mixing text spoken streams and white noise

Hi all,
I want to mix text spoken streams with white noise stream. For all streams I
created wav files and try to mix the files. The pipeline is configured as
followed:

gst-launch.exe adder name=mix ! audioconvert ! lamemp3enc ! filesink
location="C:/tmp/result.mp3" filesrc location="C:/tmp/tmp_audio_2.wav" !
wavparse ! audioconvert ! mix. filesrc location="C:/tmp/whiteNoise-2db-5s.wav"
! wavparse ! audioconvert ! mix.

I get the error
/GstPipeline:pipeline0/GstWavParse:wavparse0:
streaming task paused, reason not-linked (-1)
ERROR: pipeline doesn't want to preroll.

If I mix to text spoken wav files - the white noice file replaced by a text
spoken wav the pipeline works fine.

Is there anybody could give a hint?

Best regards

Re: mixing text spoken streams and white noise

Can you please run the pipeline with -v after gst-launch, that will show the caps that are getting negotiated ?
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.

Also its a good habit to use queue before mix on each branch.

Best Luck

Hi Andrea,

In case it is useful I thought I should mention that you can also
generate white gaussian noise using audiotestsrc with the wave
property set to 9 rather than reading it from a wav file.

best,

Chad

Re: mixing text spoken streams and white noise

In reply to this post by Kapil Agrawal

Hi kapil,
many thanks for your reply. I run my pipeline with -v option and got the
following output:

/GstPipeline:pipeline0/GstAdder:mix.GstPad:sink1: caps = NULL
/GstPipeline:pipeline0/GstAdder:mix.GstPad:sink0: caps = NULL
/GstPipeline:pipeline0/GstAdder:mix.GstPad:src: caps = NULL
/GstPipeline:pipeline0/GstAudioConvert:audioconvert1.GstPad:src: caps = NULL
/GstPipeline:pipeline0/GstAudioConvert:audioconvert1.GstPad:sink: caps = NULL
/GstPipeline:pipeline0/GstWavParse:wavparse0.GstPad:src: caps = NULL
/GstPipeline:pipeline0/GstWavParse:wavparse1.GstPad:src: caps = NULL

Could you give a hint. Caps filter I set.

Right now it does

(5): white-noise - White uniform noise
(6): pink-noise - Pink noise
(9): gaussian-noise - White Gaussian noise

According to http://en.wikipedia.org/wiki/Colors_of_noise
red is a synonym to pink or brownian noise. Anyway, I filed
https://bugzilla.gnome.org/show_bug.cgi?id=649969
which would be an easy one for someone who would like to start
contributing to gstreamer (hint hint).

Re: mixing text spoken streams and white noise

Hi Stefan,
many thanks for your help. I added capsfilter between audioconvert and
mix but still got the same error. If I run gst-launch with -v option the
caps properties are displayed. It seems there are the same caps for the
elements.

gst-launch -v adder name=mix ! audioconvert ! lamemp3enc ! filesink
location=/test_noise.mp3 filesrc location="/whiteNoise-vol001.wav" !
wavparse ! audioconvert ! mix. filesrc location="/tmp_audio_0.wav" !
wavparse ! audioconvert ! mix.

FEHLER: Von Element /GstPipeline:pipeline0/GstWavParse:wavparse0:

Zusätzliche Fehlerdiagnoseinformation:

Can you tell me what goes wrong?

Thanks in advanced.

Re: mixing text spoken streams and white noise

Hi Stefan,
I found out why the pipeline didn't work. One of the sources hadn't the
right format. I set the right format to this source and it seems to work
fine.

Many thanks for your help.
