It's the final decode step that can produce two different results.
It is only some that fail.
Sample contains only video.
Decoding the video from mkv is tested and works.
Only setting that seems to make a difference that is used with
that test is -idct simple.
Any idea what could cause it?
Can someone with an affected machine test?
I get CRC=0x037e3e79 when removing -idct simple like this:
