Crate av_decoders 

Ready-made decoders for the rust-av ecosystem.

Each decoder outputs v_frame structs. Only the y4m decoder is enabled by default; others require Cargo features for their external dependencies.

Backend priority

1. Y4M — .y4m/.yuv files (always available, lowest overhead)
2. FFMS2 — when the ffms2 feature is enabled
3. FFmpeg — when the ffmpeg feature is enabled
4. VapourSynth — when the vapoursynth feature is enabled

Example

use av_decoders::Decoder;

let mut decoder = Decoder::from_file("video.y4m")?;
let details = decoder.get_video_details();
println!("{}x{} @ {} fps", details.width, details.height, details.frame_rate);

while let Ok(frame) = decoder.read_video_frame::<u8>() {
    // process frame
}

Re-exports

pub use v_frame;

Y4mDecoder

YUV4MPEG2 decoder.

Enums

DecoderError

Errors that can occur during video decoding operations.
