> Hi all,

> Exiv2 video support exists, but it's completely bugous and crash digiKam

> The way to use ffmpeg as new dependency do not increase the application
> complexity. The dependencies puzzle still the same as use use already QtAV
> to play video and this one use ffmpeg in background. So digiKam depends
> already of ffmpeg since 5.4.0 release.
> The idea to support properly video metadata is to be able to manage video
> medias as images. The database must be able to search video items based of
> video properties, taken from metadata. The search engine is already ready
> since a while, by the scan engine used to populate the database is not
> suitable as video support in Exiv2 is so far un-finalized (in video file
> parser).
> Else, Exiv2 is well implemented to support video metadata tags, as all XMP
> namespace implemented by myself few years ago. So if we have a different
> parser to fill XMP tags from video, the problem will be solved.
> And it's done with current implementation from next 6.0.0 branch. FFMPeg is

> model,
> dates,
> duration,
> codecs,
> keywords,
> rating,
> GPS,
> etc... (and more)
> i tested with my personal video collection, mostly based on MOV file
> generated with Apple devices (iphone, ipad) and Software (iMovies, Final
> cut pro). But i need more video samples :
> - Video taken from Android device,
> - Video taken from digital camera,
> - Video generated from software (with properties set as Keywords, rating,
> copyright, etc.)
> If you have samples to share, please use Internet Cloud repository. If you
> know place on Internet with video samples to share, to hesitate to share in
> this room.
> Thanks in advance for your help.
