676 | |
|
|
677 | These methods wrap a registry system around F<mpv>'s C<observe_property> |
|
|
678 | and C<observe_property_string> commands - every time the named property |
|
|
679 | changes, the coderef is invoked with the C<$mpv> object, the name of the |
|
|
680 | property and the new value. |
|
|
681 | |
|
|
682 | For a list of properties that you can observe, see L<the mpv |
|
|
683 | documentation|https://mpv.io/manual/stable/#property-list>. |
|
|
684 | |
|
|
685 | Due to the (sane :) way F<mpv> handles these requests, you will always |
|
|
686 | get a property cxhange event right after registering an observer (meaning |
|
|
687 | you don't have to query the current value), and it is also possible to |
|
|
688 | register multiple observers for the same property - they will all be |
|
|
689 | handled properly. |
|
|
690 | |
|
|
691 | When called in void context, the observer stays in place until F<mpv> |
|
|
692 | is stopped. In any otrher context, these methods return a guard |
|
|
693 | object that, when it goes out of scope, unregisters the observe using |
|
|
694 | C<unobserve_property>. |
|
|
695 | |
|
|
696 | Example: register observers for changtes in C<aid> and C<sid>. Note that |
|
|
697 | a dummy statement is added to make sure the method is called in void |
|
|
698 | context. |
