You need to set the permissions on your Google Drive clip to make it publicly accessible, otherwise you'll have to grant permission to every person that requests access. See the
Share a file publicly section in this Google
FAQ.
I also have a Blackvue camera and while PD19/365 can work with the HEVC clip without any problem, PD14 crashes as soon as I try to import it. I have a linked clip in this
post.
In the long run, I think it's going to be easier to just set the dashcam to record in AVC (H.264) rather than HEVC (H.265) unless you upgrade to a newer version of PD. The files will be larger but you won't have any issues working with them straight out of the camera or off the micro SD card.
