There is an element already (v4l2transform), though it currently only
handle color conversion. I'd like to see scaling in that too instead of
having a separate element that only do scaling like:
https://bugzilla.gnome.org/show_bug.cgi?id=726104
I think Michael and Philipp idea was that scaling could be done directly
out of the decoder, something supported by CODA driver. There is some
work require to get that in GStreamer, see:
https://bugzilla.gnome.org/show_bug.cgi?id=733827 (pixel format nego)
https://bugzilla.gnome.org/show_bug.cgi?id=733828 (display size nego)
cheers,
Nicolas
