Comment (by ramitbhalla):
Sure: The FFMPEG Documentation page: (quoting)
Section 4.1
A stream specifier is a string generally appended to the option name and
separated from it by a colon. E.g. -codec:a:1 ac3 option contains a:1
stream specifer, which matches the second audio stream. Therefore it would
select the ac3 codec for the second audio stream.
Section 4.4
ffmpeg -i INPUT -map 0 -c copy -c:v:1 libx264 -c:a:137 libvorbis OUTPUT
will copy all the streams except the second video, which will be encoded
with libx264, and the 138th audio, which will be encoded with libvorbis.
What i understang from the above is once I select the stream identifier it
will apply the following codec to it. Did I get it wrong?
