视频无缝播放

Question

self.playlist = QMediaPlaylist()  
self.playlist.addMedia(QMediaContent(QUrl.fromLocalFile("resources/0_2.mp4")))
self.playlist.addMedia(QMediaContent(QUrl.fromLocalFile("resources/0_3.mp4")))
self.playlist.addMedia(QMediaContent(QUrl.fromLocalFile("resources/0_4.mp4")))
self.playlist.addMedia(QMediaContent(QUrl.fromLocalFile("resources/0_5.mp4")))
self.playlist.addMedia(QMediaContent(QUrl.fromLocalFile("resources/0_6.mp4")))
self.playlist.setPlaybackMode(QMediaPlaylist.Sequential) 
self.player_2 = QMediaPlayer()
self.player_2.setVideoOutput(self.ui.video_page_2)
self.player_2.setPlaylist(self.playlist)

我有很多视频要播放，但是视频切换过程中黑屏很短。

如何无缝播放视频？
