Can you please run the pipeline with -v after gst-launch, that will show the caps that are getting negotiated ?<br>Also I suspect there is a mismatch between the formats of two wav files, hence not-linked error, you might want to add appropriate capsfillter audioconvert of both wavfiles.<br>
<br>Also its a good habit to use queue before mix on each branch.<br><br>Best Luck<br>kapil<br><br><div class="gmail_quote">2011/5/11 Andrea König <span dir="ltr"><<a href="mailto:andrea.koenig@gmatic.de">andrea.koenig@gmatic.de</a>></span><br>

I want to mix text spoken streams with white noise stream. For all streams I<br>
created wav files and try to mix the files. The pipeline is configured as<br>
followed:<br>
<br>
gst-launch.exe adder name=mix ! audioconvert ! lamemp3enc ! filesink<br>
location="C:/tmp/result.mp3" filesrc location="C:/tmp/tmp_audio_2.wav" !<br>
wavparse ! audioconvert ! mix. filesrc location="C:/tmp/whiteNoise-2db-5s.wav"<br>
! wavparse ! audioconvert ! mix.<br>
<br>
I get the error<br>
/GstPipeline:pipeline0/GstWavParse:wavparse0:<br>
streaming task paused, reason not-linked (-1)<br>
ERROR: pipeline doesn't want to preroll.<br>
<br>
If I mix to text spoken wav files - the white noice file replaced by a text<br>
spoken wav the pipeline works fine.<br>
<br>
Is there anybody could give a hint?<br>
<br>
Best regards<br>
