How to separate them? divided into two windows, let the left and right camera images are displayed separately?
回答1:
You will probably have to use a tee and two videocrop elements to cut out the pictures.
回答2:
The solution provided is next. Using a width=1280, height=480 videotestsrc the cropping could be done using videocrop plugin and a tee.
gst-launch-1.0 videotestsrc pattern=0 ! video/x-raw, width=1280, height=480 ! tee name=t ! videocrop left=640 ! queue ! ximagesink t. ! videocrop right=640 ! queue ! ximagesink
In gstreamer 0.10, the pipeline would be next:
gst-launch-0.10 videotestsrc pattern=0 ! video/x-raw-yuv, width=1280, height=480 ! ffmpegcolorspace ! tee name="t" ! videocrop left=640 ! queue ! ximagesink t. ! videocrop right=640 ! queue ! ximagesink
The original source is the SMPTE color bars from the videotestsrc. The resulting crop is shown in the next link. Adjusting it to your needs, you should have your two separated video images.
