GSPipeline no sound

[Offlink]

Hi

Thank you for this excellent library :D

We want make a client live streaming, the source no matters, mp4, flv, avi etc

We use a pipeline of GStreamer for this, but we have a mistake with the audio, in test "audiotestsrc"

Saving a file mp3 when this test, is ok

pipe = new GSPipeline(this, "audiotestsrc ! audioconvert ! lame ! filesink location=file.mp3 ");

But no sound live, taken the example of "Test.pde" use the following pipeline for audio:

pipe = new GSPipeline(this, "audiotestsrc ! audioconvert ! audio/x-raw-int,rate=8000,channels=1");

But get the following error

JNA: Callback org.gstreamer.Element$4@1b09282 threw the following exception:
org.gstreamer.Structure$InvalidFieldException: Structure does not contain integer field 'height'

The pipeline is wrong?  :(  or exist another way to sound the audio

Sorry my English

Thanks

Thanks for pointing this out!

I'm adding a new parameter for GSPipeline, which allows you to indicate that the pipeline is audio-only. Something like this:

pipe = new GSPipeline(this, "audiotestsrc ! audioconvert ! alsasink", GSVideo.AUDIO);

I'll upload the version of gsvideo with this new feature soon.

ok, try this one:

http://sourceforge.net/projects/gsvideo/files/gsvideo/test/gsvideo-20100627.zip/download

Let me know how it goes.

Forgot to mention, I put the sample pipeline in Examples/Pipelines/Test. Only the Linux version, for windows would be:

pipe = new GSPipeline(this, "audiotestsrc ! audioconvert ! directsoundsink", GSVideo.AUDIO);

Works !!  that's great

Excelent thank you

Tested in Windows and Ubuntu
