Difficulties displaying RTSP output from DeepStream

[gabrielmstefanello058]

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) Jetson Orin Nano Dev kit
• DeepStream Version 6.4
• JetPack Version (valid for Jetson only) 6.0
• TensorRT Version 8.6.2
• Cuda Version 12.2

• Issue Type( questions, new requirements, bugs)

    I'm trying to display the ouput from DeepStream app with RTSP but i am facing the error of getting a green screen as the stream output.

• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)

   Run deepstream-app with the following config file and try to visualize the RTSP output, I tried to get the display with:
        ffplay rtsp://10.117.0.42:8555/ds-test
        and also by VLC setting 'Network Stream' to the aproprieted path ( rtsp://localhost:8555/ds-test )

Deepstream_app_config.txt (2.9 KB)

or sometimes I get the following error with ffplay:

[h264 @ 0xffff64005860] decode_slice_header error
[h264 @ 0xffff64005860] no frame!
[h264 @ 0xffff64005860] non-existing PPS 0 referenced    0B f=0/0

and:

With VLC

Update:

I had modified NVDS_ELEM_VIDEO_CONV “nvvideoconvert” to
NVDS_ELEM_VIDEO_CONV “nvvidconv” and now I can get some frames. But the stream appears to be froze for some seconds and then update some frames and after that freeze again… Does anyone know what may be causing this problem?

The blue screen issue is a known bug for DS 6.4. Could you update that to the latest version DS7.0?

[gabrielmstefanello058]

Hi, I don’t think its necessary to update the Deepstream to 7.0, since I had solved the green freezed screen, my actual problem is that the RTSP stream is pretty slow, running about 1FPS and sometimes freezing the screen for some seconds. What might be interesting is that if I convert the stream to a mp4 video I can get the video with great FPS ( 8 fps in my case, the performance that was being displayed while i was displaying the output in my screen)…
I would like to display the stream with the same performance, but I don’t know what may be causing this problem.

This is related to your machine performance and network environment. You can try to boost-the-clocks to improve the performance first.

[gabrielmstefanello058]

Thanks for the reply, I don’t actually think that the problem is due to my machine and network performance. I tried running DeepStream-app with GST_DEBUG=3 and I got a interesting sequence of warnings that might indicate some problem, im about to upload the log in a file
log.txt (9.5 KB)

Besides this log I changed the input type to an URI video and I noticed that the stream aparently runs for some seconds and freeze for another sequence of seconds, looking like as it is loading the frames to be displayed.

And the reason for not thinking that the network performance may be the problem is because I have at the moment after a speed test:

Latency: 11 ms

Download:138,38 Mb/s

Upload: 108,09 Mb/s

Update:
I have being searching for some solutions and I found that I do have the file corresponding to the nvv4l2h264enc, but the gst dont recognize it, because when I run ´´´gst-inspect-1.0 nvv4l2h264enc´´´ I get:
´´´No such element or plugin 'nvv4l2h264enc´´´

Path for the plugin: /usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstnvvideo4linux2.so

Jetson Orin Nano cannot support hardware encoder. From your description, it could be that the software encoder is affecting the performance.

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
