禁用在libvlc Python中播放视频时打开新窗口

Question

我正在开发视频播放器，我想知道如何在新窗口中禁用打开和播放所选视频？有没有办法在原始窗口中打开它？我完全不知道该怎么做。谢谢大家。

如果你没有告诉libvlc要绘制到哪个窗口，它将自己创建一个并绘制它。

因此，如果您希望libvlc在应用程序的指定窗口中绘制，则需要根据您的主机平台告诉它：

• libvlc_media_player_set_hwnd在视窗上，
• libvlc_media_player_set_xwindowLinux 上，
• libvlc_media_player_set_nsobject苹果平台上。

有关所需的确切文档和参数，请参阅官方文档。由于您使用的是 Python，因此您应该在绑定中搜索这些 C 函数是如何从 Python 绑定中公开的。
