[gst-devel] How to create a delay in a video stream?

[Francis Rammeloo]

I have a pipeline that receives a camera video stream over USB and a
screen capture video over RTP. The incoming streams are combined using
the videomixer element. The desktop streamer seems lag 2 seconds
behind the camera stream. I would like to correct this time difference
by intruducing a delay of 2 seconds for the camera. How can I do this?

Grts,
Francis

Maybe you can add a queue after the camera source and use "min-threshold-time"
(or "min-threshold-buffers" where one buffer = one frame).

You want to use the min-threshold-time of the queue element:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-queue.html#GstQueue--min-threshold-time

Keep in mind that queueing a decoded video stream might result in huge
memory usage. Since you are storing the video between current and delay.
