Friends:<br><br>Some of you are audio video experts. I want to pick your brains. <br><br>I have a video file AustrianAlpsTyrol.mpg that I recorded from PBA (Rick Steves)<br><br>It is a good recording with Mono audio.(aka left channel only)<br>
<br>I was able to extract audio from the .mpg file I used ffmpeg.<br><br>I need help in the steps<br><br>a. Remove Audio from the original mpg file.<br><br>b. Copy Left channel to right channel of the audio (aka make Mono to Stereo).<br>
I am told that SOX does this but not sure how.<br><br>c. Put the Stereo audio back to the mpg file.<br><br>Any inputs on where to find this info is appreciated.<br><br>-Narahari<br>
