I'm currently running Fedora 31 (Debian unstable should provide the
same), with the stock GStreamer 1.16.1. And doing playback with:
gst-play-1.0 Videos/bbb_sunflower_1080p_30fps_normal.mp4 --videosink="kmssink" --flags=video
With this player, you can seek with the arrows (left/right), or go back
to the start using 0 key. When you seek, the streaming stalls. If you
switch the --videosink to fakevideosink as an example, seeking works
perfectly, and kernel does not complain anymore. Same if you don't use
a zero-copy path, like fbdevsink.
