Hi vineeth,<br>
I had to do some other work that's why I answer so late. I found out
what the right pipeline is for mixing several audio files. The
command<br>
gst-launch adder name=mix ! audioconvert ! lamemp3enc ! filesink
location=out.mp3 filesrc location=input1.wav ! wavparse !
audioconvert ! mix. filesrc location=input2.wav ! wavparse !
audioconvert ! mix.<br>
works fine for me.<br>
<br>
Thanks all for your help.<br>
<br>

Probably some element is missing. Enable the logs, with export

thanks for reply. I tried the pipeline you posted.
Unfortunately I run

decodebin ! adder name=mix ! alsasink ! filesrc
location=/home/user/audio_tmp/tmp_audio_1.aif ! decodebin
! mix.<br>

Setting pipeline to PAUSED ...<br>
Pipeline is PREROLLING ...<br>

all,<br>
I have got serveral audio streams of
different length and have to mix
them. This means, the audio streams
have to be played at the same time
they haven't to be played one after
another - no concatenation. Does
gstreamer provide a workaround to
mix these streams?<br>

all,<br>
I have got a Slackware 13.0 linux
distribution and try to install
gstreamer plugins. As a
prerequisite of the plugin
installation the
plugin base installation is
required. I can do configure and
make.
However, make install ends with
the error "cannot stat
`.libs/libgstpango.lai'".<br>
Could anybody give a hint would be
appreciated.<br>
