Load testing video streaming website

Hi

I need advise for one my current load testing project. The Application has been built with video steaming feature which needs to be load tested for at least 150 to 200 users. The videos has been shared through 3rd party - Vimeo.

We are using Loadrunner tool for testing. I'm trying to record the flow using Web http/html and the following has been recorded in VuGen.

https://player.vimeo.com/video/{videoID}?title=0&byline=0&autoplay=1;

followed by

https://player.vimeo.com/log/play",

https://vimeo.com/ablincoln/vuid?pid=0e17ae2d288717396921dcdd78540e3182058e01483706023",

Now I wanted to verify whether the video content has been fully downloaded and run fine during the load test. How Can I verify this??

Thanks,
Thiyagu
