 Hi,

 I am using the last version available for Ubuntu 16.04

 As explained here:
 https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs#Teepseudo-muxer
 I am trying to do the example where the video stream is split and scaled
 to two different sized outputs, and the audio is encoded only once but
 used by both outputs.


 {{{
 ffmpeg -i input -filter_complex \
 "[0:v]split=2[s0][s1]; \
  [s0]scale=1280:-2[v0]; \
  [s1]scale=640:-2[v1]" \
 -map "[v0]" -map "[v1]" -map 0:a -c:v libx264 -c:a aac -f tee \
 "[select=\'v:0,a\']local0.mkv| \
  [select=\'v:0,a\':f=flv]rtmp://server0/app/instance/playpath| \
  [select=\'v:1,a\']local1.mkv| \
  [select=\'v:1,a\':f=flv]rtmp://server1/app/instance/playpath"
 }}}


 The issue is related with the ''select''.

 Reading this: https://www.ffmpeg.org/ffmpeg-formats.html#tee-1


 {{{
 select
 Select the streams that should be mapped to the slave output, specified by
 a stream specifier. If not specified, this defaults to all the input
 streams. You may use multiple stream specifiers separated by commas (,)
 e.g.: a:0,v
 }}}


 It is supposed that ''You may use multiple stream specifiers separated by
 commas (,)'' but it does not working (is ignoring streams specified after
 comma)

 So using this unofficial repo:

 sudo add-apt-repository ppa:jonathonf/ffmpeg-3


 I have updated ffmpeg to this version:

 Now ''select'' works well but I would prefer to use the official version
 for Ubuntu 16.04.

 Did you know about this issue?
 Are you planning to fix for Ubuntu 16.04?
 Are there other approaches to achieve the goal of the example?

 Thanks!
