To enhance if other requirements:
  --enable-frei0r   ==> Could benefit from adding cross/cairo
                        Generates the following extras libs:
                           lib:lib/frei0r-1/cairoaffineblend.so
                           lib:lib/frei0r-1/cairoblend.so
                           lib:lib/frei0r-1/cairogradient.so
                           lib:lib/frei0r-1/cairoimagegrid.so

Potential candidates for enablement:
  --enable-ladspa
  --enable-libbs2b 
  --enable-libcdio 
  --enable-libflite 
  --enable-libgme 
  --enable-libgsm 
  --enable-libssh

  --enable-librubberband 
  --enable-libsrt 
  --enable-libvidstab 
  --enable-lv2 
  --enable-pocketsphinx

  --enable-libjack 
  --enable-libpulse 
  --enable-libxvid 
  --enable-omx 
  --enable-openal 
  --enable-opengl
