Build

Build step

Get the source code

* git clone git://anongit.freedesktop.org/vaapi/libva
* git clone git://anongit.freedesktop.org/vaapi/intel-driver
* git clone -b apache https://github.com/01org/libyami.git
* git clone https://github.com/01org/ffmpeg_libyami.git

Create the install directory

$ sudo mkdir -p /opt/ffmpeg && sudo chmod a+w /opt/ffmpeg
$ sudo mkdir -p /opt/yami && sudo chmod a+w /opt/yami

Soure the env.txt

env.txt setting the build env as follow

#!/bin/sh

if [ -n "$1" ]; then
    export export YAMI_ROOT_DIR=$1
else
    export YAMI_ROOT_DIR="/opt/yami"
fi

export FFMPEG_PREFIX="/opt/ffmpeg"
export VAAPI_PREFIX="${YAMI_ROOT_DIR}/vaapi"
export LIBYAMI_PREFIX="${YAMI_ROOT_DIR}/libyami"

ADD_PKG_CONFIG_PATH="${VAAPI_PREFIX}/lib/pkgconfig/:${LIBYAMI_PREFIX}/lib/pkgconfig/:${FFMPEG_PREFIX}/lib/pkgconfig/"
ADD_LD_LIBRARY_PATH="${VAAPI_PREFIX}/lib/:${LIBYAMI_PREFIX}/lib/:${FFMPEG_PREFIX}/lib/"
ADD_PATH="${VAAPI_PREFIX}/bin/:${LIBYAMI_PREFIX}/bin/:${FFMPEG_PREFIX}/bin/"

PLATFORM_ARCH_64=`uname -a | grep x86_64`
if [ -n "$PKG_CONFIG_PATH" ]; then
    export PKG_CONFIG_PATH="${ADD_PKG_CONFIG_PATH}:$PKG_CONFIG_PATH"
elif [ -n "$PLATFORM_ARCH_64" ]; then
    export PKG_CONFIG_PATH="${ADD_PKG_CONFIG_PATH}:/usr/lib/pkgconfig/:/usr/lib/i386-linux-gnu/pkgconfig/"
else
    export PKG_CONFIG_PATH="${ADD_PKG_CONFIG_PATH}:/usr/lib/pkgconfig/:/usr/lib/x86_64-linux-gnu/pkgconfig/"
fi

export LD_LIBRARY_PATH="${ADD_LD_LIBRARY_PATH}:$LD_LIBRARY_PATH"

export PATH="${ADD_PATH}:$PATH"

Follow the env.sh, build the source code

And the link https://github.com/01org/libyami/wiki/Build is the good reference for the build, but you need to use the new configure option for ffmpeg_yami build.

Check the build

After build finished, you can check the ffmpeg libyami h.264 transcode with the command:

$ ./ffmpeg -y -c:v libyami_h264 -i skyfall2-trailer.mp4 -vf "yamivpp=w=720:h=480:pipeline=1" -an -c:v libyami_h264 testvpp.ts

FATE

After build finished, you can used FATE(FFmpeg Automated Testing Environment) run regression test suite like this:

$ make fate-libyami-h264 SAMPLES=fate-suite/

For FATE, more information you can refer to the link https://www.ffmpeg.org/fate.html
