Intel release an alpha version of Media SDK for linux servers (Intel® Media SDK 2013 for Linux Servers) recently, here now I am researching on it. I will record my research details in this post, as usual, can not guarantee everything I write here are exact true and right, only an experiment of it.
Intel® Media SDK 2013 for Linux Servers is an SDK for optimizing datacenter and embedded media applications for Linux operating systems to utilize Intel HD Graphics hardware acceleration capabilities. Now, quickly and easily develop optimized media applications for Linux operating systems such as encode, decode, and transcode for real-time streaming, teleconferencing, and video analytics.
You can visit: http://software.intel.com/en-us/vcsource/tools/media-sdk-linux to get more informations from Intel’s official website of Media SDK
- For Intel Xeon® E3-1285Lv2 and Intel Core™ Processor-based Platforms with Intel HD Graphics
- Encode, decode, and transcode for server-based streaming
- Supports Ubuntu* and SUSE* Linux Enterprise Operating Systems
- Supports H.264, MPEG-2, VC-1 formats
Step by step to setup the develop environment, and get into works. My hardware environemts(CPU) is Core 3rd Generation Ivy, according to Intel’s introduction in it Release Notes, I can only choose ubuntu 12.04 server 64 with kernel 3.2.
1. OS Install
According to Intel’s Release Notes, target OS version match with MediaSDK is ubuntu 12.04 server 64 bit with kernel 3.2.
So we choose: ubuntu-12.04-server-amd64.iso(we can not download this version of ubuntu server on ubuntu.com, if you dont have it, you can mail me or call me)
1. Get yourself a USB flash(4G or bigger), use unetbootin-windows-581.exe to write the iso to the USB flash.
2. Plug the USB to 8000e, and power up, press DEL to get into BIOS, choose your newly plugged in USB as first boot option.
3. Install Ubuntu server.
4. Make sure your 8000e can access to the internet (Mail your 8000e’s ethernet MAC ADDR together with your pre-assigned IP addr to 黄阳)
5. I strongly recommend you to not do it on 8000e’s iCF4000 card(which has only 8 GB rom), because I was sucked here 2 times being told “no space left” while compiling the kernel.
2. Media SDK install
1. haswell.rar which including but not limits to files:
Upload haswell.rar to 8000e, and extract it, you will find a file named as intel-linux-media_ubuntu_22.214.171.12478_64bit.tar.gz
1. Extract intel-linux-media_ubuntu_126.96.36.19978_64bit.tar.gz
2. Locate to the extracted files, find and execute ./install_media.sh

As you can see, I was told to rebuild the kernel, so we do it. However it’s a long way to go…
3. Install a bunch of stuffs with rebuild kernel needed:
If you encounter with network setting & routing problems, you can refer to http://bbs.rosoo.net/forum.php?m … pid=24641&fromuid=3 for a guide.
sudo apt-get install git g++ make curl sudo apt-get install ncurses-dev kernel-package
4. Download kernel
git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git cd linux-stable git checkout v3.2
5. Apply Intel Media SDK patch
jacky@ubuntu-msdk:~/kernel/linux-stable/include$ cd ../drivers/char/agp/ jacky@ubuntu-msdk:~/kernel/linux-stable/drivers/char/agp$ cp -r ~/msdk/kmd/source/xcode-ubuntu-kmd-rel/drivers/char/agp/* . jacky@ubuntu-msdk:~/kernel/linux-stable/drivers/char/agp$ cd ../../gpu/ jacky@ubuntu-msdk:~/kernel/linux-stable/drivers/gpu$ cp -r ~/msdk/kmd/source/xcode-ubuntu-kmd-rel/drivers/gpu/* . jacky@ubuntu-msdk:~/kernel/linux-stable/drivers/gpu$
6. Recompile kernel
make menuconfig make-kpkg --initrd --append-to-version -01 kernel_image kernel_headers -j8
