Odd behaviour of RTSP output streams

[z3n667]

When running deepstream with a RTSP input of 30fps and a RTSP output of around 20fps (best model can do) the stream is very choppy and has a lot of frame drops.

If I do the same setup, but with an additional EGL (HDMI) output the RTSP output stream is much more stable, it still eventually drop frames, but it’s much smoother.

I played with QoS and Sync settings, nothing seem to fix the issue with RTSP alone, is there any advice?

Thanks!

Hi,
Several topics for your reference:

rtsp output working but a lot of frame errors ?

Hi, I frames have larger size. It is more like an issue in bandwidth or buffering. You may try to modify deepstream-app to configure some properties in rtspsrc or queue plugin.

deepstream4.0 with rtsp of sink makes the picture distortion with high bitrate

Hi, Please check https://devtalk.nvidia.com/default/topic/1065973/deepstream-sdk/-is-deepstream4-0-with-rtsp-hardcode-for-h264-/post/5398271/#5398271 There is hardware engine for video encoding. Since ‘EglSink + File Save’ works fine, it should not be an issue in encoding performance. Just found It worth a try of tuning MTU size. Please configure it to different values and try again.

You may also try local streaming on Xavier:

$ sudo jetson_clocks
$ gst-launch-1.0 uridecodebin uri=rtsp://127.0.0.1:8554/ds-test ! nvoverlaysink sync=false
