Struct VideoStream 

pub struct VideoStream { /* private fields */ }

A running decoder and the frames it produced. Dropping it kills the decoder.

Implementations

impl VideoStream

pub fn spawn( command: Command, (width, height): (u32, u32), frames_per_second: u32, ) -> Result<Self>

Run command, which must write width x height RGBA frames back to back on its standard output at frames_per_second.

pub fn ffmpeg<S: AsRef<OsStr>>( input: &[S], size: (u32, u32), frames_per_second: u32, ) -> Result<Self>

Decode with ffmpeg. input holds ffmpeg’s input arguments, such as ["-ss", "12", "-i", "clip.mp4"]. We letterbox the picture to size and drop the sound.

pub fn latest(&mut self) -> Option<Vec<u8>>

The newest frame the clock has passed since the last call, or None when no new frame is due or decoded yet. We skip the frames in between, so a slow terminal drops frames and the picture keeps pace with the clock.

pub fn shown(&self) -> u32

How many frames the stream has handed out or skipped.

pub fn ended(&self) -> bool

Whether the decoder finished and every frame went out.

Trait Implementations

impl Debug for VideoStream

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for VideoStream

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.
