Additional context
It would be awesome if we could provide a timestamp for the start and one for the end and only download that part of a given video

[StefanLobbenmeier]

Yeah I definitely plan on doing that in v3. Current GUI idea is having an edit button on the duration where you can change that

I just had a deeper look into the project.
Does youtube-dl even allow to download only parts of a Video? I havent found an option for that.

[StefanLobbenmeier]

Yeah it’s part of download sections: https://github.com/yt-dlp/yt-dlp?tab=readme-ov-file#download-options

       Download only chapters that match the
                                regular expression. A "*" prefix denotes
                                time-range instead of chapter. Negative
                                timestamps are calculated from the end.
                                "*from-url" can be used to download between
                                the "start_time" and "end_time" extracted
                                from the URL. Needs ffmpeg. This option can
                                be used multiple times to download multiple
                                sections, e.g. --download-sections
                                "*10:15-inf" --download-sections "intro"

(I also plan to allow you to select the target chapter in that same UI, this is what chapter information I get for https://www.youtube.com/watch?v=eLVAMG_3fLg)

  "chapters": [
    {
      "start_time": 0.0,
      "title": "Intro",
      "end_time": 124.0
    },
    {
      "start_time": 124.0,
      "title": "Unstoppable Vine Robot",
      "end_time": 913.0
    },
    {
      "start_time": 913.0,
      "title": "Update on Vine Robot!",
      "end_time": 1224.0
    },
    {
      "start_time": 1224.0,
      "title": "Highest Jumping Robot",
      "end_time": 1935.0
    },
    {

Did you find some time to work on this.
If not I might have some time on hand to look into it.

[StefanLobbenmeier]

Not yet - are you also comfortable with jetpack compose / could implement it in v3?

otherwise I will have more time in dez / January

[RFDarter]

Nnot really. I never uses jetpack compose.
I guess you are talking about this?
