Leif Johnson 44d4269dc8 Modified passthrough, adder, playondemand, float2int, int2float, and ladspa to work with the new caps nego changes. 
Original commit message from CVS:
Modified passthrough, adder, playondemand, float2int, int2float, and ladspa to
work with the new caps nego changes.

Updated adder to work with float data, now uses bytestreams.

Updated ladspa to work in any M sinkpads by N srcpads configuration, M > -1 and
N > 0. Also updated ladspa to work as a loop-based element using bytestreams for
MxN configurations other than M == N == 1 or M == 0.

README 

This plugin wraps the SGI Audiofile 
(http://oss.sgi.com/projects/audiofile/) library into a src and sink
element.

You can read from and write to the supported formats (WAVE, AIFF, AIFFC,
NEXTSND).

What is supported :
* all the file formats
* integer sample data, both 2's complement and unsigned
* 8 or 16 bit width & depth (haven't tested others)
* sample rate
* some sort of endianness control

What isn't supported yet :
* float data

What you can do :
* src element only accepts location argument
* sink element accepts location, endianness and type
	- location : file on the system to output
	- endianness : at this time endianness is still a bit shady
	  	you can either set 1234 or 4321;
		setting it to 4321 will byteswap the buffer data
		you might want to keep it at 1234 for now
	- type : one of the file types

Use gstreamer-inspect on afsink and afsrc to see all of the supported
options.

Examples :

* tools/gstreamer-launch afsrc location=/opt/media/wav/dark-480-16-m.wav ! afsink type=2 location=/opt/media/wav/dark-480-16-m.aiff

Future plans :

* add float support
* wrap up afsink and afsrc with pipe and fork to act like data convertors,
  allowing arbitrary choice of sink and src element
