So, for example, from file.mp4 digiKam will have to create file_out.mp4, then remove file.mp4 then rename file_out.mp4 to file.mp4. I think Gilles tested it and it slowed down the application a lot (too much).</div><div>Maybe one day someone will write a plugin for that. In that case only the users who want write to video files will install and activate the plugin. I am one of them too. So I might chip in into the development if I understand how the new plugin interface works.</div><div><br></div><div><br></div><div><br></div><div><br></div><div id="composer_signature"><div style="font-size:85%;color:#575757" dir="auto">Sent from my Samsung Galaxy smartphone.</div></div><div><br></div><div style="font-size:100%;color:#000000"><!-- originalMessage --><div>-------- Original message --------</div><div>From: John Bray <johnbray822@gmail.com> </div><div>Date: 2019-03-10 9:55 AM (GMT-07:00) </div><div>To: digikam-users@kde.org </div><div>Subject: [digiKam-users] Reading/writing Video metadata to Caption/Title </div><div><br></div></div>Would it be possible to extend the Metadata/Advanced configuration<br>options to read/write video, especially avi and mp4, metadata to<br>Captions/Captions or Title.<br><br>I currently use external scripts to do<br><br>exiftool -Title="title" file.mp4<br>mencoder oldfile.avi -oac pcm -ovc copy -info name="name" -info<br>subject="subject" -info comment="title" -o newfile.avi<br>ffmpeg -i oldfile.mp4 -metadata title="title" -metadata<br>comment="comment" newfile.mp4<br>ffmpeg -i oldfile.avi -metadata title="title" -metadata<br>comment="comment" newfile.avi<br><br>And I see that digkam 6.0.0 now supports ffmpeg, so it should be straightforward<br><br>Currently it seems that the Captions Caption/Title information seems<br>trapped inside Digikam's database, and is never read or written to<br>files.<br><br>Thanks<br><br>John<br></body></html>
