Build

related git repos

1. git clone git://anongit.freedesktop.org/vaapi/libva
2. git clone git://anongit.freedesktop.org/vaapi/intel-driver
3. git clone -b release https://github.com/01org/libyami.git

environments:

• there is no special dependency to build libyami core library.
• if you want to build yami decode tests with texture-video support, additional EGL/GLES2 packages are required. (sudo apt-get install libgles2-mesa-dev libegl1-mesa-dev)
• yamidecode uses ffmpeg's avformat to demux container formats such as .mp4, .webm. you need clone git://source.ffmpeg.org/ffmpeg.git and configure libyami with --enable-avformat to support those files.

example script for build environments

your system maybe have pre installed libva. Build and install new one maybe make your system unstable. Following script will make sure you install library to /opt/yami. Please save them to env.sh. And "source env.sh" before you do any build things. many people use sudo to configure and install. it cause problem since sudo do not export the env.sh for root. please do not use sudo, just change install directory to writable like this "sudo chmod a+w /opt/yami"

    export export YAMI_ROOT_DIR=$1
