WebRTC not showing video
I have webclient that uses WebRTC from javascript and UWP client that is using WebRTC from NuGet.
When I run UWP client on desktop, I can see video stream and audio on webclient.
BUT when I use the same code from UWP desktop client on HoloLens app, I only get audio.
Has anyone encountered the same problem?

@JackStones could you share your code please?
Have a look at this sample:
https://github.com/webrtc-uwp/PeerCC/tree/dec1d6daf812fee5b863b2e6949e3c588d90cb9b
It is complete, and the conductor class is highly reusable.
You have only to adapt your signaling mechanism.5

Working on a similar project and having some issues establishing connection between the UWP client and a web (javascript) client.
Could you share your code?
unfortunately, I cannot share my code (it is not up to me), but I did everything in C# code that is similar to javascript code and my UWP desktop app is working (from UWP I only send video and audio, and I never implemented how to show received video). UWP desktop can send video feed to web client. problem comes when I use that code on hololens because only audio is working on web client but video is never shown. (I am still new to webrtc, and believe that there is something wrong with candidates for video - please note that I could be wrong)
I did it!
Last night, after many hours of headache i got my webrtc audio/video stream from hololens to a web client.
Actually it only works in one direction (hololens to webclient) in a LAN environment. Next step will be the enabling of bidirectional stream and the introduction of STUN/TUN servers.
All the issues i encountered were relative to signalling communication offer/answer/candidates. Keep attenction expecially to serialization/deserialization of exchanged data.
Have you encountered problem where audio is received on webclient, but video is not?
In my case nothing was streaming because of error in the candiates adding.
@Xarthisius I believe I have the same problem.
1) When I set video=true and audio=true, ONLY audio from webclient is transmited to hololens
2)When I set video=false and audio=true, then I receive audio from webclient to hololens and from hololens to webclient
Both devices are on LAN.
Did you manage to solve video problem?

I didn't use this code in hololens app, but it did help me to modify my own code to make video work. Thanks
Glad to listen the sample was useful.
I have a question for you: i'm able to send webrtc audio/video to a webclient but now i need to do the opposite too.
Have you any idea on how to implement this feature?
Is there any way to use the webrtc stream as a texture in unity?
Hi , i am also interested in streaming form the Hololens from inside my Unity app to a desktop. How did you get the video/audio feed in the first place. The unity webcam texture gives very low fps on the device.
Thanks
I'm not sure to understand what are you asking for.
I'm using webrtc for the audio/video streaming through the UWP wrapper.
Sorry, i mean do you use the Unity 3D game engine? If yes how did you get the initial video/audio data to send over with webrtc?
Thanks
No. Actually i have a UWP 2d application. Now i'm going to port the code under Unity 3d and trying to figure out how to show the stream on a texture. That is the question i posted before.
Cool, keep me posted if you achieve that. I am trying the same thing now.
If i come up with something i will let you know.
I suppose (reading other posts of yours) you're trying to get the MRC (mixed reality capture).
I indeed only need to show the pure video streaming.
I never intended to show video feed in hololens app, but I am curious on how to achieve that. Currently I don't have time for that, but if I do it in the future, I will make a comment about it.
