如何获得 FFMPEG Progress 以创建进度条？

Question

I'm trying to create a simple GUI for ffmpeg but am having problems getting the progress of a command. I'm using PySide as the GUI toolkit and I'm also using python3. I'm using QProcess to run the command and would just like to be able to create a progress bar.

EDIT: Preferably I'd like to use QProgressDialog: http://www.pyside.org/docs/pyside/PySide/QtGui/QProgressDialog.html

You are not going to have a very nice API over a process spawn interface. Moreover, it could be unstable.

Instead, you should be using Python bindings to libavcodec and other FFMPEG libraries. There are plenty of those on the web .
