How to do tags in the filesystem

[bakaouji 0]

Hi,

Apart from the Metadata manager, how else can I set up tags for files/folders/collections? Which (if any) of the following options exist for tagging:

1. - nfo / xml files
2. - Extract from folder or file names
3. - API?

If so, can I please get a link or further details. I can't find anything on the knowledge base.

I was looking to set up tags like HDR, 4K, Blu-ray, 1080p.

Hi, you could add tags to nfo files.

Hi,

I have gotten nfos to work to a certain extent by following the kodi standard. I created a tvshow.nfo in my Altered Carbon folder with this format:

<tvshow>
    <uniqueid type="tmdb" default="true">68421</uniqueid>
    <tag>Blu-ray</tag>
</tvshow>

Folder structure:

Altered Carbon
- Altered Carbon S01
 - Altered Carbon S01E01 
 - Altered Carbon S01E02
- Altered Carbon S02
 - Altered Carbon S02E01
 - Altered Carbon S02E02
- tvshow.nfo

Then I did a refresh of metadata on the Altered Carbon folder. The blu-ray tag is scanning correctly.

However, if I change the nfo to:

<tvshow>
    <uniqueid type="tmdb" default="true">68421</uniqueid>
    <tag>HDR</tag>
</tvshow>

I don't see any tags. The only tags that are working for me are Blu-ray and 720p. 

Do you know why that could be?  I also tried saving HDR from the metadata manager, but it still doesnt persist.

That's strange. @Happy2Play are you able to reproduce this?

I just randomly chose a Series and added <tag>HDR</tag> to that Series and did a Scan library files and refreshed the page and that tag appeared for the series.  I then changed the tag to <tag>This is My Changed TAG</tag> and did a Scan library files and refreshed the page and that tag appeared for the series.

This was all manually editing the nfo file.  But tested via the UI and had no issues either.

Hi Guys,

After i restarted my server, it started working fine, no issues with tags being picked up :)

Sorry, I forgot to post my update here.

Thanks for the update.

Can you mark the thread as answered?

Sorry, for reviving such an old but I have a few questions on this approach:

1. Does this also work on episode level?
Just did a quick test and it worked fine for TV Show and Season level but on episode level it didn't pick up the <tag> of the NFO I edited.

I think I found the answer in the logs:

I probably just misplaced the <tag> information and therefore Emby didn't pick it up, right?

2. Will Emby remove the tags again if I remove them from the NFO?

Yes, episodes support tags, and that error looks like you have malformed xml.

Yeah, I think so.
Will need to do some further testing.

Yes, but there's an open issue where removing all of them won't do it, which @Happy2Play can link you to.

That reflects my testing as well.
When remoivng the tag I added to the NFO on season level it just got added back again by Emby.

Shouldn't be a big issue for my usecase though.
Thank you!

@neik - have you investigated adding tags via the API ?

It's easy to add/remove them via a curl command or other API integrations - it may be easier than relying on NFO's.   Once added, it then writes the tag's back to the NFO anyway and visa versa.

Something to think about..

I had a short view on it but maybe I need to dig deeper.

Will have another look once I can find more time.

I'm struggling on identifying the files that have portuguese subtitle (internal or external) or portuguese audio available.
Asked ChatGPT got this:

Quote

You can retrieve a list of items by making a GET request to the endpoint /Items with the appropriate query parameters. For example, you can use the IncludeItemTypes parameter to specify that you want to retrieve only video items, and the Fields parameter to specify the fields that you want to include in the response.

To filter the list based on the presence of a Portuguese subtitle, you will need to iterate through the list of items and check the MediaStreams property of each item. The MediaStreams property is an array of objects that contains information about the audio and subtitle streams in the item. Each object in the array has a Type property that indicates whether the stream is an audio or subtitle stream, and a Language property that indicates the language of the stream.

Here's an example of how you could use the curl command to retrieve a list of video items, and filter them by Portuguese subtitles:

curl -X GET -H "Authorization: Bearer ACCESS_TOKEN" "http://emby_server_url:8096/emby/Items?IncludeItemTypes=Video&Fields=MediaStreams" > items.json

(...)

Replaced the ACCESS_TOKEN part with a newly generatd API Key but all I get is "Access token is invalid or expired.".

Any hint is much appreciated.
Thank you!

The authorization header doesn’t look like it’s formatted correctly.

So something like this

curl -X GET "http://localhost:8098/emby/Items?HasSubtitles=true&Recursive=true&Fields=MediaStreams&IncludeItemTypes=Video&api_key=yourapikey" -H "accept: application/json"

Don't see it in the api but add &SubtitleLanguages=por within the query.  But may be different language codes.

I got this from filtering a library with subtitlelanguage and looked at the query in the server log.  So filtering a library with all your variables will show the query in the server log to better build your command. (debug logging)

Movie with por subs

curl -X GET "http://localhost:8098/emby/Items?HasSubtitles=true&Recursive=true&Fields=MediaStreams&IncludeItemTypes=Movie&SubtitleLanguages=por&api_key=yourapikey" -H "accept: application/json"

all with por subs - remove include type movie

curl -X GET "http://localhost:8098/emby/Items?HasSubtitles=true&Recursive=true&Fields=MediaStreams&SubtitleLanguages=por&api_key=yourapikey" -H "accept: application/json"

Thank you, Happy! 

Tried to do a little bash script to loop through all the ID's and add the tag "Portuguese" to the items.
Question: Will this do what I want it to do?

#!/bin/bash

curl -X GET "http://localhost:8096/emby/Items?HasSubtitles=true&Recursive=true&Fields=MediaStreams&AudioLanguages=por&api_key=xxxxxxxxxxxxxxxxxxxxx" -H "accept: application/json" > audio.json

curl -X GET "http://localhost:8096/emby/Items?HasSubtitles=true&Recursive=true&Fields=MediaStreams&SubtitleLanguages=por&api_key=xxxxxxxxxxxxxxxxx" -H "accept: application/json" > subtitle.json

IDS_LIST=$(cat audio.json | jq '.Items[] | select(.MediaStreams[].Language == "por") | .Id')

for id in $ID_LIST; do
  curl -X POST "http://localhost:8096/emby/Items/953736/Tags/Add?api_key=xxxxxxxxxxxxxxx" -H "accept: */*" -H "Content-Type: application/json" -d "{\"Tags\":[{\"Name\":\"Portuguese\",\"Id\":\"Portuguese\"}]}"
done

IDS_LIST=$(cat subtitle.json | jq '.Items[] | select(.MediaStreams[].Language == "por") | .Id')

for id in $ID_LIST; do
  curl -X POST "http://localhost:8096/emby/Items/953736/Tags/Add?api_key=xxxxxxxxxxxxxxxx" -H "accept: */*" -H "Content-Type: application/json" -d "{\"Tags\":[{\"Name\":\"Portuguese\",\"Id\":\"Portuguese\"}]}"
done

I would just run it but it might cause some damage (e.g. mislabeling) I would like to avoid.

PS: ChatGPT isn't that cool after all... haha
