Plex Web Client FLAC Direct Play Support

Add FLAC support for Plex web client

Chrome 56+ / Firefox 52+
Might not work on all OSes

Add the following to /usr/lib/plexmediaserver/Resources/Profiles/Web.xml within the <Client> section:

  <DirectPlayProfiles>
    <MusicProfile container="flac" codec="flac" />
  </DirectPlayProfiles>

Included my Web.xml as an example. I just added <DirectPlayProfiles> to Plex Media Server 1.5.5.3634 stock Web.xml.

Web.xml
