This package, from the WebM project, provides the reference implementations of the VP8 Codec, used in most current html5 video, and of the next-generation VP9 Codec.
This package is known to build and work properly using an LFS-11.0 platform.

Download size: 5.1 MB
Estimated disk space required: 64 MB (add 1.3GB if running tests)
Estimated build time: 1.5 SBU, add 41 SBU if running tests, including download time
yasm-1.3.0 or NASM-2.15.05, and Which-2.21 (so configure can find yasm)
cURL-7.78.0 (to download test files) and Doxygen-1.9.2 (to build documentation)
User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/libvpx
Install libvpx by running the following commands:
sed -i 's/cp -p/cp/' build/make/Makefile &&
mkdir libvpx-build &&
cd libvpx-build &&
../configure --prefix=/usr \
--enable-shared \
--disable-static &&
make
To test the results, issue: LD_LIBRARY_PATH=. make test. The test suite downloads several files as part of its test process.
Now, as the root user:
make install
sed ... : This command corrects 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.
--disable-static: This
switch prevents installation of static versions of the libraries.
--target=generic-gnu: This switch
disables optimizations specific for x86 and x86-64, allowing to
build this package without nasm and yasm installed.
LD_LIBRARY_PATH=.: This is needed for the testsuite to use the just built library.
