Instructions for 64 bit systems

This is just some extra information when using a 64-bit Linux: for the stream to work with recent versions of Skype (tested with 4.2.0.11), you may need to manually force the 32-bit dynamic library to be used, like this:

LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so skype

This example is for Linux Mint, for other distributions you need to replace the path with the appropriate directory containing the v4l1compat.so (you can use locate v4l1compat.so).

Also, you need to start Skype after having established the video stream, otherwise it may run into an error:

libv4l2: error getting pixformat: Invalid argument

If this happens, it will probably be necessary to exit Skype, start the stream using prepare-videochat.sh, and then start Skype again.
