* Further optimizations to the Tight encoder to eliminate getImage() overhead. ↵DRC2011-08-171-1/+1
| | | | | | The encoder now directly accesses the framebuffer for solid rectangle computation, JPEG encoding, and color counting (if pixel translation is not required.) Also moved everything in tightEncode.h into the TightEncoder class to eliminate all of the static mess (this will be important later on if we decide to multi-thread the encoder.) git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4631 3789f03b-4d11-0410-bbf8-ca57d06f2519

| | | | | | parameters were determined through extensive low-level profiling (see http://www.virtualgl.org/pmwiki/uploads/About/turbototiger.pdf). The other enhancements involved: (1) porting the solid subrectangle pre-computation code from TightVNC/TurboVNC (it makes a pretty big difference-- see report), (2) encapsulating the JPEG encoder in its own class (this eliminates a buffer copy, and the JPEG buffer is now set to a decent size where it shouldn't ever need to be paged or re-allocated, except in rare corner cases), (3) adding support for last rect. encoding (necessary to support the solid rectangle pre-computation enhancements. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4626 3789f03b-4d11-0410-bbf8-ca57d06f2519
* Remove the "video" feature and its associated custom JPEG handling.Pierre Ossman2009-03-051-82/+0
| | | | | | | | Having the client specifiy the video region is conceptually wrong and a problem like this should be handled by better encoding selection. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@3635 3789f03b-4d11-0410-bbf8-ca57d06f2519
