Struct AsyncImageDecoder 

pub struct AsyncImageDecoder { /* private fields */ }

Async wrapper around ImageDecoder.

Both open (file I/O + codec init) and decode (pixel conversion) are performed on spawn_blocking threads so the async executor is not blocked.

There is no into_stream method because an image is a single frame, not a sequence.

Examples

use ff_decode::AsyncImageDecoder;

let frame = AsyncImageDecoder::open("photo.png").await?.decode().await?;
println!("{}x{}", frame.width(), frame.height());

Implementations

impl AsyncImageDecoder

pub async fn open( path: impl AsRef<Path> + Send + 'static, ) -> Result<Self, DecodeError>

Opens the image file asynchronously.

File I/O and codec initialisation are performed on a spawn_blocking thread so the async executor is not blocked.

Errors

Returns DecodeError if the file is missing, contains no video stream, or uses an unsupported codec.

pub async fn decode(self) -> Result<VideoFrame, DecodeError>

Decodes the image into a VideoFrame.

This consuming method runs on a spawn_blocking thread.

Errors

Returns DecodeError on codec or I/O errors.
