On the topic of resource loading issues, another security fix in version 68 stops access to cameras and microphones in non-secure contexts
such as http, and, presumably, file://.
However, it looks like “cameras and microphones” also includes “other media devices”, as described at this link (scroll to the DOM APIs
And “other media devices” apparently includes video playback.
We are now seeing an issue playing instructional videos (mp4) from an tag. When accessing from both file:// and from http://,
we get a blank page, with no content, and no errors in the console. When accessing from https://, the video plays.
I have tried giving the site permissions to access media devices, with no success. Even if I can get http working, I assume file:// would
still be broken.
Have I diagnosed this properly, i.e. is this video issue related to the “cameras, microphones, and other media devices” as described
by Dan Callahan in the link above?
