            Bug ID: 334678
           Summary: Thumbnails fail to generate for certain AVI files -
                    infinite loop
    Classification: Unclassified
           Product: digikam
           Version: 3.5.0
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Thumbnails
          Assignee: digikam-devel at kde.org
          Reporter: stephen_bainbridge at yahoo.co.uk

Certain AVI files fail to get thumbnails generated, whenever Digikam tries to
extract the thumbnail for these files it will loop indefinately, consuming 100%
CPU.

Dolphin shows the thumbnails correctly.

If I check the AVI with ffmpeg, for example:

  ffmpeg -v error -i bike.AVI -f null -

it kicks back an error:

  [mjpeg @ 0x1e3c660] overread 8

So there does seem to be an issue with the AVI (even though it plays fine), but
I would expect Digikam to at least display a default thumbnail and not
continually loop.




Reproducible: Always

Steps to Reproduce:
1. Copy suspect AVI into photo folder
Actual Results:  
No thumbnail will be generated and one core on the CPU will stick at 100% CPU
busy for the digikam process/thread.

Expected Results:  
Should generate a thumbnail or a default one and not continually loop.
