Ripping subtitles from medici.tv as .srt

[pedrothelion]

Hello

I downloaded a documentary from medici.tv with youtube-dl GUI and it worked well.

Now I'm trying to rip subtitles from the same docu (they are splitted into many .webvtt segments) using Firefox and activate developer mode to inspect element. Then head to Network tab to find and search for: 'subtitles' or 'm3u8'.

What I get is a file of about 70 KB with .mp4 container.
I opened the file with notepad and this is the (partial) content:

WEBVTT

00:00:00.000 --> 00:00:04.280

then I renamed the file as .vtt and converted it as .srt with Subtitle Edit.

The result does not seem to be a correct .srt file. In fact, combined with video, timestamps are busted, completely useless and out of sync.

Am I wrong in converting from .vtt to .srt or should I look for a different key with the developer tool?

[LZAA]

Url?

[sysanin]

LZAA это то же самое, что и здесь

[pedrothelion]

Url?

not resolved

[sneaker]

I guess this should be simple to fix using regular expressions.
Find:

^(WEBVTT|X-TIMESTAMP-MAP.*)(\r\n|\r|\n)

and replace by nothing.
Editors like Notepad++ and SublimeText offer such Search and Replace (All) feature with regex.

[pedrothelion]

But timing problem remains. It does not seem regular as expression...

[sneaker]

Sorry, I didn't see the timing problem. Indeed, that seems to be the complicated part.

I'm wondering if it is even possible to reconstruct the correct timings from just the info you posted.
Does the following fit the video?

1
00:00:00.000 --> 00:00:04.280
Le piano est un instrument

2
00:00:26.840 --> 00:00:30.279

Nope... it should be like this:

WEBVTT

1
00:00:22.020 --> 00:00:27.004
The piano is finally
a rather neutral instrument.

2
00:00:27.008 --> 00:00:31.018
But it has a limitless ability
to transform itself.

3
00:00:31.022 --> 00:00:35.005
Thus, it can become

4
00:00:37.003 --> 00:00:39.003
a singing instrument...

5
00:00:47.017 --> 00:00:50.001
To see how this instrument

6
00:00:50.005 --> 00:00:53.018
actually reacts,

7
00:00:53.022 --> 00:00:58.013
and yields
to whatever you want to do,

8
00:00:59.010 --> 00:01:02.001
to what you are after,

9
00:01:02.005 --> 00:01:05.012
is something quite extraordinary.

10
00:01:05.016 --> 00:01:09.005
This is why I still am,

11
00:01:09.009 --> 00:01:11.003
so happy to be a pianist.

I can provide access if needed.

[sneaker]

I probably won't be able to help. I cannot even manually get from the quotes in post #1 to the file from post #8, let alone in an automated way. I think it's not possible but you need more data.

Thanks for your reply. I finally succeeded with Allavsoft
I will also try with URL Snooper.

I have the exact same problem as the OP.

I used FFMPEG to download subs from the same web site with the following command:

ffmpeg -i "https://sdn-global-streaming-cache-3qsdn.akamaized.net/stream/9378/files/18/12/1068412/9378-HWQKVTXrYyxwncZq.ism/9378-HWQKVTXrYyxwncZq-textstream_eng=1000.m3u8?mime=mp4&source=html5" subs.srt

The result is identical to youtube-dl and so it should be because youtube-dl uses FFMPEG to download and convert subs.

I downloaded one of the VTT segments from the above playlist:

WEBVTT
X-TIMESTAMP-MAP=MPEGTS:43875090,LOCAL:00:00:00.000

5
00:00:00.000 --> 00:00:02.791
What do you think
of her over there?

It appears that in a segmented VTT the timestamp is indicated by the MPEGTS value, which is offset by 1 second (90000). The correct start time (in seconds) could therefore be calculated by dividing the MPEG-TS by 90000, less one. FFMPEG/youtube-dl merely copies and pastes the local time, which in a segmented WebVTT is always zero.

Hello paralucent,
Make sure it's right for you, because I'm not sure.
check both.

Thank you so much marcelo_bor! The first one, subtitle A, was perfect!

How did you do it?

Thank you so much marcelo_bor! The first one, subtitle A, was perfect!

How did you do it?

so i used the m3u8x program.
here is the link> https://www.videohelp.com/software/m3u8x
caption b is 10 seconds late then.

done.

[Paralucent]

Thanks for the info. I started to install m3u8x a few days ago but a Windows Security Warning box appeared saying the certificate is from "DO_NOT_TRUST_FiddlerRoot". Did you get the same message?

It definitely didn't come to me.
you don't need to install anything, just extract the program to a folder and use it remembering that it is portable.
if you feel safe, go ahead on the program or search for information on 'DO_NOT_TRUST_FiddlerRoot' on google.

[Paralucent]

Thanks got it working.

If I paste the m3u8 subtitles URL in the 'Quality URL box' and then click 'Download' I don't get any messages about certificates. In order to obtain correctly synched subs I found I needed to select 'time according to EXTINF'. Thanks again for your help, marcelo_bor.

[winiehappy]

As for as my test, Allavsoft can download both videos and subtitles from medici tv. Simply copy and paste the medici tv video link to Allavsoft and click Download button, it will download both subtitles and videos into the Download folder.

[doctorm]

Same problem with another site. When I use m3u8x I get a folder of 141 en.m3u8_0000000000.vtt files containing text like: WEBVTT
X-TIMESTAMP-MAP=MPEGTS:126000,LOCAL:00:00:00.000

I'm sure I"m doing something wrong. m3u8x is kind of hard to understand though.

I run m3u8x. Paste the subtitle playlist into the box that says "Quality URL", check 'This Subtitle' and "One...One", and 'Download'.
A box opens, I click 'Time according to "EXTINF" and 'Start download'.

Am I missing something? I can get the subtitles complete and merged with ffmpeg, but it's full of garbage and has timing errors like mentioned above.

[tamagoyaki]

that m3u8x download box when you finish downloading all parts, click 'Combine' button on the top
Then it should build a merged srt for you

[ploxer]

there's disney+ addon on greasy fork that act like this so maybe modify ?

[doctorm]

that m3u8x download box when you finish downloading all parts, click 'Combine' button on the top
Then it should build a merged srt for you

I don't see a combine button. Also, I think there is an issue with there being commercial breaks and that the subtitle count restarts after each one. As a result m3u8x assumes it already download all segment by the first break.
I don't think it's the right tool.

Do I run into site rule issues if I mention what streaming site I'm looking at?

Edit: It looks like there is an ffmpeg patch for this that has never been added. Is there a way to institute that myself? https://gist.github.com/SebiderSushi/bdf8d46d5501f7085d0b27d8a19eb12c
