RTSP connection issue

[YoungjaeDev]

hello I am testing with a new RTSP camera, which has the feature of requiring id/passwd. (like std::wstring rtsp_camera_path = L"rtsp://admin:1234@192.168.0.41:554/Ch1";

But in conclusion, connection does not work in DSL. h264 depay and parse work, but it seems like something isn't supported behind the scenes.

system: dGPU with docker DS: 6.2 commit: v0.27.b.

previous state = DSL_STATE_PAUSED, new state = DSL_STATE_PLAYING

I tried using the same RTSP camera with a lower resolution (different channel), but it doesn't work on DSL. It works on the basic deepstream base I wrote, but the GST_Warning below appears and operates with low performance....

@youngjae-avikus When you are entering your credentials as username@password, is there any chance that either the username or password has any special characters in it, such as ( / ? @ %) ?

[rjhowell44]

I've done a lot of searching on this... there were a number of posts on the NVIDIA boards, but with no answers. this was the only hint I could find which is why I'm asking about the special chars https://github.com/Kurento/bugtracker/issues/554

No. I used admin / 1234 However, @ is inserted between passwd and ip.

[rjhowell44]

That should be ok... it is just if you have @ in the password or user id.

There are a number of threads on this subject, none that offer much help. For example, see https://github.com/bluenviron/mediamtx/issues/1019

Could you try capturing a pipeline graph? I'd like to see the connection between the rtpsrc->parser->depay->decoder

Well, actually, the deepstream version that contains the face recognition module I developed is 6.1.1. I think it's worth upgrading the version and testing it out. The other module I tested separately was 6.2 (which worked somewhat normally but low performance). I'll take some time to test it and share it with you.

@rjhowell44

deepstream 6.2 jetson orin agx devkit code: example/cpp/rtsp_connection.cpp

Still getting the same error

[YoungjaeDev]

@rjhowell44 Here it is mydot

When analyzing issues on the forum, it seems there is something to do with nvv4l2decoder and pasebin. It doesn't seem to have anything to do with id/passwd.
