get(t: float) → bytes

time_to_pts(t: float) → int

Convert the actual time to the video stream timestamp

ensure_frames_correct(pts: int) → None

Ensure that pts always satisfies frames[-2].pts <= pts < frames[-1].pts - If pts is slightly after the decoded region (within the tolerance defined by self.pts_tolerance), gradually move the decoded region forward - If pts is before the decoded region, or is too far beyond it, perform a seek to rebuild the decoded region

needs_seek(pts: int) → bool
