NaN index of audio source

[jedenastka]

For some reason, the index of any audio sources I have is shown as NaN, making it so I can't select it.

Could you run Mon2Cam with the -v (verbose) flag, and post the results?

Hmm weird, for some reason the command's output is translated to your language. I'm not sure how we can disable this.

[botiapa]

Could you run pactl list sink-inputs but with the LANG environment variable set to en_US.UTF8?

Edit: Nevermind, it seems to disrespect this variable it seems.

[ShayBox]

LANG=C pactl is usually the lang most systems have generated

[jedenastka]

LANG= worked, as usual:

Oh! I found the problem. It's actually the language, not anything else. I ran LANG= ~/programy/deno run -A -r -q --unstable mod.ts -v -r 1920:1080 -b -s and it works as intended!

Maybe the code has trouble parsing non-ASCII characters (we have quite a lot of them in Polish - ęóąśłżźćń) or non-English languages at all?

I noticed that the output of pactl in my native language does indeed give the right Unicode characters and not �:

So the problem isn't in pactl itself.

[botiapa]

Yeah, the program can only parse the english version. Glad it worked out.

TODO: Add LANG= before commands, so this doesn't happen.

[ShayBox]

Just Deno.env.set("LANG", ""); might work for the entire program, testing needs to be done

[ShayBox]

I'll setup an arch vm with non english lang to reproduce and test this

[ShayBox]

I pushed a change that should fix non English lang systems
