Add metadata and thumbnail while downloading files

There is no option to embed metadata and thumbnails while downloading files.

Is your feature request related to a problem? Please describe it

No

How will you/everyone benefit from this feature?

Metadata information like chapters, artist, album name, genre, year and thumbnail can organize audio files easily. Similarly for video files.

I'm surprised this isn't a duplicate. There is literally no issue asking for metadata to be added to downloads. O.o

How does youtube-dl do it?

Regarding thumbnails, they can only be added to the mp4 container, not ogg. (Technically they can, but it needs a hack; the image needs to be converted to base64 or something.)

Metadata can and should be added for audio as well as video files.

youtube-dl doesn't add metadata by default, but you can with --add-metadata option.

[indahud]

It uses these flags --embed-thumbnail --add-metadata

this would be very cool... especially for audio files

@B0pol And it will add the image too? In full quality?

I'm here from a request I wrote here, btw:

It would not be a good idea to add a very high quality image to the downloaded file. If your file is 4 MB and you add another 2 MB just to get a thumbnail, for example, it would bloat your media library very fast.

@opusforlife2 I don't think I ever saw a ridiculously large image for it that it takes this much space, from YouTube, and I use "mediahuman youtube to mp3 converter" on many videos from there.
In fact I never even saw a 4k image from there, so I think it should be safe.

You could always have a setting for protecting it, if you really want:

1. Disable adding image
2. add image, only if up to widthxheight resolution. Downscale if needed.
3. add image, only if up to x MB. Downscale if needed.
4. add image, only if up to x MP. Downscale if needed.
5. always add image. No downscaling.

And because I really never saw such an issue.

I got the 2 MB figure from here. So it is possible that an uploader uses an image of that size.

But Youtube provides thumbnails in several sizes. From very small to full sized. That's what I was referring to. We could get an optimum sized image that looks good but is still small.

And yes, we should definitely have a setting to control this. Users who don't want thumbnails shouldn't have to pay for them in data.

@opusforlife2 It's the guidelines, and even then, it's incredibly rare for an image of size 1280x720 to take this much space.
It will probably need to have such random content that the compression of JPG/PNG will fail to compress it well.

I don't think you need to worry about this much.
We could have a generous default setting and you wouldn't notice it.

If you want, you can try to upload the largest thing you can, and I can test what I get from it.
