How do I always select SDH English subs if found but fall back to regular English if SDH is not found?

[Pentaphon]

@CogentRedTester or anybody else out there, I have a deaf friend who prefers SDH English subs but if he can't get them, would like to always fall back to regular English subs. How would he config this?

English SDH subs are hard-of-hearing subs like "Text # 2" in the following mediainfo:

Let's say a file only has the English subs but not SDH. If you whitelist to always select SDH, that works, but if SDH is not there, subs are disabled instead of having the regular English sub selected. Can conditions help me?

Just add a second english entry to the json file without a whitelist.

[CogentRedTester]

As you said in what I assume was a deleted comment you had invalid JSON syntax.

[CogentRedTester]

So is it fixed like you said in the deleted comment?

No I double checked just to be sure and it wasn't fixed (so I deleted the comment) in the file you see in the log so please look at it, sorry.

In the log file you posted the script crashed due to invalid JSON formatting. If you're using the exact JSON that you posted above then I'd suggest you add the missing comma after the first "slang": "eng?" and remove the trailing comma after the second "slang": "eng?".

Ah, so I did actually post the wrong syntax here. Thanks for the correction. It works now. Thanks for your help. I'll delete my log now for privacy reasons but I'll post the updated json so other people can copy the correct syntax if they have my same issue.
