Didn't have tried, but why do we want view a video in proxmox console ?
Isn't it mainly for administrative tasks ?
I'm not sure vnc protocol is fast enough for true video rendering.
spice should be better for this task.(in vdi environnement)
>>AFAIK the jpeg compression is far better?
but jpeg is not a vnc protocol ? (but is used inside these prococol)
Like Zlib encoding, Tight encoding uses zlib library to compress the pixel data, but it pre-processes data to maximize compression ratios, and to minimize CPU usage on compression. Also, JPEG compression may be used to encode color-rich screen areas (see the description of -quality and -nojpeg options above). Tight encoding is usually the best choice for low-bandwidth network environments (e.g. slow modem connections)."

Does it work when you view a video from youtube.com?

AFAIK the jpeg compression is far better?
