I think it is a must have option since digikam is DAM tool and all cameras are capable of recording videos nowadays.<br></div><br>Per this webpage: <a href="http://dev.exiv2.org/projects/exiv2/wiki/Supported_video_formats" target="_blank">http://dev.exiv2.org/projects/<wbr>exiv2/wiki/Supported_video_<wbr>formats</a> Exiv2 can read but can't write. They also say "Write metadata support for RIFF, Matroska and partial metadata
write support for Quicktime video formats will be included in subsequent
releases."<br></div></div></div></div></div></div></div></div></blockquote><div><br></div><div>yes, progress to support video metadata is too slow. I already reported this wish in Exiv2 team, but the state is to delay to 0.27 some improvements in this way.</div><div><br></div><div>At least we need 0.26, which is not yet released since more than one year. This one fix more than 200 bugs, especially to stabilize video reading metadata. </div><div><br></div><div>Note that current Exiv2 0.26-svn is included into digiKam bundles.</div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div><div><div><div><br></div>But there might be another tools out there that are already capable of reading/writing video files' metadata, e.g. exiftool ,ffmpeg, etc.<br></div></div></div></div></div></div></div></blockquote><div><br></div><div>exiftool is perl tool. So no way to use it as well in C++.</div><div><br></div><div>ffmpeg is very interesting and as we use QtAV framework which is a Qt5 based interface to ffmpeg, this is the right alternative to, at least provide a better support of video metadata in read mode. </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div><div><div><br></div>I am particularly interested in reading/writing the following tags:<br></div>- Creation date<br></div>- Rating<br></div>- Keywords (tags)<br></div>- People (if possible)<br></div>- Geolocation (exiftool can do that see: <a href="http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=5977.0" target="_blank">http://u88.n24.queensu.ca/<wbr>exiftool/forum/index.php?<wbr>topic=5977.0</a> )<br><div><div><div><div><br></div><div>Right now digikam seems to be unable reading/writing metadata from/to video files.<br></div></div></div></div></div></blockquote><div><br></div><div>if you use digiKam based on Exiv2 0.25, yes. Bundle can be a better way to start, it's not perfect, but better...</div><div><br></div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div><br></div><div>Please let the group know your thoughts.<br></div><div><div><div><div><div><div><div><br clear="all"></div></div></div></div></div></div></div></div></div></div></div></blockquote><div><br></div><div>So, contacting QtAV team to introduce a metadata interface for video file is the way to go. QtAV is hosted in GitHub. Please report this wish to QtAV bug tracking. </div><div><br></div><div>Thanks in advance</div><div><br></div><div>Gilles Caulier</div></div></div></div>
