sample file from ffmpeg bug report

Indeed it does not happen to every h264 video.

I have checked h264 codec feature in ffmpeg and it is listed same as in your
screenshot.

I have also tested different files:
* video converted to h264 using handbrake : plays correctly.
* video recorded with codec h264 directly on the camera in fullhd settings :
plays correctly
* video recorded with codec h264 directly on the camera in 4K settings :
doesn't play and error about hardware decoding in the logs.

I should add that the same files that now cause issues (4K h264 from the
camera) where fine in previous versions of digikam (i may have missed a few
updates but quite sure 8.0.0 was ok). Have been using the same camera settings
for a few years now without issues in digikam.

I cannot had my sample here (4K gets too large for file size limit); but here
is a temporary link :

I can also confirm that the sample from ffmpeg bug report does indeed not play
in digikam and show the same error in logs
