Icamerasrc not working with device-id instead of device-name

[brmarkus]

Can you provide more details about your environment (system, operating system, camera, connection), please?
Which versions do you use?
Can you provide logs?
Do you see a regression?

[rioryugen]

I am using yocto linux as OS, Camera-1 :ov13b10 , camera-2:ov14b10. Not worked in older versions too. Below is the command i use.

gst-launch-1.0 icamerasrc device=/dev/video0 af-mode=2 printfps=true ! video/x-raw,width=1280,height=720,format=NV12,framerate=60/1 ! autovideosink . Let me know if u have any parallel camera command.

[brmarkus]

Do you get any logs, from gstreamer, from icamerasrc, from IPU - user-space logs and kernel-space logs?

For the engineering team to analyze they will ask you for logs and more details about your environment (which HW, which kernel, which version of icamerasrc, which version of IPU, camera-config)

i have the following scenario, i have 2 cams connected to the system. both OV13B10. Can u share me the command to run these commands parallely. Will run the command and get us the relevant logs based on it. Want to validate from command side first

Do you see a pileline with one camera working?
From the examples under https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api?tab=readme-ov-file#pipeline-examples:

(depends on how the sensor is configured and actually named in the config file under https://github.com/intel/ipu6-camera-hal )

sudo -E gst-launch-1.0 icamerasrc device-name=ov13b10-wf af-mode=2 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! ximagesink

[rioryugen]

yeah 1 camera is working with folllowing command: cameraDebug=4095 gst-launch-1.0 icamerasrc device-name=ov13b10-wf af-mode=2 printfps=true ! video/x-raw,width=1280,height=720,format=NV12,framerate=60/1 ! autovideosink , but im not able to see the second camera or i am not seeing the support for the parameter "device=/dev/video0"

[brmarkus]

What do you mean with "not able to see the second camera"?
Do you see a gstreamer command line working for the second camera like you see working for the first camera?
Have you tried connecting one camera only? Connecting to the same port the other camera was working?
Do you use virtual channels?

Some long time ago we used icamerasrc in IoTG-automotive with the GordonPeak project for several customers successfully (usually using virtual channels due to the high amount of concurrently used cameras for e.g. 360° surround-view), created very detailed Wiki pages. But don't have access to the old projects from outside anylonger.

Exp1: Connected 1st camera in first port and ran the command-Working
Exp2: Connected 2nd camera in second port and ran the command-Working.
Exp3: Connected 1& 2nd cameras in respective ports. TBH i dont know the "icamerasrc" command to run the parallel stream. Was able to run only 1 stream.

Virtual Channels im not sure. Can you provide me more details on it.

[brmarkus]

Virtual channels - when you need to use many more cameras (but requires a companion chip in your HW design).

That sounds great, both cameras are working separately.

Experiment with e.g. videotestsrc and with different ways to render multiple camera streams side-by-side in one window or in multiple windows:

gst-launch-1.0 videotestsrc ! video/x-raw,width=160,height=120 ! m.sink_0 \ videotestsrc ! video/x-raw,width=160,height=120 ! m.sink_1 \ videomixer name=m sink_1::xpos=160 ! video/x-raw,width=320,height=120 ! xvimagesink

As with videotestsrc, just use icamerasrc multiple times - you might want to use multiple queue.

[rioryugen]

getting following error.

[brmarkus]

Ahh, ok, hold on.
My copy&paste broke the escaping into a new line using a single backslash.
The command line spans multiple lines:

gst-launch-1.0 videotestsrc ! video/x-raw,width=160,height=120 ! m.sink_0 \
videotestsrc ! video/x-raw,width=160,height=120 ! m.sink_1 \
videomixer name=m sink_1::xpos=160 ! video/x-raw,width=320,height=120 ! xvimagesink

(attention: no space, no characters after the backslash!)

Without breaking into multiple lines, without backslashes:

gst-launch-1.0 videotestsrc ! video/x-raw,width=160,height=120 ! m.sink_0 videotestsrc ! video/x-raw,width=160,height=120 ! m.sink_1 videomixer name=m sink_1::xpos=160 ! video/x-raw,width=320,height=120 ! xvimagesink

You could also use multiple xvimagesink and every camera stream would get its own windows - instead of compositing them into one window with videomixer (videomixer is using precious CPU resources to composite the camera stream into one!)

[rioryugen]

how do i specify camera "gst-launch-1.0 videotestsrc ! video/x-raw,width=160,height=120 ! m.sink_0 videotestsrc ! video/x-raw,width=160,height=120 ! m.sink_1 videomixer name=m sink_1::xpos=160 ! video/x-raw,width=320,height=120 ! xvimagesink"
?

[brmarkus]

This example was shows to experiment how the multiple camera streams could look like when compositing them into one frame - instead of the plugin videomixer (is using the CPU for compositing!!) you could use other plugins or composite programatically.

The plugin videotestsrc is just a video test source to simulate a camera stream - you can see even two of them to simulate two camera streams.
Use icamerasrc device-name=ov13b10-wf af-mode=2 as before (you might alos adapt video/x-raw,width=1280,height=720,format=NV12,framerate=60/1.

Or adapt the pipeline to use two xvimagesink - then you will get two separate windows.
