Distorted video when using videoflip, videoscale and a video with image-orientation tag
Locked
 
|
I'm having problems displaying portrait orientation videos that have an
image-orientation tag (rotate-90). To automatically rotate the video I'm using videoflip (method=automatic). My video has a resolution of 1080x1920 and I want to scale it down to 540x960. But gst-launch shows a distorted image: gst-launch-1.0 -v playbin uri=file:///home/dmsch/portrait-fhd.mp4 video-sink="videoflip method=automatic ! videoscale ! video/x-raw,width=540,height=960 ! ximagesink" Screenshot: https://imgur.com/a/XRvh6ZN Video: https://drive.google.com/file/d/1mYWEpHsWQljhBGlBB4RPgDe8qAuKm3r_/view?usp=sharing -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

You should notice in the CPU load the difference. It's a very common trap.

Thanks for your answer, unfortunately adding pixel-aspect-ratio=1/1 to the
caps does not solve the problem. I used the following command: gst-launch-1.0 -v playbin uri=file:///home/dmsch/portrait-fhd.mp4 video-sink="videoflip method=automatic ! videoscale ! video/x-raw,width=540,height=960,pixel-aspect-ratio=1/1 ! ximagesink" Nicolas Dufresne-5 wrote > Le vendredi 11 décembre 2020 à 03:24 -0600, domsch a écrit : >> I'm having problems displaying portrait orientation videos that have an >> image-orientation tag (rotate-90). >> To automatically rotate the video I'm using videoflip (method=automatic). >> My video has a resolution of 1080x1920 and I want to scale it down to >> 540x960. >> >> But gst-launch shows a distorted image: >> gst-launch-1.0 -v playbin uri=file:///home/dmsch/portrait-fhd.mp4 >> video-sink="videoflip method=automatic ! videoscale ! >> video/x-raw,width=540,height=960 ! ximagesink" > > You need to specify an aspect ratio: > > video/x-raw,width=540,height=960,pixel-aspect-ratio=1/1 > > I don't remember why ximagesink does not force squared pixel aspect ratio, > there > wa a reason, but by fixing the aspect ratio you prevent videoscale from > scaling > that field rather then actually doing the scaling job.
