 You need to have a `ffmpeg` binary to run `ffmpeg`. So far you haven't
 provided any method for us to duplicate the issue, and we have no idea how
 FFmpeg is involved here. Are you using the FFmpeg libraries, or are you
 somehow using the `ffmpeg` cli tool (although if you are it appears not to
 be in your `PATH`)?

 I'm assuming you're using the libraries because you mentioned something
 called "FFmpegDemo", but we do not support third-party tools. Testing with
 a recent `ffmpeg` binary will more easily show if the issue is valid here.

 You have to eventually stop the command. Because we do not have access to
 your input, creating a sample file can possibly be used as an alternative
 input to attempt to duplicate the alleged issue.
