Unable to load deep stream with MJPEG pixel format

Hi,

I am using Jetson nano with deepstream version 5.1. I wanted to test CustomVision AI with deepstream using USB camera with format MJPEG. However, I am getting the following error :

My camera configuration is as follows:

ist-formats
SPCA2650 AV Camera (usb-70090000.xusb-2.2):
/dev/video0

ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture

Name : Motion-JPEG

Index       : 1
Type        : Video Capture
Pixel Format: 'YUYV'
Name        : YUYV 4:2:2

Hi,
By default it is not supported in deepstream-app and you would need to do customization. Please check if you can launch it in gst-launch-1.0 command like:

$ gst-launch-1.0 v4l2src ! jpegparse ! nvv4l2decoder mjpeg=1 ! nvoverlaysink

Hi,
You need to configure width, height, framerate per the source like:

v4l2src ! image/jpeg,width=_WIDTH_,height=_HEIGHT_,framerate=_FRATE_ ! ...

Hi,

Here’s a code I tried with output:
gst-launch-1.0 v4l2src ! video/x-raw,format=MJPG,width=640,height=480,framerate=25/1 ! jpegparse ! nvv4l2decoder mjpeg=1 ! nvoverlaysink
WARNING: erroneous pipeline: could not link v4l2src0 to jpegparse0, neither element can handle caps video/x-raw, format=(string)MJPG, width=(int)640, height=(int)480, framerate=(fraction)25/1

Kindly excuse me if the code has error. I am quite new to shell scripting.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi,
Please share information of the source:

$ v4l2-ctl -d /dev/videoX --list-formats-ext
