Description Florent Thiéry 2016-12-23 16:37:25 UTC 
This pipeline fails:
gst-launch-1.0 videotestsrc ! "video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080, framerate=(fraction)30, colorimetry=(string)bt2020" ! videomixer !  "video/x-raw, format=(string)NV12, width=(int)3840, height=(int)2160, framerate=(fraction)30, colorimetry=(string)bt2020" ! fakesink
ERREUR : de l’élément /GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0 : Internal data stream error.

Also fails:
gst-launch-1.0 videotestsrc ! "video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080, framerate=(fraction)30, colorimetry=(string)bt2020" ! videomixer !  "video/x-raw, format=(string)NV12, width=(int)3840, height=(int)2160, framerate=(fraction)30, colorimetry=(string)bt601" ! fakesink

Oddly, this works:
gst-launch-1.0 videotestsrc ! "video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080, framerate=(fraction)30, colorimetry=(string)bt2020" ! videomixer !  "video/x-raw, format=(string)NV12, width=(int)3840, height=(int)2160, framerate=(fraction)30, colorimetry=(string)bt709" ! fakesink
