ffmpeg | branch: master | Reimar Döffinger <Reimar.Doeffinger at gmx.de> | Sun Sep 7 13:55:23 2014 +0200| [70d80ed40fa33e3981aed1bf89536b2272cff925] | committer: Reimar Döffinger
qdm2: Allow hard-coding VLC tables.
Also adds a lot of infrastructure necessary for it.
Some of it is a bit ugly though.
Increases binary size for hardcoded tables by about 12 kB,
which is about 15 kB from qdm2_table minus data and code
saved that was only used for creating it.
