ALLEGRO_VIDEO_POSITION_TYPE — Allegro 5 API
#include <allegro5/allegro_video.h> typedef enum ALLEGRO_VIDEO_POSITION_TYPE ALLEGRO_VIDEO_POSITION_TYPE;
Used with al_get_video_position(3) to specify which position to retrieve. If these get out of sync, audio and video may be out of sync in the display of the video.
- ALLEGRO_VIDEO_POSITION_ACTUAL - The amount of time the video has been playing. If the video has audio then this value can be ahead of ALLEGRO_VIDEO_POSITION_VIDEO_DECODE when video decoding lags.
- ALLEGRO_VIDEO_POSITION_VIDEO_DECODE - The amount of video that has been decoded. This may lag behind the "actual" and audio positions if decoding is slower than realtime.
- ALLEGRO_VIDEO_POSITION_AUDIO_DECODE - The amount of audio that has been decoded. This may be the same as ALLEGRO_VIDEO_POSITION_ACTUAL if audio decode is driving the position, which is common to keep audio and video in sync.
