pyglet-1.1.4 memory leak in media.load streaming=True

[GoogleCodeExporter]

This code:

import pyglet

while True:
    source = pyglet.media.load("somefile.avi", streaming=True)

will give a memory leak soon with traceback:

Traceback (most recent call last):
  File "memleak.py", line 4, in <module>
    source = pyglet.media.load("test\AAA_Wielkanoc.avi", streaming=True)
  File "c:\python27\lib\site-packages\pyglet\media\__init__.py", line 1406, in load
    source = get_source_loader().load(filename, file)
  File "c:\python27\lib\site-packages\pyglet\media\__init__.py", line 1382, in load
    return avbin.AVbinSource(filename, file)

without "streaming = True" this code still gives a memory leak on pyglet 1.1.4

... and with the latest source checkout from google code's hg as for today 
(29.05.2014) the leak also exists.

as muppy does NOT show raised objects count, I believe this leak has something 
to do with libavbin, investigating...

With libavbin-5 the leak does NOT occur. 

The leak occurs with libavbin-10.

I was testing on win32 8 pro 64-bit, python 2.7 32bit.

libavbin-11 alpha4 for windows does NOT have the leak.

Thanks for the follow up. Nathan is working on a new release of AVBin so 11 
will be the stable version soon.
