答案1
可能需要从源安装 MLT 渲染引擎
git clone git://github.com/mltframework/mlt.git
cd mlt
配置
./configure --prefix=/usr --enable-gpl
或者，如果 qimage 模块配置失败，请尝试：
./configure --prefix=/usr --enable-gpl --qimage-libdir=/usr/lib/ --qimage-includedir=/usr/include/qt4
编译代码
make clean make -j3 sudo make install
git tag -l
git checkout tag (origin/master)
最后尝试用终端命令打开
sudo kdenlive或者kdenlive
这对我有用
