Comment (by msiders):

 Hi Gyan,

 With your suggestion:

 {{{
   ffmpeg \
  -f mpegts -i file.ts \
  -filter_complex "[i:100]split[out0][out1]" \
  -map [out0] -map [out1] -map i:101 \
  -c:2 copy \
  -f mpegts file-out.ts
 }}}

 you only put the audio without processing in the output. The other two
 video streams are re-encoded!

 Regarding the sentence: "A filtered stream cannot be streamcopied".
 I know that this is true at time. But it has sense in several scenarios.
 For example: If you like to do some processing but leave a copy of the
 original stream in the output.

 Please, don't mark this as "invalid". Almost put it as "enhancement".
 Thank you!
