Comment (by Balling):
>Calling back into avcodec (avcodec_receive_frame for example) doesn't
seem to have adverse effects. It even seems to clear the registers
sometimes, although I have not identified the pattern for it yet.
What did you use to compile .dlls? They are 32 bit, are you sure we even
care about 32 bit?

It is corrupt...

Is that inline assembly bug? Why do not you think is not a bug of what you
used to compile .dlls? It appears you used 14.29, which is still Visual
Studio 2019.
