yt-dlp switching off embedded subtitles

[samozaparola]

Is there a way when embedding subtitles to prevent them from starting automatically upon video playback through yt-dlp options?

[ElCap]

sounds like more of a player issue than yt-dlp.
what player are you using?
have you tried other players like vlc, potplayer, etc?
do they have the same issue?
do you have a shortened video that you can upload for people to test with?

Thank you, ElCap!
You may be right... I use mostly PotPlayer, tried also VLC and PowerDVD (the latter won't show the embedded subtitles, I have no idea why).
Using the MediaInfo tool today, this is the result I got about a downloaded video:

Text
ID : 3
Format : D_WEBVTT/SUBTITLES
Codec ID : D_WEBVTT/SUBTITLES
Duration : 55 min 43 s
Title : English / English
Language : English
Default : Yes
Forced : No

I checked another video, a movie, ripped from a CD I suppose, and both the Default and Forced flags were set to No.

Default : No
Forced : No

So is it possible to achieve a result like this with yt-dlp?

The only info (setting a default subtitles track) I found was this:

(https://github.com/yt-dlp/yt-dlp/issues/3450)
--ppa "VideoRemuxer: -disposition:0 default"

But I have no idea what the options and the parameters mean.

ffmpeg has a fine documentation on their site: https://ffmpeg.org/ffmpeg.html - search for the "-disposition" argument.

yt-dlp can reach these arguments through to ffmpeg with the --ppa option.
--ppa "EmbedSubtitle:-disposition:s:0 0" should remove the "default" flag from the embedded subtitle, and thus preventing it to show up on video display by default.

[All put together from the issue you've linked to, btw.]

Thank you, very much Obo!
However, with the code you provided the result is unchanged:

Default : Yes
Forced : No

Does the options order matter? The code I use is:

.\yt-dlp -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best" -i --merge-output-format mkv -o "E:/%(uploader)s/%(playlist)s/%(playlist_index)s. %(title)s [%(id)s].%(ext)s" --embed-metadata --embed-thumbnail --embed-chapters --write-subs --write-auto-subs --embed-subs --ppa "EmbedSubtitle:-disposition:s:0 0" --compat-options no-keep-subs https://www.youtube.com/playlist?list=PLRQJ5GpQaktH0wtce-s4cHEar_YwKVvjq

..

'--ppa "VideoRemuxer: -disposition:s:0 default"'

[samozaparola]

Thank you LZAA, but it doesn't work either. Is there any more detailed documentation about this? According to https://ffmpeg.org/ffmpeg.html the code has to be:

ffmpeg -i in.mkv -c copy -disposition:s:0 0

But it doesn't work either way.

I seem to recall that the mp4 container requires a default track but it won't automatically play unless your media player is set up to do that.
