问题
I am using the moviepy module with python 3.2 on my RPi 2. It uses FFMPEG to read and write the video, so I installed FFMPEG using these instructions to the letter. Now when I run the program, it says that my video export failed because FFMPEG didn't find the libmp3lame codec that it needs. How do I got about installing the libmp3lame codec onto my RPi 2 (running Raspian Wheezy)?
I think I have to reinstall FFMPEG to install the codec.. how do I do that correctly?
回答1:
First, install lame mp3 with
sudo apt-get install libmp3lame-dev
and then recompile/build ffmpeg including the --enable-libmp3lame flag
./configure <other-configure-options> --enable-libmp3lame
