[gst-devel] Need help on Audio 'cutter' element

Subject: Need help on Audio 'cutter' element

Hello all,

I heard about Audio 'cutter' element in the archives. I am hoping I can use
this element to resize the audio buffer flowing into my filter plugin's
_chain() function.


PROBLEM: 

I have developed a gstreamer filter (say "wow"). I have to process the in
coming audio data (GstBuffer)in the gst_wow_chain() and push it to the source
pad.

Here, my 'CONSTRAINT' is that the buffer size should be a MULTIPLE of
(exactly) 64 bytes, for processing. 

When a few wav files (with 3,4,5,6channels) are used for processing, the
buffer size breaks my 'CONSTRAINT' :-(.



QUESTION:

I want to know if audio cutter can help my filter by providing a buffer size
with 64 byte multiple. 

If so please let me know if there is user guide for cutter..! :-(

ALTERNATIVE DESIGN:

I have to do (unnecessary copy operation in _chain() to resize the buffer
size for processing. I want to avoid this.


This is very urgent. Please, help me out!

Thanks and regards,
Sharath
