Hi Carl,
I am new in ffmpeg community.
May be you are write but the code works fine there is no issue,
while writing the audio data no error. Only the output file has no audio
but in file properties it shows the audio bitrate, sample rate...
Can you suggest something so the issue will get resolved. ..
Thanks for suggestion.
