我在 Ubuntu 14.04 64 位中顺利构建了 Minitube 2.5.2,但无法播放任何视频。我已经安装了phonon, phonon-backend-vlc, phonon4qt5-backend-null, libphonon4, libphonon4qt5-4, python-qt4, libphonon4qt5-dev
。
当我尝试运行minitube
命令时,它显示以下错误:
$ minitube

我还需要什么?我该如何解决?谢谢。

我刚刚遇到了类似的问题,如下所述另一个问题。
经过几次尝试,我意识到 phonon qt5 有单独的软件包。
安装以下软件包解决了我的系统上的问题:
sudo apt install phonon4qt5 phonon4qt5-backend-gstreamer phonon4qt5-backend-vlc
现在,这些包的安装可能应该从 gwenview 包中推荐,所以这可能是一个打包错误。
