Using overlay 2 in L4T 28.1 with TX2

Hi,

I’m using the following Gstreamer pipeline in L4T28.1-TX2 to render the preview in overlay 1:

gst-launch-1.0 v4l2src device=/dev/video0 ! “video/x-raw, format=(string)UYVY, width=(int)1280, height=(int)720” ! nvvidconv ! “video/x-raw(memory:NVMM), format=(string)I420, width=(int)1280, height=(int)720” ! nvoverlaysink overlay-w=640 overlay-h=480 overlay=1 sync=false

But with overlay=2, I encounter the following error:

nvidia@tegra-ubuntu:~$ gst-launch-1.0 v4l2src device=/dev/video0 ! “video/x-raw, format=(string)UYVY, width=(int)1280, height=(int)720” ! nvvidconv ! “video/x-raw(memory:NVMM), format=(string)I420, width=(int)1280, height=(int)720” ! nvoverlaysink overlay-w=640 overlay-h=480 overlay=2 sync=false

The same pipeline is working with both overlays in L4T 27.1. Is there any fix for this problem?

Best Regards!!

Hi ramprasadrp2412,

Thanks for reporting this issue, we’re investigating to find the cause, the status will be updated once clarified.

Cheers.

Hi ramprasadrp2412,

Could you please share me how to run gst-launch-1.0 pipeline for YUV sensor on L4T 28.1 with TX2?

On TX1 I could run everything as well.

On TX2 I could capture image as well with v4l2 utils. But when I tried to run gst-launch-1.0 pipeline as below:

gst-launch-1.0 v4l2src device=/dev/video0 ! 'video/x-raw,width=1280,height=720,format=(string)UYVY' ! nvvidconv ! 'video/x-raw(memory:NVMM),format=(string)NV12' ! nvoverlaysink

then got error

gst-launch-1.0 v4l2src device=/dev/video0 ! 'video/x-raw,width=1280,height=720,format=(string)UYVY' ! nvvidconv ! 'video/x-raw(memory:NVMM),format=(string)NV12' ! nvoverlaysink

@forever3000 From your v4l2-compliance out:

test VIDIOC_G_FMT: FAIL

Seems you haven’t configured for UYVY format. Check your dtsi file and sensor_common.c file for UYVY support.

Any update??

Please apply patches attached and try again.

Hi DaneLLL,

Its working. Now, I’m able to access overlay 2 after applying these patches.
Thanks a lot.

Hi ramprasadrp2412,

Could you please share me what changed for YUV sensor on L4T 28.1 with TX2?

On TX2 I could capture image as well with v4l2 utils and yavta.
But when I tried to run gstreamer pipeline with v4l2src, I encounter the following error:
