I'm seeing gst-editing-service whether h/w elements can be used in GES or not. The answer seems to NO yet. Because video editing can require system resource a lot, I believe h/w acceleration must be very useful.

To support such elements,

• autoplugging scenarios should be considered
• Need a way to selecting filter elements by user such as custom h/w accelerated video converter, scaler, mixer, etc.

And there seems to a bit things to do more.
