Unbind the media player handle

Postby neosettler » 28 Jan 2019 00:07

Greetings,

Is there a way to unbind libvlc_media_player_set_hwnd handle to it's default state, if any? I'd like to change from an output to a window handle to a render to texture while playing the same video.

So far, setting libvlc_media_player_set_hwnd to null doesn't seem to have any effect.

also, could this be detached as well? Removing the callbacks that is.

Code: Select all

libvlc_video_set_format_callbacks(m_VLC_Player, ZVideoLandMovie::CallbackSetup, ZVideoLandMovie::CallbackCleanup);

What kind of effect are you expecting? Setting it to null stops VLC from using that HWND to draw I believe.

Try calling libvlc_video_set_format_callbacks with NULL arguments? If that doesn't work, dispose of your mediaplayer and create a new one?

Stop the media player instance, delete it and create a new one.

Good idea, delete and create works!

One remaining issue with this approach is that using Qt::QWidget::windId as a render target, the QWidget does not refresh after deleting a media player that was using its handle. Seems like the winId (handle) is being messed with somehow. Any hint would be much appreciated.
