Detect Closed Captions

Dazed

Hi,
I am trying to replicate a Tdarr plugin that detects closed captions and removes them if found. I am able to remove closed captions using FFMPEG Builder Nodes - Custom Parameters, and inputting -bsf:v "filter_units=remove_types=6". However, I am having difficulty creating a script that filters so that movies without closed captions are not processed.

I can see that the closed captions are listed within the stream info, but have not been able to call it from within a script

Is it possible to do what I am trying to do? My programming knowledge is minimal at best, any guidance would be appreciated.

Heres a function that should do it. Just make sure you set it to have 2 outputs

// execute FFmpeg to get the video info in a string
let ffmpeg = Flow.GetToolPath('ffmpeg');
let process = Flow.Execute({
	command: ffmpeg,
	argumentList: [
		'-i',
		Variables.file.FullName
	]
});

// check the output to see if the string Closed Captions appear anywhere
let hasClosedCaptions = process.standardOutput?.indexOf('Closed Captions') > 0;

// return output 1 if have closed captions, otherwise output 2
return hasClosedCaptions ? 1 : 2;
