[digikam] [Bug 349924] New: Videos (mp4, mov, avi) do not play under OS X Yosemite when using Digikam.

[Jens B. Benecke]

https://bugs.kde.org/show_bug.cgi?id=349924

--- Comment #20 from Jens B. Benecke <[hidden email]> ---
I tried 4.13.0 but still I cannot play videos in Digikam and face recognition
does not work. (seems not to do anything) Everything else seems to work. But I
also cannot compile my own version of 4.13.0 since just modifying the Macports
4.9.0 portfile (version and SHA) does not work, the compile fails.

Can you share your build scripts / process so I can have a look?

Thank you!

Jens,

I would like your feedback now about the famous video thumbnails and preview in
digiKam.

We don't use anymore the KDE mediaplayer + GStreamer backend. A pure Qt5
solution based on Qt5Multimedia extract video thumbs and render preview.

There is no limitation given by Qt about OSX support :

http://doc.qt.io/qt-5/qtmultimedia-index.html

For ex, under Windows thumbs cannot be yet extracted and extra video codec
needs to be installed to render preview.

So, please test on your OSX. Thanks in advance

I tested here using samples from http://www.sample-videos.com/

Mp4 and 3GP preview work fine. Other format, no.

I'm sure that it's a missing codec problem installed on the system and used by
Qt5Multimedia (same problem than under Windows).

The preview doesn't work at all (idem than Windows probably).

I confirm from video preview : the problem is the same than under Windows :

The video Monitor feature error message come from QT5::Multimedia. This feature
is not yet implemented in Qt under OSX.

To be able to play more video types, you need to install a video codec pack as
under Windows. Typically this one :

Caulier, sorry to reply so late.

The link above redirects to Perian, which is a software that extended Quicktime
7 to work with other codecs. But Quicktime 7 has long ago been retired and
QuickTime X (used in macOS >= 10.8 I think) is no longer extensible like that.
So the link doesn't really help, sorry. If Digikam5 relies on Qt5-Multimedia
and Qt5/Mac relies on Quicktime, Digikam might never be able to show or play
other codecs like AVI files ...

I just tested it anyway: Viewing mp4 and MJPEG-AVI files (from a digital
camera) works fine on my OS X 10.11.5 machine (no thumbnails are created
though, just as the README said). Great work, thank you! For the thumbnails I
get this error on the console:

digikam.metaengine: Cannot load metadata from file   (Error # 11 :
/Users/Jens/Pictures/20141106_172159.mp4: The file contains data of an unknown

Also, the above digikam package crashed on quit on my machine. I'll try again
and open another bug report for the crash if it is repeatable.

digiKam 5.4.0 bundles will use QtAV framework instead Qt5Multimedia to thumb
and play video. The Slideshow tool will also support video as well.

QtAV use ffmpeg codecs. It's multi-platform and will always available in
OSX, Windows and Linux bundles that digiKam team provide.

For Linux packagers, you will need to turn on video support at compilation time
and solve QtAV dependencies...

This is great news, thank you! Unfortunately the MacOS package does not start.
There seem to be unresolved symbols. The Linux x86-64 appimage works fine
though.

Unfortunately I cannot post the whole backtrace here because bugs.kde.org
thinks it is spam.

Here Macbook pro 2016 with OSX 10.12.2. And it work fine here.

I currently recompile all the bundle under Yosemite with a backward
compatibility with OSX 10.8. I will upload the new bundle this evening. Be
patient, it take 4 hours to build...

Works fine! Thank you! Plus, movies and movie thumbnails also work now under
macOS. (tested with .mp4 H264 and .AVI MJPEG files)

Great work!

... however, I do not have any sound (appimage, Linux Ubuntu 16.04, 5.4.0
@22b397e1b). Any ideas?

Sound is fine on Mac OS X.
