Ported from https://github.com/Haivision/srt with interop and bench tests


that is the question


I had this idea so many years ago, cheers for the execution!


Try out miro.com, the tool wasn't built for infrastructure diagrams, but you can do some amazing visualizations once you get comfortable with the tools there.

That said, I love this MVP! I created a quick diagram of some video systems I maintain and the experience was pretty good. <3 the svg export


> why isn't gif replaced by webm/vp9 yet?

Apple has significant market penetration, and you can't get VP9 to easily work in safari/iOS/tvOS


But why is this tolerated, for lack of a better word? There's no barrier to adding support, a decoder ships with ffmpeg. Youtube has been serving webm/vp9 video for years, so does that mean VP9 Youtube is unavailable on Apple platforms?

Youtube serves h.264 to Apple platforms.


Well not if users force VP9 using something like youtube-dl and pipe to a compatible player. But I looked it up and the reason Apple refuses to adopt VP9 is not so arbitrary but rather because they're part of MPEG LA, with HEVC being the competitor to VP9. It's unfortunate that there's so much fragmentation with standards simply because of corporate interests.


It is unfortunate but it’s been happening forever.

And yet, things continue to work and continue to progress for the most part, so format wars aren’t necessarily as big a problem as we like to think.


... but uses VP9 exclusively for 4k content, which is the reason why Safari doesn't support 4k Youtube videos.



That's got great attention to detail.

How do you handle the accelerometer differently for the different exercises (swim, push-up, curl-up, pull-up, run)? And how are you able to support swimming?


Great article! The process of using hardware to count calisthenics is certainly not trivial. Thank you for sharing your data and process.

Recently my consulting firm was tasked with detecting the calisthenics exercises (push-ups, sit-ups, and pull-ups) involved in the Navy SEAL physical screening test. After much research, we were able to use the accelerometer and gyroscope on the iPhone in tandem to achieve this. I was surprised at the level of success we were able to attain. You inspire me to write up a bit about how we were able to make this work.

Looks like a fun app, but the description makes my head hurt:

"This is a paradigm shift in fitness apps utilizing the best features in mobile technology moving one step closer to wearable computing to determine the physical conditioning level of athletes who want to test their mettle to see if they have what it takes physically to just get their foot in the door as a potential candidate to become a Navy SEAL, EOD, Diver, Special Warfare Combatant Crewmember, or AIR Rescue Swimmer? SEALReady guides you through a simulated physical screening test and lets you know how you stack up. It’s an intense mini triathlon without the bike but throws in a 500 yard swim using only a side, combat swimmer, or breast stroke, a minimum number of calisthenics, but you want more to score, and a timed GPS run."

Something like this might be clearer - it outlines what the app is actually for in the first couple of lines, and misses out all the empty buzzwords (paradigm shift? really?):

"Do you have what it takes to become a potential Navy SEAL, EOD, Diver, Special Warfare Combatant Crewmember, or AIR Rescue Swimmer? Check your physical conditioning level and test your mettle with SEALReady. SEALReady guides you through a simulated physical screening test - a 500 yard swim, calisthenics, and a timed run - and lets you know how you stack up."

A good copywriter could probably get that even snappier.

Oh, also, having your customer review be made from the same account name as your HN account doesn't make it look very convincing ;)


Yeah, I also work for the consulting company that developed this app and I couldn't agree more. I do feel compelled to say for our own sake that we do, in fact, advise our clients on things like App Store descriptions and app icons, but we don't always succeed. :-)


Hah, yes, I'm very familiar with that problem - my first ever commercial site got all its reasonably tight copy replaced by rambling lists of features and buzzwords from my boss's "marketing guy who really knows what he's doing"... :P


Thanks for the feedback. I'll forward your wording suggestion on to the customer.


I'd completely agree. Getting stuck loses you time and excitement about what you're doing. Getting stuck sucks.


Bravo, this site looks to meet the needs of many of us who want a one-click showcase. Great work with the domain management!


Great work, this kind of unattended service is great for days you just need good background work music...
