The problem of video compression is primarily numerics-limited, there
is nothing an OS can change here. The latency and bandwidth of the
Internet is so bad that the OS overhead is invisible. As to parallel
DSP boxes, for that particular application you don't need an OS at
all, or a very skeletal one. There is a number of minimal DSP OSSes
out there, particularly for TI's chips. It is not very hard writing
these.
Btw, a related idea: a few days ago some friends of mine asked me
whether a modern video accelerator could be useful for neural DSP (as
you know, you could use several in a PCI system). I am aware that
next-generation video chips will feature VLIW DSPs with
multiple GOPs, but do _current_ video accelerators qualify? I had the
impression that these things were pretty special-purpose...
