Hello,
I would like to use Deepstream only for OSD functionality. I would like to use it using python bindings and I’ve already managed it but I’ve an issue relative to nvstreammux.
In fact this gst plugin, that for what I’ve understood is requied in order to add frame meta data, causes a kind of lag if video input is live.
If I use a simple pipeline like:
Please provide complete information as applicable to your setup.
• Hardware Platform (Jetson / GPU) • DeepStream Version • JetPack Version (valid for Jetson only) • TensorRT Version • NVIDIA GPU Driver Version (valid for GPU only) • Issue Type( questions, new requirements, bugs) • How to reproduce the issue ?

Including the module name-for which plugin or for which sample application, the function description)
• Hardware Platform (Jetson / GPU): Jetson Nano • DeepStream Version: 5.1 (manually updated, issue was available also in 5.0) • JetPack Version (valid for Jetson only): 4.4 • TensorRT Version: 7.1.3 • NVIDIA GPU Driver Version (valid for GPU only): No • Issue Type( questions, new requirements, bugs): Issue • How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing): Starting from deepstream_test1_rtsp_out.py, I’ve generated a Gstreamer pipeline that reads from an RTSP source and pushes video in another RTSP server. As you can see from my pipelines and from video samples if I use nvstreammux, video output is lagging. Maybe I’m doing something wrong but I cannot understand what. • Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description): no
Seems there is no performance issue with the first pipeline. Can you try to set “sync=0” with rtspclientsink plugin?
And can you upgrade to latest deepstream 6.0 SDK and try with the first pipeline? You can also try to set “sync-input=true” with nvstreammux with DS 6.0 SDK.
