The author of TurboVNC conducted a study (2014) on using H.264: https://turbovnc.org/About/H264

self hostable alternative, F*EX and the sex command : http://fex.rus.uni-stuttgart.de/

Is it ? Is it doing pipes ? because I see only file transfers there which is not exactly the same as you loose the realtime / streaming factor.

Search for "stream" on the homepage : http://fex.rus.uni-stuttgart.de/SEX.html

ha ok, cool

Checked - really cool set of features implemented with simple, usable and elegant workflow in mind [though not a Perl fan]!

I'm not a Perl addict neither, but I'm using FEX in production and it worked flawlessly for more than a year now and hundreds of users.

Easy to install (inetd/xinetd), easy to upgrade, self cleaning, nice behaviour when you reach the limit, the command line tool are autonomous (just put them in your PATH), the developper is (very) reactive. It just works.

It is as efficient as the website is old-school =) I'm an enthousiastic FEX administrator and user !
