rspngenc: Corrupted images after first frame
Example command
gst-launch-1.0 videotestsrc is-live=false num-buffers=10 ! videoconvert ! video/x-raw, format=RGB, width=160, height=120 ! rspngenc compression-level=2 filter=4 ! multifilesink location="out/frame%d.png"
First frame works, but every frame after that is corrupted.
