USB MJPG Camera Not working: streaming stopped, reason not-negotiated (-4)

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

  1. please refer to this topic, especially in 28.3.1 part. from your logs, the camera can only output MJPG format data. first you can use gst-launch to debug how to use MJPEG data in DeepStream pipeline.

  2. please find video-format in the doc . currently deepstream-app can support raw data from camera, but can’t accept MJPEG format directly, which is an encoded data. deepstream-app is opensource, and you can customize to implement. the key code is create_camera_source_bin of opt\nvidia\deepstream\deepstream-6.2\sources\apps\apps-common\src\deepstream_source_bin.c. you need to add a nvv4l2decoder plugin.
