Yes, more or less.

It does not really worth to split decoding to 2 cpu, as memory is common,
and decoding uses a lots of memory (the bottleneck of video decoding is
memory bandwith, not the cpu).

Currently it's single process/thread app, expect if running with GUI,
because of the GUI gtk part running on different process.

It is planned to be multi-process program, but it won't help you:
input media cache will run in different process, so a slow cdrom or network
won't block playback.

We don't plan to split decoding to multiple threads/processes.
