Description Tim-Philipp Müller 2013-01-29 00:07:19 UTC 
+++ 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.

This exposes some architectural deficiencies in qtdemux that I'd like to see fixed.  In particular, I have written a completely new ISO media file parser that is in GSS that would be a useful base.

This bug is on my to-do list (but low priority) at Rdio.
Comment 3 Edward Hervey 2018-05-04 11:06:17 UTC 
This should be fixed. If someone has a sample, re-check against current master and if it still is an issue re-open the bug.
