No Signals in mdk::Player about mdk-sdk HOT 5 CLOSED

you have to emit signals yourself in the callback. see https://github.com/wang-bin/qtmultimedia-plugins-mdk/blob/master/mediaplayercontrol.cpp#L44 https://github.com/wang-bin/qtmultimedia-plugins-mdk/blob/master/mediaplayercontrol.cpp#L47

from mdk-sdk.

i have tried the following from the above link, but its still not working

_player->onStateChanged([this](State value){
Q_EMIT stateChanged(value);
});
_player->onMediaStatusChanged([this](MediaStatus value){
Q_EMIT mediaStatusChanged(value);
return true;
});

from mdk-sdk.

how do you connect signals?

from mdk-sdk.

i tried this first but it didn't work
connect(player,&MediaPlayer::mediaStatusChanged,this,&MainWindow::mediaStatusChanged);

then i tried this, it also didn't work connect(player,SIGNAL(mediaStatusChanged()),this,SLOT(mediaStatusChanged()),Qt::DirectConnection);

from mdk-sdk.

connect(player,&MediaPlayer::mediaStatusChanged,this,&MainWindow::mediaStatusChanged);

It's a queued connection, signal parameter type MediaStatus must be known to qt metatype system.

    Q_DECLARE_METATYPE(mdk::MediaStatus) // declare in global scope

   qRegisterMetaType<MediaStatus>(); // in a function

connect(player,SIGNAL(mediaStatusChanged()),this,SLOT(mediaStatusChanged()),Qt::DirectConnection);

forgot signal parameter? qRegisterMetaType too.

other options can be

    connect(this, & MediaPlayer::mediaStatusChanged, []{});

from mdk-sdk.
