[Features Request] Subtitles support + Overall MKV support

[enzomtpYT]

Hi ! I've been struggling while downloading some videos and i think some useful features could be added :

• Downloads of Subtitles
• Adding MKV support
• Downloading all audio tracks (from different languages) in one MKV
• Downloading all Subtitles (from different languages) in one MKV

I am sorry if i am asking too much, ill try to find some way to make what i want to do.

Thanks for make a such great program !

I would absolutely love to look into this! I've never had a use case personally for any of these but I'm willing to put in effort in implementing that :)

Which source are you trying to download from that supports multiple audio streams? I don't know of any personally.

Here is an example with multiple Audio Source & Multiple Subtitles : https://www.youtube.com/watch?v=mImFz8mkaHo

Also if this can help i found a way to download youtube subtitles by using YT-DL arguements : "--all-subs"

[sylviiu]

Noted, thank you. I'll look into this!

i actually never knew youtube offered multiple language audio tracks

Downloading with "--all-subs" would only fit with one use case (downloading with FFmpeg disabled, and downloading the original format without conversion -- which might not even embed the subtitles if possible) -- I'd have to find a way to embed it with FFmpeg as well. This can become a "metadata option" here:

leaving this as a note for myself

multiple language streams are found in the formats array with the same format ID; e.g. format id 233 has multiple indexes for each languages (233-0, 233-1, etc), where the note specifies the language

i can't tell if this is the same for all services, but crunchyroll languages are through different URLs.

Also, what do you mean by adding MKV support? What's missing from it?

All media encoding & processing is handled by FFmpeg (where applicable); MKV should be supported already?

[enzomtpYT]

Ok, wait till I get home and I will tell you more Sorry for making you wait

Sorry for the late response ! So mkv is already supported by FFmpeg, but after checking mkv support multiple audio streams, i wanted to know if it is possible to make something where you choose what to put (with checkboxes) and then at the end it merge all audio/videos and subtitles in one mkv files with ffmpeg, sorry again if it is too difficult !

[sylviiu]

Yeah, that would be possible. That's currently my plan for implementing this.

Sorry for being silent past couple days, I've been a little busy outside of software development :( I'll work on this soon!
