Suddenly seeing "There was an error playing the video" on all videos and records

[MlleBae]

We display this component directly on the File/ContentDocument record page if the filetype is mp4, but I just noticed that it's showing the error message and never showing the video.
I checked the other application of this component (on Chatter Groups), and I'm seeing the error message there at all.

No change to my browser, browser settings, file settings, etc. since it last worked.

Is this still occurring?

Hey there, I'm getting the same error right after LWC installation to a scratch org. It happens both on record detail page and on file detail page, the video player pops up for a second and then the error is shown. Guys on Appexchange mentioned that we need to add some URLs to CSP, but which ones exactly?

We recently implemented this and are seeing the error in production. From doing some digging, it seems that Chrome is throwing a CORB error due to a mismatch in MIME type. Is there something that can be done within the component to ensure that it is sending the proper MIME type and not just text/plain?
