내가 video6를 추측 엔티티 12에서 시작합니다. 다음과 같은 media-ctl 명령을 주려고했지만 작동하지 않습니다.
$ media-ctl -r -l '"mt9v032 3-005c":0->"OMAP3 ISP CCDC":0[1], "OMAP3
ISP CCDC":2->"OMAP3 ISP preview":0[1], "OMAP3 ISP preview":1->"OMAP3

내가 어떤있는 GStreamer 파이프 라인을 실행하려고하면,이 명령을주고 나서, 나는 다음과 같은 오류 얻을 :
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Failed to enumerate possible video formats device '/dev/video6' can work with
...
는Failed to get number 0 in pixelformat enumeration for /dev/video6. (25 - Inappropriate ioctl for device)
는 사람이 어떻게 나를 보여줄 수를 적절한 media-ctl 명령을 설정하십시오.
