Synchronized streaming to iPads

[jgdye]

I'm wanting to use a spare Raspberry Pi 3B to essentially act as a vehicle entertainment center for our children. We've been pulling the same video up on a pair of iPads and carefully hitting start at the same time on both to reasonably synchronize the two, and playing the audio over the van's bluetooth. I recently had a separate project fall through, and thought I'd try to use the Pi to create essentially a live stream that would keep us from having to fiddle around to synchronize the two iPads. I'd like to find software that can create a stream that can be viewed specifically on the iPad, and would be reasonably synchronized on both clients (I don't need perfect, but something that doesn't look more out of sync than a dubbed movie would be ideal), using the Pi to both host the stream and act as the wifi access point to distribute it to the clients. I don't have a large backlog of videos that would require transcoding, so I'm not wedded to any particular encoding, just one that is reasonably supported on iPad, and am willing to install App Store hosted apps if necessary. I've tried searching for this, but haven't figured out the right combination of search terms and keep getting results for generating a stream on the iPad or using the Pi as a media server where the streams to the clients wouldn't be synchronized. Are there any good starting points for accomplishing this?

VLC, perhaps?
I haven’t used the app in a long time but I think it can open an RSTP stream.
vlc-cli on the Pi should be able to produce a stream.
