i guess there are much more informations needes

* OS + version
* ffmpeg-version
* version of libvpx
* configure-flags of your ffmpeg


because on all of my machnes with self-compiled ffmpeg/libvpx
snaphsots of webm-files and convert rom all formats to webm
and from webm to all formats works like a charme
