<br>
just wanted to get back on the question of the suitability of the C++ Interface for ExifTool for DigiKam. Perhaps you have found some time already to take a look at it?<br>

What tool is creating xmp sidecar files for the video files at<br>
the moment? Exiv2 ?<br>
<br>
<br>
yes<br>
<br>
<br>
<br>
But anyways, there has to be something else in the FOSS world<br>
that can handle the job.<br>
<br>
Video format is just too different from the image format so it<br>
is tough to find a tool that can handle both very well. Exiftool<br>
came pretty close to that but it still lacks of ability to write<br>
many of tags.<br>
<br>
<br>
Exiftool is perl based, not C++<br>
