How to find link to video file from URL

[Pavel_47]

Tell the player to show subs.

There is no subtitles embedded in the file. Tried on 2 machines - Windows and Ubuntu.
Probably one more option is needed.

[Pavel_47]

Most also write to file.

--embed-subs --write-sub --sub-langs "fr"

An other option is:

yt-dlp https://www.arte.tv/en/videos/101139-013-A/geo-reportage/ --write-sub

It work,make Geo Reportage [101139-013-A].en.vtt file.
Most video player find this .vtt(sub-title file) automatic as eg VLC.

The subtitles file (.vtt) is indeed created, but it fails to be embedded.

[Pavel_47]

Tried with multiple options trying to obtain output file with subtitles.
None of them worked.
Here is one case (I tried to convert vtt to srt; without converting it doesn't work either):

Output:

There is a problem embed WebVTT(.vtt) in mp4

Embed WebVTT? No, not supported in MP4

So can use FFmpeg look at link or search.

I found this command searching on the web. I thought that it should work as follows:

1. download video stream, audio stream and subtitles as .vtt
   
2. merge video and audio
   
3. convert subtiles .vtt to subtitles .srt
   
4. embed .srt in video-audio
   

So the command syntax is wrong or yt-dlp just doesn't allow you to do this ?
According to your advise to build the video with subtitles, one have to proceed with 2 streps:

1. download and merge audio & video and download subtitles .vtt using yt-dlp
   
2. use FFmpeg to embed .vtt in video
   

Correct ?

[Axel_Erfurt]

There is no need to download everything individually and then merge them together, yt-dlp does it all.

This works for me, VLC shows the subtitles.

This command create downloads .vtt file with subtitles.
Then you probably load the .vtt file while playing video in VLC. Correct ?
When I talking on "embedding" I mean you don't need load it using particular layer facilities.
BTW, probably not all players have option allowing to load subtitles.

[Axel_Erfurt]

It downloads 2 files,
Kamerun - Im Clando, dem Bus ins Exil [098294-000-A].mp4
Kamerun - Im Clando, dem Bus ins Exil [098294-000-A].de.vtt

Then I open the video in VLC and don't have to do anything extra.

Probably VLC search subtitle file by default ?
Did you try to rename .vtt ?
I tried with "Films and TV" player on Windows and default player on Ubuntu.
The subtitles aren't visible in both cases.

[Axel_Erfurt]

I have Linux Mint, mpv and celluloid (based on mpv) doesn't show subtitles even though you can select them.
Xplayer shows subtitles, but you have to load them.
