Function Documentation

◆ filter_AddProxyCallbacks()

void filter_AddProxyCallbacks ( vlc_object_t obj,
filter_t filter,
vlc_callback_t  restart_cb 
)

This function allow dynamically changing filter variables from a different object via VLC variables mapping.

It maps the filter's variables on the proxy objects and bind them with a var callback that forwards changes to the filter. This is especially useful for manipulating filter chains via a single parent object.

Parameters
objthe object to add the callback proxy to
filterthe filter object for which the callback will be proxified
restart_cba vlc_callback_t to call if the event means restarting the filter (i.e. an event on a non-command variable)
