Broken sword 2.5 Video speed

Description

Hi, unfortunately on a Raspberry Pi 3 the video playback speed of Broken Sword 2.5 is way too slow here.

Not sure why, I already tried some scaler, size or OpenGL-settings but without success.

There are a few tickets already about issues with video for the game.
https://bugs.scummvm.org/ticket/7063

Do you also get the freeze issue on video playback?
Is video framerate slow but audio plays at normal speed resulting in desynch?

Here's the most relevant info I have about the potential cause for this (from sev, via ScummVM Discord):

the primarily problem of that behaviour of BS2.5 is very hard to fix
the whole game engine is a Lua interpreter, thus, the main rendering loop is in Lua (...) setting up z coordinate of the menu below the game screen or video screen, so it is always rendered at 800x600 32-bit with transparency

Hi, I`ve not recognized a freeze, audio seems to be ok, too as far as I can tell...its just the video playing very slow somehow

We can not do anything with it. Theora video playback is very resource-demanding.
