No. To deal with video file metadata is delegate to ffmpeg. Reading with
this backend work as expected, writting is very very limited. I use this
way in my office with a video recorder and MP4 files and it's so far
perfect. Only MP4 file can be patch in metadata with ffmpeg, as i seen.

The second and historical way will be to use Exiv2. Unfortunatly, video
support still experimental since many years, and is very instable. As i
seen in Exiv2 forum, video support will be removed for 1.0 version.

XMP is the only way to tag read only file. It's generic and standardized.
You must report this problem to Kodi and Plex team to add XMP sidecar
support. Exiv2 can read this meta files as well without any extra rule from
client applications. As both Kodi and Plex are written in C/C++, it's
possible.

Not sure that write videos tags in videos files with digikam will be the

Why this application do NOT use standard, where metadata are well
standardized ??? Why to comlexify the game ? Why always to ask to fix
digiKam in this kind of situation.

Do you have any recommandations or do you know workaround ?

ExifTool, written in Perl can do it, but i never experimented well to see
if all video file mime type are supported.

It must be.
