Compiling FFmpeg with VAAPI enabled results in failure at: /FFmpeg/libavutil/hwcontext_vaapi.c:1235: undefined reference to `vaSetErrorCallback' using libva master branch

[Dennis E. Mungai]

Summary of the bug:

Building FFmpeg with VAAPI enabled results in the error above. Attaching relevant logs below.

Notes: I installed libva from upstream, compiled from source: ​https://github.com/intel/libva/tree/master

How to reproduce:

Build libva and libva-utils from upstream, confirm all is working as expected via vainfo, then build FFmpeg:

1. vainfo:

vainfo
libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/local/lib/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_1_1

      VAProfileH264High               :    VAEntrypointVLD
      VAProfileH264High               :    VAEntrypointEncSlice
      VAProfileH264StereoHigh         :    VAEntrypointVLD
      VAProfileVC1Simple              :    VAEntrypointVLD
      VAProfileVC1Main                :    VAEntrypointVLD
      VAProfileVC1Advanced            :    VAEntrypointVLD

      VAProfileJPEGBaseline           :    VAEntrypointVLD

How libva and its' components were built:

Build platform: Ubuntu 16.04LTS

Installing the base dependencies:

sudo apt-get -y install autoconf automake build-essential libass-dev libtool pkg-config texinfo zlib1g-dev libva-dev cmake mercurial libdrm-dev

I then created a clean working directory and worked from there:

mkdir -p ~/vaapi
mkdir -p ~/ffmpeg_build

Individual components:

1. cmrt:

This is the C for Media Runtime GPU Kernel Manager for Intel G45 & HD Graphics family. it's a prerequisite for building the intel-hybrid-driver package.

cd ~/vaapi
git clone https://github.com/01org/cmrt
cd cmrt
./autogen.sh
./configure
time make -j$(nproc) VERBOSE=1
sudo make -j$(nproc) install

2. libva:

Libva is an implementation for VA-API (Video Acceleration API)

VA-API is an open-source library and API specification, which provides access to graphics hardware acceleration capabilities for video processing. It consists of a main library and driver-specific acceleration backends for each supported hardware vendor. It is a prerequisite for building the VAAPI driver components below.

cd ~/vaapi
git clone https://github.com/01org/libva
cd libva
./autogen.sh
./configure
time make -j$(nproc) VERBOSE=1
sudo make -j$(nproc) install

3. intel-hybrid-driver:

This package provides support for WebM project VPx codecs. GPU acceleration is provided via media kernels executed on Intel GEN GPUs. The hybrid driver provides the CPU bound entropy (e.g., CPBAC) decoding and manages the GEN GPU media kernel parameters and buffers.

This package grants access to the VPX-series hybrid decode capabilities on supported hardware configurations.

cd ~/vaapi
git clone https://github.com/01org/intel-hybrid-driver
cd intel-hybrid-driver
./autogen.sh
./configure
time make -j$(nproc) VERBOSE=1
sudo make -j$(nproc) install

4. intel-vaapi-driver:

This package provides the VA-API (Video Acceleration API) user mode driver for Intel GEN Graphics family SKUs. The current video driver back-end provides a bridge to the GEN GPUs through the packaging of buffers and commands to be sent to the i915 driver for exercising both hardware and shader functionality for video decode, encode, and processing. it also provides a wrapper to the intel-hybrid-driver when called up to handle VP8/9 hybrid decode tasks on supported hardware (when configured with the --enable-hybrid-codec option as shown below:).

cd ~/vaapi
git clone https://github.com/01org/intel-vaapi-driver
cd intel-vaapi-driver
./autogen.sh
./configure --enable-hybrid-codec
time make -j$(nproc) VERBOSE=1
sudo make -j$(nproc) install

5. libva-utils:

This package provides a collection of tests for VA-API, such as vainfo, needed to validate a platform's supported features (encode, decode & postproc attributes on a per-codec basis by VAAPI entry points information).

cd ~/vaapi
git clone https://github.com/intel/libva-utils
cd libva-utils
./autogen.sh
./configure
time make -j$(nproc) VERBOSE=1
sudo make -j$(nproc) install

I then set the environment variables for the VAAPI drivers as shown below:

Check if LIBVA environment variables are correctly configured:

set | grep LIBVA

Should output something like:

LIBVA_DRIVER_NAME=i965
LIBVA_DRIVERS_PATH=/usr/local/lib/dri

If not (as expected), set them on your system environment variables (/etc/environment) and reboot.

sudo systemctl reboot

After the reboot, I then proceeded to build FFmpeg as shown:

Preparing the workspace directories:

mkdir -p $HOME/bin
chown -Rc $USER:$USER $HOME/bin
mkdir -p ~/ffmpeg_sources

Including extra components as needed:

(a). Build and deploy nasm: Nasm is an assembler for x86 optimizations used by x264 and FFmpeg. Highly recommended or your resulting build may be very slow.

Note that we've now switched away from Yasm to nasm, as this is the current assembler that x265,x264, among others, are adopting.

cd ~/ffmpeg_sources
wget wget http://www.nasm.us/pub/nasm/releasebuilds/2.14rc0/nasm-2.14rc0.tar.gz
tar xzvf nasm-2.14rc0.tar.gz
cd nasm-2.14rc0
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" 
make -j$(nproc) VERBOSE=1
make -j$(nproc) install
make -j$(nproc) distclean

(b). Build and deploy libx264 statically: This library provides a H.264 video encoder. See the H.264 Encoding Guide for more information and usage examples. This requires ffmpeg to be configured with --enable-gpl --enable-libx264.

cd ~/ffmpeg_sources
git clone http://git.videolan.org/git/x264.git -b stable
cd x264/
PATH="$HOME/bin:$PATH" ./configure --prefix="$HOME/ffmpeg_build" --enable-static --disable-opencl
PATH="$HOME/bin:$PATH" make -j$(nproc) VERBOSE=1
make -j$(nproc) install VERBOSE=1
make -j$(nproc) distclean

(c). Build and configure libx265: This library provides a H.265/HEVC video encoder. See the H.265 Encoding Guide for more information and usage examples.

cd ~/ffmpeg_sources
hg clone https://bitbucket.org/multicoreware/x265
cd ~/ffmpeg_sources/x265/build/linux
PATH="$HOME/bin:$PATH" cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$HOME/ffmpeg_build" -DENABLE_SHARED:bool=off ../../source
make -j$(nproc) VERBOSE=1
make -j$(nproc) install VERBOSE=1
make -j$(nproc) clean VERBOSE=1

(d). Build and deploy the libfdk-aac library: This provides an AAC audio encoder. See the AAC Audio Encoding Guide for more information and usage examples. This requires ffmpeg to be configured with --enable-libfdk-aac (and --enable-nonfree if you also included --enable-gpl).

cd ~/ffmpeg_sources
wget -O fdk-aac.tar.gz https://github.com/mstorsjo/fdk-aac/tarball/master
tar xzvf fdk-aac.tar.gz
cd mstorsjo-fdk-aac*
autoreconf -fiv
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make -j$(nproc)
make -j$(nproc) install
make -j$(nproc) distclean

(e). Build and configure libvpx

   cd ~/ffmpeg_sources
   git clone https://chromium.googlesource.com/webm/libvpx
   cd libvpx
   ./configure --prefix="$HOME/ffmpeg_build" --enable-runtime-cpu-detect --enable-vp9 --enable-vp8 \
   --enable-postproc --enable-vp9-postproc --enable-multi-res-encoding --enable-webm-io --enable-better-hw-compatibility --enable-vp9-highbitdepth --enable-onthefly-bitpacking --enable-realtime-only --cpu=native --as=nasm 
   time make -j$(nproc)
   time make -j$(nproc) install
   time make clean -j$(nproc)
   time make distclean

(f). Build LibVorbis

   cd ~/ffmpeg_sources
   wget -c -v http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.6.tar.xz
   tar -xvf libvorbis-1.3.6.tar.xz
   cd libvorbis-1.3.6
   ./configure --enable-static --prefix="$HOME/ffmpeg_build"
   time make -j$(nproc)
   time make -j$(nproc) install
   time make clean -j$(nproc)
   time make distclean

(g). Build FFmpeg:

cd ~/ffmpeg_sources
git clone https://github.com/FFmpeg/FFmpeg -b master
cd FFmpeg
PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig:/usr/local/lib/pkgconfig" ./configure \
  --pkg-config-flags="--static" \
  --prefix="$HOME/bin" \
  --extra-cflags="-I$HOME/bin/include" \
  --extra-ldflags="-L$HOME/bin/lib" \
  --bindir="$HOME/bin" \
  --enable-vaapi \
  --disable-debug \
  --enable-libvorbis \
  --enable-libvpx \
  --enable-libdrm \
  --enable-gpl \
  --cpu=native \
  --enable-opengl \
  --enable-libfdk-aac \
  --enable-libx264 \
  --enable-libx265 \
  --extra-libs=-lpthread \
  --enable-nonfree 
PATH="$HOME/bin" make -j$(nproc) 
make -j$(nproc) install 
make -j$(nproc) distclean 
hash -r

[jkqxz]

You have a pre-libva2 version of libva before the one you actually want to use in the library path. You need to link with the same version as you have headers for.

[Dennis E. Mungai]

Thanks, adding the options below fixed the build:

--extra-cflags="-I/usr/local/include" \
--extra-ldflags="-L/usr/local/lib" \

Marking as solved.
