 Summary of the bug:

 static build ffmpeg segmentation faults when using VA-API hardware
 encoding.


 How to reproduce:

 build ffmpeg statically as below on Ubuntu 16.04
 (to build static binary with vaapi support, I have to set "--extra-libs"
 value. Is this a know issue?)
 {{{
 apt update
 apt upgrade -y
 apt install -y \
  build-essential \
  git \
  libdrm-dev
  libva-dev
  nasm \
  pkg-config \
  yasm

 git pull https://git.ffmpeg.org/ffmpeg.git
 cd ffmpeg

 ./configure \
  --prefix=/usr/local \
  --enable-pic \
  --enable-gpl \
  --enable-version3 \
  --enable-nonfree \
  --enable-static \
  --disable-shared \
  --disable-ffplay \
  --disable-doc \
  --extra-cflags="--static" \
  --extra-libs="-static -lva -ldl -ldrm -lm" \
  --enable-debug

  make
 }}}

 then,
 {{{
 # ./ffmpeg_g -vaapi_device /dev/dri/renderD128 -hwaccel vaapi
 -hwaccel_output_format vaapi -i /tmp/original.ts -vf
