People with a 5-6M hit site are playing videos with the GCS I mentioned.You can't, my nigga. Most people just buy trial account and merge all of them on one project to pay invoice.
In a alternative look for someone to sell you a p2p player script to save some $$, but you need convert all vids on fragments.
I tried, but there was no solution.did you try juicycodes proxy player? it can be used with google teamdrive storages but no sure it can handle this much traffic because gdrive API has some limits
