A number of video_player and video_player_web integration tests are failing with:

The following PlatformException was thrown running a test (but
after the test had completed):
PlatformException(MEDIA_ERR_SRC_NOT_SUPPORTED,
MEDIA_ELEMENT_ERROR: Format error, The video has been found to be
unsuitable (missing or in a format not supported by your
browser)., null)

This seems to be an out-of-band failure rather than a regression, as it hit a number of open PRs in addition to the roller. video_player_web hadn't been published in almost a month when it started, so it doesn't appear to be a publish-based OOB failure as we sometimes see with federated plugins (and that would only explain video_player anyway, not video_player_web). My best guess is either something with Chromium on the CI bots, or something on the GitHub side with accessing the video via a GitHub URL.

This is blocking many unrelated PRs, so we're going to have to skip these tests for now, but this could end up causing us to lose a significant amount of video_player web coverage, so should be investigated as soon as possible.
