 Hi Team,

 I am trying to transcode a file. And getting the following output, while
 integrating with the application I am getting this as an error output. The
 confusion here is:

 1. Is there a problem with the audio file (attached the original one)?

 2. FFMpeg is returning a non-zero value by mistake.

 I am attaching the original audio file for your reference.

 C:\Users\himanshu.bhardwaj>ffmpeg -y -i _contents.wav -acodec pcm_mulaw
