[Spice-devel] spice 0.12.4 and qemu 2.0.0 : bad video perfomance

[nicolas prochazka]

Hello,
thanks to point this .

with <streaming mode='filter'/>   : video is ok , qemu 2.0.0 manpage
does not reflect the default streaming mode ( off)
with qemu 2.0.0 , i need to setup  <playback compression='off' />  ,
without the sound is very bad , not in with qemu 1.7.1 , is it a
default parameter change ?

Regards,
Nicolas Prochazka.
