Fix video distorsion when cropping lecture #262

Open fightling opened 4 years ago

fightling commented 4 years ago

At congress we had some video distortion when cutting to lecture. Transitions doesn't seem to have that problem. Seems to be a problem with the gstreamer videobox element.

My first idea was to replace videobox by videocrop but changing properties of videocrop does not seem to work (see voctocore/lib/scene.py)

After talking to Tim-Philipp Müller who is the author of videocrop about that it's not working with GstController which we use for our transitions I opened a bug issue and another one about the video distortion.
