I was browsing through the Trac garden and came across this ticket by Ryan Boren https://core.trac.wordpress.org/ticket/28367 The ticket indicates that uploading video in WordPress leads to a dead end thanks to the lack of a clear and concise error message.
That’s an issue, but it’s an error message that’s all too common to so many people uploading large images, audio files, and video through the WordPress media library. It’s the primary reason I use the Add To Server plugin to import mp3 files into the media library after uploading them via SFTP.
This is one of those problems that if I were a developer of WordPress, I’d be furious because it’s a situation I can’t control. I’d be able to give a better error message, but I wouldn’t be able to convince webhosts across the internet to increase the upload_max_filesize and post_max_size to avoid seeing it.
With the default being 2Mb in most places which is tiny, how do you folks suppose we help WordPress deal with this issue so less user’s see that error when uploading things to the media library? I’ve seen a suggestion of using a script to do split file uploading but how would that work? Would WordPress and the webserver need to support it in order to function?
