[Parti-discuss] jpeg compression

[lars hofhansl]

Hello, 


I have a relatively clean patch to enable JPEG compression for Xpra.
Is there general interest in that? If so, I'll forward a patch against Xpra-current to the list.

The advantages of using jpeg compression are not necessarily obvious.

In my tests I found that for "text only" traffic (emacs, terminals, etc) the message sizes sent over the wire actually *increase*
unless a very low quality (with corresponding bad results) is chosen.

For other traffic like web browsing, the savings are sometimes quite good (reducing traffic by 25-75%). 
For (natural) image intensive application (photo viewer, gimp, etc) traffic is often reduced by as much as 95%.
(Boh depending on the quality chosen. At quality setting 60 the savings are quite good).

Thanks.
