Deepstream-app, deepstream_test3, test5, with multi-RTSP streams

  1. I can run deepstream-app -c deepstream_app_config.txt , with 8 rtsps , the issue is the OSD plugin on the srceen display, balck, green, or frozen. the FPS printf on the terminal : 0.00, 0.00, 24.30, 25.01, 0.00,0.00,0.00,0.00;

  2. I use command line : gst-launch-1.0 uridecodebin uri=rtsp:admin:admin123@ !nveglglessink, test every rtsp, I can get the screen display normal.

  3. with ./deepstream-test3, test5 with multi-rtsp streams, (the total rtsp num is 8), like uri=rtsp://admin:admin123@;uri=rtsp://admin:dixin_Admin123@;uri=rtsp://admin:dixin_Admin123@;uri=rtsp://admin:dixin_Admin123@, etc. I Can get the num_freams_in_batch in NvDsbachMeta , batch_meta->num_frams_in_batch, batch_meta ->max_frames_in_batch in appsink . when the pipline runing, the issue is , num_freams_in_batch always less than max_freams_in_batch, like 3, 4, 6, < 8; the OSD plugin, display on the srceen, balck, green, or frozen.

  4. without OSD-dispaly sink, num_freams_in_batch still less than max_freams_in_batch.

Please provide complete information as applicable to your setup.

Can you share the output of “nvidis-smi” when running 8 steams?

  1. GPU 0 , which deepstream-app used.
  2. GPU-Util 35%~50%.

Seems there is heavy packet lost with your rtsp sources, please check your rtsp servers and network status( For 8 rtsp streams at the same time). And please make sure the “live-source=1” is set in your streammux settings in deepstream-app configuration file.

I really appreciate your help.

  1. I check my rtsp servers and network status , my switch is 100 Gigabit switch. 8 rtsp streams at the same time.
  2. still black, green, frozen on the display .
  3. pipeline block ? or RTX2080Ti can’t hold multi-rtsp streams more than 3, or 4 ?

  1. This .png file, my pipeline detail .
    rtsp==> urideccodebin =>
    rtsp==> urideccodebin =>
    rtsp==> urideccodebin => streammux => nvinfer =>tee => appsink
    -------------------------------------------------------.--------------- =>render
    rtsp==> urideccodebin =>
    rtsp==> urideccodebin =>

  2. streammux, live_source = 1 ;

You can monitor the CPU and GPU usage during your app running to find out the bottleneck.

This is caused by packet lost during network transferring.

appreciated for your suggestion,

It seems like, ! WOW, I GOT IT !, Just replace the Network Switch , 1000M!

Glad to know the issue is resolved.
