v4l2src on imx6 board

[张若]

Hi all,

Previously, I was working on camera video streaming on imx6 board with "imxv4l2videosrc" as source element. The drawback is that the "imxv4l2videosrc" can only afford specific 6 resolutions.

However, now I need to have more other customized resolutions. Then I am thinkling about using the "v4l2src" to support more flexible resolutions. BUT the v4l2src is not working and always showing errors.

If the "v4l2src" is capable to use on imx6 board?

Is there any conflicts between "imxv4l2src" and "v4l2src"?

Thanks in advance for your help!

Best regards,

Ruo

Have you tried using mfw_v4lsrc instead?

imxv4l2src should be used with the NXP provided kernel.

v4l2src should be used with mainline kernel + mainline Gstreamer.

There is a recent series from Steve Longerbeam (still under
review/rework) that adds support for the camera capture on mx6 running
kernel 4.10-rc:
https://github.com/slongerbeam/mediatree/tree/imx-media-staging-md-v9

I was able to test his series with Gstreamer 1.10.2 using the standard
v4l2src plugin.

mfw_v4lsrc seems only to be used with Gstreamer 0.1?

But I need to use Gstreamer higher than version 1.6.
