capture://v4l2/video0
Using the device you linked, I can get video but no audio using Ubuntu 24.04.2. Video looks great!
I tried the last one you posted as well, but that just spins.
capture://v4l2/video0/hw:Video,0/?framerate=60
Hi, have you had any luck on getting the audio working? The picture is coming through perfect now.
Not with //capture. I get the same results as @timstephens24 above. I did find an hdmi audio stripper in my parts bin and I am having better results combining the separate audio with the video and streaming it to channels via m3u. It seems like Linux doesn’t like capturing the audio and video from the usb, it will capture one or the other but not both at the same time. I might share some scripts if I can get something working. I’m working on starting and stopping the m3u transcode based on when the channel is tuned in and out.
Sounds good thanks. Do you think I'd have better luck with a windows 11 pc? It's a shame that Linux doesn't like doing both. I get both in VLC. Fingers crossed you get something stable with the audio stripper
Yes I think windows is working much better based on the above posts. I haven’t tried in windows myself though.
Does this help?
The Dell OptiPlex Micros are an excellent Channels bang for your buck. They have transcoding and I5 power with very low power usage.
You can get a 5060 under $100 on eBay and it will legitimately run Windows 11, a bunch of Dockers, and record 10 things at a time.
I just migrated to a 5090 ($160) for the extra cores and now I can record 20 things at once, run 8 Dockers, and use multiple threads to process commercials.
Through experimentation, I found that the I5 processors were power efficient but needed an I7 to run Chrome Capture for Channels. I went back to the I5 and ADBtuner so I wouldn't hear the fan running all day.
I can't tell you that a 7-year-old I5 processor will run the USB HDMI Capture hack, but it's gotta be better than the Pi.

Try adding /System/Library/CoreServices/launchservicesd under camera/audio/screen-recording permissions maybe?

Hi, this is what I'm getting now. Do I need to edit my config in channels? I am still getting video with the config that doesn't mention the audio or frame rate
Thanks
No diff, sorry.

Rpi is not suitable for this feature

Thanks, I'll invest in a windows 11 pc. Are all N95 devices suitable? Belink aren't commonly available in the UK.
Thanks

Any modern Intel machine is fine

I have an old i5 nuc running raspberry pi os. Would that be ok? I can't get windows 11 on it.
