Embed youtube videos

Help
1

Hi,

Trying to embed a youtube video but constantly getting the “Error 153”. Tried it with both iframes and and the built-in way (“…”) but no matter what I do it shows the Error 153.

Running version 1.9.14.

Did youtube disable embedding being possible?

Thanks in advance for any potential help.

Can’t edit but what I meant with the built in way was the syntax below.

It’s a YouTube issue affecting a bunch of apps. Hang in there a bit for the fix:

Hi Spheredb,

This bug has been ongoing since the 13th Sep 2025

If you don’t have too many notes you could use the “Featured Image” Plugin

See my tutorial video here

Sounds like it will be fixed in 1.10.3 as Whitenoise said but no ETA

Thanks. It’s annyoying that the full folder update doesn’t work with the plugin sometimes…?
So I made this script:

import { App, Plugin, TFile } from 'obsidian';

const addYtLinkTemporarily = async (app: App): Promise<void> => {
    const activeFile = app.workspace.getActiveFile();
    if (!activeFile) {
        console.log('Yt-Link-Adder: No active file');
        return;
    }

    console.log('Yt-Link-Adder: Active file found:', activeFile.basename);

    // Read the current content
    const content = await app.vault.read(activeFile);
    
    // Find any YouTube URL in the content
    // Matches: youtube.com/watch?v=, youtu.be/, with or without https://, www., etc.
    const ytRegex = /(?:https?:\/\/)?(?:www\.)?(?:youtube\.com\/(?:watch\?v=|embed\/|v\/)|youtu\.be\/)([a-zA-Z0-9_-]{11})/;
    const ytMatch = content.match(ytRegex);
    
    if (!ytMatch) {
        console.log('Yt-Link-Adder: No YouTube URL found in the document');
        return;
    }
    
    const ytLink = ytMatch[0];
    console.log('Yt-Link-Adder: Found YouTube link:', ytLink);
    
    // Find the second "---" in the file
    const separator = '---';
    let firstIndex = content.indexOf(separator);
    
    if (firstIndex === -1) {
        console.log('Yt-Link-Adder: First "---" not found');
        return;
    }
    
    let secondIndex = content.indexOf(separator, firstIndex + separator.length);
    
    if (secondIndex === -1) {
        console.log('Yt-Link-Adder: Second "---" not found');
        return;
    }

    console.log('Yt-Link-Adder: Second "---" found at position:', secondIndex);

    // Calculate insertion point (right after the second "---" and its newline)
    const insertPosition = secondIndex + separator.length;
    const imageLink = `\n![](${ytLink})`;
    
    console.log('Yt-Link-Adder: Inserting image link...');
    
    // Insert the image link
    const newContent = 
        content.slice(0, insertPosition) + 
        imageLink + 
        content.slice(insertPosition);
    
    await app.vault.modify(activeFile, newContent);
    console.log('Yt-Link-Adder: Image link inserted, will remove in 4 seconds');

    // Wait 4 seconds, then remove the link
    setTimeout(async () => {
        const currentContent = await app.vault.read(activeFile);
        const updatedContent = currentContent.replace(imageLink, '');
        await app.vault.modify(activeFile, updatedContent);
        console.log('Yt-Link-Adder: Image link removed');
    }, 4000);
};

export class YtLinkAdderPlugin extends Plugin {
    async onload() {
        this.addCommand({
            id: 'yt-link-adder',
            name: 'Add YouTube link temporarily',
            callback: () => addYtLinkTemporarily(this.app)
        });
    }
}

export async function invoke(app: App): Promise<void> {
    return addYtLinkTemporarily(app);
}

Must be used with the CodeScript Toolkit plugin. Save it with some name with .ts extension. Open a file and press the key combo you attached to the script.
Adds the embed link below the YAML block and removes it in 4 secs, enough time to trigger the Featured Image plugin to scrape the YT thumbs.

It helps if there is a unique YT link in the note, otherwise, if there is more than one URLs, it uses the first one it finds in content.
