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 ...

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:

Hello Mauricio Karrei
I got the exact same problem as you. What is the difference between the old one with the new one?
Could you please share the solution?
Thank you
