When we have issues capturing a presentation due to hardware failure, but audio has been captured, we advise staff to attach their presentation to the class so students can still make use of the recording. We have discovered this presentation is not accessible when the recording is then embedded. We remove the broken video input, so there is only 1 video channel (webcam) and when viewed in the class list, this then shows the presentation alongside the webcam. In the embedded video, only the video input is played and not the presentation. We would like an option in the overlay to show the presentation, so a) viewers are aware there is an attached presentation b) viewers can toggle the presentation to be viewed alongside the recording in a similar way to how it is viewed in the class list.
