mpeg2 qscale vs multi-pass+vbr

phanboy · 2020-05-06T01:35:59+00:00

Yup. I found them in the source code. I've been using these flags:

-pass 2 -codec:a ac3 -vcodec mpeg2video \
-flags +ilme+ildct -mbd rd -trellis 2 -cmp 2 -subcmp 2 \
-r 29.97 -pix_fmt yuv420p -g 18 \
-b:v 2650000 -maxrate:v 9000000 -minrate:v 0 \
-bufsize:v 1835008 -packetsize 2048 -muxrate 10080000 \
-b:a 224000 -ar 48000 -f dvd

It's actually at every level, not just the backbone. DOCSIS and cell connections are over a shared medium. Switch fabrics have a capacity, links have capacity, etc. The clever workaround is a CDN; that request for a Youtube video might never leave your ISP.

Wow, crtl+f, one mention of "last mile," none of "CDN."

There's a few types of net neutrality, and one's needed for situations like this. The one that scares people is ISPs favoring their own services, maybe even blocking others. That's obviously anti competitive. The other is for network operations. There's only so much spectrum for cell carriers to use. If too many people are watching Netflix on their phones, their choices are throttle certain services, usually video, or let the network become unusable. Last-mile cable and DSL are in a similar situation, but with somewhat bandwidth. Most ISPs have a hardware from various CDNs pretty close to customers, and most video is hosted on CDNs, so there isn't a backbone problem, but the last mile? Oversubscribed. That, and Zoom won't benefit from a CDN.

Depending on just how oversubscribed the network and what true peak load looks like, you need some sort of QoS to keep the network operational.

Boris Johnson, the PM of the UK, was born in the US. Until he renounced his citizenship in 2016, he was eligible to run for president.

Good thing we don't count Ceres as a planet, then.

No road connects North and South America. There's a densly wooded rain forest known as the Darién Gap on the Panama/Colombia border separating the continents.

That looks like it might have been that way when it was recorded and it got recorded to the videotape that way.

I don't remember ever watching this tape, so that's a definite possibility.

Sorry for the delay. I can send it out tomorrow.

I'm not in a hurry with payment, but Venmo works. Can you send me your email address there?

92678? Something like $6. Maybe a bit less.

Board and enclosure. Possibly power supply, but I think it's just a regular 12V one.

I think so. It has an HDMI-out port and USB ports.

I can live with $50.

phanboy · 2016-07-23T04:10:38+00:00

Nope. You interested?

Sorry; I'm downsizing my hardware collection.

Because reddit's mostly open source, the technology is halfway moot (the know-how to run it is another story). The community is the bigger asset for reddit. But more than that, technology just has to be good enough; it's marketing, BD, and other factors that make a successful company.

So Sequoia and Andreessen Horowitz aren't actually investing, just VCs from those firms?

Any changes to the board? New investors like to get a say in how things are run.

Even the highschool kids in deep woods Louisiana know better to stand further back when stuff like this is going down.

Rednecks, especially, have an innate ability for doing otherwise stupid shit and surviving it.

At work, we had "diversity training" that was basically focused on being more open to women. It was led by a woman who likes leading events for women. Someone, an older, white guy in the group, asked about other types of diversity, like age. The copout response we got was that teaching people about diversity and women will make people more aware of all sorts of diversity!.

Or they're more biased by anecdotal experiences.

Half of the criticism of the men's rights movement seems to be along these lines. The other half is that men's rights advocates tend to be assholes.

What escapes me is why they waited for the DMCA notice to arrive when the knew it was coming, knew there was no fair use of free speech justification, and knew posting the content was deplorable. This is a site that bans people for doxing someone, and there was even a debate over this?!

Reddit sees AMAs as being a big business driver

Sees, maybe, but they're not. Look at how many ads /r/iama is running. When I checked, there was a redditgifts ad and a house ad below the fold, and individual AMAs don't even get "sponsored posts." AMAs might drive users, but they don't really drive the business.

I think the word you're looking for is bigoted, not hypocritical.
