Hello.
I am currently trying to get MJPEG (motion JPEG) from a WEB camera and convert it with gx_image_reader for display.
The WEB camera I am using is inputting YCbCr 420, but I cannot convert it well.
What formats does gx_image_reader support?

JPEG and PNG image formats are currently supported. In your case, if you have a Motion JPEG (MJPEG) file, you can split it into individual JPEG images. Then, you can utilize the image reader to decode each JPEG image separately.
Thanks for the reply.
The MJPEG is imported one screen at a time using USBX UVC.
This imported data seems to be in YCbCr 422 format and the image converted by gx_image_reader is not correct.
Therefore, I am asking this question because I think there is a format that is not yet supported.
Thanks for the reply.
Hopefully this will be fixed later this month.

This is a bug related to GUIX JPEG decoding, at present, only YCbCr420 and YCbCr444 can work correctly. We already addressed this issue internally, the fix will be pushed to GitHub by the end of this month.
