Michael Weghorn 79644440bd tdf#145735 qt avmedia: Return video resolution for preferred win size 
In `QtPlayer::getPreferredPlayerWindowSize`, retrieve the
video resolution from the meta data and return that for the
preferred window size if available, instead of always returning
an empty rect.

For the sample presentation referenced in tdf#145735,
the size retrieved this way also matches what
`GtkPlayer::getPreferredPlayerWindowSize` returns
(720x400).

As mentioned in

        tdf#145735 avmedia qt: Use QtMultimedia for Qt 6 media playback

, the behaviour without this was:

> * In non-presentation mode, the placeholder
>   shown until the video gets started using the controls
>   in the sidebar is just an "audio icon", not a frame
>   from the actual video. (This might be related to the
>   fact that `QtPlayer::createFrameGrabber` currently
>   returns an empty reference.)

With this in place, the placeholder is now a different
icon, a "video icon" (but still not a frame from the actual
video).

Audio / video Media Implementation.

Provides per-platform implementations of multimedia functionality. Currently no stream API is provided, only a URI based one, so streaming has to be wrapped around it via temp files.

Also provides (in source/framework/mediacontrol.cxx) an implementation of the graphical media playback control that appears in the toolbar / mediaobject bar when media is selected under the .uno:AVMediaToolBox item.

avmedia / gstreamer

The avmedia component is implementation of manager service defined in offapi/com/sun/star/media/. Radek has added implementation based on gstreamer so that we can add audio and video files into impress presentation on Linux with gstreamer.

The implementation is pretty straightforward, sometimes it has problems when gstreamer installation is incomplete.

In the beginning the media files were not embedded, Thorsten added support for that later.

Future Works

it might be worthwhile to revamp the avmedia UI.
