DeepStream using nvurisrcbin leads to a decrease in frame rate

[junshengy]

This issue should not be related to nvurisrcbin, but should be caused by the configuration of nvstreammux.

g_object_set (G_OBJECT (uri_decode_bin), "file-loop", TRUE, NULL);

This parameter only use for file source, like file://. for rtsp source is useless.

@3260257634

g_object_set (G_OBJECT (uri_decode_bin), "select-rtp-protocol", 0, NULL);

Set select-rtp-protocol to 4 to enable rtp over tcp, if your camera supports it. This can avoid udp packet loss problems, but will increase some latency.

This problem is probably caused by the parameter configuration of nvstreammux. For rtsp, first set live-source to 1. In addition, please refer to this FAQ to adjust the parameters
