Going one e-mail further back:

Did you use the *identical* input file in both environments (the
successfull and the failing env)?

Did you use the identical ffmpeg binary in both environments? E.g. the
ffmpeg-4.0.2-static johnvansickle.com build, or your N-91639-g85c0064

If so:
I don't know if it's relevant for this behavior of the h264 decoder,
but can you try restricting the number of threads to one with
"-threads 1"?

I can't see why the decoder should throw
> [h264 @ 0x65c2fc0] concealing 2628 DC, 2628 AC, 2628 MV errors in P frame 
on one platform, but not another, unless you have issues physically
reading the input file.
