Once this one is in I'll prepare the patch that actually enables

Just remember that the current patch does not make all h264

o It must be encoded with multiple slices

o in-loop filtering must be disabled across slices (or
disabled entirely)

To verify this turn on FF_DEBUG_PICT_INFO and look for the

slice:# ... loop:#:#:#  -debug line

The number of slices will yield the maximum concurrency
level you can achieve.

The first digit after 'loop' must be 0 or 2
