Day 94 of 100DaysOfSpec, media elements
I am reading and taking notes on the HTML specifications for 100 days as part of #The100DayProject. Read the initial intent/backstory.

MEDIA_ERR_ABORTED: fetching stopped at user’s request (stop loading a slow web page, I think might be an example)
MEDIA_ERR_NETWORK: a network error stopped the fetch. This error would be thrown only if the UA already determined that the media resource was a usable file; same with
MEDIA_ERR_DECODE: now here’s the BS-y error! “An error of some description occurred”. Ok?
MEDIA_ERR_SRC_NOT_SUPPORTED: “The media resource indicated by the src attribute was not suitable.”
188.8.131.52 Location of the media resource
The only info I think might be new here since a previous section is that there’s a
currentSrc IDL attribute on the media element that gives…the current source. It starts out as an empty string, and could be accessed in scripting languages via
