Struct VideoPlayback 

pub struct VideoPlayback { /* private fields */ }

Video playback state manager.

Implementations

impl VideoPlayback

pub fn new() -> Self

Create a new video playback manager.

pub fn start( &self, path: &Path, hw_accel: HwAccel, ) -> VideoResult<VideoMetadata>

Start video playback from a file, replacing any active playback.

pub fn stop(&self)

Stop video playback and release all resources immediately.

pub fn pause(&self)

Pause playback: the display loop keeps presenting the last frame, the scheduler freezes its clock, and the decode thread stops decoding so the CPU stays idle.

pub fn resume(&self)

Resume playback after a pause.

pub fn seek(&self, timestamp: Duration) -> VideoResult<()>

Seek to a specific timestamp. Both the scheduler clock and the decoder stream are repositioned, and stale queued frames are discarded.

pub fn next_frame(&self) -> Option<VideoFrame>

Pull the next frame that should be presented.

Returns Some(frame) when a new frame must be uploaded to the GPU, and None when the currently shown texture should be presented unchanged (duplicate frame, decoder behind, or playback paused).

pub fn wait_first_frame(&self, timeout: Duration) -> Option<VideoFrame>

Block until the first frame is available or the timeout elapses.

Used at commit time so the transition’s incoming image is the video’s actual first frame instead of a black placeholder.

pub fn current_frame(&self) -> Option<VideoFrame>

Get the last presented frame without advancing playback.

pub fn metadata(&self) -> Option<VideoMetadata>

Get video metadata of the active playback.

pub fn decoder_info(&self) -> Option<DecoderInfo>

Get decoder diagnostics for the active playback.

pub fn hw_accel_in_use(&self) -> HwAccel

The hardware backend actually used by the active decoder.

pub fn position(&self) -> Option<Duration>

Get the current playback position.

pub fn is_paused(&self) -> bool

Check if playback is paused.

pub fn is_playing(&self) -> bool

Check if a video is currently active.

Trait Implementations

impl Default for VideoPlayback

fn default() -> Self

Returns the “default value” for a type.
