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;

}

@k1995 5555 好的 谢谢哈

求助啊啊啊啊啊 啊 啊

用kinect sdk录制视频视频时候保存格式位jpeg 所以要解压成bgra格式但是在做图片解压时候报错 instance has not been initialized for decompression 不知道这个是什么意思
下面是网上找的解压函数 但是不对报错就报上面那个
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 = tjInitCompress();

          if (tjDecompress2(m_decompressor,

                       mjpgimage.get_buffer(),//输入图片的数据数组取出

                       static_cast<unsigned long>(mjpgimage.get_size()),

                       bgraimage.get_buffer(),//输入图片的数据存储在转换的图片上

                       mjpgimage.get_width_pixels(),

                       0,

                       mjpgimage.get_height_pixels(),

                       TJPF_BGRA,

                       TJFLAG_FASTDCT | TJFLAG_FASTUPSAMPLE)!=0)

          {

                       printf("解压失败");

          }

          (void)tjDestroy(m_decompressor);

return ture;
