I'm fairly new to phpbb3, only used it for about a few weeks now trying to familiarize myself with the layout. Currently I'm working on updating the board to support automatic video attachments. I've started this off with creating a custom mp4 bbcode tag for the extension group "flash", and works mostly as intended when you figure it out, but it isn't very user/new-user friendly.
What I think would work based on my knowledge
step 1. I think (if its possible) figuring out which attachment is part of the flash group
step 2. instead of flash group files being placed inline with the "URL" being something like "9tXO2v_CrowRUbLb_VipIZZI~_-~9eCt_wWxV4~.mp4" it'd be "https://forum.website.net/download/file ... view&id=92" (which can be found by right clicking the attachment filename and clicking copy link address) , additionally replacing the [attachment=0 ]/attachment tags with [mp4]
This is my first time posting on this forum so if I did anything wrong please correct me
