Hi Carl,

As required please find the attached file.
I have shared the console command (copied from the CMD prompt) and Batch
file in notepad(.bat file to call the ffmpeg.exe file) . Unable to attach
the error log file because it is empty(0 bytes)

File1: Console_CMD[1] : command copied from the command prompt in
Notpad(text format).
File2: BatchFile(FFmpeg call) : Copied batch file command in Notepad(text
format)

Regards,
Saurav
