In general we have preferred that videos are hosted on the LLVM server as the
official hosting site but I can see the argument about slow download speeds.

Youtube has been discussed in the past but we have usually defaulted to mainly
hosted on llvm.org <http://llvm.org/> and then a copy could potentially be
on YouTube. I would want this to be an official posting though.

There is another option that was presented to the LLVM Foundation as a free
hosting service, which I will need to talk to them more about (I would rather
not say on list just yet).

I’ll get back with a answer/concrete proposal.

Thanks,
Tanya

Just as a point of reference, I downloaded a 1.5 GB mp4 file from llvm.org this
morning in about 15 minutes over a Comcast cable Internet connection in
Minnesota. Perhaps the slowdown is not at llvm.org? The YouTube regional servers
would certainly help anyone not in North America.

Youtube is used by many foundations and conferences out there as the
official channel for their presentations, tutorial videos, outreach,
etc.

It can also be embedded in web pages, and there are good builtin
plugins for all mobile platforms and browsers. It's not as easy to
make an mp4 work out of the box in a way that you hope it would.

I don't see a problem in hosting the videos *in addition* to having
them in a CDN, but especially because Youtube is free and ubiquitous,
anything else (maybe apart from Vimeo) would be less ideal, especially
if they require plugins for browsers or mobiles, even if they're free.

cheers,

Anything that doesn’t *offer* a download option (breaking ToS is not an option)
shouldn't be considered as the primary hosting IMO, which disqualify Youtube
IIUC their ToS.

Tanya's proposal seems nice: having the video hosted by llvm.org and
mirrored to Youtube would be a good tradeoff.
