Subject: Re: [ecasound] GSM input and output

For the first point, I have a llok at the sources of ecasound and I see that
the mp3 (and others) use an external command (mp123) in order to process the
audio file. It seans that if I want to play gsm files, I have 3 possibility:
- write a AUDIO_IO_DEVICE subclass for handling gsm
- write a AUDIO_IO_FORKED_STREAM subclass and use some gsm (de)encoder
- find and use an ladspa plugin which handle directly the gsm.

Is that right?
please help me to find a ladspa plugin for gsm ...

For the second point, I see that there was an option in ecasound (-y) which
is available to specify the starting point of the audio file.

But : if I put:
ecasound -i minute.wav -y:2 -o /dev/dsp

I got:
(eca-audio-objects) Set starting position for audio object "minute.wav": 2.00
seconds.

BUT, the audio file is started at the 11 second instead of the second one. I
don't understand the way to specifiy the parameter of the -y option.
