Rtsp ошибка 451

Hello,

I am upgrading a project from Gstreamer 1.16.2 to the latest and greatest. However, I am using rtsp streams integrated via Milestone Xprotect (popular VMS) ONVIF bridge plugin (this plugin exposes onvif enabled rtsp urls). I’ve noticed that these streams are now failing during this upgrade. This issue I believe helped remedy some other issues i saw with /vod/ rtsp streams, but with live rtsp streams (which playback in vlc and older gst versions fine), I am now receiving a fatal Error (451): Parameter Not Understood error. I’ve attached logs of the following command in both versions.

GST_DEBUG=rtspsrc:6 gst-launch-1.0 rtspsrc location=»rtsp://username:pw@192.168.7.235:554/live/96813dab-2c0d-4308-b031-4fb1f668d9cf» protocols=tcp ! decodebin ! fakesink > rtspsrc_issue.log 2>&1

Since this requires a milestone server to test, I realize it may be difficult to address. I’m happy to coordinate with some temporarily if they’d like to test on my server (I can expose a public IP to a specific person for a short window if needed).

Gst 1.16.2: rtspsrc_issue_gst_1_16.log

Latest build of main branch as of last Friday: rtspsrc_issue.log

Thanks
Matt

If the stream on the link does not exist, creating VideoCapture object on that link would still be successful but you will not be able to process on the object.

You code’s control flow just might be going in and checking if (cap.isOpened()== True) but there is no else block to handle what would happen if if (cap.isOpened() != True). So just try adding an else block to display the error message.

for x in feedList:

    print("[INFO] Checking Link..." + x)

    cap=cv2.VideoCapture(x)

    try:   
        # Check if camera opened successfully
        if (cap.isOpened()== True): 
            streamlink = x
            print("[INFO] FOUND! Stream Link..." + x)
            break
        # Else is important to display error message on the screen if can.isOpened returns false
        else
            print("[NO STREAM]" + x)
    except socket.error:
        print("[NO STREAM]" + x)
    except:
        print("[FAILED]" + x)
        pass

If this doesn’t work: following might solve the issue:

One of the main issues is that every camera manufacturer uses their
own protocol (RTSP URI formatting). Finding the correct URL for your
IP-camera can be frustrating and time-intensive. When found you can
try to open it with VLC, and afterwards with Kerberos.io.

Depending on the format of the RTSP URI things can go wrong, for
example when using a format like above. To solve the problem you’ll
need to add an question mark «?» at the end of the url.

As example original link might be:

rtsp://192.168.2.109:554/user=admin&password=mammaloe&channel=1&stream=0.sdp

So with ? it would be:

rtsp://192.168.2.109:554/user=admin&password=mammaloe&channel=1&stream=0.sdp?

Thanks for the reply. With the ffplay test I get the following result

Further research shows that ffplay (and ffmpeg) view rstp as a demuxer and need more command line options. I tried the following

ffplay -rtsp_transport tcp -f rtsp rstp://192.168.1.XX:554/user=admin&password=XXXXXXXXXXXX&channel=1&stream=0.sdp?real_stream—rtp-caching=100

This returns

So I am getting somewhere. Where can I put the ffmpeg arguments in cctv-viewer?
