> Hi all,
>>
>> This week, i solved a main problem with video support in digiKam with next
>> 6.0.0.
>>
>> Exiv2 video support exists, but it's completely bugous and crash digiKam
>> quickly. This problem exists since many year now, and as nobody is
>> motivated to fix Exiv2 video code, i used a different way to support video
>> metadata : ffmpeg.

>>
>> 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
>> able to extract most important video properties as :
>>
>> make
>> 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.
