VLC picture is too late to be displayed

In Deepstream pipeline: I use yolov3 model (batchsize 16) in nvinfer,and sink is rtmpsink;
the stream server is nginx with http-flv model.
when camera is 1 the stream is good
when camera is 8 the stream is warn by VLC:picture is too late to be displayed … ;and Viewing the stream through the browser is stuck。Is it processed at the push end to make the video stream smoother or at the playback end?

did you boost Jetson device clock?

$ sudo nvpmodel -m --for MAX perf and power mode is 0
$ sudo jetson_clocks

do you run with deepstream-app , or deepstream application?
if deepstream-app, you can use “export NVDS_ENABLE_COMPONENT_LATENCY_MEASUREMENT=1” to check the plugin latency.
if deepstream application, refer to Slow real-time performance when running custom YOLOv3 app - #7 by mchi to measure the output fps
