I was in touch with Jon Nordby (who wrote it in the first place) and he thinks it's because I was using the older pyGTK bindings rather than pygobject- pycairo doesn't use gobject, it uses its own wrapper, which explains it.<br>



<br>
So, I'm trying to get it to work in GStreamer 1.0, which Jon suggested- however, it doesn't seem to <i>have</i> cairooverlay, even though I've installed gstreamer1.0-plugins-good from the developers ppa (on Ubuntu 12.04), it seems to be there <a href="http://cgit.freedesktop.org/gstreamer/gst-plugins-good/tree/ext/cairo?h=0.11" target="_blank" rel="nofollow" link="external">in the source</a>, but gst-inspect-overlay0.10 doesn't list cairooverlay, or indeed cairo-anything. I poked around the .deb and it does not appear to be there but I'm not very familiar with the structure of .deb packages. I guess the deb might be slightly out of juncture?<br>

<br>(Also, gstreamer was complaining about the jack audio server not being installed- I installed the package from the Ubuntu main repo and started jackd myself and it worked, but it ought to be a dependency resolved by the gstreamer package, right?)<br>
