I need to run 36 streams in deepstream python

Seems the decoder reaches its limit, please refer to table Jetson Modules, Support, Ecosystem, and Lineup | NVIDIA Developer.
You may use gst-launch-1.0 to check how many streams your nano can handle.

[gowtham2]

but in Jetson AGX Orin 64GB also same problem occurs

[fanzh]

could you share the whole logs? can you run four streams in deepstream?

[gowtham2]

able to run 12 stream in both jetson nano and Jetson AGX Orin 64GB. but can’t able to run more than 12 stream(ip cameras)

[fanzh]

does it crash at the beginning or after a while? can you share the whole logs? please do “export GST_DEBUG=4”, then run again you can redirect the logs to a file.

[gowtham2]

it doesn’t crash, simply exit

As checked via message, the Orin module you are using is 32GB module. The number of video decoder as:

Nano:
1x 4K60 | 2x 4K30 | 4x 1080p60 | 8x 1080p30 | 9x 720p60 (H.265 & H.264)

Orin:
1x 8K30 | 2x 4K60 | 4x 4K30 | 9x 1080p60| 18x 1080p30 (H.265)
1x 4K60 | 2x 4K30 | 5x 1080p60 | 11x 1080p30 (H.264)

Can you run multiple pipelines (“gst-lauch-1.0 uridecodebin uri=xx …”) to check whether the issue is caused by limit of decoder?

same error occurs, how to resolve this?

[fanzh]

gstrtspsrc.c(6563): gst_rtspsrc_send (): /GstPipeline:pipeline0/GstURIDecodeBin:uridecodebin0/GstRTSPSrc:source:
Service Unavailable (503)
ERROR: pipeline doesn’t want to preroll.

1. As the log shown, the rtsp source can’t support 12 connecting.
2. what is your rtsp source info? can you try gst-launch-1.0 uridecodebin uri=file:///opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.mp4 uridecodebin uri=file:///opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.mp4 … ?
   it should not be decoding issue if gst-launch-1.0 can decode 12 h264 files.

[gowtham2]

what is your rtsp source info?
I am using Dahua DVR for connecting ip cams, get rtsp urls

2. I try it runs, gst-launch-1.0 can decode more than 12 h264 files, I tried up to 24 h264 files, it run without any error

[fanzh]

1. what is your rtsp source info? like resolution, fps.
2. can your rtsp source support 12 rtsp connecting? from “Service Unavailable”, rtsp connecting failed.

[gowtham2]

1. resolution - 960×1080, fps -25

2. it support 12 rtsp stream, more than 12 I got following error “Service Unavailable”

[fanzh]

it should be a limitation of the camera. you can use different RTSP source, or use gstreamer plugin tee to duplicate one stream to many streams.

[gowtham2]

ok
thank you sir,
I got it

[fanzh]

Is this still an issue to support? Thanks

[gowtham2]

No issues
