[FFmpeg-user] Integration of ffmpeg

[The Admin]

Hello,

  I have been using your command line tool and it works fine to mix audio
files and video files.  I am trying to automate the command tool using C#
and it just hangs.  When I copy the command into a CMD window, it works
fine.

Specifically, I am using the amix command to combine multiple audio files
(m3u8)  that have different start times.

  Can you help me with this?

Thanks,
Marc.
