Hi, community.


I tried to receive and display a RTSP Streaming from ip camera on i.MX6Q SABRE.

I tried the following GStreamer pipeline, and some cameras works fine.


# gst-launch-1.0 rtspsrc location=rtsp:// ! rtph264depay ! vpudec ! overlaysink overlay-top=384 overlay-left=512 overlay-width=512 overlay-height=384 sync=false


But on a specific camera, the following error has happened, and could not run the GStreamer.

The error is Internal data flow error, and it seemed pipeline is not linked.

Anyone know, how to solve this problem?
