[ecasound] ecasound and ecasound-iam give different length output

Hi All,

I try to use ecasound in interactive mode, but give me different output
length than input.

Using ecasound cmd line:

# ecasound -i media/samples/41/41_1_3255.wav -o media/output/mixed1.mp3

then I check the output:
==================================================================
# ecalength media/output/mixed1.mp3

***********************************************************************
* Message from libecasoundc:
*
* 'ECASOUND' environment variable not set. Using the default value
* value 'ECASOUND=ecasound'.
***********************************************************************

media/output/mixed1.mp3: 4.049s (0m4s)
===============================================================

then I try use ecasound -c

======================================
# ecasound -c
