[Mlt-devel] SDL_Preview patch to improve speed

[Jonathan T. <jon...@gm...>]

Dan,
Here is a patch for the SDL_Preview consumer, that increases the speed when
switching between the STILL and SDL consumers.  It does this by
*not*calling the SDL_InitSubSystem( SDL_INIT_AUDIO ) and
SDL_QuitSubSystem(
SDL_INIT_AUDIO ) methods every time it switches, but rather when the SDL
Preview consumer is started and stopped.  I have tested this patch against
OpenShot when using the regular SDL consumer and the SDL Preview consumer.
 I can't make it break, so I feel pretty good about it.

Please let me know if you see any potential issues with the patch.

Thanks!
-Jonathan
