I’d like to be able to share the video feed live on site to a bunch of students who will have mobile phones on them. Otherwise, not all of them can crowd around the PC screen we use to control the ROV. Note, we don’t want to be able to control the PC from the phones - we just need to broadcast the ROV feed to the phones.
To avoid tether bandwidth issues you’ll need something at the topside to relay the video from the vehicle to the other devices. If you have available stable wifi then the simplest solution would likely be to install Open Broadcast Studio (OBS) on the topside computer, and stream the video to Twitch or some other streaming service, which the students can then watch on their devices in situ or remotely.
If things need to be handled locally (e.g. if there’s no internet available at the testing site) then it’s more complicated, because the video needs to be converted to a form that the mobiles can readily consume and display.
