Hi all,<br>
<br>
This week, i solved a main problem with video support in digiKam with next<br>
6.0.0.<br>
<br>
Exiv2 video support exists, but it's completely bugous and crash digiKam<br>
quickly. This problem exists since many year now, and as nobody is<br>
motivated to fix Exiv2 video code, i used a different way to support video<br>
metadata : ffmpeg.<br>
<br>
<a href="https://www.flickr.com/photos/digikam/39880716214/" rel="noreferrer" target="_blank">https://www.flickr.com/photos/<wbr>digikam/39880716214/</a><br>
<br>
The way to use ffmpeg as new dependency do not increase the application<br>
complexity. The dependencies puzzle still the same as use use already QtAV<br>
to play video and this one use ffmpeg in background. So digiKam depends<br>
already of ffmpeg since 5.4.0 release.<br>
<br>
The idea to support properly video metadata is to be able to manage video<br>
medias as images. The database must be able to search video items based of<br>
video properties, taken from metadata. The search engine is already ready<br>
since a while, by the scan engine used to populate the database is not<br>
suitable as video support in Exiv2 is so far un-finalized (in video file<br>
parser).<br>
<br>
Else, Exiv2 is well implemented to support video metadata tags, as all XMP<br>
namespace implemented by myself few years ago. So if we have a different<br>
parser to fill XMP tags from video, the problem will be solved.<br>
<br>
And it's done with current implementation from next 6.0.0 branch. FFMPeg is<br>
able to extract most important video properties as :<br>
<br>
make<br>
model,<br>
dates,<br>
duration,<br>
codecs,<br>
keywords,<br>
rating,<br>
GPS,<br>
etc... (and more)<br>
<br>
i tested with my personal video collection, mostly based on MOV file<br>
generated with Apple devices (iphone, ipad) and Software (iMovies, Final<br>
cut pro). But i need more video samples :<br>
<br>
- Video taken from Android device,<br>
- Video taken from digital camera,<br>
- Video generated from software (with properties set as Keywords, rating,<br>
copyright, etc.)<br>
<br>
If you have samples to share, please use Internet Cloud repository. If you<br>
know place on Internet with video samples to share, to hesitate to share in<br>
this room.<br>
<br>
Thanks in advance for your help.<br>
