[Spice-devel] Multithreaded decoding/streaming

[Armin Ranjbar]

Hey! thanks for debugging information, it does really spawn another spicy
process when streaming, but only one, not as many CPU's as i have. any idea
how to increase this?

also to the second part of the question, any ideas where to look for making
non-streaming multi threaded?
