Inconsistent language flags

[lkiesow]

Given the subtitle configuration

[subtitles.languages]
"captions/vtt+de" = "Deutsch"
"captions/vtt+en" = "English"

you end up with a view like this:

• Where does the German flag come from?
• Why is there none for English?
• Can we make this somewhat consistent?

The code at fault is this function here:

opencast-editor/src/main/SubtitleSelect.tsx

Line 66 in 1a63c95

const parseCountryCode = (parseString: string) => {

Where does the German flag come from?

It's unicode!

Why is there none for English?

The function extracts a substring from the subflavor in the vague hope that it's a valid unicode flag. "en" is not a valid unicode flag.

Can we make this somewhat consistent?

Probably not (without a lot of effort)! There's no standard way of telling which language a vtt file belongs to (or no language, or multiple languages...), so we would have to come up with one.

[lkiesow]

If it's only Unicode icons anyway, I've got an idea.
Why not let users configure them as well?
Something like this:

[subtitles.languages]
"captions/vtt+de" = "Deutsch"
"captions/vtt+en" = "English"

[subtitles.icons]
"captions/vtt+de" = "🇩🇪"
"captions/vtt+en" = "🇺🇸"

What do you think?

[Arnei]

Not a bad idea? I guess you can trust a person who sets up the config to set reasonable values for the icons.

[lkiesow]

Well… if we can't trust the admin, we have already lost anyway ;-P

[Arnei]

Although if we implement #826, your suggestion would not work for some subtitles, as we would then display subtitles that are not set in the config, right?

[lkiesow]

That's true. But that's true already, since those wouldn't necessary even have a +lang as part of the flavor. It's also more that I couldn't access a subtitle I knew was in the system and I wouldn't expect that to be common.
