Only with jpg made with a smartphone or from WhatsApp messages there is following error Message:

Error converting to JPEG, 'D:\1Daten\4.jpg' to 'D:\1Daten\4.jpg'
[mjpeg @ 0000020a06c5e7c0] unable to decode APP fields: Invalid data found when processing input
[mjpeg @ 0000020a06c60800] unable to decode APP fields: Invalid data found when processing input


Since the error occurs more frequently and thus makes the image converter useless, I write a post to this support forum. Please fix this error. With other jpgs is no problem. If the admin send me an Email, I can send a example jpg.
