in particular, you are taking a compressed video, sending it over the
network from backend to frontend, uncompressing it to your video card,
compressing it again with vlc, transmitting it over a network,
uncompressing it again to the target machine's video card. Seems a
colossal waste of effort., not to mention downgrade in quality as a
result of the multiple decoding and encoding.
