rtsp source is not working

[barslan16]

Could you give a command line example of how to change video source to rtsp?
Although I tried many times, I could not run this command.

Thank you very much in advance, looking forward to your
I also add the error I got below.

Maybe you can try to test your rtsp-url on a gst-launch-1.0 first?

gst-launch-1.0 rtspsrc location=

[barslan16]

Thank you very much for your advice. I tried what you said.
When I run the code below, streaming is happening.
gst-launch-1.0 rtspsrc location='rtsp://admin:1234@192.168.1.143/H264?ch=1&subtype=0' ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! xvimagesink

However, when I run the code below, I get an error. I'm writing the error and code below.

python3 detect.py --tracker sort --videosrc rtsp://admin:1234@192.168.1.143/H264?ch=1&subtype=0 ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! xvimagesink

I would be glad if you could help.

@barslan16 Is there an HDMI monitor connected ? And on which platform are you trying to run this demo ?

@manoj7410 I am using rpi4 and coral, I could not run it when connected with hdmi, nor could I run it when connected via vnc player.
The brand of the camera I use: Qmax IP camera

Same problem here, i can get a feed with:

gst-launch-1.0 rtspsrc location=rtsp://admin:password@10.8.0.4:554/videoinput_1:0/h264_2/media.stm ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! xvimagesink

but following gives error:

python3 detect.py --tracker sort --videosrc rtsp://admin:password@10.8.0.4:554/videoinput_1:0/h264_2/media.stm

Warning: gst_parse_error: Delayed linking failed. (7): ./grammar.y(506): gst_parse_no_more_pads (): /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0:

Following works using laptop webcam:

python3 detect.py --tracker sort

Any help please????

[kiteklan]

try to remove the password auth. from the camera menu

[highfreq]

Tried without password, same error. Must be something in the pipeline that they build in the application that is broken because the following works:
gst-launch-1.0 rtspsrc location=rtsp://admin:password@10.8.0.4:554/videoinput_1:0/h264_2/media.stm ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! xvimagesink

[kiteklan]

Quick note gst-launch-1.0 rtspsrc location="rtsp://admin:xxxxx@192.168.1.105:554/cam/realmonitor?channel=2&subtype=0"
Using double quotes may help, I managed to run with this , but still issues with buffer

[highfreq]

Can't believe still the same problem after months. Could someone from google fix it please?

[jlpoolen]

I'm looking into this and noticed that the video used for the two methods (invoked with parameters: --device and --stream) differ... and they differ from the original presumably borrowed by Google from pixabay.

See http://salemdata.net/ai/coral/video_device_comparisons.html

I think the complexity of gstreamer and video, in general, is intimidating, even for the people supporting the functionality of the coral chip.

These dot diagrams representing runs of Google's default demonstration programs edgetpu_demo --stream and edgetpu_demo --device may be helpful in analyzing the flow:

It works for me :

python3 detect.py --videosrc "rtsp://192.168.120.58/ch01_sub.h264 ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert"

[jvsinclair]

I have the same issue. I was able to use ffmpeg / vlc to view the stream with no issue:

ffplay -i rtsp://1234:1234@192.168.123.31/live 

I then tried the various gst-launch commands, for example:

gst-launch-1.0 rtspsrc location="rtsp://1234:1234@192.168.123.31/live" ! videoconvert ! autovideosink

Every time, no matter the options selected, I get the following error:

WARNING: from element /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0: Delayed linking failed.
Additional debug info:
gst/parse/grammar.y(540): gst_parse_no_more_pads (): /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0:

Reading through some forums is seem that on Debian there are some issues with non-free code for RTSP so the decision was made to pull it: Debian bug #982299 . Not sure it its related, but a lot of the tools I tried to use in testing this ran into issues because of RTSP being pulled (like in VLC on debian).

Then I came across this old Stack overflow article so I tried it:

gst-launch-1.0 uridecodebin uri="rtsp://1234:1234@192.168.123.31/live" ! videoconvert ! autovideosink

and it works great

Based on that, here is how I fixed it. In gstreamers.py line 219, I updated it to useuridecodebin instead of rtspsrc

    elif videosrc.startswith('http'):
        PIPELINE = 'souphttpsrc location=%s'%videosrc
    #elif videosrc.startswith('rtsp'):
    #    PIPELINE = 'rtspsrc location="%s"'%videosrc
    elif videosrc.startswith('rtsp'):
        PIPELINE = 'uridecodebin uri="%s"'%videosrc
    else:
        demux =  'avidemux' if videosrc.endswith('avi') else 'qtdemux'

With that change you can use a password protected rtsp stream. Works with Wyze v3 camera running rtsp firmware and VLC running on Mac creating a rtsp stream. Needs to be tested more before creating a pull request with this change but it works on my Debian 11 server.
