Public bug reported:
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?
Thanks!
