+++ This bug was initially created as a clone of Bug #663458 +++

An Olympus LS-20M Linear PCM camera recorder created this mov file that has a
lpcm FOURCC in there and it isn't supported by gstreamer.

Afraid to attach a video clip here as the HD video is large, so I will host a
short clip here for a while:
http://lightcloud.verns.net/foo.mov

===========================

In git master we can now extract the PCM audio, but we need to find a way to
output multiple audio frames per buffer, the audiosink just can't deal with
48000 buffers per second.
