旋转CMSampleBuffer / CVPixelBuffer

Question

我目前正在尝试更改CMSampleBuffer的方向，首先将其转换为CVPixelBuffer，然后使用vImageRotate90_ARGB8888转换缓冲区。我的代码的问题是当vImageRotate90_ARGB8888执行时，它会立即崩溃。我知道有答案（如this one或this one），但所有这些解决方案都无法在我的情况下工作，我真的找不到任何类型的错误，或者想到任何会导致这种情况的错误行为。我目前的代码如下：

- (CVPixelBufferRef)rotateBuffer:(CMSampleBufferRef)sampleBuffer {
CVPixelBufferRef pixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer);
CVPixelBufferLockBaseAddress(pixelBuffer, 0);

size_t bytesPerRow = CVPixelBufferGetBytesPerRow(pixelBuffer);
size_t width = CVPixelBufferGetWidth(pixelBuffer);
size_t height = CVPixelBufferGetHeight(pixelBuffer);
size_t currSize = bytesPerRow * height * sizeof(unsigned char);
size_t bytesPerRowOut = 4 * height * sizeof(unsigned char);

OSType pixelFormat = CVPixelBufferGetPixelFormatType(pixelBuffer);

void *baseAddress = CVPixelBufferGetBaseAddress(pixelBuffer);
unsigned char *outPixelData = (unsigned char *)malloc(currSize);

vImage_Buffer sourceBuffer = {baseAddress, height, width, bytesPerRow};
vImage_Buffer destinationBuffer = {outPixelData, width, height, bytesPerRowOut};

uint8_t rotation = kRotate90DegreesClockwise;

Pixel_8888 bgColor = {0, 0, 0, 0};
vImageRotate90_ARGB8888(&sourceBuffer, &destinationBuffer, rotation, bgColor, kvImageNoFlags); // Crash!

CVPixelBufferRef rotatedBuffer = NULL;
CVPixelBufferCreateWithBytes(kCFAllocatorDefault, destinationBuffer.width, destinationBuffer.height, pixelFormat, destinationBuffer.data, destinationBuffer.rowBytes, freePixelBufferData, NULL, NULL, &rotatedBuffer);

CVPixelBufferUnlockBaseAddress(pixelBuffer, 0);

return rotatedBuffer; 
}

void freePixelBufferData(void *releaseRefCon, const void *baseAddress) {
free((void *)baseAddress);
}
