128 * This is a global list of existing decoders.
129 * The reason for this list is that:
130 * - I want to be able to reconfigure Tiger when user prefs change
131 * - User prefs are variables which are not specific to a decoder (eg, if
132 * there are several decoders, there will still be one set of variables)
133 * - A callback set on those will not be passed a pointer to the decoder
134 * (as the decoder isn't known, and there could be multiple ones)
135 * - Creating variables in the decoder will create different ones, with
136 * values copied from the relevant user pref, so a callback on those
137 * won't be called when the user pref is changed
138 * Therefore, each decoder will register/unregister itself with this list,
139 * callbacks will be set for the user prefs, and these will in turn walk
140 * through this list and tell each decoder to update the relevant variable.
142 * VLC's variable system is still in my way as I can't get the value of
143 * the user pref variables at decoder start *unless* I create my own vars
144 * which inherit from the user ones, but those are utterly useless after
145 * that first use, since they'll be detached from the ones the user can
146 * change. So, I create them, read their values, and then destroy them.
