Using this link, I had been able to embed a video, autostart it, and even seek to a specific time.
https://drive.google.com/file/d/<file-id-here>/preview?autoplay=1&t=50s
While that link still works full screen for embedding, auto-start and time seek no longer are working. This api works, but it seems to be a temporary signed link specific to each user, so it works locally, with jwplayer embedding it (for autostart/seek time functions), but anyone else I sent the page to with my generated link inserted into jwplayer, it returns 'error loading media: file could not be played'.
Is there anything else I can do, or am I basically screwed?
