Broadcom Crystal HD
Crystal HD is the Broadcom's hardware SIP core that performs video decoding. Crystal HD has been available as single chip high-definition advanced media processors BCM70012 and BCM70015; these chips are found on mini PCIe cards for purchase.
The BCM970012 supports hardware decoding of H.264/MPEG-4 AVC, VC-1, WMV9 and MPEG-2 and the BCM970015 additionally supports DivX 3.11, 4.1, 5.X, 6.X and Xvid. VP8, Daala and HEVC are not supported.
Operating system support
The Crystal HD SIP core needs to be supported by the device driver, which provides one or more interfaces such as VDPAU, VAAPI or DXVA. One of these interfaces is then used by end-user software, for example VLC media player or GStreamer, to access the PureVideo hardware and make use of it.
Broadcom has published a device driver for Linux under the GNU General Public License (GPL) version 2. Broadcom also published application and library source code on a royalty-free basis under the GNU Lesser General Public License (LGPL), version 2.1
