There are 4 URL Parameters that can be used:

plFile

plVideo

plStart

plAutoClose

Two examples of how to build links in PDFs to other PDFs or Video:

https://playerlync-services.net/redirect?plFile=testfile.pdf&plStart=2         

https://www.playerlync.com/test/TestingThis.php?id=1&plFile=testfile.pdf&plStart=2

SideNote: "plStart=2" Starts you on page 2 or at 2 seconds within the video you link to. Additionally if your URL contains multiple parameters you'll need to separate them with an ampersand. (Example: ?plFile=test.pdf&plStart=2)

Auto close the video and return to the PDF:
