Video support

[solarmystic]

It seems that since build 0.7.6-1073, when oioitff's commit (https://github.com/hrydgard/ppsspp/commi...d6e745ae6) was merged to master, there has been a regression of sorts in terms of how PPSSPP displays certain games' FMV cutscenes.

In some games, the FMVs used to display the video nicely (but with distorted audio), for example, FF Type 0 and Mortal Kombat Unchained.

Since build 0.7-6-1073, the videos are not displayed at all, but you can still hear the audio in the background.

Only certain games seem to be affected. I'm still in the process of testing individual games seperately to see how many of them are affected.
