The purpose of the rmt_translator_set_context() call is obvious: this function sets the strip handle as the translator context. Later, in the _rmt_adapter() function, which is called by the translator, we get this descriptor using rmt_translator_get_context(), find out the contents of the "brightness" field and automatically apply it using scale8_video(). |
