export QT_DEBUG_PLUGINS=1
开启的情况下, 可以查看缺少什么动态库.
我的电脑是缺少 libgstreamer-0.10.so.0,
所以确保以下库的安装
gstreamer0.10-plugins-bad
gstreamer0.10-plugins-base
gstreamer0.10-plugins-good
gstreamer0.10-plugins-ugly
gstreamer0.10-pulseaudio
gstreamer0.10-x
libgstreamer0.10-0
libgstreamer0.10-dev
安装过程中少什么依赖就装什么依赖
libtag1-vanilla
libtag1c2a
libsidplay1
其中 libpng12 这个依赖
sudo add-apt-repository ppa:linuxuprising/libpng12;
sudo apt update;
sudo apt install libpng12-0;
