udfread is a submodule of libbluray and **should** be **statically** linked within libbluray. Could someone do a couple of things? From the HandBrake build directory, ```ls -l contrib/lib```. Also ```ldd...

HandBrake's build system should not be linking to distro supplied version of libbluray. Did you modify HandBrake's build system to do so?

Does your distro install a static version libbluray? i.e. libbluray.a rather than libbluray.so? It shouldn't really matter. HandBrake's build system should be linking the version of libbluray that we build....

FYI, this touches `macosx/HBJob+HBJobConversion.m`. It's a simple one-liner that should be safe, but might want to test to be certain.

Although the logic for selecting the "best" of linked tracks will get more complex. Which is better aac vs. ac3? May want to add channel count and sample rate as...

Turns out adding mp4 fallback was more invasive than I thought. There can be multiple fallbacks which required turning the "link" into a "link list". But code is written. Just...
