FFmpeg:intel核显vaapi驱动安装

---

主要需要安装media-driver和它的依赖。
开源，在github上

intel-media-driver

github 上下下来后，切下版本分支， 然后cmake直接编。

libva

checking for DRM… no
configure: error: Package requirements(libdrm >= 2.4)were not met:

No package ‘libdrm’ found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables DRM_CFLAGS
and DRM_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

sudo apt-get install libpciaccess-dev

这两个库装好后，回来安装media-drive

CMake Error at media_driver/media_top_cmake.cmake:114 (add_subdirectory):
add_subdirectory given source
“/home/sola/server_source/vaapi-driv/media-driver/…/gmmlib/Source/GmmLib”

– Configuring incomplete, errors occurred!

git clone https://github.com/intel/gmmlib.git

clone 一份下来 编译安装

注意 sudo apt-get install libigdgmm-dev这样安装的话，最后编译media-drive的时候会出问题。

装完gmm就能编过了，一切完工。

vaninfo&libva 配置

可以使用vaninfo 查看libva 信息，

然后你可能会遇到这种错误:

libva info: Trying to open /usr/lib/dri/i965_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

你会发现没有 这个 /usr/lib/dri/i965_drv_video.so 库文件， 我尝试做了个软连接 然后就能正常工作了

但这不是正道呀，google了下发现了下面信息。

原来我们只需要配置下这个环境变量即可
export LIBVA_DRIVER_NAME=iHD

ffmpeg

最后尝试ffmpeg进行vaapi硬解。

打开 vaapi : ./configure --enable-hwaccel=h264_vaapi --enable-gpl --disable-x86asm --enable-shared

test : ffmpeg -v trace -vaapi_device /dev/dri/card0 -i 720p.mp4 -vf 'format=nv12,hwupload' -c:v h264_vaapi output.mp4
