Force updating metadata cache

2020-09-16 14:05:32

I'm writing component that plays headless raw PCM files.
https://github.com/dofuuz/foo_input_raw

It plays file correctly. Changing preference affects playback as intended.

But file's information(Length, Sample rate, Channels, Bits per sample, Bitrate) is fixed to it's first load.
Changing preference won't update general file infos.

I tried to use decode_get_dynamic_info() but it does not update properties detail.

Is there any way to refresh/delete metadata cache on changing preference?
Or force updating on playback time?

Not unless you want to change the file's modification time. Or force the user to reload the info manually.

I cannot find menu entry to force reload from fb2k.
Should I add it to component? Is there any example for this?

Shift + Right click on the relevant tracks -> Tagging -> Reload info from file(s).
Pressing Shift might not be necessary depending on your settings for the context menu.

Actually you can force update cached metadata from code. I for example do that with External Tags. Not sure it's a good idea for a decoder but here's a piece of code to achieve it:

Code: [Select]

static void refresh_metadata(metadb_handle_ptr p_track, const file_info &p_info, const foobar2000_io::t_filestats p_filestats)
{
    if (p_track.is_valid()) {
        auto mio = metadb_io_v2::get();
        service_ptr_t<metadb_hint_list> hint_list = mio->create_hint_list();
        metadb_hint_list_v3::ptr hint_list_v3;
        hint_list_v3 ^= hint_list;
        hint_list_v3->add_hint_forced(p_track, p_info, p_filestats, true);
        fb2k::inMainThread( [=] {hint_list->on_done();} );
    }
}

In addition to the methods above, you can also assign a button to that action from your Customize Buttons context menu. Right-click your button bar, choose Customize Buttons, and in Available Commands expand context->tagging->reload info from files; "Add". Then you can just highlight file(s) and hit that button to do the metadata update.
