This is independent from SPICE, if the camera send compressed data<br>
already SPICE will just<br>
forward compressed data in whatever format is in USB.<br>
If the camera supports MJPEG and YUV choose MJPEG, YUV is not<br>
compressed (just a different color<br>
space than RGB, often taking less bits but still not compressed).<br>
