Basler Camera on Nano - Gstreamer Interface

I have begun working with a Basler MIPI camera on Nano, and I wanted to reach out to get a sense of what others are using for an interface to create gstreamer pipelines.

The camera doesn’t immediately show available resolutions and frame rates in response to:

v4l2-ctl --list-formats-ext

Instead, the device displays:

ioctl: VIDIOC_ENUM_FMT
	Index       : 0
	Type        : Video Capture
	Pixel Format: 'RGGB'
	Name        : 8-bit Bayer RGRG/GBGB

	Index       : 1
	Type        : Video Capture
	Pixel Format: 'RG10'
	Name        : 10-bit Bayer RGRG/GBGB

	Index       : 2
	Type        : Video Capture
	Pixel Format: 'RG12'
	Name        : 12-bit Bayer RGRG/GBGB

	Index       : 3
	Type        : Video Capture
	Pixel Format: 'AR24'
	Name        : 32-bit BGRA 8-8-8-8

	Index       : 4
	Type        : Video Capture
	Pixel Format: 'UYVY'
	Name        : UYVY 4:2:2

	Index       : 5
	Type        : Video Capture
	Pixel Format: 'NV16'
	Name        : Y/CbCr 4:2:2

	Index       : 6
	Type        : Video Capture
	Pixel Format: 'YUYV'
	Name        : YUYV 4:2:2

I have started using the Python library from Basler, and found this great repo which is working very well:

But I am wondering if I’m overlooking av4l2-ctl way to attach the camera to a standard gst pipeline for testing and creating network streams.

Thank you!

Try the v4l2src for the gst-launch-1.0
You should be able find some reference from forum topic.

Hi @ShaneCCC ,

Thanks for responding. I am familiar with gst-launch-1.0 and have used it frequently with cameras.

This specific situation is different for me in that the way that the Basler camera presents itself to v4l. I have provided the detail in my original question.

Would you be able to speak to using gst with an interface difference such as this? Or point me at a forum link that deals with it specifically?

Thank you!

Have a reference to below topic. You may need to modify the parameter like resolution and pixel format in the pipeline.

Just to close this out - This particular Basler camera requires a driver link and is not available as a typical v4l2 camera as shown by the suggestion above.

I appreciate your input, thanks again!
