Re: UV4L Server on outside of raspberry pi

Deploy the Janus Gateway in your server instead. UV4L supports Janus Videorooms. This should be:

RPI/UV4L <-> Janus Gateway <-> Web Browers.

I did configure the function start() at this line from:
ws = new WebSocket(protocol + '//' + server + '/stream/webrtc');
into:
ws = new WebSocket(protocol + '//' + server);
With that change probably you need to set server-option = --www-webrtc-signaling-path=/

Where can I have a look / modify the cipher suite my Rpi is using? (I have Jessie) The choosen cipher depends on the client...

Re: Getting the most out of your V2 camera with UV4L.

How is it that you were able to remove the "software by http://linux.project.org" watermark from the video? There is no watermark for what the OP is doing. The watermark is only present when using some peculiar features of the Streaming Server like WebRTC and can be disabled for free - contact the ...

Re: Feed the camera a video file

Is it possible to feed the camera a video from a local file ? i.e. make the camera "see" a custom video file instead of the actual capture? This is for testing purposes Maybe not from a file directly (yet), but UV4L provides a number of V4L2-compliant drivers for various virtual (or real) devices w...

Hi !
I want to implement an android app that can connect with the uv4l-WebRTC extension.
What application do you have in mind, a web application that you can run in the Android browser or a "native" WebRTC application (e.g. in C++ / Qt)?

black? You might need to skip the first frames? Check if you get any video from the streaming server web page in the first place.

Re: CPU loading with UV4L (WebRTC)

Set the memory split to 128M in raspi-config and retry to see if it still hangs. With audio processing it takes more CPU, that's expected.

Yes I'm going to the WebRTC page:

https://192.168.0.101:8080/stream/webrtc
then there is a checkbox to force the use of the H264 hardware encoder which should keep the CPU load at minimum.
