Hello
I use intensively ecasound to do linear fading and so on, i've no problem at all, except on one specific example, maybe it's a bug, i dunno:
here is a simple .ewf file, named bug.ewf (2 lines)
source = 10.wav
looping = true
You'll find in attachment the file 10.wav, and i launch the command:
/usr/bin/ecasound -i:bug.ewf -ea:100 -klg:1,0,100,1,0,1 -t 10.877 -a:all -f:s16_le,1,11025 -o bug.wav
All is ok, here is the output:

HOWEVER, when i check bug.wav, with for example ffmpeg -i bug.wav, i get an error:

[flic @ 0xb7ef57d4]Could not find codec parameters (Video: flic, 16727x17750)
bug.wav: could not find codec parameters
ffmpeg thinks this wav is a video flic file?? completely a non sense, so maybe the .wav created is corrupted ? (i've tried on different install of ecasound and ffmpeg, and same problem)
Thanks for your help!
and god bless ecasound...
Enzo
