unbuntu12.04上安装intel linux media SDK

1. 简介

    官方地址：https://software.intel.com/en-us/vcsource/tools/media-sdk-server

    Intel® Media SDK 2014 for Servers is an SDK for optimizing datacenter and embedded media applications for Linux and Windows server operating systems to utilize Intel Iris™ Pro and Intel HD Graphics hardware acceleration capabilities. Now, quickly and easily develop optimized media applications for Linux and Windows server operating systems such as encode, decode, and transcode for real-time streaming, teleconferencing, and video analytics.

Features:

• For Intel Xeon® processor E3-1200 v3 product family and 4th Generation Intel Core™ Processor-based Platforms with Intel Iris™ Pro and Intel HD Graphics
• Encode, decode, and transcode for server-based streaming
• Supports Ubuntu*, SUSE* Linux Enterprise, Windows Server 2012* operating systems
• Supports H.264 (AVC), H.265 (HEVC), MPEG-2, VC-1 formats

2. 下载SDK

    intel这个SDK是需要购买的，要价499美元。不过呢，可以下载一个30天的试用版。

3. 安装SDK

3.1 安装环境

    intel media SDK对硬件、系统及软件均有限制，这点需要注意下，否则不能按照官方提供的方法安装。具体的环境要求为：

Hardware
The following processor models are supported:
    Intel® Xeon® Processor E3-1285 v3 and E3-1285L v3 (Intel C226 Chipset) with Intel HD Graphics P4700
    4th Generation Intel Core™ Processors with Intel Iris™ Pro Graphics, Intel Iris Graphics or Intel HD Graphics 4200+ Series
    3rd Generation Intel Core Processors with Intel HD Graphics 4000/2500
The following processor models are supported but not recommended for new designs:
    Intel Xeon Processor E3-1285 v2 and E3-1285L v2 (Intel C216 Chipset) with Intel HD Graphics P4000
Please note: Intel Xeon processors are only supported with the chipsets listed. Intel Xeon configurations with other chipsets are not supported. Previous generations of Intel Core processors are not supported. Intel Celeron® and Intel Atom™ processors are also not supported.
Software
    Ubuntu* 12.04 LTS for 64-bit architecture (currently 12.04.3) or SUSE* Linux* Enterprise Server 11 for 64-bit architecture
    Xf86-video-intel driver (needed only for local rendering with LibVA X11 backend support). Recommended version: 2.20.10, http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/snapshot/xf86-video-intel-2.20.10.tar.gz
    Additional platform-specific software requirements (X indicates a supported combination – only these hardware/kernel combinations are supported):

    具体可以参考SDK中提供的文档。

3.2 当前环境

    硬件为英特尔Core i7-3770S，HD Graphics 4000，符合要求。

    然后装了ubuntu 12.04， 内核版本Linux 3.11.0-15-generic

3.3 更新内核
    对于当前系统，文档要求系统内核版本为Linux 3.2.0-41-generic。

sudo apt-get install linux-image-3.2.0-41-generic linux-headers-3.2.0-41-generic

3.4 安装

重启系统后选择3.2.0-41内核版本。

很顺利的安装成功了。

注：

最好是安装ubuntu12.04.01，然后给kernel升级到指定版本就行了。

系统需要apt-get upgrade
