ditto my content/...gn question about 'enable_hevc_demuxing'. Pardon my GN
noob-ness. I get that 'defines' aren't for exporting, but is the underlying
'enable_hevc_demuxing' the same entity as in content/...gn?

This file imports the media_options.gni file so it's all good.

[servolk, 2015/09/03 00:17:51]

Yes, in this case we are importing enable_hevc_demuxing flag from
//media/media_options.gni, and if that flag is set, we'll define the
ENABLE_HEVC_DEMUXING C++ macro for the code to use.
