使用 turbojpeg 报错 请问是什么原因

[xiaowen0407]

报错原因：Instance has not been initialized for decompression
但不知道到是哪个没实例化 困扰了很久
附上代码
bool MJPG2BGRA(const k4a::image&mjpgimage, k4a::image&bgraimage)
{

bgraimage = k4a::image::create(K4A_IMAGE_FORMAT_COLOR_BGRA32,
	mjpgimage.get_width_pixels(),
	mjpgimage.get_height_pixels(),
	mjpgimage.get_width_pixels() * 4 * (int)sizeof(uint8_t));
tjhandle m_decompressor;
m_decompressor = tjInitCompress();
const int decompressStatus = tjDecompress2(m_decompressor,
	mjpgimage.get_buffer(),
	static_cast<unsigned long>(mjpgimage.get_size()),
	bgraimage.get_buffer(),
	mjpgimage.get_width_pixels(),
	0,
	mjpgimage.get_height_pixels(),
	TJPF_BGRA,
	TJFLAG_FASTDCT | TJFLAG_FASTUPSAMPLE);
if (decompressStatus != 0)
{
	printf("解压失败:\n");
	printf("原因是:%s", tjGetErrorStr());
}
(void)tjDestroy(m_decompressor);
return true;

}
