Hi Phil,

You add many private unused options to make it "compatible" with a
libx264 command line. This is messy; private options mean what they
are, specific to the encoder.

Still using attachment to prevent word-wrapping.
For video streaming, repeatSPSPPS flag should be set as 1 besides
disableSPSPPS=0, elsewise if running ffmpeg before vlc/ffmpeg, there
will be no video header, decoder can't work properly.

I'll give you answer later. But there's a more urgent fix, I've sent the
patch, only one-line changed.
It's the creation flag of cuCtxCreate, currently is 0(default) which
will cause CPU thread spins when waiting for GPU to return thus decrease
the CPU performance.
Change it to 4(CU_CTX_SCHED_BLOCKING_SYNC) could solve it.

which means autoselect.
