<div>Can you do the following command on the file that has the audio go away? : </div>
<div><br /></div>
<div>ffprobe -i file.ts</div>
<div><br /></div>
<div><br /></div>
And post the results in a reply. I want to see how the audio streams get defined by ffmpeg.

When I was watching the encoding, I could see that audio was reported as zero bytes<br /></span></p>
