<p>Is there a way to add a launcher of external bash/python scripts
to digiKam?</p>
<p>Right now I am working on a bash script that compresses video
files using ffmpeg and moving metadata atoms from the original to
the output using bento4 (apparently some metadata gets lost during
conversion even though there is an option in ffmpeg to preserve
it). <br>
</p>
<p>After that I want to write a script to read video file creation
date (exiftool or mediainfo or both) and overwrite the wrong date
that digiKam writes to XMP sidecar file.</p>
<p>Next step will be reading tags (keywords) and people tags from
XMP sidecar files and write them to video files using exiftool
probably (this one should be easy to accomplish).</p>
<p>Next step will be a script to read GPS location for video files
from XMP sidecar and write it to video files using bento4.</p>
<p>If I could call each script right from the context menu in
digiKam that would help a lot.<br>

<div>It was me who proposed to use bento4. I tried it and
it worked well to import metadata from a text file as an
atom to mp4.</div>
<div><br>
</div>
<div>I think treating images and videos the same way is
why exiv2 isn't working. For example, images would store
creation date as "Date created" while videos would have
it as "Date Encoded". Just an example.</div>

<div dir="ltr">yes. The problem is that metadata
abstraction use the same interface for image and
video. It's homogeneous. If we want to use another
frameworks for video only, this will increase the
complexity of DK code, so the probability of bugs.

<div>We have an entry in QtAV framework to have an
interface to handle metadata with ffmpeg, but we

<div dir="ltr">Hi,
<div><br>
</div>
<div>yes, i agree. this is not the first
time that Exiv2 team drop as well the
report. </div>
<div><br>
</div>
<div>I responded on Exiv2 bugzilla where
Robin Mills said that digiKam is badly
designed. Technically the crash is in
Exiv2 while parsing metadata. The
architecture is the same in digiKam
for image and video. We don't see any
dysfunction about images. I use it
everyday. For video support, Exiv2 has
a not stabilized code yet. This is the
problem.</div>
<div><br>
</div>
<div>The ultimate solution is to disable
video metadata IO with Exiv2 from
digiKam. I don't see no better way....</div>
