yuv's Introduction

YUV formats

This crate implements conversions from YUV/YCbCr formats to RGB. It also contains enums/constants for describing color spaces common in video formats.

Currently it's in an early stage, implementing subset needed for decoding AV1/AVIF.

Implemented

Matrix conversion for BT601, BT709, FCC, BT470BG, SMPTE240
YCgCo (untested)
Identity pass-through (GBR)
Studio and full range colors
8-bit, and 10/12 to 16-bit conversions

`panic` when converting to YUV420 to RGB

I have a raw buffer of bytes which is a YUV420 format frame from a camera, which I am trying to convert to RGB (well, ultimately to a JPEG).

My code, however, panics when I try to do the conversion, looking something like this:

let frame_data: Vec<u8> = ...; // a 1920x1080 resolution YUV420 frame, 3110400 bytes long
let view = Image::<Yuv<u8>, _>::from_buf(&frame_data, 1920, 1080).unwrap();
let mut rgb_buf = Image::<Rgb<u8>, _>::new(0, 0, 0u8);
view.convert(&mut rgb_buf);

And then I get a really long panic message:

thread '<unnamed>' panicked at 'range end index 3116160 out of range for slice of length 3110400', /home/michael/.cargo/registry/src/github.com-1ecc6299db9ec823/ffimage-0.9.0/src/packed/convert/rayon.rs:86:27
