It appears - from looking at the sources - that ffmpeg's libx264
integration lets libx264 use ffmpeg's logging functions (by a so-called
callback). Therefore, libx264's log outputs land in ffmpeg's log.

This does not seem to be the case for libx265 - either because the
library does not supply these hooks, or ffmpeg doesn't use them. So
libx265 probably outputs that information to stdout/stderr by its own
