Seems the decoder reaches its limit, please refer to table [Jetson Modules, Support, Ecosystem, and Lineup | NVIDIA Developer](https://developer.nvidia.com/embedded/jetson-modules). You may use gst-launch-1.0 to check how many streams your nano can handle. ---

As checked via message, the Orin module you are using is 32GB module. The number of video decoder as: ```auto Nano: 1x 4K60 | 2x 4K30 | 4x 1080p60 | 8x 1080p30 | 9x 720p60 (H.265 & H.264) Orin: 1x 8K30 | 2x 4K60 | 4x 4K30 | 9x 1080p60| 18x 1080p30 (H.265) 1x 4K60 | 2x 4K30 | 5x 1080p60 | 11x 1080p30 (H.264) ``` Can you run multiple pipelines (“gst-lauch-1.0 uridecodebin uri=xx …”) to check whether the issue is caused by limit of decoder? ---

it should be a limitation of the camera. you can use different RTSP source, or use gstreamer plugin tee to duplicate one stream to many streams. ---
