[x264-devel] regression test of x264

[Chang Chen]

I use default parameters.

I don't think thread encoding can cause randomness, if so, that should
be an issue.

I guess that spec allow randomness, right?


What's the regression test of x264?

Thanks 
Chang

The only source of randomness that I know of in x264 is if you use
threaded encoding.
I can only guess, since you didn't provide the encoding options that you
used.
