If you build with lz4 enabled (both client and server),
then it should use lz4 to compress the data.

There is no functionality to create
a video stream out of raw data.

Can the USB camera be configured to send a compress stream?


   USB camera can support MJPG and YUV.   I think H264 is better than MJPG. So Can we 
let spice support H264 ? Is this feasible? 

Thank you
