1. there is only decoding in your pipeline. if there is only one rtsp source, decoding should not be the bottleneck. you can use "sudo tegrastats " to monitor the decoding/encoding utilization.
2. you can add timestamp on the video or make the camera towards the clock. please refer to this [faq](https://forums.developer.nvidia.com/t/deepstream-sdk-faq/80236/12) for how to “Enable Latency measurement for deepstream sample apps”.
3. please refer to [latency](https://gstreamer.freedesktop.org/documentation/rtsp/rtspsrc.html?gi-language=c#rtspsrc:latency) of rtspsrc.
4. please use nvv4l2decoder or nvjpegdec to decode jpg.
