Next digiKam 5.4.0 will support de facto video format through QtAV framework,
without to install extra video codec. We remove Qt5::Multimedia dependency in
digiKam.

Committed on 11/12/2016 at 21:09.
Pushed by cgilles into branch 'master'.

digiKam port to QtAV/ffmpeg instead Qt5Multimedia : add video support into
Slideshow.

TODO:

- handle video rotation flag with new Exiv2 0.26 to autorotate media in player.
- port video thumbnailer to QtAV.
- remove Qt5Multimedia dependency.

For later:

- port old videoslideshow tool to QtAv.

It's diffcult to judge, but at least we can give a clear state:

1/ Qt5::Multimedia framework do not give the same results on OSX and Windows
compared to Linux.
2/ Qt5::Multimedia framework under Linux use GStreamer codec in background
under Linux, which is a huge pain for end users. GStreamer is insoluble puzzle
with a lots of run-time dependencies. I tried to bundle it in AppImage for
5.3.0. Result, i lost one week only on this topic. This do not work !
3/ Qt5::Multimedia framework under OSX and Windows require extra codec. Why???
4/ Possible solution is to use ffmpeg backend + a Qt5 interface. Some project
already exist but are complex or not finalized or use OpenGL for video. OPenGL
is another pain, especialy uner Linux. So not at all...
5/ Another solution is OpenCV. But i'm not yet sure about the low level backend
used to decode video. OpenCV is another big puzzle, complex to solve.
6/ Write a Qt5::framework plugin to use ffmpeg. I don't found something
somewhere yet on the web... This will be my preferred way, but it's require
investigation and time.

Alternative to process video frame extraction can be done with OpenCV library,
also used by digiKam :

It's not a bug, it's a limitation of Qt5::Multimedia under OSX and Windows,
which cannot do extract video frames.
