add a configuration file...
Created by: nicosang
in order to evolve the behavior of the video player without build it. It could be useful to allow users to change video player parameters just using json configuration file. If the idea is accepted, we could add others parameters to this config file.
the configuration file is organized into 3 parts :
- global parameters
- video parameters
- audio parameters
A parameter could be defined in, for instance, 2 parts. In this case, the parameter defined in the specific part will be used in place of the global one.
