使用ffmpeg或OpenCV处理.Raw图像(Processing .Raw images using ffmpeg or OpenCV)

在阅读RAW图像格式的维基百科页面之后 ，这是任何图像的数字负片。

要查看或打印，必须处理相机图像传感器的输出，即将其转换为场景的照片渲染，然后以JPEG等标准光栅图形格式存储。 这种处理，无论是在相机内还是以后在原始文件转换器中完成，都涉及许多操作，通常包括

我使用v4l2示例从Logitech c920中抓取了一些.raw文件，但是当我显示图像时，它看起来像这样： 一个原始图像，在其他帧中，我可以看到我的影子

有谁知道如何处理这些文件来查看完整的框架？

这里是原始.raw文件的链接

After reading Wikipedia page of Raw image format which is the digital negative of any image.

To be viewed or printed, the output from a camera's image sensor has to be processed, that is, converted to a photographic rendering of the scene, and then stored in a standard raster graphics format such as JPEG. This processing, whether done in-camera or later in a raw-file converter, involves a number of operations, typically including

I have some .raw files grabbed from my Logitech c920 using v4l2 example but when I display the image it looks like this: a raw image where in other frames I can see my shadow

Does anyone knows how to process such files to see the complete frame ?

Here is a link to the original .raw file

最满意答案

ffmpeg -f rawvideo -s 640x480 -pix_fmt yuyv422 -i frame-1.raw frame-1.jpg

这些选项是基于链接的v4l2代码设置的，并且生成的图像是您期望获得的图像。

ffmpeg -f rawvideo -s 640x480 -pix_fmt yuyv422 -i frame-1.raw frame-1.jpg

The options were set based on the v4l2 code linked, and the resulting image is the one you would expect to get.
