?

Can you reproduce the following issue that I see here?
When testing with ffplay, in ~50% of tries, videos look fine,
in other cases, I get a monochrome unchanging image
and the following repeated error message:
[mpeg4 @ 0x7fbba8076200] concealing 8159 DC, 8159 AC, 8159 MV errors in I frame
(race condition?)

Additionally, for the SR422 sample, I get the following warning:
DPCM encoded block is not implemented
