imagefreeze

The imagefreeze element generates a still frame video stream from the input. It duplicates the first frame with the framerate requested by downstream, allows seeking and answers queries.

Example launch line

 gst-launch-1.0 -v filesrc location=some.png ! decodebin ! videoconvert ! imagefreeze ! autovideosink

This pipeline shows a still frame stream of a PNG file.
