Hi,

aMSN uses gstreamer/farsight for audio/video calls and it looks like gstreamer contains an assert that shouldn't be there... 

In the following program, I dynamically link elements when the pipeline is running and my 'volume' element gets as input caps "audio/x-raw-int,width=8,depth=8,rate=44100,signed=true,channels=1" but in it's output caps it has 'endianness=1234' added.. this is caused by osssrc that has the endianness missing for the 'width=8,depth=8,...' caps.

In gst_audio_filter_set_caps, there's an assert on gst_caps_equal(incaps, outcaps).

First, osssrc should add the endianness for its width/depth=8 caps, but also the assert in gstaudiofilter.c should either be removed or should be on gst_caps_interest, not on gst_caps_equal...
Here's the small python code that reproduces the error (same as my C app), as well as the assertion error I get and the backtrace.

-------------- example code -------------------
#!/usr/bin/python
import gst, time

p = gst.parse_launch("osssrc ! audio/x-raw-int, width=8 ! valve name=v drop=true")
p.set_state(gst.STATE_PLAYING)

time.sleep(1)

v = p.get_by_name("v")
b = gst.parse_bin_from_description("volume ! fakesink", True)
p.add(b)
v.link(b)
p.set_state(gst.STATE_PLAYING)

v.set_property("drop", False)

time.sleep(1)
-----------------------------------------------
---------------------- output -----------------
**
ERROR:gstaudiofilter.c:168:gst_audio_filter_set_caps: assertion failed: (gst_caps_is_equal (incaps, outcaps))
zsh: abort      python bug_gstreamer.py

Please fix before the next release.
