I have wrote this little script according the instructions suggested by @suli8.

If you save it to a file (lets call it apply-googletalk-v4l1-workaround.sh, but can be anything), then you could apply it by:

sudo bash apply-googletalk-v4l1-workaround.sh

This might help in avoiding small mistakes.

#!/bin/bash



plugin_location=/opt/google/talkplugin/GoogleTalkPlugin



mv $plugin_location $plugin_location.real



cat > $plugin_location <<EOF

#!/bin/sh

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so $plugin_location.real

EOF



chmod +x $plugin_location



killall GoogleTalkPlugin

I have seen in an above comment that the workaround made Google Talk stop working in Gmail. I guess it was because of some small error in executing the steps. Using this script might avoid that error.
