Deepstream 6.1 python rtsp in rtsp out demo is not working

rahul19 · July 24, 2022, 9:15pm

My set up is: T4 GPU, Deepstream 6.1, Tensorrt 8.2.5.1, Cuda 11.6, cuDnn 8.4, Driver 510.47.03

I have successfully installed Deepstream 6.1 and can run commands like deepstream-app --version-all. I cloned the Deepstream python apps repository from deepstream_python_apps/apps/deepstream-rtsp-in-rtsp-out at master · NVIDIA-AI-IOT/deepstream_python_apps · GitHub, and I installed the Deepstream 6.1 python bindings with the .whl file. I tried to run the sample rtsp in rtsp out program, but I keep getting an error where the pipeline freezes indefinitely near hitting the nvv412decoder0.

The command I am using to run the python sample app is python3 deepstream_test1_rtsp_in_rtsp_out.py -i rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4 -g nvinfer

The rtsp link is a public rtsp from RTSP Stream Test | Wowza

The only changes I made were to the dstest1_pgie_config.txt file where I changed all the …/…/…/…/ paths to /opt/nvidia/deepstream/deepstream/.

Theoretically, because this is a sample app, it should work, so I’m thinking that the problem should be in the way I set up deepstream. However, I think I have the right version of all the dependencies installed, so I don’t know where to proceed from here.

Here is the output with GST_DEBUG=2:

Whenever I run the deep stream python sample rtsp in rtsp out app from the repo deepstream_python_apps/apps/deepstream-rtsp-in-rtsp-out at master · NVIDIA-AI-IOT/deepstream_python_apps · GitHub, I get an error in the pipeline where it freezes near the nvv4l2decoder0 element

There is a message “Error binding to address 0.0.0.0:8554: Address already in use”, it seems there is another progress running and occupying the port, can you change the port, or double-check and kill the existing testing program, or simply reboot the device and retest?

I rebooted the device, tested the program right after, and it still had the same issue of pausing.

Please check by netstat -tulpn | grep 8554 who occupy the port.
Second, run by increasing debug level to 5 to capture rtsprc debug log. GST_DEBUG=rtspsrc:5

rahul19 · July 26, 2022, 7:27am

For some reason, setting GST_DEBUG=rtspsrc:5 did not change the output. Before testing the sample app, the “netstat -tulpn | grep 8554” did not show any output. Here is the console log. The reason there is a control Z in the bottom of the log is because the pipeline ran indefinetely again.

sudo netstat -tulpn | grep 8554

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

Sorry. for gstreamer python debug, you can refer to Gstreamer 1.0 Python Debug · GitHub
Your app running success. you can view the output via vlc through rtsp://ip:8554/ds-test
