Hi,
Since v2:
- Fixed some styles issues
- Rebased to current master
- Fixed a Makefile issue (using .c instead of .o)
I rebased the series against current master, it contains:
- Adaptive Tight Encoding: send lossy or lossless updates depending on the
update frequency of the screen region. If a lossy update is forced, then
it will be refreshed with a lossless update as soon as the update frequency
goes back to 0.
- ZRLE/ZYWRLE Encodings: ZYWRLE use less bandwidth than tight, but the result
is also probably more lossy. I wanted to make ZRLE/ZYWRLE adaptive, but this
is not possible because most of the vnc clients can't switch between ZRLE and
ZYWRLE. But a possible solution is to use another encoding for lossless
updates,
like zlib or tight.
- Bitmap module: create bitmap.h and bitops.h, and remove duplicate code
from vnc.c
It was my last series from GSoC 2010 context, if necessary I can send different
series for adaptive vnc, zrle and bitmap stuff.
Thanks,
Corentin Chary (16):
vnc: qemu can die if the client is disconnected while updating screen
vnc: don't set the quality if lossy encoding are disabled
vnc: add a way to get the update frequency for a given region
vnc: refresh lossy rect after a given timeout
vnc: tight: use the update frequency to choose between lossy and
lossless
vnc: palette: use a pool to reduce memory allocations
vnc: palette: add palette_init calls
vnc: palette: and fill and color calls.
vnc: Add ZRLE and ZYWRLE encodings.
vnc: fix uint8_t comparisons with negative values
vnc: fix lossy rect refreshing
bitmap: add a generic bitmap and bitops library
vnc: use the new generic bitmap functions
vnc: don't try to send bigger updates that client height
vnc: tight: tweak adaptive tight settings
vnc: add a non-adaptive option
