convertNV21ToRGB function
Implementation
void convertNV21ToRGB(Uint8List yuvBytes, Uint8List vuBytes, int width, int height, image_lib.Image image) {
// Conversion logic from NV21 to RGB
// ...
// Example conversion logic using the `imageLib` package
// This is just a placeholder and may not be the most efficient method
for (var y = 0; y < height; y++) {
for (var x = 0; x < width; x++) {
final yIndex = y * width + x;
final uvIndex = (y ~/ 2) * (width ~/ 2) + (x ~/ 2);
final yValue = yuvBytes[yIndex];
final uValue = vuBytes[uvIndex * 2];
final vValue = vuBytes[uvIndex * 2 + 1];
// Convert YUV to RGB
final r = yValue + 1.402 * (vValue - 128);
final g = yValue - 0.344136 * (uValue - 128) - 0.714136 * (vValue - 128);
