bwlp/qemu.git/vnc-encoding-zlib.c, branch spice_video_codecsExperimental fork of QEMU with video encoding patcheshttps://git.openslx.org/bwlp/qemu.git/atom/vnc-encoding-zlib.c?h=spice_video_codecs2010-07-26T22:35:54+00:00ui: move all ui components in ui/2010-07-26T22:35:54+00:00Corentin Chary2010-07-07T18:57:52+00:00urn:sha1:3e230dd23b750f19a2fb95cf08250c74432ed164
Move sdl, vnc, curses and cocoa UI into ui/ to cleanup
the root directory. Also remove some unnecessary explicit
targets from Makefile.

vnc: add basic tight support2010-06-01T17:53:09+00:00Corentin Chary2010-05-19T07:24:10+00:00urn:sha1:380282b07dcc262f011aa665972dacba5d2178bc
Add support for tight encoding [1]. This patch only add support
for "basic" tight compression without any filter.

vnc: return the number of rectangles2010-06-01T17:53:09+00:00Corentin Chary2010-05-19T07:24:09+00:00urn:sha1:a885211eed4e853c64d1419a0113c12048ecd5a1
Some encodings like tight supports tiling (spliting in
multiple sub-rectangles). So we needed a way to tell
vnc_update_client() how much rectangles are in the buffer.
zlib, raw and hextile always send a full rectangle.

Makes sure we free all ressources used in zlib encoding (zlib stream
and buffer).

vnc: don't clear zlib stream on set_encoding2010-06-01T17:53:09+00:00Corentin Chary2010-05-19T07:24:06+00:00urn:sha1:78c98c78705452e439f5b2ef5447ada23de9988e
On init, values are already NULL, but we shouldn't try
to reset them each time a client send a set encoding
command because this break everything. For example,
libvncclient re-send a set encoding command if the
framebuffer is resized.
This fix framebuffer resizing for zlib encoding.

vnc: only use a single zlib stream2010-06-01T17:53:09+00:00Corentin Chary2010-05-19T07:24:04+00:00urn:sha1:b05ad290e2a5d9074179fede31d54371e1a09a6a
According to http://tigervnc.org/cgi-bin/rfbproto#zlib-encoding
zlib encoding only uses a single stream. Current implementation defines
4 streams but only uses the first one. Remove them and only use a single
stream.

vnc: split encoding in specific files2010-05-03T17:09:47+00:00Corentin Chary2010-05-03T12:31:34+00:00urn:sha1:70a4568fe0c5a64adaa3da5030b7109e5199e692
This will allow to implement new encodings (tight, zrle, ..)
in a cleaner way. This may hurt performances, because some
functions like vnc_convert_pixel are not static anymore, but
should not be a problem with gcc 4.5 and the new -flto.
