V4l2 is not Supported #156
Comments

Please, properly format code before posting it here.. Also, whats the output of the v4l utils compliance test? |
|
I have updated the formatting and also added the v4l utils compliance test report to the original post. |
|
Hi,
If you are using playbin, please use these flags: I think you might have misread the error: Use: Regards, .signature not found |
|
I still get the same error message after using the flags you mention. I also built the gstreamer with the changes suggested by memeka, still the same issue. |
|
This issue is closed but I do not know of the solution can you please add any references to the solutions. |
