I'll test it and report back. <br /><br />I tried "add-borders" with videoscale and didn't seem to work ?<br /><br /><a href="https://gstreamer.freedesktop.org/documentation/videoscale/index.html?gi-language=c">https://gstreamer.freedesktop.org/documentation/videoscale/index.html?gi-language=c</a><br /><br /><br /></div>

<div>I am using kmssink to output video to HDMI on RPI. However, the video is overlaying the console text, with the text showing underneath it depending on the video scale. <br /><br />In 16:9 on a TV it still shows text top and bottom but not on my monitor. In 4:3 it's apparantly forcing aspect ratio, and the console text is displaying underneath it . <br /><br />Is there a way to force a black border using playbin ?<br /></div></blockquote></div></div><div dir="auto"><br /></div><div dir="auto">By default, kmsink will render on an overlay, leaving fbcon frame buffer in place. To add black border without loosing the speed of zero copy, kmssink would need to learn to render on multiple planes, and for that it would need to use the new atomic kernel API. We basically need to implement a small compositor to go further with that.</div><div dir="auto"><br /></div><div dir="auto">Meanwhile, you could disable fbcon, or try to set force-modesetting property (that does not always work though).
