starting RV from inside a maya 2011 using an RV version greater than 3.6.9 (actually I tried with all the 3.8 and 3.10 versions we have)
Rv starts but crashes without showing anythingimport os
import subprocess
launchCommand="/opt/tweak/rv/3.10.8-x64/bin/rv"
scene="myscene.@@@@.png"
subprocess.Popen([launchCommand,scene],shell=False)
NOTE:
All the versions 3.6.9 to 3.10.8 work perfect under maya 2008
only 3.6.9 work with maya2011

An answer was found:
The problem was that upon start maya2011 sets LIBQUICKTIME_PLUGIN_DIR to point to a maya directory, and this is not compatible with RV so a symbol clash occurs and maya crashes and exit.
as per tweak support, RV does set the LIBQUICKTIME_PLUGIN_DIR variable internally but only if it's not set already.
So the solution is to either totally unset the variable or point it to the rv plugins/libquicktime directory, and restore the old directory after the execution
import subprocess
RV_LOCATION="/opt/tweak/rv/3.10.8-x64"
launchCommand="%sbin/rv"%RV_LOCATION
scene="myscene.@@@@.png"oldPluginPath=os.environ[LIBQUICKTIME_PLUGIN_DIR]
os.environ[LIBQUICKTIME_PLUGIN_DIR]='%s/plugins/libquicktime'%RV_LOCATIONsubprocess.Popen([launchCommand,scene],shell=False)
os.environ[LIBQUICKTIME_PLUGIN_DIR]=oldPluginPath
the other way will be to unset the variable, so instead of re-setting to the rv plugins/libquicktime directory , you can do
os.environ.pop('LIBQUICKTIME_PLUGIN_DIR')
and then if this variable is not set at all then rv will set it internally
