Ok, I've just give it a try.
Thank you FakeOutdoorsman for the link to the excellent how-to on how to compile ffmepg
as it allowed me to creat a 'real' ffmpeg environment.
There is one thing I want to point out which extremely lighten me the decision
$ ffmpeg 2>&1 | head -n1
ffmpeg version git-2013-08-25-626739e Copyright (c) 2000-2013 the FFmpeg developers
to either try to install 'ffmpeg' or not. At the end of the how-to there is
explained how to remove anything that was just installed. That enabled me to
choose easily and to just give it a try because it would empower me to just undo
what I did before. Therefore a big respect for the whole guide, their maintainers
and the explanation on how to undo what was just done.
The only downpart of the how-to is that my home folder now contains several folders
which normally belong in other folders like '/usr'. However, this is ok for me considering
the advanced capability I now have.
Because now I can grab and record two audio sources and map them into one output
file on the fly. which was my original concern.
Command goes here:
I think you can certainly adjust and add further arguments for refinment but for me its
ffmpeg -f alsa -ac 2 -i pulse -f alsa -ac 1 -i plughw:2,0 -filter_complex amix=inputs=2 out.wav
sufficient atm as it just works without any distortion or strange audible artifacts (see
So far, thanks for all the work done by the different maintainers and programmers and also
of course thank you FakeOutdoorsman as you gave me an important impulse in order to
continue and pursue my goal and continue the work I have done so far.
For all others also struggling of setting up audio and get it running to do some screencasting
or desktoprecording or whatever, keep on trying and have same patience to achieve the goal.
Sometimes it is really difficult but finally it should work! gl!
