[gst-devel] GStreamer-CRITICAL **: gst_bin_add: assertion `GST_IS_ELEMENT (element)' failed

[Guilherme]

Tim, I found my problem.
I was using a invalid element in a pipeline.

The question that still pending is how can I get handle of a buffered data??

    For example a simple situation:

       source -> sink  

    I know that data flows from the source src-pad to a buffer than to 
the sink-pad of the sink element.

    1 - Am I able to specify size for that buffer? Cause I want to dump 
the data in this buffer when its full to another buffer, than I can 
realize a operation with that second buffer while the first receives 
more data and so on..!

    2 - If the first option isn't a valid option, Is that possible to 
get handle of data in this first buffer even with the pipeline play. 
Cause I need to check the input that to perform a transformation with 
the data. FFT (fast fourier transform) to be more exactly. Since there 
is no plug-in available to perform that operation I have to do it 
separately.

    Great Regards;

Tks!
