Hello,
I'd like to use Allvideos to embed mp3 files stored remotely on Amazon S3,
but also using the linklok url software (www.vibralogix.com/linklokurl/)
to dinamically create those file urls and protect the original Amazon S3 urls from viewing and hotlinking,
sintax should be something like

{mp3remote}<?php linklokurl('audio.mp3',10,1,3); ?>{/mp3remote}

output of the link something like

www.mysite.com/linklokurl.php?linklokauth=dGVzdC56aXAsMCw5NC4zOC4yMDIuMTc2LDAsMSxMTF8wLCwxMjcyMTlmMTU1MWYyZDFiNTkwMDYzYmY1ODUxMGRiNg%3D%3D/audio.mp3

the link will change everytime the page is refreshed

I haven't bought linklok url yet so I can't test

someone knows if a method like this will work with Allvideos?

Thank you!

Since there is no definite URL to point to the mp3 file, then AllVideos has no way of determining what the URL is. This will always result in a 404 error.

I have tested this and it works, actually :-)

This script (linklok url) create the link dinamycally inside Allvideos tags, and the player is reproducing the file correctly

For all those who are using this script, I've got some amazing support
from the developer, best if you use Sourcerer plugin (Nonumber.nl) to get the php code working,
this is the code I am using

Yes without a plugin it will not work inside an item/ article.
You can use it in a K2 Tools modules though without the {source} tags.
