Hi Derek,
Thanks for posting this job too. Well, Inderjeet here, again.
You have mentioned looking for best freelancers at lowest rate, which I feel is contradictory in itself.
The plugin/addon you have mentioned costs appx. $175 and does not work always. here is a text from their site:
"Only works for now in Chrome and Firefox browsers. Safari / Webkit / IE 11 will work with same origin videos, it does not have support for cross origin with the video tag therefore the canvas cannot obtain the image. A proxy work around is required to make it function."
The other GitHub plugin/addon, is for playing overlay ads but you're already have working preroll ads.
We can give you a flash app for the purpose but please be advised it will work only on desktops. Sharing and uploading will be a separate process. Let me know if interested.
Sincerely,
Inderjeet
