When I display a 4:3 aspect ratio video in a 16:9 display screen in fullscreen, the result display shows bright green sidebars OR places the 4:3 video in a random location within the larger display.
How to remove the green sidebars?
Or, How to center the video in the display?
GStreamer 1.14.4 on Intel Cherrytrail hardware on Debian GNU/Linux 9 (stretch).
Same results with vaapisink or waylandsink.
Same results with "fullscreen=true" or setting the sizes explicitly via videoscale or vaapipostproc.
Example pipelines:
Green sidebars:
gst-launch-1.0 videotestsrc ! vaapipostproc width=1920 height=1440 ! vaapisink fullscreen=true
Green sidebars:
gst-launch-1.0 videotestsrc ! video/x-raw, width=1920, height=1440 ! vaapisink fullscreen=true
Dark sidebars (good), but can't horizontally position the window (bad):
gst-launch-1.0 videotestsrc ! video/x-raw, width=2880, height=2160 ! vaapisink
Dark sidebars (good), but can't horizontally position the window (bad):
gst-launch-1.0 videotestsrc ! video/x-raw, width=2880, height=2160 ! waylandsink
Videobox removes green sidebars (good), but performance hit (bad):
gst-launch-1.0 videotestsrc ! vaapipostproc width=1920 height=1440 ! videobox left=-320 right=-321 top=-1 ! vaapisink fullscreen=true
Videomixer provides similar performance degradation to Videobox as would be expected.
Does anyone know how to remove the green bars without degrading performance?
Thanks!
