Option to disable webcam video and centre slides

[aukondk]

I have many videos where the speaker has disabled the webcam feed so we just get a white box. I have tried setting webcam-size to 0 and that does hide it but the slides are still on the left side of the video rather than centred.

I used --webcam-size=0 for one of the cases where we had a remote presenter who didn't turn on his camera. His slides were wide screen formatted though, so things worked out.

If you've got a presenter who used slides in some other aspect ratio, could you also use the --height and --width options to set the final video aspect ratio to match?

I might give that a try next time. The one I tried the size 0 on wasn't 16:9 so others might do better. I have a big batch of videos processing and some have so many annotations that it will be quicker to just crop the final video with ffmpeg.

Your option "--webcam-size=0" works but it would be great if the slides can be centred.
