Using something like libvpx directly probably isn't the best. Are
individual frames needed or is it just going to be rendered into an
OpenGL context? If the former, I'd recommend ffmpeg (GPL with certain
codecs enabled (namely x264 and x265), LGPL otherwise). If the latter,
libmpv[1] might be a simpler API (with support for controls and the like
already there). It has an LGPL flag to disable the GPL bits (they're in
the process of relicensing[2]) which shouldn't affect the library too
much.
