jpg compatibility issues

[rich2005]

The interlaced problem with jpeg files for media players / video picture frames goes back a while.

From memory Gimp 2.6 saved (is now exported) with a non progressive as default. An equal PITA for those who needed progressive. The majority won.

You have Imagemagick, easy enough to bulk convert the lot (be careful and practise with a some copies first)

Code:

mogrify -interlace none *.jpg    

some edited output as an example

rich@nova:/mnt/ramdisk$ identify -verbose default-gimp.jpg
Image: default-gimp.jpg
 Format: JPEG (Joint Photographic Experts Group JFIF format)
 Mime type: image/jpeg
.........
Interlace: JPEG
 
rich@nova:/mnt/ramdisk$  mogrify -interlace none *.jpg
