Treat blob: URLs as local in the resource selection algorithm (media elements)

[wolenetz]

Please port to w3c HTML5.1 the whatwg version of this fix (tracked in whatwg/html#1037, whatwg/html#295, and whatwg/url#126) to help the w3c MSE spec have less of a monkey-patch around fixing w3c/media-source#99 and to reduce potential implementor interop confusion.

This issue is fairly urgent, given the MSE spec timeline (we'd like to do a CfC for entering PR very very soon.)

@plehegar FYI - please help get this issue triaged and acted upon ASAP.
@foolip @annevk FYI

[travisleithead]

This has some urgency, setting CR milestone accordingly.

@travisleithead - Can you give the HME WG some idea of when this item will be processed? We are in the final steps of preparing a CfC to take MSE to Proposed Recommendation and MSE ISSUE-99 is currently blocked on this item? If you are not going to process this item this week, please let us know so that we can mitigate the MSE issue in some other way.

[wolenetz]

MSE issue 99 is no longer blocked on this item, but makes assumption that text like what is in whatwg/html#1037 eventually makes it into the w3c html spec.

Can someone restore @annevk's deleted comment? Or @annevk, can you post it again?

As an implementor, it's important to get the most accurate information. The W3C community should be providing this, no matter the politics or personal feelings involved.

@grorg I don't believe there was any technical detail in Anne's comment that could affect your implementation

[plehegar]

For what it's worth, the comment was reading:
[[
@wolenetz FYI, as long as you point folks to W3C HTML fork, there will be confusion and issues since it's in a bad state as explained here: https://annevankesteren.nl/2016/01/film-at-11. And has only gotten worse really.
]]

hi @adanilo!

Obviously this isn't the right place to discuss the politics (nor do I want to), but I think a comment from one of the HTML specification editors (on the WHAT-WG side) pointing out a potential source of confusion is important, even if it isn't completely technical. Deleting it was bad form.

Also, the originator of the issue tagged him.

[grorg]

Thanks @plehegar!

[plehegar]

On a different note: the MSE editors decided not to wait for the HTML editors: see w3c/media-source#143 .

[chaals]

Hopefully assigning the next milestone. @travisleithead, if that's not going to happen can you please change the milestone

[chaals]

@travisleithead re-scheduled. Please check.
