write ID, URL to metadata

[exekutive]

I would like to be able to write a Youtube video's ID and/or URL to the output file metadata. My testing suggests that, using the 'add-metadata' option only the writes the video title, channel name (author), and description.

version 2018.04.16

URL is already written.

[exekutive]

Please show me where.

Not all formats support this metafield.

[exekutive]

Sorry, I don't understand source code. Can you please elaborate ...
Is it an issue with the input format, or output?

I think it would be nice to at least write at least something, like URL or ID, to the album field or whatever. It's important to record where a video was downloaded from.

[exekutive]

which formats DO support it?

[Najrim]

I was trying to do the same thing. In case someone else is having trouble, here's how it works:

• Use the --add-metadata option when you download something
• Edit: you also need --audio-format to be opus, ogg or something else that can hold the purl tag. Mp3 doesn't work.
• Open the downloaded file in a tag editor such as Ex Falso. The url is in a field called purl.
• If you want it to be in the album field, find a method to copy it over.
  • In Ex Falso it's simple. Double blick purl and replace it with album or whatever you want it to be.

[exekutive]

Nope. Still don't see it.

[Najrim]

I only tried it with the --audio-format opus option. I think ogg and flac uses the same way of saving metadata so those should work too. What format did you use? I tried mp3 now and it doesn't add that tag.

[Najrim]

It doesn't need to be a pure music file. If your config is empty you will get the PURL tag in a mkv file if you do:

youtube-dl --add-metadata --audio-format ogg youtube.com/watch?v=videoid

[exekutive]

MP4, because it's widely adopted.
I never use ogg, flac or mkv.
Like I suggested before: If a URL tag isn't directly supported, then it could written to one of the many other tags, such as album (since it is not used anyway).

Seems someone is working on it: #17904

Really looking forward to this. Thanks @mx1up

When this is merged I think we can write something like --postprocessor-args "-metadata album=%(url)s".

[mx1up]

yep, that's correct :) it already works here locally but requires some review by @dstftw / youtube-dl team before it can be merged.

[exekutive]

Great! I hope the author decides it's worthwhile this time and not just dismiss it.

Not working anymore

[mx1up]

I'll have a look

[megapro17]

So I think problem is here #17904

It's not working for me. Is it still being worked on?

Just use webm or mkv

[exekutive]

no thanks. Those are useless formats.

[exekutive]

I think you need to unplug yourself from the computer once in a while.

[exekutive]

I think that it's none of your business what I use. I also think you are taking this matter far too personally. I also think you need a reality check. MP4 plays on everything. The containers you call "open and free" are actually "not widely adopted". I also think you have nothing valuable to add to this thread and are wasting your time.

[con-f-use]

So is there currently a way to embed the video URL in the meta data?

Because when I do something like:

$ youtube-dl --add-metadata --postprocessor-args "-metadata copyright=%(url)s" -f "bestvideo[ext=webm]+bestaudio/best"

What I get is:

---

What format people want is up to them. However, if they choose to use non-open ones, they shoudn't be surprised when other software can't play nice with their choice.

[exekutive]

MP4 uses a standard ISO container. Show me where it says you need licensed software to write metadata.

[sepehrkiller]

can we do anything to save in a txt file or in metadata file? or the .description file?
anyone knows anything about this? it would be cool to be able to save url in a txt file alongside the video

[jxu]

@sepehrkiller it is saved in --write-info-json which can be filtered with jq. alternatively --get-url gets raw url and --get-id gets video id to print to stdout
