Hello HN, Lot of educators are now teaching remotely but the most favourite tool of a teacher, whiteboard/blackboard is missing from their teaching arsenal

To project their physics experiments, chemistry labs, even good old pen & paper live

We built a p2p way to stream any smartphone camera to a browser while they are streaming their screeen live to students on zoom, google meet etc

Please do checkout and leave your valuble feedback. https://show.veda.ai/

Thanks, just to clarify: your servers are only used for the handshake here and the video is kept completely local right?

PS: https://show.veda.ai/demo.jpg I hate how accurate this picture reflects parts of my improvised setup. :)

Yes, our servers are only for signalling.

Nice, we wanted to show the bare minimum required to use the tool.

This worked fine when I first used it, but now it asks for audio/microphone permissions even though in my father's use case he is just using the video aspect and then using Zoom for the audio/video with his students.

Can you push a fix to not require all three permissions to work?

Hi, this sounds really usefl and wanted to give it a try, but the connection hanged while trying to connect. I was able to scan the URL in my phone and open the browser (Firefox Nightly), but couldn't see it in action. My phone was stuck in "Peer Created", while desktop (Firefox Developer Edition) was at "Reconnecting!". Is it a network problem on my side?

Hello, I'm a developer behind it. Can you tell us which OS you are on in both phone and desktop? And does both the devices are on same network?

Sorry for the delay. I'm on Android (phone) and Windows (desktop). At the moment of the test I was in the same network I think.

Hello fellow hacker, we tried a lot of hit this issue before sending this message but couldn't.

Can you pls try again making sure both are same network. We have made a conscious decision not to use a TURN server as we don't want any traffic to go via us.

I have the same issue with Firefox on Windows :). How can I help you in reproducing it?

Awesome idea, but I can't seem to make it work. See both mobile and desktop screenshots here: https://imgur.com/a/LnM2Uej (Safari on both iOS 13 and macOS 10.15)

Thank you for the detailed logs,Can you please confirm if both the devices are on same local network?

They are.

Safari on iOS 13 is working with Chrome on macOS now.

Perhaps you are using a mesh wi fi extender?

I'm not.

Thank you for the reply, we are trying to replicate the issue but due to lockdown in our country we couldn't procure few things to test from iOS and Mac safari, pardon the delay we will update you soon.

I have the same issue with Firefox on a Windows machine. My phone is iOS.

iOS Safari and Windows Firefox is working

What benefit does this have over a cheaply USB webcam and OBS with the obs-virtualcam plugin?

Hello fellow hacker that was the first thought we even thought to provide a camera source like snapcam and others do but we wanted to keep it simple and take a zero installation approach this is output we got.

An interesting tidbit, on javascript side even if we are paying a video, we expect phones to not turn off display but some phones still turn off the display. This was one scenerio when we thought app would be appropriate

Realistically do most people even have separate webcams at home?

I know I don't, but there's at least 5 smartphones somewhere in the house. Harnessing those cameras via wifi is pretty useful.

I don't have a separate webcam, but I use my Pixel 2 as an OBS webcam with DroidCamX with much better quality that a fancy $200 Logitech webcam. There is a similar app for iOS. Even better, you can use multiple phones for different angles or to point to a notepad.

Can we save the recording?

We sure can do it technologically and i imagine you want something like project Haven.

But considering the usecase of streaming for teaching, like other comment mentioned there are other ways to do it and if there are more requests for this, we would be happy to add

I believe the intention is to have the window on the screen then you use screen sharing to share it. So if you're using zoom or obs or another tool, then you can record it while streaming it
