Subtitles composer issue

Hi,
I have an openSUSE Leap 15.2. I haven’t use the Subtitles compose for years. And I open it today.
(Last time I used it, probably, was with the pre 15.x Leap versions).

My main issue is that I don’t hear sound from the videos and the video screen is black!
I can improve the situation with some of the back ends (like for example to have a video with the MPV player (what is that???) or have sound with GStream and alsa, but never both of them!

Any idea how t fix this?

I will answer my own question:
I downloaded the package from home_maxrd2 repository and now it’s OK.

Which Subtitle(s)?

That the standard GNOME package didn’t pass the openQA on the Open Build Service (OBS), is surprising …
Ditto the GTK+3 package …

[HR][/HR]As far as subtitle editing is concerned, there’s this comparison – <gThumb: An AVIF Image Viewer for Linux System.
