:::: My goal is to copy both video streams without any change.

This command comes close:

     ffmpeg -y -i 30sec-test.skype.mov -an -map 0.2 -map 0.3 \
            -vcodec copy -vcodec copy 30sec-test.video.mov -newvideo

Except the second stream in the output video has changed codecs...

:::: Maybe there's additional syntax for -map to do the copy correctly.

Pass along suggestions.

Thanks.
