I want to capture RAW picture from webcam, But I do not want to use JPG, Because it makes the picture bad and full of noise.

I can shoot a RAW video using this code, and also can open the file using VLC without any problems. 

gst-launch-1.0 -q v4l2src ! video/x-raw,width=1280,height=720,framerate=10/1 ! avimux ! filesink location=test.avi

Also i can shoot a RAW picture using this code. 

gst-launch-1.0 v4l2src num-buffers=1 ! video/x-raw,width=1280,height=720,framerate=10/1 ! filesink location=test.raw

But the problem is that the file does not open using a photo editor such as GIMP.

RAW YUV 4:2:2 file you can download

My OS is Ubuntu.

Is the problem in the Gstreamer? (Maybe need to convert picture, but without loss details, How?)

Is the problem in the GIMP? (Maybe does not support RAW, what alternative?)

PNG is lossless formate, so maybe ther's no difference between RAW and PNG except PNG file size is smaller than RAW file size. 

gst-launch-1.0 v4l2src num-buffers=1 ! video/x-raw,width=1280,height=720,framerate=10/1 ! videoconvert ! pngenc snapshot=false compression-level=1 ! filesink location=img-test.png
