I don't think this change makes sense as is. x264 built with 10 bit
support does not accept raw 8 bit video and vice versa (and has to be
configured differently), and x264 build with 10 bit support does only
support different h264 profiles than the 8 bit version. And these 10 bit
profiles are usually not supported by hardware decoders.
Software currently uses the #defines in x264_config.h to get the
capabilities of the library at build time. If suddenly the library gets
replaced by one with different build parameters, software will stop
working correctly because of that.
Ideally x264 would allow using different bit depths in the same build,
or at least a different soname should be used for the resulting library.
