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?
