Thanks for the information, Yoann! It got me quite a bit further. With the
single-thread rendering loop, present is called. However it seems that also
start and stop is called for each single frame as well. Anyway I understand
this is work-in-progress.

When the rest is implemented so that it works like any other media backend,
I would not have minded having the option to get the raw
GL_TEXTURE_EXTERNAL_OES, rendering it with a specialized shader etc, to
save the extra step via an FBO. Maybe it could be indicated with the custom
video surface class that it would accept such a texture format, somehow.
