MINISASTOCSI with 8MMINILPD4 LF_v6.1.22 vs. LF_6.12.34 Linux

I have the MINISASTOCSI camera module working with the older factory build for the 8MMINILPD4-EVK:
LF_v6.1.22-2.0.0_images_IMX8MMEVK

Using the following command successfully streams video from the camera through to the HDMI monitor on the mini-SAS-to-HDMI output:

gst-launch-1.0 v4l2src ! video/x-raw,width=1920,height=1080 ! autovideosink

I flashed the later version of FW, in this example the latest:
LF_v6.12.34-2.1.0_images_IMX8MMEVK

G-Streamer does not work:
root@imx8mmevk:~# gst-launch-1.0 v4l2src ! video/x-raw,width=1920,height=1080 ! autovideosink
Setting pipeline to PAUSED ...
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Device '/dev/video0' is not a capture device.
Additional debug info:

Capabilities: 0x4204000
ERROR: pipeline doesn't want to preroll.
Failed to set pipeline to PAUSED.
Setting pipeline to NULL ...

root@imx8mmevk:~#

...So I used found the device with v4l2:

root@imx8mmevk:~# v4l2-ctl --list-devices
imx-capture (platform:32e20000.csi):
/dev/video2
/dev/media0

/dev/video1

vsi_v4l2enc (platform:vsi_v4l2enc):
/dev/video0

root@imx8mmevk:~#

...so then tried again with the device:

root@imx8mmevk:~# gst-launch-1.0 v4l2src device=/dev/video2 ! video/x-raw,width=1920,height=1080 ! autovideosink
Setting pipeline to PAUSED ...

So now my question is what changed in the BSP after LF_v6.1.22... which now cannot get the buffer memory allocated?

Is the issue within v4l2 or in G-streamer or is it in the driver for MINISASTOCSI?

It would be really really nice to have updated documentation for MINISASTOCSI as well.

This is the list of supported (supposedly) formats:

And trying the suggested command still fails with the same error message:

Still seems to me that a bug was introduced into the build somewhere between 6.1.22 and 6.12.xx and given that g-streamer probably has not changed at all I would think the issue is with the NXP driver for the camera module or perhaps for the i.MX8MM hardware...

Re: MINISASTOCSI with 8MMINILPD4 LF_v6.1.22 vs. LF_6.12.34 Linux

Helo @Jordanyte

I hope you are doing very well.

Could you please set the below command:

v4l2-ctl --device=/dev/video2 --list-formats-ext

This will show the supported formats by camera.

Also, try the below:

gst-launch-1.0 v4l2src device=/dev/video2 ! video/x-raw,format=UYVY,width=1920,height=1080 ! autovideosink

(Thinking the UYVY is the supported format).

Best regards,

Salas.

Re: MINISASTOCSI with 8MMINILPD4 LF_v6.1.22 vs. LF_6.12.34 Linux

Hello @Jordanyte and @Manuel_Salas ,

I am running into the same issue with my IMX8MM and MINISASTOCSI. Getting the same errors in 6.12.34.

Were you able to find a solution to this problem? If so, do you mind sharing?

Thanks in advance,

Kasey
