[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 again Xpra current to the list.

The advantages of using optional 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 a corresponding bad image) is chosen.

For other traffic like webbrowsing, the gain is sometime quite dramatic (reducing traffic sometime by 50-70%). 
For image intensive application (photo viewer, gimp, etc) traffic often reduced by as much as 95%.
(Boh depending on the quality chosen. At quality setting 60 the savings are quite dramatic).

Thanks.
