If you have a Broadcom Crystal HD device such as the newer model:
Multimedia controller: Broadcom Corporation BCM70015 Video
Decoder Crystal HD
Then this version still lack upstream linux kernel support (even in staging). There is a need to compile an external tree that start to diverge with the few fixes that are made in the staging version. Unfortunately I don't see any improvement with the support of this device. Exept that Android for x86 and it's 3.10 kernel seems to properly handle it (probably using distro patches).
So here is a package that can be installed on Fedora 20 for i686 and x86_64.
yum install akmod-crystalhd
I'm using the vlc-extras sub-package for the vlc crystalhd plug-in in order not to add a dependency that can be used in rare cases.
vlc --codec crystalhd multimedia.mp4
