rtsp inference

I have been trying to make this pipeline work for a couple of days already and hit a wall…
I am trying to make a “server” that takes a rtsp stream and then re-streams it with gst/rtsp-server

The pipeline looks something like this:

rtspsrc location="rtsp://192.168.0.66"
   ! rtph264depay ! h264parse ! omxh264dec
   ! m.sink_0 nvstreammux name=m batch-size=1 live-source=true width=2688 height=1520
   ! nvinfer config-file-path=nvinfer.txt
   ! nvvidconv ! video/x-raw(memory:NVMM),format=RGBA ! nvdsosd ! nvvidconv ! video/x-raw(memory:NVMM),format=I420
   ! omxh264enc ! h264parse ! rtph264pay name=pay0 pt=96

I found that nvstreammux is required for nvinfer (Deepstream SDK 3.0)(please correct me if I am wrong). Now it looks like it complains about the number of surfaces. I have been looking through the examples and they do not setup anything else, what am I missing?
Removing lines 3 and 4 works and I am able to re-stream the video.
Here is the output:

Thanks in advance,

Hi,
DS3.0 is not for Nano. Please upgrade to DS4.0. Your usecase is similar to deepstream-test3. Please take a look at the sample.

3

My mistake, I am on DS4.0

I looked at that example and it is not streaming to rtsp. The GstRTSPServer and GstRTSPMediaFactory play nice when you have a pipeline that is string-based. deepstream-test3 is not string based, it builds and links all the pipeline’s elements manually.

I was looking for someone to be able to identify what could be missing in my string-based pipeline.

Hi,
You may refer to the samples to construct the string-based pipeline. In running DS4.0, please use nvv4l2decoder instead of omxh264dec, and nvv4l2h264enc/nvv4l2h265enc instead of omxh264enc/omxh265enc. We have unified v4l2 plugins for desktop GPUs and Jetson platforms.

I tried using nvv4l2decoder/nvv4l2h264enc with a simpler pipeline and didnt work, here is the pipeline I used:

rtspsrc location="rtsp://192.168.0.66"
        ! rtph264depay ! h264parse ! nvv4l2decoder
        ! nvv4l2h264enc ! h264parse ! rtph264pay name=pay0 pt=96

Hi,
You may try deepstream-app and enable rtspsink in the config file.
Please refer to document and the post

I want to take the input from a web camera to my Jetson NANO and run yolo object detector on it and stream the result to a Jetson Xavier as RSTP. Is there a sample app I should specifically look at ? If not, can you help me to set the necessary configurations.

8

Hi,
For running Yolo, please check

deepstream_sdk_v4.0_jetson\sources\objectDetector_Yolo\README
9

Thanks, through the deepstream-app it works… now to play on getting a better detection…
In the future I will try to recreate the pipeline with gstream that deepstream-app is using… It would be helpful to figure out what was missing in the above pipeline

Hi,
Since there are bunch of parameters being configured into a deepstream pipeline, we design the config file as a quick start guide. All samples are open source and please refer to it to construct the pipeline.
