Struct Encoder 

pub struct Encoder { /* private fields */ }

Encodes frames into a video stream.

Example

let encoder = Encoder::new(
    Path::new("video_in.mp4"),
    Settings::for_h264_yuv420p(800, 600, 30.0)
)
.unwrap();

let decoder = Decoder::new(Path::new("video_out.mkv")).unwrap();
decoder
    .decode_iter()
    .take_while(Result::is_ok)
    .map(|frame| encoder
        .encode(frame.unwrap())
        .expect("Failed to encode frame."),
    );

Implementations

impl Encoder

pub fn new( destination: impl Into<Location>, settings: Settings, ) -> Result<Self, Error>

Create an encoder with the specified destination and settings.

• destination - Where to encode to.
• settings - Encoding settings.

pub fn encode( &mut self, frame: &Frame, source_timestamp: Time, ) -> Result<(), Error>

Encode a single ndarray frame.

Arguments

• frame - Frame to encode in HWC format and standard layout.
• source_timestamp - Frame timestamp of original source. This is necessary to make sure the output will be timed correctly.

pub fn encode_raw(&mut self, frame: RawFrame) -> Result<(), Error>

Encode a single raw frame.

Arguments

• frame - Frame to encode.

pub fn finish(&mut self) -> Result<(), Error>

Signal to the encoder that writing has finished. This will cause any packets in the encoder to be flushed and a trailer to be written if the container format has one.

Note: If you don’t call this function before dropping the encoder, it will be called automatically. This will block the caller thread. Any errors cannot be propagated in this case.

pub fn time_base(&self) -> AvRational

Get encoder time base.
