👍 Thanks for opening a new pull request.

The master branch won’t be released until the v6, which could be a while from now. Would you have any interest in backporting this to the 5-stable branch, which I was planning to release in the next couple days? I’d love to get this into the next release.

👍 would love too!

I get the following error with files over 30 seconds: "Twitter::Error::BadRequest: Large file can not be finalized synchronously." Do you have any idea how to fix it? Can it be fixed? Or does the endpoint just not support files > 30 seconds like the documentation says. I'm just trying to figure out if it's possible to upload videos up to the 10 minute maximum...

Happy to contribute the fix if you can point me in the right direction. (if there is a fix)

There seems to be very little information about videos with 10 minute limit. I'm guessing it's something only allowed through the Twitter family of apps. If you know differently, please let me know. Thanks

What is the size in MB of your video?

[maxschmeling]

17.9 MB

The code in this pull requests appears to be using the chunked upload automatically... unless I'm missing something.

[PuKoren]

You are right, I was looking at the wrong direction

@sferik sorry, somehow didn't get notifications here. I'm swamped currently, but if I find a minute I'll backport it.

any example or api class to upload the media and get response back in the form of media ID.
