FS#13269 - Image Viewer is broken in recent builds

All images give me “Data abort at 30 FSR 0×8…” error or displayed as black screen.

Found on daily build made on 210205 (and same error on latest)

Attached “cover.jpg” works properly in 3.15 release

   cover.jpg (1.42 MiB)
   config.cfg (0.2 KiB)

Need more info:

What is your config like?
Are you playing music at the time? (filetype?)
size of images?
upload of a failing image greatly appreciated

It's broken for all images I tried. Though I only tried for cover.jpg images placed in folders with music. No matter music is playing or not. Attached example with image and config.cfg to task description

Huh.. Strange. Data abort is no longer reproducible for me .. But all images are shown as black screen instead.

And another example with different error. Maybe not related. This one gives "unsupported -4" and it's also not shown on WPS.

this (27kb image) is actually a JFIF file its a bitmap in jpeg clothing

W10 by chance?

the cover art above (1.42 mb image) is also JFIF

bahus commented on 2021-03-10 14:08

Yes W10. But all images were downloaded elsewhere - I didn't save them myself..

I've just installed version 3.15 and Cover art is displayed properly. 27 kb image still gives me "unsupported -4" error.

Oops my mistake I was thinking EXIF I guess JFIF is not the issue

I'm testing on a ClipZip as well and I got a data abort on one of the files one of the times I loaded it

so I'll call this confirmed but IDK what the root cause is yet

The 27Kb image is not a supported

the decoder says
0xC2: /* SOF Huff - Progressive DCT*/
/* other DCT model than baseline not implemented */

Think I got the data abort fixed

Note:
If using greyscale it appears you need dithering to get it to work?

bahus commented on 2021-03-11 04:59

Yes it works now. Tested on my Sansa Clip Zip and Sansa Clip+. Thank you!
