken?) it's not really possible to fix.
