The process could not be started. Either the is called program is not installed, or the ffmpeg or avconv call Faulty or you have not over sufficient permissions to to the program.

答案1

可能它会ffmpeg调用avconv

尝试这个：

sudo ln -s /usr/bin/avconv /usr/bin/ffmpeg

答案2

Ubuntu 14.04 可以使用 avconv，但不能使用 ffmpeg。删除 ffmpeg。删除 vokoscreen 并重新安装。
