I would like to use Subtitle Editor to add some subtitles to an AVI file. When I try to open the video in Subtitle Editor I get the error:

GStreamer plugins missing. The playback of this movie requires the following decoders which are not installed: ITU H.264 (High 4:4:4Profile) decoder

the following are already installed:

  • GStreamer gstreamer-ffmpeg
  • gstreamer-plugin-crystalhd
  • gstreamer-plugins-bad
  • gstreamer-plugins-bad-free
  • gstreamer-plugins-bad-free-extras

  • rpmfusion-free-appstream-data
  • rpmfusion-free-release
  • rpmfusion-nonfree-appstream-data
  • rpmfusion-nonfree-release

I can't figure out if I need to install something more or delete something. Any help would be appreciated.

I'm running Fedora26, with Plasma/KDE desktop.

Are you able to open that file in a different program, such as Banshee? If so, you already have the needed codec and the question becomes why this program can't open the file. If not, we can look into the codecs and find out why you're missing the one you need.

Banshee doesn't want to run under KDE.

I'm able to get sound from the video in the GNOME version of Subtitle Editor and KMPlayer but no video. Totem gives me the same error as the KDE version of Subtitle Editor (The playback of this movie requires the following decoders which are not installed: ITU H.264 (High 4:4:4Profile) decoder). When I clicked to "find software" Discover came up with a blank window and sound started playing.

I get both sound and video with VLC Media Player.

OK, if you can play the file with VLC, you have the proper codec installed. Now the question becomes why Totem and your subtitle editor can't open it. BTW, what is the name of that program, so that I can install it and try to duplicate your issue under Xfce.

The name of the subtitle editor - very creatively - is Subtitle Editor. I found it in Apper. It's the one with the description of being a GTK+2 tool to edit subtitles for GNU/Linux/*BSD. It lists the version as 0.53.0-2.fc26

That may be how Apper describes it, but it's not the program's name. And, as Apper is a KDE program and I use Xfce, I don't have it installed. Sorry, but that's not enough for me to go on.
