This series includes two parts:
- Support for controls with string type from Laurent
- Support for V4L2 U8 controls with paylod from me.
The series starts with a rename of ControlRange to ControlInfo as for string
controls 'range' is not appropriate, then support for controls with type
std::string is added to the control and control serializer frameworks.
After a small fix for the V4L2Device::ioctl() return code, the series enables
reading/writing V4L2 controls with type V4L2_CTRL_TYPE_U8 and enable their
enumeration in the v4l2 control framework.
A test for both use cases is added.
Series is based on the latest master branch.
Thanks
