Expand description

Results of VFR analysis on a video stream.

Fields§

§is_variable_frame_rate: bool

Whether the stream appears to be variable frame rate.

This is true when the standard deviation of frame durations exceeds 10% of the mean frame duration.

§mean_frame_duration: f64

Mean frame duration in seconds.

§frame_duration_stddev: f64

Standard deviation of frame durations in seconds.

§min_frames_per_second: f64

Minimum instantaneous FPS observed.

§max_frames_per_second: f64

Maximum instantaneous FPS observed.

§mean_frames_per_second: f64

Mean FPS (1 / mean_frame_duration).

§frames_analyzed: u64

Number of frames analyzed.

§pts_list: Vec<Duration>

Per-frame PTS values converted to Duration, in decode order.
