the combination of compile time switch and runtime switch is confusing :x

[DaleCurtis, 2015/11/09 21:50:48]

Yeah, hopefully it won't live much longer, the problem is the compile flags add
a fair bit of apk size, so we're waiting until we know we can play EME/premium
content on this path and we have all the fallback mechanisms in place before
committing to it.
