Description
Hi,
I am using the last version available for Ubuntu 16.04
ffmpeg version 2.8.11-0ubuntu0.16.04.1 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.4) 20160609 configuration: --prefix=/usr --extra-version=0ubuntu0.16.04.1 --build-suffix=-ffmpeg --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --cc=cc --cxx=g++ --enable-gpl --enable-shared --disable-stripping --disable-decoder=libopenjpeg --disable-decoder=libschroedinger --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-librtmp --enable-libschroedinger --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzvbi --enable-openal --enable-opengl --enable-x11grab --enable-libdc1394 --enable-libiec61883 --enable-libzmq --enable-frei0r --enable-libx264 --enable-libopencv libavutil 54. 31.100 / 54. 31.100 libavcodec 56. 60.100 / 56. 60.100 libavformat 56. 40.101 / 56. 40.101 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 40.101 / 5. 40.101 libavresample 2. 1. 0 / 2. 1. 0 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 2.101 / 1. 2.101 libpostproc 53. 3.100 / 53. 3.100
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:
ffmpeg version 3.3-1~16.04.york1 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.4) 20160609 configuration: --prefix=/usr --extra-version='1~16.04.york1' --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --enable-gpl --disable-stripping --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmp3lame --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-omx --enable-openal --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libopencv --enable-libx264 --enable-shared libavutil 55. 58.100 / 55. 58.100 libavcodec 57. 89.100 / 57. 89.100 libavformat 57. 71.100 / 57. 71.100 libavdevice 57. 6.100 / 57. 6.100 libavfilter 6. 82.100 / 6. 82.100 libavresample 3. 5. 0 / 3. 5. 0 libswscale 4. 6.100 / 4. 6.100 libswresample 2. 7.100 / 2. 7.100 libpostproc 54. 5.100 / 54. 5.100
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!

You cannot use current documentation to report a bug in an old version.
It is not the decision of the FFmpeg developers if Ubuntu will update their FFmpeg version (for old Ubuntu) - for all I know, they won't though.
