Struct VideoDecoder 

pub struct VideoDecoder { /* private fields */ }

Video decoder with hardware acceleration support.

Implementations

impl VideoDecoder

pub fn new<P: AsRef<Path>>(path: P, hw_accel: HwAccel) -> VideoResult<Self>

Create a new video decoder and start decoding.

Automatically attempts hardware acceleration and falls back to software with a diagnostic warning if the hardware path cannot be set up.

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

Get the next decoded frame (non-blocking).

pub fn metadata(&self) -> &VideoMetadata

Get video metadata.

pub fn decoder_info(&self) -> DecoderInfo

Get decoder information for diagnostics (reflects the backend actually in use).

pub fn hw_accel_in_use(&self) -> HwAccel

The hardware backend currently in use by the decode thread. The decode thread reports the real backend shortly after startup (it may fall back from a requested hw backend to software), so this polls briefly until the report lands.

pub fn pause(&self)

Pause decoding (the decode thread stops producing frames).

pub fn resume(&self)

Resume decoding.

pub fn seek(&self, timestamp: Duration)

Seek the underlying stream to a timestamp. Frames already queued are stale after the seek, so call VideoDecoder::drain afterwards.

pub fn drain(&mut self)

Drop all frames still queued for consumption (used after a seek).

pub fn is_video_file<P: AsRef<Path>>(path: P) -> bool

Check if this file is a supported video format.

Trait Implementations

impl Drop for VideoDecoder

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl VideoSource for VideoDecoder

fn metadata(&self) -> &VideoMetadata

Get video metadata.

fn decoder_info(&self) -> DecoderInfo

Get decoder information.

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

Get the next decoded frame (non-blocking).

fn is_video_file(path: &Path) -> bool

Check if this is a video file.
