Video frame playback scheduling

摘要

Systems and techniques are provided for video frame playback scheduling. A presentation time for a frame of a video may be received. An offset for the frame of video may be determined based on succeeding frames of the video and Vsync pulse times. The presentation time for the frame of the video may be adjusted based on the offset to generate an adjusted presentation time that is closer to a halfway point between a first Vsync pulse and a second Vsync pulse than the presentation time. A cumulative time correction may be tracked based on adjustments made to the presentation times for frames of the video. A magnitude of the cumulative time correction may be determined to exceed the magnitude of a positive or negative threshold. The cumulative time correction may be added to or subtracted from based on the determination that the magnitude exceeds the positive or negative threshold.

主权项

1. A computer-implemented method performed by a data processing apparatus, the method comprising:
receiving a presentation time for a frame of a video; determining an offset for the frame of the video based on at least one succeeding frame of the video and at least one Vsync pulse time; and adjusting the presentation time for the frame of the video based on the offset to generate an adjusted presentation time that is closer to a halfway point between a first Vsync pulse and a second Vsync pulse than the presentation time.
