>Blow is the debug message and I added lots of FIXME message:

Added? most of those look like messages that already exist and can be printed
with GST_DEBUG=gl*:5

It seems like you're trying to run gst-plugins-gl in a virtual machine.

That's telling you that your driver doesn't support framebuffer objects which
are required for upload (or there's a bug in the extension getting code).

What does running glxinfo | grep framebuffer in the VM produce?
