• added 3 functions form David's promts GPT generated code

  • func findFFmpegExecutable() (string, error)
  • func convertMusicFile(filename string, bitRate int) error
  • func parseBitrate(output string) int

• current status:

  • it works when codec info is removed from the ffmpeg command:
  • however the command codec info works when ffmpeg command called via terminal
  • need to explore further

• issue - when codec is added to the command these errors are returned:
