Using ffmpeg to dowload webvtt subtitles

[ecolek]

Hello,

I am trying to use ffmpeg to download subtitles from rts.ch server (without video or audio, just subtitles).

When I type the command

ffmpeg -i "https://rts-vod-amd.akamaized.net/ch/hls/11939634/c312a730-29df-37c0-bcd0-fcd591e964fb/index-f7.m3u8?aka_me_session_id=AAAAAAAAAADOQCRgAAAAAKaR 0iPtqt2nCH%2fsXwUI%2fXToRAS8en0tZY%2fka7HtqKbzD168 Fkbs8KCtxez739Dp2GN9eIEHVO9%2f"

then it gives me the result:

Stream #0:0: Subtitle: webvtt

At least one output file must be specified

when I add output.vtt at the end of the command it results in:

Which switches I should use with ffmpeg to properly download VTT or ideally SRT file?

Thanks in advance

Link expired, do you have a link to embedded video?

[jagabo]

By default ffmpeg doesn't mux subtitles. Try adding -map 0 (copy all streams) after specifying the source video. If that doesn't work thy adding a further -an and -vn (audio none, video none) too.

[Sviests]

Ok,i just tried downloading subs from a random video of that site and had no problems with FFMPEG, actually all you need to do is use a built in subtitle-codec argument:
-scodec (codec)

In this case this should work with no problem:

ffmpeg.exe -i "https://rts-vod-amd.../ww/hls/..m3u8" -scodec srt output_subs.srt

Hello again,

Once again, encountering issue when trying to download these subtitles:

ffmpeg -i "https://rts-vod-amd.akamaized.net/ch/hls/11997514/8f3c162a-6224-3cac-8f47-788ef9fd24dc/index-f7.m3u8" -scodec srt meurtres_en_berry_subs.srt

It just stops on segment #27 and produces a small SRT file with first lines of subtitles.

For grabbing the subtitles I use the M3U8 file provided it in my earlier email:

ffmpeg -i "https://rts-vod-amd.akamaized.net/ch/hls/11997514/8f3c162a-6224-3cac-8f47-788ef9fd24dc/index-f7.m3u8" -scodec srt meurtres_en_berry_subs.srt

try running your link through the firefox extension called "the stream detector" to grab the subtitles

[ecolek]

try running your link through the firefox extension called "the stream detector" to grab the subtitles

I use this extension to determine *.m3u8 components on actual page with the movie, but it doesn't have the capability to merge set of *.vtt files (here 710 segments) into one SRT file.

I was able to use FFMPEG for this purpose for previous movies at RTS, but here it breaks after collection of ~27 segments.

These specific subtitles are under DRM, unlike the previous ones. I guess it depends on the video you're trying to watch.

[ecolek]

Is this one also DRM protected? How do you recognize there is such protection in place?
https://www.rts.ch/play/tv/telefilm/video/meurtres-a-mulhouse?urn=urn:rts:video:12003885
At the website the movie is normally displayed with the subtitles without any limitations.

Attempt of extracting subtitles below just stops after 20 segments without any particular reason:
ffmpeg -i "https://rts-vod-amd.akamaized.net/ch/hls/12003885/cd6616a8-b1bc-39f8-b900-53ab628eba9e/index-f7.m3u8" -scodec srt subs.srt

Kinda they are,they have a line of:

#EXT-X-KEY:METHOD=AES-128,URI="https://rts-vod-amd.akamaized.net/ch/hls/12003885/cd6616a8-b1bc-39f8-b900-53ab628eba9e/serve.key?aka_me_session_id=AAAAAAAAAAA1YkFgAAAAAHOWOaz2ok%2ffFiM3Jv2qx4hagFzLMlw6Fh5XK5GYA438d%2fNqLEjeZYmz8S9x0b85YAST5FbTZokk"

There is probably a way to bypass it,but most likely with passing some headers/referers/user-agents or whatever.

how can i download this vtt correctly .. because when i opened on subtitle edit show encrypted Code .. please any help

I was able to use FFMPEG for this purpose for previous movies at RTS, but here it breaks after collection of ~27 segments.

Run ffmpeg again, the srt should have 1300 lines, last timestamp should be 01:29:39,840 --> 01:29:44,840. Run it 2-3 times (test1.srt, test2.srt) and see if you get the same result (~27 segments). Sometimes I get the (full) subtitles the the first time sometimes after the 2nd or 3rd try.

@jagabo @Sviests By default ffmpeg (using 4.2.3) will download the subtitles without the need to specify -scodec (codec) and/or map and/or -an -vn, just an output with the srt extension. Also ffmpeg will take care of decrypting the (encrypted) vtt files.

ffmpeg -i "https://URL/subtitle.m3u8?tokenifpresent" MyMovie.srt

BTW It also works for vtt output: ffmpeg -i "https://yourURL2sub.m3u8" test-1.vtt

I was trying to find a way to batch download them but I couldn't (jDownloader was giving a temporary error or something and downthemall can't batch download when 2 or more variables need to be changed).

Now it stopped working and gives complete gibberish.

I have no idea why I could opened them almost fine for a brief period of time and I'm sad that I couldn't find a way to dl them...

It probably boils down to the ffmpeg you are using.
After playing around with this the whole day, I finally managed to get the subtitles.
Use the same command and use the ffmpeg.exe that comes with Streamlink.
47.2 MB (49,592,832 bytes)
47.2 MB (49,594,368 bytes)

The downloaded subtitles seem to be different than the one LZAA provided.
LZAA subtitle has duplication.
This one doesn't.
But LZAA's version does not contain the long and unneeded dots.
This one does.

Now, a slightly off topic question.

How can a program like ffmpeg, open source, free, public etc etc. have the option to decrypt AES-128 without key?
It's basically destroying the protection the site is using.

[ecolek]

I am using Linux (Ubuntu 20.04.1) and streamlink doesn't come with any ffmpeg version embedded.

I have tried the newest ffmpeg packages (ffmpeg-4.4-i686-static or ffmpeg-git-20210611-i686-static) and effect is the same: WebVTT subtitle download cuts after 22nd segment.

Regarding decryption of subtitle, subjected file index-f7.m3u8 includes a key:

#EXT-X-KEY:METHOD=AES-128,URI="[....]"

Can you share your downloaded version of these subtitles?

Are you using VPN? I use Nord VPN.
I have no idea what's happening.
I tried again and I got the same result as you, stops after 50ish segment.
Then I tried another Swiss server, I think the same I used yesterday when I succeeded, it goes to the end but throws an error

Error when loading first segment 'https://rts-vod-amd.akamaized.net/ch/hls/12274261/d53cddc8-9375-38a4-b225-9016ba31ba02/segment-1-f7.vtt?aka_me_session_id=AAAAAAAAAAAbT9BgAAAAAAfyC+g3gaUxL00kIC1ukK3QbMVAF5Io9XaYvmptQK4fIpOPYphQF3RGgCwi3qWaEpjFyqWmGZ8d&aka_msn=1&aka_hls_version=3&aka_media_format_type=hls'

I have succeeded again with Swiss #308 on Nord VPN.
