Description rfeg 2021-08-28 10:36:48 UTC 
SUMMARY

STEPS TO REPRODUCE:
1. import iPhone photos to album
2. double-click on thumb
3. when image is opened hit -> or <- key
4. measure time to show next image

OBSERVED RESULT: takes about to show next picture after hitting -> or <- keys

EXPECTED RESULT: should take less than one second like JPEG and RAW files (it is very fast)

SOFTWARE/OS VERSIONS: macOS with M1 (using Rosetta) 

ADDITIONAL INFORMATION: if you press -> several times the files strip moves several times but big image is still the same until finally shows image selected (that is not visible in the film strip); 
it seems that is not a Mac/M1 related thing, since other images show very fast. 
It occurs also in version 7.2.0.
Note: this is my first bug submission, sorry for any missing info, please be kind
Comment 1 caulier.gilles 2021-08-28 11:19:16 UTC 
Actually, the libheif/libde265 are compiled in digiKam core (code is included as well without any optimization at compilation).

https://invent.kde.org/graphics/digikam/-/tree/master/core/libs/heifutils

The plan is to remove this code and to use the system based library, which must include optimizations.

Comment 2 caulier.gilles 2021-08-28 11:21:12 UTC 
Anther point is the cache memory used to store pre-loaded images. Under MacOS, a fix have been added to current code to detect properly the amount of MacOS RAW available. This can improve speedup of preview loading.

Comment 3 rfeg 2021-08-28 22:06:16 UTC 
thanks for the info, but my comment/bug is the big difference of time needed to process and display the embedded JPEG preview from a HEIF iPhone file vs a RAW file (HEIF is slow, RAW is fast).

@Caullier: do you think that using native library will fix this? will HEIF native library be included in ver 8.0
Comment 4 Maik Qualmann 2021-09-02 05:50:52 UTC 
A current log from the digiKam start of the last MacOS package would be nice.

Git commit f6ec12dfb701d1d77be979dee7c72537551af86d by Gilles Caulier.
Committed on 03/03/2022 at 10:34.
Pushed by cgilles into branch 'qt5-maintenance'.

Remove internal libheif and libde265 from digiKam core in favor of system libraries
to inherits of last decoding optimizations and native accelerations.
Show libheif version in Components Info dialog.
Tested with AppImage bundle compilation workflow.
TODO check Linux native, MacOS, and Windows targets.

Comment 11 caulier.gilles 2022-03-03 13:17:17 UTC 
Hi Maik,

I mostly completed to drop of libheif/libde265 from digiKam core in qt5-maintenance branch. I will backport all commits to master of course.

Looking into libgd heif loader, i discovered this definition :

https://github.com/libgd/libgd/blob/master/src/gd_heif.c#L23

... used to allocate the heif context. 

https://github.com/libgd/libgd/blob/master/src/gd_heif.c#L125

The question is why to use this value ? It's an optimization ?

Gilles
Comment 12 Maik Qualmann 2022-03-03 14:14:22 UTC 
Yes, that's an optimization if you don't know how much memory is required. It's faster to request larger blocks than to constantly expand with small blocks. Something similar for QVector with QVector::reserve().

https://doc.qt.io/qt-5/qvector.html#reserve

Maik
Comment 13 caulier.gilles 2022-03-03 14:15:36 UTC 
MAik,

Do you think we needs something like that in HEIF image loader ?

Gilles

Comment 17 Maik Qualmann 2022-03-03 14:22:43 UTC 
I don't think we need it. We know the final size of the memory needed for the DImg and allocate it completely with width x height x 4(8).

Comment 28 caulier.gilles 2024-06-18 11:22:20 UTC 
Note: Libheif 1.17.6 provide now an option to use ffmpeg accelerated codec to process HEVC data.

Comment 29 Maik Qualmann 2024-06-18 16:32:04 UTC 
This FFmpeg plugin is already available here under openSUSE and is currently unusable. It must be uninstalled and replaced by the HEIF decoder. In the first versions it crashed, now a few HEIF files are displayed, but most are not. FFmpeg then often reports the EOF error in the console.
