Video players and subtitles files

[Bret Busby]

Hello.

Do any of the video players that are available for Ubuntu, support 
subtitles files with the .en.dfxp extension?

I have tried downloading and playing a video file with the above 
extension, using the yt-dlp switch --write-subs and the subtitles file 
appears to have downloaded okay.

However, in trying to view the video using the following video players, 
I cannot get the subtitles to be displayed.

Celluloid
mpv
SMPlayer
vlc
Media Player

Those video players appear to not support the above subtitles file 
extension.

When I download fro youtube, using yt-dlp --write-auto-subs, the file 
extension is .en.vtt, which, when using the above video players, is 
automatically loaded and displayed in the playing of the video, except 
for the Media Player, which does not apply the subtitles file.

So, I am wondering whether one of the video players that is available 
for Ubuntu, supports subtitles files with the .en.dfxp extension?

Thank you in anticipation.
