How to get subs from NBC?

[m0ck]

In the majority of cases, yt-dlp can get subtitles from NBC, but sometimes there are videos that make yt-dlp fail. I was hoping there might be a manual way to get subtitles in such cases. I tried filtering and looking for VTT, XML, etc., but with no success.

Can anyone help?

Here are two examples of videos where yt-dlp fails:

Have you tried downloading the videos? Sometimes, they can't be found as external, neither as separate tracks in the manifest, but as closed captions in the file. You can then use ffmpeg to rip them from the video files.

But how exactly?
CCExtractor extracks subs from a video file, right?
I downloaded a video from NBC but it doesn't have subtitles inside so CCExtractor won't extract them. What am I doing wrong?

This is my downloaded video: https://gofile.io/d/ua5cI5

ffmpeg -f lavfi -i movie=62.mp4[out+subcc] -map 0:1 -c:s text -y "output.srt"

Thanks so much. What if there are two subtitles (languages) in a video?

[2nHxWW6GkN1l916N3ayz8HQoi]

That's actually a good question. Do you have a video like that? I'd like to test ffmpeg to see how it should be used in that case

This video should have two subtitle tracks (English and Spanish). https://gofile.io/d/FtRwtK

That's a tricky one. I don't have the answer for it. The ffmpeg command manages to get the spanish subtitle, but the english one no idea how to get it. I think it's better if you use ccextractor like @iamghost mentioned.

Just for the sake of learning ffmpeg better, if an expert knows how, please let me know.

mkvinfo + mkvextract could do the job ?
I downloaded the video and opened in VLC, no subs are detected, weird.

But ccextractor doesnt work for me at all. it just creates empty txt file. I used portable version with default settings.

ccextractor should work. Maybe someone that knows the tool can help you.

Meanwhile there's this ffmpeg gui alternative. Apparently it works for both languages

You load the mp4, click main -> extract 608 and type in the small box 0 or 1. 0 for spa, 1 for eng. You can then use subtitle edit to get rid of any formatting

1_S_0_extracted.srt
1_S_1_extracted.srt

Now I'm just curious what's the ffmpeg command used in background. After all, it's just a GUI

Maybe (not working all the time + need to be fast), you can try grabbing the command used :

ps -eaf | grep ffmpeg

install the firefox browser addon called Netmon - https://addons.mozilla.org/en-US/firefox/addon/netmon/
once installed, play the video and search for subtitle you'll get this - https://vod-lf-oneapp2-prd.akamaized.net/prod/telemundo/bKd/jnk/4348004/1683192341244-...Narrative=true

which i guess is both English & Spanish subtitles ??

[iamghost]

dont run gui just go to ccextractor folder run cmd from this folder
-1 is track 1 spanish
-2 is track 2 english

ccextractor.exe  --gui_mode_reports  -2 -out=srt -bom -latin1 "path video.mp4"

To extract the EIA-608 closed captions with ffmpeg in Spanish:

ffmpeg -f lavfi -data_field 0 -i "movie=1.mp4[out+subcc]" -map 0:1 output-es.srt

To extract the second track of closed captions in English:

ffmpeg -f lavfi -data_field 1 -i "movie=1.mp4[out+subcc]" -map 0:1 output-en.srt

To extract the second track of closed captions in English:

ffmpeg -f lavfi -data_field 1 -i "movie=1.mp4[out+subcc]" -map 0:1 output-en.srt

Marvelous So it's all about -data_field.

Thank you all for your help.
One more question. How do I know if a video has EIA-608 subtitles?
They're are not available in video players, media info doesn't show information about them as well.
