imx8m-plus Basler daA4200-30mci camera not using Pylon software

[malik_cisse]

Hi,

Hi,
Is there a way to launch Basler daA4200-30mci camera module not using Pylon software.
 I was able to make the camera module work from within Basler's Pylon software UI interface.

However I would also like to use the camera using gst-launch-1.0 (gstreamer command line) directly since this would be the way the QT application will use the camera.
So far I am unable to see any video playing when using similar commands to:
gst-launch-1.0 v4l2src device=/dev/video1 ! waylandsink

also variants to this command will not give any error messages but no video is playing.
Any idea?
Thank you

did you use nxp imx8mp board and demo images? if yes, current bsp supports this with gstreamer as default, this is from my test

Hi Joanxie,

I am using DART-MX8M-PLUS Evaluation Kit from Variscite:

https://www.variscite.com/product/system-on-module-som/cortex-a53-krait/dart-mx8m-plus-nxp-i-mx-8m-p...

Are you sure you are Basler daA4200-30mc? From your debug log I can see that imx8mp embedded ISP is used however daA4200-30mci has its own independent inbuilt ISP and it does not use imx8mp-ISP. daA4200-30mci is rather based on ISI interface directly.

Therefore I am not sure if your example uses this particular camera module.
Please give me your thoughts on this,

BR, M.Cisse

Hi @malik_cisse,

Did you check https://github.com/basler/meta-basler-imx8 ? I think it should be helpful. It's a yocto layer for Basler dart BCON MIPI cameras for i.MX8 platform. 

I've seen they list in the example:

• daA2500-60mci connected on CSI1, no camera on CSI2: imx8mp-evk-basler-isi0.dtb

It's not the same camera as yours, but it still has in-built ISP. Unfortunately we don't have any other Basler camera to test except for daA3840-30mc. 

Let me know what you think.

Best regards,

Diana

Hi Diana

Thank you for your feedback which I often find very helpful.

The current statement from Basler is that basler-daa4200-30mci is only accessible via Basler Pylon software. Gstreamer support is provided via extra Pylon-plugin

https://www.baslerweb.com/en/company/news-press/news/pylon-gstreamer-plug-in-for-basler-cameras/8774...

I did not tested this yet but if it works fine, I don't mind using that.

How can I build the pluin with yocto?

[dianapredescu]

Dear @malik_cisse ,

Thanks for the information. Please let me know if you manage to build and try that pylonsrc plugin. I might be interested as well. I'll let you know if I'm going to try it on my side.

Best regards,

Diana

my module is DEV KIT DAA3840-30MC -IMXSAS, and which uses ISP, since you use the third party company board, I suggest that you can contact them to double confirm
