Unable to view stream using vlc - "Failed to connect", "Failed to setup RTSP session"

[ctrager]

Neolink itself seems to be working but I"m unable to view the stream using VLC as a client. This is with a Reolink E1 camera. I can connect to the camera with the reolink app.

Neolink seems to work:

./neolink --config my_config.toml
[2020-07-18T19:53:23Z INFO  neolink] Neolink 0.3.0 (unknown commit) release
[2020-07-18T19:53:23Z INFO  neolink] one: Connecting to camera at 10.0.0.21:9000

[2020-07-18T19:53:23Z INFO  neolink] one: Connected to camera, starting video stream subStream

My config:

bind = "0.0.0.0"

[[cameras]]
name = "one"
username = "admin"
password = "MY PASSWORD"
address = "10.0.0.21:9000"

My vlc command line:
vlc rtsp://127.0.0.1:8554/one
My vlc log:

live555 error: Failed to connect with rtsp://127.0.0.1:8554/one
satip error: Failed to setup RTSP session

Do I need more vlc command line flags?

For an E1, you need to let Neolink know it's H.264, because it can't yet autodetect this.

This needs to be clearer in the docs.

Try:

bind = "0.0.0.0"

[[cameras]]
name = "one"
username = "admin"
password = "MY PASSWORD"
address = "10.0.0.21:9000"
format = "H264" # <<< Add this line

Works!

I'd like to reopen this issue.

Same problem with same camera, but different neolink version on docker.

According to the logs - with the workaround from above - I see

[2023-01-07T22:09:48Z INFO neolink] Neolink 0.4.0 (unknown commit) release
[2023-01-07T22:09:48Z WARN neolink::rtsp] The format config option of the camera has been removed in favour of auto detection.

The camera works perfectly via neolink in Home Assistant. So the configuration and neolink for the camera works. But not with VLC.

Firmware version of the camera is v3.0.0.115_20102200

@mailq Your issue is different then this one. Please open a new issue. If it's working on ha which uses ffmpeg I think but not vlc then the most likely cause of your issue is the vlc udp buffer size not being big enough.

I have the same problem as ctrager however adding the "format" in the config did not fix it for me.
The command "vlc rtsp://127.0.0.1:8554/arlon" outputs the following error "satip stream error: Failed to setup RTSP session". I managed to make it work by using ffplay instead of vlc: "ffplay rtsp://127.0.0.1:8554/arlon"

specs: ubuntu 22.04, vlc version VLC media player 3.0.16 Vetinari (revision 3.0.13-8-g41878ff4f2).

@hupratt ctranger's issue was that there camera used h264 formatted video and at the time of that issue (3 years ago) we did not automatically detect and swap to the right decoder. Now (for about 2 years now) we do detect and swap the format automatically. So:

1. Format option does nothing as we auto detect now

2. Your issue theresfore cannot be the same and must be for another reason. (New issue please no need to reopen a 3 year old closed issue)

3. You can play in ffprobe and ffplay which means this is to do with the way the rtsp server and client (vlc) are talking with each other. We outsource all rtsp details to gstreamer so perhaps this this the rtsp format not passing vlc standards.

My fork https://github.com/QuantumEntangledAndy/neolink uses updated gstreamer. Please try that one and maybe open a new issue after that.
