Re: [ecasound] Re: Bug#284312: OGG recording with low bit-rates doesn't work

oggenc from vorbis-tools-1.0-3 handles this situation just fine. But it's 
also possible to avoid the problem by explicitly setting the bitrate on 
the command-line:

ecasound -i foo.wav  -o foo.ogg,64000 

This will run oggenc with:
oggenc -b 64 --raw --raw-bits=16 --raw-chan=2 --raw-rate=22050 --raw-endianness 0 --output=foo.ogg -

...

As a more general comment, I do admit that maintaining support for these
external tools is a difficult task and most of the (maintainable) ways to
work with them are more fragile than native support via libraries.  OTOH,
with libraries you have the extra burdon of maintaining autoconf/m4 macros
to adapt to all the different versions and ways to install theexternal
libraries, which is a not a simple task either. ;) 

Good ideas on how to improve the situation are very welcome. :)
