我想video6是从实体12开始的。我尝试给出以下媒体-ctl逗号，但它不起作用。

代码语言：javascript
复制
$ 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
ISP resizer":0[1], "OMAP3 ISP resizer":1->"OMAP3 ISP resizer
output":0[1]'

$ media-ctl -V '"mt9v032 3-005c":0[SGRBG10 752x480], "OMAP3 ISP
CCDC":2[SGRBG10 752x480], "OMAP3 ISP preview":1[UYVY 752x480], "OMAP3
ISP resizer":1[UYVY 752x480]'

在给出这些命令之后，当我尝试运行任何Gstreamer管道时，我会得到以下错误：

代码语言：javascript
复制
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

..。

代码语言：javascript
复制
Failed to get number 0 in pixelformat enumeration for /dev/video6. (25 - Inappropriate ioctl for device)

有人能告诉我如何设置正确的媒体ctl命令吗？

确保使用gstreamer http://docs.gstreamer.com/display/GstSDK/Basic+tutorial+11%3A+Debugging+tools中的调试信息。

为了使流正常工作，我不得不修补gstreamer和omap isp，但是使用测试视频源，已经可以测试管道了。

我使用Overo和DM3730，caspa和tobi/palo35 35/栗子
