Hello! I am trying to run the [rtsp-streaming example](https://github.com/luxonis/oak-examples/tree/main/streaming/rtsp-streaming) on standalone mode using vlc. Wireshark shows: 1. VLC sends SETUP to rtsp://cameraip:8554/preview 2. Camera responds 200 Transport: RTP/AVP;unicast;client_port=9006-9007;server_port=34784-34785;ssrc=9F994EA5;mode"PLAY" Server: GStreamer RTSP server Session Date 3. VLC requests PLAY rtsp://cameraip:8554/stream=0 4. Camera responds 404 not found. I'm wondering is all the gstreamer goodness not coming along for the ride when this gets ran as an oakapp on the camera? the oakctl app logs dont show much interesting just oak_webrtc not ready missing creds from agent and system time 1970 issues. I manually set system time on the camera. unsure if this is coincidence but now 5. VLC requests OPTIONS 6. camera responds with 200 Public: OPTIONS, DESCRIBE, ANNOUNCE, GET_PARAM, Pause, PLAY, RECORD, SETUP, SETPARM, TERADOWN 7. camera fin acks and connection tearsdown.

Hey johnmiller - GStreamer is present in standalone mode here. The oakapp installs gst-rtsp-server, and the backend starts a GStreamer RTSP server that mounts only /preview.

So the key clue is this:

SETUP rtsp://cameraip:8554/preview -> 200
PLAY rtsp://cameraip:8554/stream=0 -> 404
That suggests an RTSP URL/control-path mismatch with VLC, not that GStreamer is missing. The example only exposes /preview, not /stream=0.

The oak_webrtc / bad time logs are likely unrelated to plain RTSP.

As a quick sanity test, try ffplay rtsp://cameraip:8554/preview. If ffplay works, the server is basically fine and this is VLC interop.

Thanks,
Oksar

Works with ffplay! Looks like ffplay is tolerant in comparison to VLC.
