Problems with JPG?!
Dear GIMP-Team,
I can not display images that I have prepared and saved with GIMP 2.8.14
(under Windows 10) in jpg-format on my TV or via a digital box (WD TV).
On my PC its no problem!
The Thumbnailes can be seen but the images can not be read!
I have also tried several setting for the jpg-saving.
Other images I prepared with former versions are working well!
Do you have an idea or information !?
Kind regards
Stefan Rohde

Can you create a GIMP bug ticket on bugzilla.gimp.org and attach a sample JPEG image that is broken?

Hi Stefan,
did you also try various settings of the subsampling (in the German dialog box: Zwischenschritte, although 'Farbunterabtastung' is the proper translation here)? If you report a bug, please make sure to use version 2.8.16 which is the latest.
Greetings
Sven

Can you send us a sample image ? It is possible that your television implements only a subset of the JPEG standard. To verify , can you let me know if the following JPEG file that I first converted to PNG using ImageMagick and then saved as JPEG From GIMP is fine:
* http://www.shlomifish.org/Files/files/images/chickpeas.xcf.bz2
* http://www.shlomifish.org/Files/files/images/chickpeas-from-xcf.png
* http://www.shlomifish.org/Files/files/images/chickpeas-from-xcf.jpg
The SHA-256 sums for them are:

Can you give an example of a JPEG file that your television views properly?

It's most likely the Progressive option in the advanced part of the JPEG export dialog.

Yes it's almost certainly the bug that won't get fixed raising it's ugly head again: https://bugzilla.gnome.org/show_bug.cgi?id=723153

Manufacturers simply aren't going to fix their firmware, particularly for older devices (read: are already on the market). And it's possible that a firmware fix wouldn't even be enough, since printers would need more memory to buffer the entire image rather than just reconstituting it one row of blocks at a time. There's also the added testing expense. Phones and cameras don't generate progressive JPEGs, so printer, TV, etc. manufacturers don't have any real incentive to support them. The manufacturers probably don't even write their own firmware; they contract it out.
Progressive JPEGs are nice for displaying big images in browsers over slow links (which my 1500/368 DSL qualifies as). I admit that they're easier for me in that context. But given the confusion this is causing, and that it requires non-trivial knowledge (and tools) for people to fix after the fact, I'd argue that this should be revisited.
