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.
Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Download size: 5.4 MB
Estimated disk space required: 68 MB (add 1.6 GB for tests)
Estimated build time: 0.5 SBU (Using parallelism=4; add approx 11 SBU for tests using parallelism=4, including download time)
yasm-1.3.0 or NASM-2.16.03, and Which-2.21 (so configure can find yasm)
cURL-8.10.1 (to download test files) and Doxygen-1.12.0 (to build documentation)
An Internet connection is needed for some tests of this package.
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 many files as part of its test process. A few parts of it will use all available cores.
Now, as the root
user:
make install
sed ... : This command corrects the ownership and permissions of installed files.
mkdir libvpx-build && cd libvpx-build: The libvpx developers recommend building in a dedicated build directory.
--disable-static
: This
switch prevents installation of static versions of the libraries.
--disable-vp8
: This switch prevents
building support for the VP8 codec.
--disable-vp9
: This switch prevents
building support for the VP9 codec.
--target=generic-gnu
: This switch
disables optimizations specific to x86 and x86-64, allowing to
build this package without nasm and yasm installed.
LD_LIBRARY_PATH=.: This is needed for the test suite to use the library that was just built.
