Support Piped/Invidious

[GlenLowland]

Please add support for 3rd party front-ends, similar to SponsorBlock. Specifically, for Piped.

[codenyte]

Invidious would be nice as well, I use Piped myself, but it's always better to have multiple options

[ajayyy]

Do note that this implementation will only work in some cases, since it is relying on cached information existing.

It will only work if someone with the main extension has seen that video once previously.

Stuff I changed:

• Fixed the title replacer, so that when it replaces the title of a video on a /watch page, it doesn't remove the button to switch between video and audio-only mode.
• Tweaked the formatting of some of the code to be more consistent.

Edit: It looks like Invidious does something with the title, so duplicate text may appear. Looking into it. Fixed.

Edit 2: Fixed another mistake.

[solisinvictum]

Thanks for your afford to make this possible.

But i dont know, and didnt find a option or so in dearrow, where i could put this user script in.

[gBasil]

Userscripts are managed with a different extension (like Violentmonkey), not DeArrow.

[aggarwalsushant]

@gBasil seems your script doesn't work at all as of now (may be due to a change in invidious or what). I tried with violentmonkey in Brave and FF. Didn't make any changes to your script whatsoever.

[ajayyy]

I have correct some issues in the script:

1. Data is already returned sorted in the correct order, should always use [0] if it is locked or has votes
2. Fixed how random time is handled

I've modified Ajay's script again.

1. I've added a simple polyfill for the fetch API that uses a GreaseMonkey API, which should get around CSP issues.
2. I've added a function for converting Blobs to data URLs, as the blob: URLs from URL.createObjectURL can be blocked by CSP.

@aggarwalsushant This may fix your issue. Also, you have to change the URL in @match to the URL of whichever Invidious instance you're using.

[solisinvictum]

thanks! that works great.

[aggarwalsushant]

@ajayyy @gBasil worked great now. Thanks. 👏🏽 Obviously the counters in the Dearrow plugin won't rise as it's the ViolentMonkey doing the things now. Will this script work for Piped instances too?

[aggarwalsushant]

Seems doesn't work with piped for now.

[ajayyy]

For Piped

https://github.com/TeamPiped/Piped/issues/2575#issuecomment-1641269041

Hi, we now have DeArrow support in a few places - feed, trending, and related videos. It's disabled by default but can be enabled in the preferences.

It looks like it doesn't support random thumbnails

[FireMasterK]

Piped now has native support for DeArrow everywhere with https://github.com/TeamPiped/Piped/commit/9539d51126c0a53f10d084d3fdbc2c677fb6ac28.

It looks like it doesn't support random thumbnails

Is there any explanation on what this feature is supposed to do? The API documentation currently doesn't have any information on what the randomTime is supposed to mean. My guess is that it is a random number between 0 and 1, and has to be multiplied with the video duration, and that has to be used as a thumbnail?

I've got another question - what happens when DeArrow doesn't have a video in its database? Piped fetches DeArrow content using k-anonymity, and we have a lot of null responses because it can't find a video.

[ajayyy]

@FireMasterK

Correct, there is this part in the documentation

Random time and video duration are used if you want to fallback thumbnails to a screenshot from a random time. To make thumbnail caching possible, this random time is consistent and produced by the server. The random time value is a number between 0 and 1 and must be multiplied by the video duration. For convenience, the API returns the video duration if it is known, but for most videos the server does not know the video duration. When the API returns a video duration of 0 or null, you must either not use this feature, or obtain the video duration using another method. The browser extension will fallback to fetching the video duration using other methods to always be able to use the feature.

If you'd like to wait on the thumbnail generator supporting the 0 to 1 numbers directly (which I plan to do), so you don't have to deal with getting the video duraton yourself, you can track https://github.com/ajayyy/DeArrowThumbnailCache/issues/4

As for what to do about videos not in the request due to using k-anonymity requests, I'm not sure of a good solution. These numbers are generated using a seed random with the videoID as the seed. Specifically, they use the alea algorithm in https://github.com/davidbau/seedrandom/blob/released/lib/alea.js. When k-anonymity is enabled in the browser extension, it falls back to finding the randomTime value using this library on the client side when needed. I don't know a good solution for Piped though since it is not in JS, so cannot use that library. Maybe in this case it needs to fall back to an original thumbnail until a solution to that part is determined.

[FireMasterK]

I have ported an Alea implementation to Java. The random numbers generated from the seed don't seem to match however:

DeArrow: https://sponsor.ajay.app/api/branding?videoID=VyI-2c9KI1I

The randomTIme for this specific video is 0.16970540321403121

[ajayyy]

@FireMasterK nice!

check on a video without SponsorBlock segments (they are the ones that wouldn't appear in the hash based API). If there are SponsorBlock segments, then it uses those to not choose a timestamp in a segment

Strange, works for me on my own instance. Try checking the console in the browser dev tools and look for error messages.

This is what is in the console.

and tell me if it fixes the issue? Some instances appear to have their href placed differently (a version thing maybe?)

[ghost]

and tell me if it fixes the issue?

Not the same person you were talking to, but this version of the script worked somewhat for me on a small personal instance while the previous version didn't (only found this thread yesterday).

It replaces the thumbnails correctly when one is available, but for any video that it can't find a user thumbnail for it won't replace it back with the original, does the script not do that or is that something going wrong somewhere? I'm on Firefox on Linux, using Violentmonkey, but the same thing happens with Tampermonkey, even if I use a freshly installed Google Chrome.

This is all that's in browser console

[gBasil]

So the issue seems to be that sometimes the Dearrow server responds with a Cloudflare 502 error and just returns an HTML page, presumably because it gets ratelimited by YouTube. I've updated it so that it only replaces the thumbnail if it receives an image.

Sry for the late response @gBasil

Your latest submitted script here, works again!

Great. Thanks!

[Sommerwiesel]

@gBasil One Problem with your userscript: The thumbnails for YouTube shorts is in portrait format and the enclosing container (div) changes to portrait as well, breaking the style of any feeds page. You should probably add a CSS rule with a max height or something like that.

Screenshot


[gBasil]

@Sommerwiesel Could you give me a link to a page (i.e. a channel page) so that I can reproduce that? I block the vertical Shorts videos with uBlock Origin, so I haven't run into this myself.

[Sommerwiesel]

@gBasil It's not a problem on channel pages because on there, shorts are in a separate category (videos and shorts) and thus, the different height does not break the style. It only happens on the feeds, where videos and shorts are mixed together.

You can create an account on my instance if you'd like and test it with this channel in your subscription feeds, they release shorts regularly:

https://invidious.nerdvpn.de/channel/UCchBatdUMZoMfJ3rIzgV84g

Also, can you share your ublock rule for blocking those pesky shorts? I'd like to have that, too :D

[gBasil]

The issue seems to be that Invidious returns the YouTube Shorts thumbnails with the same ratio as non-Shorts videos, meaning that it has the padding around it. However, DeArrow returns the thumbnail in the mobile orientation. I think the best solution would be for @ajayyy to do something on DeArrow's end (potentially by adding an endpoint that adds padding to the sides of the images?) in order to not have it break if an Invidious instance has custom styling.

Also, can you share your ublock rule for blocking those pesky shorts? I'd like to have that, too :D

It unfortunately isn't very reliable and ends up blocking streams and other things sometimes, because it just blocks videos that don't have a length. I wish there was an option to hide them entirely that didn't rely on hacks like these. But here it is:

owo##.pure-u-1.pure-u-md-1-4:not(:has(.thumbnail .length))

[BurntEmbers]

The dearrow script no longer works, not even the latest version. Has anyone been updating this or not? With youtube's new hostility to adblockers and purposely making your CPU faster, I'd love to fully move over there now, and I have gotten way too used to dearrow decrapifying searches and titles.

[gBasil]

I've been running into issues as well. I was hoping there would be an official integration in DeArrow by now.

@ajayyy Is this planned down the line, and if so, do you have any estimate as to when?

[ajayyy]

The main issue would be integrating channel allowlists which uses a YouTube api to get the channel ID. I haven't thought of a good solution for that yet.

[gBasil]

The main issue would be integrating channel allowlists which uses a YouTube api to get the channel ID. I haven't thought of a good solution for that yet.

@ajayyy I'm not entirely sure which ID, but doesn't Invidious have the channel ID (in the old format, at least) in the channel link under the video?

[gBasil]

Hey all, I've quickly updated the userscript to support what I believe is the new Invidious HTML layout. If you had errors previously, this'll hopefully fix them.

Still hoping for an official integration though :P

Consider publishing the userscript on Greasyfork

Consider publishing the userscript on Greasyfork

@codenyte The issue is is that the userscript needs permissions to access all Invidious sites. I could theoretically write a detector and allow the userscript to access all sites, but I don't know of a good way to do the detection.

[codenyte]

Right, I completely forgot about this

Piped now has native support for DeArrow everywhere with TeamPiped/Piped@9539d51.

Well, for the frontend. However, as far as I know, one can't do any submissions yet. That would be quite helpful.
