How can I install pepper plugin into chromium that is running from compiled src/out/ directory?
I found the answer here http://www.chromium.org/developers/design-documents/pepper-plugin-implementation
out/Release/chrome --ppapi-flash-path=/opt/google/chrome/PepperFlash/libpepflashplayer.so --ppapi-flash-version=`grep -i version /opt/google/chrome/PepperFlash/manifest.json | awk '{print $2}' | awk -F"\"" '{print $2}'`
did the trick.
