I have possibly the same issue, or similar. It seems like the module gets stuck at times in a no-load state. We do not see errors, the video simply will not play to a blank background. In our case, though, this is not a consistent behavior as at times it loads fine, on the same target video. Normally I would think it buffering/load time or some other connectivity related cause, but it seems more like an initialization failure as it will never load when it is doing this if you just wait. Reloading or bringing up a different browser often will yield different results. I am planning to do some more triage, more widely varied size and format of videos to see if I can point to a root cause, but hopefully it’s already a known issue that just needs a patch.
