Flutter yuv 转 rgb

mldxs2023-09-10 9:45

1、引用yuv_converter库

yuv_converter: ^0.0.1

2、导入头文件：

import 'package:yuv_converter/yuv_converter.dart';

3、yuv转rgb

YuvConverter.yuv420NV21ToRgba8888(yuvRawData, 512, 512)

根据yuv格式选择不同的api。

举个例子：

void initState() {
    super.initState() ;
    loadAssetAsUint8List("assets/yuv/1_uyvy.yuv").then((yuvRawData){
      rgbga1 = YuvConverter.yuv422uyvyToRgba8888(yuvRawData, 512, 512) ;
      setState(() {

      });
    }) ;

    loadAssetAsUint8List("assets/yuv/1_nv21.yuv").then((yuvRawData){
      rgbga2 = YuvConverter.yuv420NV21ToRgba8888(yuvRawData, 512, 512) ;
      setState(() {

      });
    }) ;
  }

  Future<Uint8List> loadAssetAsUint8List(String assetPath) async {
    // 使用rootBundle加载assets中的文件
    final ByteData data = await rootBundle.load(assetPath);

    // 将ByteData转换为Uint8List
    final Uint8List uint8List = data.buffer.asUint8List();

    return uint8List;
  }
