Introduction to libvpx

This package is known to build and work properly using an LFS-7.8 platform.

Now, as the root user: 

make install

Command Explanations

sed ... && chmod ...: These commands correct ownership and permissions of installed files.

mkdir ../libvpx-build && cd ../libvpx-build: The libvpx developers recommend building in a dedicated build directory.

--disable-vp8: This switch prevents building of VP8 codec support.

--disable-vp9: This switch prevents building of VP9 codec support.
