Can the relevant updates be pulled in for lucid?
Note that x264 doesn't appear to have any runtime detection for the availability of NEON yet, so 2 flavours will need to be built (in the same way as is currently done for the ffmpeg-debian package). NEON is built in by default unless CFLAGS contains explicit -march, -mfpu options: to get vanilla binaries which will run across all ARMv7 implementations, you would need to configure with CFLAGS= '-march= armv7-a' (or change the configure script).
