Hi,
   I installed ffmpeg as per instructions on:
https://trac.ffmpeg.org/wiki/CentosCompilationGuide

This is my ./configure:
./configure --prefix="$HOME/ffmpeg_build"
--extra-cflags="-I$HOME/ffmpeg_build/include"
--extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin"
--extra-libs="-ldl" --enable-gpl --enable-nonfree --enable-libfdk_aac
--enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx
--enable-libx264 --enable-x11grab

However, when i run ffmpeg,
$ffmpeg -f x11grab -r 25 -s 1280x720 -i :2.0 -vcodec libvpx out.webm
I encountered with an error of "Unknown encoder 'libvpx' "
Anyone happens to know what went wrong ?

Thank you
Pang Jun Jie
