[solved]imx6 USB Camera

[mauriciokarrei]

Hi,

I'm trying build an image yocto with gstreamer. I added on local.conf file the IMAGE_INSTALL_append:  "gst-plugins-base-meta gst-plugins-good-meta gst-ffmpeg gst-fsl-plugin" modules, and executed the process from this link: https://community.freescale.com/docs/DOC-93688

The output from the command  "gst-launch v4l2src ! mfw_v4lsink" is:

root@cgtqmx6:~# gst-launch v4l2src ! mfw_v4lsink

MFW_GST_V4LSINK_PLUGIN 3.0.11 build on Jul 30 2015 17:48:50.

Setting pipeline to PAUSED ...

ERROR: Pipeline doesn't want to pause.

ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Cannot identify device '/dev/video0'.

The device is not creating the /dev/video0. To create a new /dev/video0 I'm executing the command "mknod /dev/video0 c 81 0". After it, the output from the command "gst-launch v4l2src ! mfw_v4lsink" is:

Problem solved. I bought a new USB Camera with another driver. It's work perfectly.

Thank you so much.

Hello Mauricio Karrei
