On RaspPi3, switched from on board video cam to USB with VLC, how change command line code?

Hello all, I've had no luck in the pi or arducam (camera manufacturer) forum with any responses so figured I'd go right to the source.

I have a raspi that had the ribbon cable camera that I use as a security cam. Right now it works fine with a script that starts up automatically that uses VLC to put the stream to port 8083 via http so with port forwarding, I can access it very easily anywhere I can install VLC again. Anywho, the low light performance is terrible, so I saw the same company offered a lolight version but its USB. I can't figure out how to get VLC to stream that to 8083 now. The original code used raspivid which does not support USB access.


raspivid -o - -t 0 -w 1280 -h 720 -fps 30 | cvlc -vvv stream:///dev/stdin --sout ‘#standard{access=http,mux=ts,dst=:8083}’ :demux=h264


the codes I've tried to replace it with so far finding via interweb searches seem to be close but no cigar.


cvlc v4l2:///dev/video0:chroma=h264 --sout :standard{access=http,mux=ts,mime=video/ts,dst=:8083}

(this starts to run but it reports 1 line back and doesnt proceed past it:
VLC media player 3.0.17.4 Vetinari (revision 3.0.13-8-g41878ff4f2)


cvlc v4l2:// :v4l2-dev=/dev/video0 | cvlc -vvv stream:///dev/stdin --sout ‘#standard{access=http,mux=ts,dst=:8083}’ :demux=h264

(this starts a VLC instance and shows the camera video, but there is nothing being broadcast to 8083, plus i imagine having the video being shown in a VLC instance on the pi the entire time would kill the already iffy frame rate with a second remote viewing)


cvlc v4l2:///dev/video0:chroma=h264 | cvlc -vvv stream:///dev/v/stdin --sout '#standard{access=http,mux=ts,mime=video/ts,dst=:8083}' :demux=h264

(this starts a vlc instance like above too but no stream but shows below:)
VLC media player 3.0.17.4 Vetinari (revision 3.0.13-8-g41878ff4f2)
VLC media player 3.0.17.4 Vetinari (revision 3.0.13-8-g41878ff4f2)
libEGL warning: DRI2: failed to authenticate



any help would be greatly appreciated, i'm not savvy on command lines beyond copying what i see any making adjustments to the obvious.

thank you!

ps. if it matters,its arducam 1080p low light wdr cmos imx291, from the box: number x002hzmsph ub020201
and shows up as "Bus 001 Device 004: ID 0c45:6366 Microdia" on lsusb. the camera is definitely working, and using the VLC gui app I can see video by selecting the capture device or the 1 code above that. i also tried using the gui vlc stream guide but that wasnt working either and it doesnt let you select a port. i tried putting in the dst=:8083 in the code it generates for you and without, but still didnt work. it would show the video in vlc, but no stream starts that i could find even at 8080 which i read was the default.

You may wish to try libcamera since they are deprecating the raspicam utilities.

This is what I've been using to stream rtsp:

libcamera-vid -t 0 --inline -o - | cvlc stream:///dev/stdin --sout '#rtp{dst=192.168.1.18,port=8554,sdp=rtsp://192.168.1.18:8080/cam.sdp}' :demux=h264

be sure to use raspberry pi's version of libcamera: git clone https://github.com/raspberrypi/libcamera.git
and the libcamera apps: git clone https://github.com/raspberrypi/libcamera-apps.git

caveat 1: you will need to build these. the docs on pi site are good. beware, that if you have an existing version of libcamera or libcamera-dev on the pi. you may have problems when building the libcamera apps as cmake will find the other version first. look in /usr/lib for a libcamera file or in /usr/include. try uninstalling or reflash pi from scratch was my solution, then build libcamera before installing/building any other stuff that uses the cam (cmake finds the right version in this scenario)

caveat 2: i'm running ubuntu 22.10 on a pi4, not the Pi OS (which may not really be a problem)
