Comment:
Please provide a command line and complete, uncut console output for all
(non-build) reports on this bug tracker!
(You do know that FFmpeg contains a native MPEG-4 ASP encoder that is not
known to be worse than xvid?)
What happens if you (slowly) increase the thread count? With the native
encoders, you have to use a higher thread count than the number of cores
you want to use (same as make -j).
For me, -vcodec libxvid -threads 8 uses many threads, but it significantly
hurts performance over -threads 1.
In case I understood correctly that you are writing down your experience
somewhere:
Please note that 0.7 uses a deprecated syntax that gets outdated, you
should definitely use current git head for tutorials and similar.
