ubuntu下集成intel qsv加速ffmpeg转码

软硬件环境

• ubuntu 16.04 64bit
• ffmpeg binary 3.3.4
• intel mss 2017-r3
• Intel(R) Core(TM) i5-5200U CPU @ 2.20GHz

准备工作

安装MSS

intel 安装包下载地址

https://software.intel.com/en-us/blogs/2017/07/11/whats-new-in-intel-media-server-studio-2017-r3，下载community的版本，这个是免费的

tar xvf MediaServerStudioEssentials2017R3.tar.gzcd MediaServerStudioEssentials2017R3tar xvf SDK2017Production16.5.2.tar.gzcd SDK2017Production16.5.2cd Generic(我这里是ubuntu系统，如果是centos就进入CentOS目录)# 安装libvacd opt/intel/mediasdk/opensource/libva/1.67.0.pre1-64009tar xvf libva-1.67.0.pre1.tar.bz2cd libva-1.67.0.pre1./configuremake sudo make install# 安装libdrmcd ../../../../../../../cd opt/intel/mediasdk/opensource/libdrm/2.4.67-64009tar xvf libdrm-2.4.67.tar.bz2cd libdrm-2.4.67./configuremakesudo make installcd ../../../../../../tar xvf intel-linux-media_generic_16.5.2-64009_64bit.tar.gzsudo install_media.shsudo reboot

在~/.bashrc中添加环境变量设置语句

LD_LIBRARY_PATH=/usr/local/lib:/usr/lib64LIBVA_DRIVER_NAME=iHDLIBVA_DRIVERS_PATH=/opt/intel/mediasdk/lib64

系统重启后，检查上述安装是否成功

编译kernel

下载地址

https://www.kernel.org/pub/linux/kernel/v4.x/,下载4.4版本，这个版本号必须要和MSS里提供的kernel补丁版本对应

tar xvf linux-4.4.tar.gzcd linux-4.4cp -r MediaServerStudioEssentials2017R3/SDK2017Production16.5.2/Generic/opt/intel/mediasdk/opensource/patches/kmd/4.4/intel-kernel-patches .for i in intel-kernel-patches/*.patch; do patch -p1 < $i; donemake olddefconfigmakemake modules_install sudo make installsudo reboot

编译比较耗时，静静等待

编译安装ffmpeg

通过apt-get安装的ffmpeg本身不支持h264_qsv选项(windows版本支持)，因此必须自己去重新编译，首先安装必备的工具包

sudo apt-get install libvdpau-dev libvorbis-dev libass-dev libgnutls-dev frei0r-plugins-dev libopencore-amrwb-dev libopencore-amrnb-dev libopenjpeg-dev libopus-dev libsoxr-dev libvo-amrwbenc-dev libvpx-dev libwebp-dev libxvidcore-dev

在/opt/intel/mediasdk/include中创建文件夹mfx，并把include下的所有头文件拷贝到mfx文件夹中，然后

mkdir -p /opt/intel/mediasdk/lib64/pkgconfigtouch /opt/intel/mediasdk/lib64/pkgconfig/libmfx.pc

libmfx.pc文件内容如下

prefix=/opt/intel/mediasdkexec_prefix=${prefix}libdir=${prefix}/lib/lin_x64includedir=${prefix}/includeName: libmfxDescription: Intel Media Server Studio SDKVersion: 16.4.2Libs: -L${libdir} -lmfx -lva -lstdc++ -ldl -lva-drm -ldrmCflags: -I${includedir} -I/usr/include/libdrm

最后一步，删除/usr/lib64下的所有libdrm*和libva*，我在这里被坑了很久，多个drm和va会导致ffmpeg编译时报错，如下

ffmpeg 3.3.4源码包下载地址

https://www.ffmpeg.org/download.html#get-sources

tar xvf ffmpeg-3.3.4.tar.bz2cd ffmpeg-3.3.4./configure --enable-gpl --enable-version3 --enable-static --disable-debug --disable-indev=sndio --disable-outdev=sndio --enable-fontconfig --enable-frei0r --enable-gnutls --enable-gray --enable-libass --enable-libfreetype --enable-libfribidi --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxvidmakesudo make install

期间一般都会出现各种错误，通过查看config.log文件,依个解决．

测试

通过一下命令查看
