Batch download does not include subtitles

[venkat2305]

Describe the bug The video meta data shows it has a sub file but when selected in the player there are no subtitles

To Reproduce Steps to reproduce the behavior: Keep the output format to auto and enable subtitle Download this video

Expected behavior When selected, we should see subtitles on the player

Screenshots

Additional info (please complete the following information):

• OS: [ Windows 10]
• Application version [2.4.8]
• Application type [installer]

Additional context The problem is that when the we enable subtitle option, the output format it not changing from MP4 and as we know we cannot pass-through subtitles files to MP4.

Fix: if the user enables subtitle option , change the output format

[venkat2305]

update: I forced the format to MKV. Now there's no subtitle in the video.

Reproducing now, I enabled subtitles like this:

And clicked on download.

After the download the subtitles are in the same folder:

I can select the subtitle file in the video player:

But you are asking if we can embed subtitles into the video file itself? We would have to check if yt-dlp supports that

[StefanLobbenmeier]

Those are the options we can pass for subtitles: https://github.com/yt-dlp/yt-dlp#subtitle-options

At the moment open video downloader is passing those options:

--write-sub
--write-auto-sub
--embed-subs
--sub-lang [all the subLanguages separated by comma]

Also tried with another video player (mpv.io), where it somehow finds an additional "en" and "unknown" subtitle track in addition to the .vtt files.

It keeps showing those 2 even when the .vtt files are no longer in the same folder. So I am assuming this actually worked on my machine. Can you also try with that video player?

I enabled subtitles in a different way. please check this video. there are no subtitles on the video.

I enabled subtitles option but didn't select which subtitles to select and there is no default selection. I thought subtitles are embeded in the video. does this make sense?

I tried mpv player. and it couldn't show the subtitles aswell. can you please look into this? also, when possible , can you please add an option to embed subtitles?

Suggestions:

1. there should be a default selection when the user enables subtitle option. right now, I think it's not selecting anything.
2. an option to enable subtitles by default in the settings and add our preferred languages for subtitles.
3. an option to embed subtitles into the video. its less clunky and we can move the video file around without having to worry about the subtitle files.

I see, I was not even aware of that button down there, haha 😄

Will leave this in the backlog for now since that is a lot more work than just a simple bugfix.

[StefanLobbenmeier]

Can you just confirm that subtitles work on your machine via this subtitles button?

[venkat2305]

I selected three languages with that option, and three subtitles' files were downloaded. but there are 7 tracks of subtitles in the video.

in this image track 1,2,3 are the selected subtitles. I think track 4 has chapter information. please check why there are other subitiles files and they don't have anything in them.

should I make a new issue for this feature request.

[StefanLobbenmeier]

No need to create a separate issue, but for now I am not going to prioritize this, since I never use the download method you showed in your video. Feel free to implement this yourself and add a PR though.

+1 to this. I'm planning on archiving some playlists and I'd much rather not have to select subtitles on every video.

[shanedk]

+1 as well. It's annoying having to go through long playlists and set this one by one.
