Re: HDMI to CSI-2 TC358743 I2S Audio

- UV4L "black boxes" stuff so that you get a pre-encoded H264 stream, but audio won't work. It's closed source so you're reliant on RpiName who sometimes pops up on here to assist with UV4L. if the audio device is exposed as an alsa/pulseaudio interface by the kernel/os, then it should be possible ...

Re: VNC Retropi

Last time I was working on this, I got as far as just about everything running except I could not control it remotely. I still needed a controller connected to the PI itself. Was there an update that has resolved this or is there a workaround required? See this tutorial: https://www.linux-projects....

Re: Casting RetroPie to laptop display

Does anybody know how I can view my retropie screen, like the menu, games, etc., through VNC? I connected to my pi but i was only able to bring up the terminal but no GUI. I installed VNC using ssh terminal in putty, set the server to :0, and :1, set a password, and cant get anything. Is this possi...

Re: UV4L deletes all /dev/video* and can't pick H.264 stream of the UVC USB camera

Up @RpiName do you know why ffmpeg can take the native H.264 stream of the camera from /dev/video2 and export it as an .MP4 file with the flag -vcodec copy without any issue, but UV4L HTTP streaming server using same system driver V4L2 uvcvideo fails to pick this raw H.264 stream from /dev/video2 (...

Re: UV4L deletes all /dev/video* and can't pick H.264 stream of the UVC USB camera

WTF is that?! This means that when UV4L is running, I can no longer access the other streams with ffmpeg at all, or any other software for that matter. Even worse, from /dev/video4 UV4L decides to point to the 1920×1080 MJPEG stream of the camera* and not its H.264 stream! uv4l does not delete anyt...

Re: uv4l accept/decline calls on Raspberry

The project requires the user on the Raspberry end to be able to accept or decline a call and I was wondering if there is a way to do this. I have looked around in the uv4l config file and can't say I have found a setting related to this (which is not to say isn't there, I might have missed it). I'...

Re: WebRTC peer without a browser

IMHO all these UV4L projects are WebRTC streamer only, exposing a signalling server interface via HTML. This requires the PI to be publicly available on the Internet, which is mostly not possible. It would be good to nothing if this were true. UV4L supports STUN/TURN servers for NAT traversal when ...

I have done all the recommended settings except to buy a secured (HTTPS) licence.
there is no such thing as "HTTPS license to buy". Just enable HTTPS according to the doc, if you want/need it.

Were you able to get this to work? I set up the webrtc audio sharing but could only connect one client at a time. You need Janus as a gateway (it can be installed on the same Rpi).

Heard the exact statement from Novell, Microsoft, VMWare and Citrix over the years and in all cases ended up having to use ‘normal’ tools to do some jobs.

Hi guys, I am curious if you can play RetroPie games in a browser + keyboard with this:

because of the very little latency involved (e.g. <~200ms}
