I want to record this stream in my local storage as well as my backend server.

I've done a lot of experiments and here is what I found so far.

First, there are two sets of variables that I tweaked a lot during these experiments:

(1) Rendering Size. Namely the size of SurfaceViewRenderer. This is defined in activity_call.xml and default to "wrap_content", which is the size of the display device. In my case, this is a 27 inch monitor.
(2) Capturing Size. Pass to PeerConnectionClient.PeerConnectionParameters. Default to 1280 x 720.

When starting the call, the stream will be captured and flown into a sink view which at this point is the main view, being rendered in Rendering Size.

The frame rate at this moment is about

_Capturing Size_	_Rendering Size_		FPS
1280 x 720		1280 x 720			9
640 x 360		Full Screen			9
1280 x 720		Full Screen			3
1920 x 1080		Full Screen			1

Note this is purely local. No call has been even made. What is shown is what is captured and sent out directly from the local camera. The whole scenario has nothing to do with the network.

NOTES:
(1) I am using the Raspberry PI camera V1.2. I also tried a USB web cam and the result is about the same.
(2) I even increased GPU memory from 256 MB to 512 MB (config.txt). No effect.
(3) The same device, when running Raspbian, has no problem running a simple Python application using picamera module. The app simply opens preview mode and renders local camera in high resolution at full screen. I don't have an exact FPS number. But it is so smooth that by my estimate is it's easily 24 FPS.

Hi, Guys

I downloaded this and gave it a try on Android studio . using pixel 2 phone simulator.

E/RoomRTCClient: Room connection error: HTTP POST to https://appr.tc/join/FJWNRJM error: Chain validation failed
E/WSRTCClient: HTTP POST to https://appr.tc/join/FJWNRJM error: Chain validation failed

It seems that the issue is related to the SSL certificate, but not sure how to fix it.

Thanks
Jeff

Please update the code, because the RTC library hasn't the VideoTrack class.

I used your demo,But the following two lines are reported incorrectly.

remoteProxyRenderer.setTarget(isSwappedFeeds ? pipRenderer : fullscreenRenderer);

Error: Incompatible type: type error in conditional expression
SurfaceViewRenderer cannot be converted to Callbacks

Hello,
is it possible to screencast the desktop screen instead of video.
In other words, instead of biderectionnal video call, I need to make a screen mirroring from windows/linux laptop to android thing or raspberry pi?

Running this code in Ubuntu/Android Studio 4.0.

Starting the video call resulted in a room being created with an ID, however it is quickly followed by an error message that video call using WebRTC has stopped.

After several tries, I get a connection error:
Room IO error: java.io.IOException: non-200 response when requesting TURN server from https://networktraversal.googleapis.com/v1alpha/iceconfig?key=AlzaSyArJnQRd2kEen3RoVrsQOLxP1TnJJ-y8d8:HTTP/1.1 429 Too many requests.

After a few more tries I get a connection to a room (which I can also join from a web browser), however there is an additional connection error "failed to create a new AudioRecord instance".

The Android emulator is not able to display my connecting webcam (Webcam0) even though it is working fine in the web browser.

    factory = new PeerConnectionFactory(options, encoderFactory, decoderFactory);

If I gone SurfaceViewRenderer view in layout. I got log:
CameraStatistics: CameraStatistics: Camera fps: 30.
I assume the cost to render view too much.

After another client connect to room:

Should I upgrade hardware that stronger than Raspberry Pi 3 to make a streaming device?

I am unable to run the app because i am not getting this pacckage.

please help me to resolve my issue.
