How to force Nvidia Jetson Nano USB Camera Resolution to 1080P

Accelerated Computing Intelligent Video Analytics DeepStream SDK

Pixel format changing to YUYV 640x480 every time I run Deepstream App with USB camera as a source.

I’d like to run source @1080P. How can I force deepstream app to use MJPEG or H.264 @1920x1080? Is there a way to change these settings in the deepstream app /config files?

Hi,
Please try

$ gst-launch-1.0 v4l2src device=/dev/video0 ! image/jpeg,width=1920,height=1080,framerate=30/1 ! jpegparse ! nvv4l2decoder mjpeg=1 ! nvoverlaysink sync=false

Hi DaneLLL,

Thanks for replying back. I’ve tried your suggestion and that worked just fine. How can I force deepstream-app to use MJPG? Is there any specific parameter that I should use?

Thanks.

Hi ,
MJPEG decoding is not supported in deepstream-app. You would need to refer to deepstream-image-decode-test. Please check

deepstream-5.0/sources/apps/sample_apps/deepstream-image-decode-test/README

Ok. Thanks.
