libvpx-v1.3.0

Introduction to libvpx

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-7.5 platform.

Package Information

The libvpx tarballs are no longer generated by the maintainers. To build from source, the libvpx developers recommend using current git. The source tarball shown above was created by the BLFS team by pulling a git version, and removing .git, .gitattributes and .gitignore. BLFS made no changes to the existing source files.

libvpx Dependencies

Required

yasm-1.3.0 (compiling with NASM-2.11.05 is currently broken) and Which-2.20 (so configure can find yasm)

Optional

Doxygen-1.8.8 and PHP-5.5.16 (to build the documentation).
