From 701ad68d0dccd6d409d480435eadbaf689cfad41 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Sun, 20 Nov 2011 15:39:17 +0000 Subject: [PATCH] Increase the default compression level to cater to a broader range of users (bandwidth is often the limiting factor, rather than CPU). Further increases give little returns, so 2 is currently deemed the best tradeoff. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4811 3789f03b-4d11-0410-bbf8-ca57d06f2519 --- common/rfb/ConnParams.cxx | 2 +- common/rfb/TightEncoder.cxx | 3 ++- vncviewer/parameters.cxx | 2 +- 3 files changed, 4 insertions(+), 3 deletions(-) diff --git a/common/rfb/ConnParams.cxx b/common/rfb/ConnParams.cxx index 2f0e275e..ed747523 100644 --- a/common/rfb/ConnParams.cxx +++ b/common/rfb/ConnParams.cxx @@ -35,7 +35,7 @@ ConnParams::ConnParams() supportsDesktopRename(false), supportsLastRect(false), supportsSetDesktopSize(false), supportsFence(false), supportsContinuousUpdates(false), - customCompressLevel(false), compressLevel(6), + customCompressLevel(false), compressLevel(2), noJpeg(false), qualityLevel(-1), fineQualityLevel(-1), subsampling(SUBSAMP_UNDEFINED), name_(0), nEncodings_(0), encodings_(0), diff --git a/common/rfb/TightEncoder.cxx b/common/rfb/TightEncoder.cxx index 1b37c8ad..9be4581e 100644 --- a/common/rfb/TightEncoder.cxx +++ b/common/rfb/TightEncoder.cxx @@ -74,7 +74,8 @@ const TIGHT_CONF TightEncoder::conf[10] = { { 65536, 2048, 24, 9, 9, 7, 64, 96, 92, SUBSAMP_NONE }, // 8 { 65536, 2048, 32, 9, 9, 9, 96, 96,100, SUBSAMP_NONE } // 9 }; -const int TightEncoder::defaultCompressLevel = 1; + +const int TightEncoder::defaultCompressLevel = 2; // // Including BPP-dependent implementation of the encoder. diff --git a/vncviewer/parameters.cxx b/vncviewer/parameters.cxx index 99b224e6..e8314787 100644 --- a/vncviewer/parameters.cxx +++ b/vncviewer/parameters.cxx @@ -56,7 +56,7 @@ BoolParameter customCompressLevel("CustomCompressLevel", "Default if CompressLevel is specified.", false); IntParameter compressLevel("CompressLevel", "Use specified compression level 0 = Low, 6 = High", - 1); + 2); BoolParameter noJpeg("NoJPEG", "Disable lossy JPEG compression in Tight encoding.", false); -- 2.39.5
