Yes, that most likely is the problem. But in order for us to fix it, we'd need
your help to figure out exactly what the problem is so that we can reproduce
it. Can you try decoding with framecrc to see if that works correctly, or if
the problem is elsewhere. We'd like to know if the problem is with the
decoding, or with swscale, or with some other component. (Do you convert the
data from YUVA to RGBA after decoding, before blending?) Can you provide the
full application that shows the problem, or a small example that does it, so
that we can reproduce and analyze the problem ourselves?
