hello guys!

anyone got the same issue?

./Raspi_VLC_Webcam_Stream.sh 0

Output:

unknown control 'led1_mode'

Error [2]: Folder passed in argument is invalid or does not exist. Aborting.

Your solution is so great for introducing vlc via the source code that you have, I've been using it as my reference for the last couple of years. Thank you for putting this on the internet!

I was curious if you also stream audio at all using this? I'm not having much success in getting audio off of the c920. I put all of my issues into this question on the raspberry pi stack exchange.

Do you have any guides/notes that aren't maybe public for getting the audio to work out?

Thanks this looks like a nice project for my Logitech C920 but I cannot get started.

pi@raspberrypi:~/RaspiVWS $ ./Raspi_VLC_Webcam_Stream.sh -V 0 8090
returns
Error [1]: Device /dev/video0 required but could not be found. Aborting.

however this command works OK
cvlc v4l2:///dev/video0:chroma=h264 :input-slave=alsa://hw:1,0 --sout '#transcode{acodec=mpga,ab=128,channels=2,samplerate=44100,threads=4,audio-sync=1}:standard{access=http,mux=ts,mime=video/ts,dst=:8090}'

Describe the bug
Known bug VLC 3.0.16 vlc on raspbian does not accept the ALSA url code.videolan.org/videolan/vlc/-/issues/26054 so :input-slave=alsa://hw:1,0 won't work with this VLC version

• Device: raspberry pi
• OS: raspbian 11 bullseye

Describe the bug
I have tried multiple cameras, and a specifically a Logitech C920. The program is unable to detect the cameras:
Error [1]: Device /dev/video0 required but could not be found. Aborting.

To Reproduce
Steps to reproduce the behavior:

1. Connect camera to device
2. Ensure the camera is recognized by the pi: v4l2-ctl --list-devices
3. Check output: HD Pro Webcam C920 (usb-0000:01:00.0-1.3): /dev/video0 /dev/video1
4. Run script ./Raspi_VLC_Webcam_Stream.sh 0

Expected behavior
The program should run.

Screenshots

Thank you for this project, it helped me get my h.264 usb camera (not c920) working well with a raspi running my front gate doorbell.
Audio-sync does not seem to be a valid command-line parameter, at least according to available vlc documentation. When output is verbose you get a warning to the same meaning as well "main stream out warning: option audio-sync is unknown".
There is however an " --audio-desync" option that takes a milliseconds argument to attempt to compensate for video and audio being out of sync.
This could be a new feature to add.
