Variable Documentation

mlt_frame_processing_mutex

pthread_mutex_t mlt_frame_processing_mutex = PTHREAD_MUTEX_INITIALIZER

mlt_frame_s::is_processing can not be made atomic, so protect it with a mutex.

mlt_sdl_mutex

pthread_mutex_t mlt_sdl_mutex = PTHREAD_MUTEX_INITIALIZER

Define this if you want an automatic deinterlace (if necessary) when the consumer's producer is not running at normal speed.

This is not the ideal place for this, but it is needed by VDPAU as well.
