Using Intel QuickSync Encoders

In order to use QuickSync encoders, the following packages should be installed. This setup procedure is for ubuntu 18.04.

QuickSync is supported in Ant Media Server v2.4.0 and later versions.

Basic requirements​

sudo apt install cmake build-essential pkg-config autoconf libtool libdrm-dev libva-dev libx11-dev

Make sure to enable the graphics cards in BIOS (Chipset > North Bridge > Graphics Configuration):

Install GMMLIB​

git clone https://github.com/intel/gmmlib.git
cd gmmlib/
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release -DARCH=64 ..
make 
sudo make install
cd ../..

Install Libva​

git clone https://github.com/intel/libva.git
cd libva/
 ./autogen.sh
make 
sudo make install
cd ..

Install Intel media driver​

git clone https://github.com/intel/media-driver.git
mkdir build_media
cd build_media
cmake ../media-driver
make 
sudo make install
cd ..

Install Intel media SDK​

git clone https://github.com/Intel-Media-SDK/MediaSDK msdk
cd msdk
mkdir build && cd build
cmake ..
make
sudo make install
echo "/opt/intel/mediasdk/lib/" >` msdk.conf
sudo mv msdk.conf /etc/ld.so.conf.d/
sudo ldconfig

Install and configure Ant Media Server​

First, install Ant Media Server. Then, edit the properties file:

sudo nano /usr/local/antmedia/webapps/WebRTCAppEE/WEB-INF/red5-web.properties

 In this file, add settings.encoding.encoderName=h264_qsv save and exit from the editor.

Add antmedia user to video group

sudo usermod -aG video antmedia

Restart the Ant Media Server

sudo service antmedia restart

  • Go to the web panel and add adaptive bitrate.

  • Publish stream with RTMP or WebRTC.

  • Check the logs if h264_qsv is opened. You should see something like that:

    2021-06-27 07:17:06,209 [vert.x-worker-thread-2] INFO i.a.e.adaptive.video.H264Encoder - Video codec opened. Context gop size: 40 keyint mint 25 extradata size: 47 video codec timebase: 1/20 codecName: h264_qsv for stream: stream1
