green artifacts at start, h264 rtsp

[Swen Kooij]

Hello everyone

We’re using the gstreamer rtsp plugin (gst-rtsp-server) and gst-launch to play a H.264 video stream from a security camera. We’ve configured the RTSP server to share the streams.

However, when I open a stream using gst-launch, I observe a green overlay (looks like artifacts) that is displayed for about 1-2 seconds and then the stream becomes visible and everything is normal and there are no artifacts during the remainder of the stream.

On the server we are using the following pipeline description:

( rtspsrc latency=150 location=rtsp://10.0.10.64/ONVIF/MediaInput?profile=bb_h264_256 ! queue ! rtph264depay ! rtph264pay name=pay0 pt=96 )

And we are starting gst-launch like this:

gst-launch-1.0.exe rtspsrc location=rtsp://localhost:8554/1_bb_h264_512 latency=0 buffer-mode=auto ! decodebin ! autovideosink

Does anyone know what is the cause of this and how we might resolve it? I’ve attached a screenshot to clarify what we observed.

Thank you in advance.

Met vriendelijke groet, Sincerely,
