I haven’t got a lot of time to respond at the moment, but a few comments.
Have all the re-bake jobs worked their way through sidekiq at the moment? Does https://yourforum/sidekiq show lots of jobs? If so, then it could just be that the Onebox-ing is taking time.
Take a look at this diagnostic that I carried out and attempt to reproduce the process and report back.
If YouTube banned you midway through a re-bake then you’re going to have to re-bake again as you won’t know what posts with embedded links have been processed or not. I actually wrote a utility to reformat YouTube posts and rebake in chunks.
Sadly, the Oneboxer seems to fail without a message so it’s difficult to know what the cause of it is. I had to fork and modify @merefield’s plugin to log the error messages to find out that I was getting 429 errors. You’re welcome to use my fork but it’s a bit of a hack and (I’ve just noticed) it’s a couple of commits behind Roberts.
If you are being rate-limited (you see 429 errors from YouTube) then I had success installing @merefield’s Onebox Assistant and enabling it but not changing any settings. i.e. leaving all settings blank. WARNING THIS IS WEIRD AND SHOULDN’T WORK BUT IT DOES.
Finally, to answer your questions about embed.rocks, I have signed up for an account with embed.rocks, tested it with the Onebox Assistant and it worked perfectly during a partial rebake. I have, however, since unconfigured it because it works with the weird behaviour described in 5.
In a forum that has been around for a while, it’s common to have once genuine YouTube links go stale. Videos are removed due to copyright or accounts being closed and so those links don’t work. Is it possible you’re seeing this?
edit: re-read posts here, and it appears that I have the same issues as you guys.
When you say they removed your ban in your message, I understand that you didn’t contact them, the ban was lifted without doing anything?
I don’t really care if my old posts don’t have embedded videos, but I care about new posts.
My forum isn’t open yet, and I’d like to offer my user a good experience.
edit : sorry for the multiple edit guys.
I tried the weird workaround described here: "Onebox Assistant", crawl for those previews reliably!
And it does work. I guess I’ll let the “rebake all” end, and since it seems that Youtube lift IP bans automatically, I’ll just wait a few days/weeks.
My forum stops one boxing youtube videos.
We started a topic with a lot of music videos a week ago and it seems that we have the same problem of @marcozambi oneboxing gets 404 error.
So, What should I do?
