Way back in 47 (version that is), Chrome started to mandate the use of HTTPS in conjunction with getUserMedia. To use HTTPS you need a SSL/TLS certificate. Xander Dumaine covered this a bit for us before, but I still see a lot of people out there struggle with it. As it so happens, the certificate for my […]

Guess what? Mozilla is removing Hello from Firefox.
It will still be available as an add-on, but it seems to have degraded in its importance to Mozilla, which is understandable.
Goodbye HelloWhat is/was Hello?Hello was Mozilla’s attempt to build a video calling service. Something that is baked right into the browser, but can be used by any browser supporting WebRTC. Think FaceTime or Hangouts but without the app or even a website.
Mozilla partnered for Hello with TokBox (a Telefonica company), which provided the backend to the service – mainly NAT traversal as far as I can tell.
When Hello was announced, I had my doubts and questions about it.
What went wrong?A few things were wrong from the onset in Firefox Hello:
The main issue though is that a free video calling service isn’t that much of a deal these days (if this surprises you – just ask Google).
So Mozilla started by embedding Hello right into the browser. Then making it into a system add-on. And now it is making it into just another add-on. I assume it has a lot to do with the usage they’ve seen over the past year for Hello (and its non-adoption). It makes no sense to continue investing the time and effort in it if no one is using it – and having it officially released with the browser once every few months is a waste. Better throw it out of the browser and simplify the browser releases.
The next step might be to sunset the add-on/service altogether and say goodbye to Hello.
Is this predictive to Google’s Duo app?Google announced Duo and is about to release it. Simplifying things a bit (and dumbing it down), Duo is a FaceTime clone. I covered Allo/Duo a few months back.
On face value, there’s no reason why Google Duo won’t meet a similar fate as Mozilla Hello.
That said, there are a few notable differences:
Will this be enough for Google Duo to get the adoption? I don’t know.
Where do we go from here?In 2016 there should be no doubt anymore:
If you plan to monetize a video calling service, you need a serious business plan.
Most services I see launched have no business plan. They attempt to grow to millions of users. There’s a lot of dumb luck involved in it.
I’ve had my doubts about the viability of Wire as a company due to the same reasons. The only progress made by Wire is open sourcing their app – this doesn’t strike me like a business plan or a signal of strength and healthy growth.

Huawei ME909s-120 is the newest modem of Huawei LTE/UMTS family, and it is sold for around $70 at TechShip.se and at Aliexpress.
The modem is immediately recognized as CDC Ethernet device in Debian 8 kernel, and is visible as usb0 interface. In the scripts below, the ttyUSBx serial ports are aliased to ttyWWANxx, and usb0 is renamed to lte0, in order to avoid any naming conflicts with other devices, and also to avoid possible name changes due to a kernel upgrade.

For example, SIM cards of one of our providers get into faulty state every few weeks, and only a reset helps.
The GSM module can either be rebooted via Web GUI, or from the Asterisk console. But the Asterisk console can only work on the same host where the asterisk daemon runs, so you need to make an SSH connection into the Yeastar box to do that. Also it’s impossible to save a public SSH key in a Yeastar box, so only password authentication works.
Ansible is a powerful toolset for managing remote hosts, and it appears to be perfectly suitable for managing the GSM gateways.
Ansible 2.x is available for Debian 8 from jessie-backports repository. There are some important differences from version 1.7 that is installed from default repositories, and in particular, ansible_host and ansible_port variables.
After installing Ansible, uncomment host_key_checking = False in /etc/ansible/ansible.cfg , so that the SSH client stops verifying the remote host SSH signatures. Otherwise the host signatures should be listed in your known_hosts file.
The following lines in /etc/ansible/hosts list your GSM gateways:
[yeastar] gsm01 ansible_host=192.168.99.66 ansible_ssh_pass=kljckhjeswvdfesv gsm02 ansible_host=192.168.99.67 ansible_ssh_pass=dmnckjfvrever gsm03 ansible_host=192.168.99.68 ansible_ssh_pass=dcmnkljdfhfe [yeastar:vars] ansible_user=root ansible_port=8022If you use the same root password on all devices, the password variable can be moved to the group variables.
Ansible uses SFTP for ad-hoc commands, and SFTP is not available on Yestar gateways. But the raw module works just fine, and resetting a GSM module can now be done with a simple command from your management server:
ansible gsm03 -m raw -a '/bin/asterisk -rx "gsm power reset 2"'

Hardware acceleration for video codecs is almost mandatory.
VP9 is getting a performance boostThere are three things that keep VP8 in the game when compared to H.264:
With VP9, the main worry was that it will be left behind and not get the love and attention from chipset vendors – leading it to the same fate as VP8 – abysmal, if any, hardware acceleration support. It is probably why Google went to great lengths to make it running on YouTube so soon and is publicizing its stats all the time.
This worry is now rather behind us. Recent signs show some serious adoption from the companies that we should really care about:
#1 – ARMMobile=ARM
Without checking stats, I’d say that 99% or more of all smartphones sold in the past 5 years are based on ARM.
If and when ARM decides to support a feature directly, that brings said feature very close towards world domination in future smartpones.
Which is somewhat what happened last week – ARM announced its Mali Egil Video Processor with VP9 acceleration.
Here’s a deck they shared:
ARM Mali "Egil" technical preview from Phil Hughes
Being farther away from chipsets than I were 5 years ago, it is hard for me to say if this is an integral part of an ARM processor, but I believe that it isn’t. It is an add-on component that takes care of video processing that chipset vendors add next to their ARM core. They can source the design from ARM or other suppliers – or they can develop their own.
Not sure how popular the ARM alternative is for video processing, but they have the advantage of being the first alternative for any chipset vendor (hell – they already source the ARM core itself, so why not bundle?). Which also means every other vendor needs to match up to their feature set – and improve on it.
Now that VP9 encode/decode capabilities are front and center in the ARM Mali Egil, it has become a mandatory checkmark for everyone else as well.
#2 – IntelIf ARM is the king of mobile, then Intel rules the desktop.
As with ARM, I haven’t been following up on Intel CPU acceleration lately. And as with ARM, it was Fippo who got my attention with this link here: the new Intel Media SDK.
For those who don’t know, Intel is providing several interesting software packages that make direct use of its chipset capabilities. Especially when it comes to optimizing different types of workloads. The Intel IPP and Media SDKs handle media related processing, and are quite popular by low level developers who need access to such facilities.
From the release page itself:
With this release we are happy to announce new full hardware accelerated support for HEVC and VP9.
So… HEVC (=H.265) has encode and decode while VP9 only has decode support.
Probably because HEVC has been in the works for a lot longer than VP9, but there’s hope still.
#3 – Alliance of Open MediaThe Alliance of Open Media. I’ve published a recent update on the alliance.
Intel was there from the start. The recent additions include ARM, AMD and NVIDIA.
I am sure additional chipset vendors will be joining in the coming months – there seems to be a ramp up in memerships there, with Ateme and Adobe added to their logos just last week.
While the alliance is about what comes after VP9, it is easy to see how these vendors may sway to using VP9 in the interim.
The FutureThe future is most definitely one of royalty free video codecs. We’ve got there with voice, now that we have OPUS (though Speex and SILK were there before to pave the way). We will get there with video as well.
Coding technologies need to be accessible and available to everyone – freely – if we are to achieve Benedict Evans’ latest claims: Video is the new HTML. But for that, I’ll need another post.

Our good old Samsung Galaxy Tab 3 7.0 Kids Tablet has finally died after over 3 years of everyday heavy use, so I needed a new solution. So far, here is the best combination that I could find:
This silicon case for Samsung Galaxy TAB A 7″ SM-T280 is a solid and protective piece, and it allows the kids hold the tablet with their little hands without slipping off. It also works as a stand, so it’s very convenient for watching videos.
The Samsung Galaxy Tab A (7″, 8GB, Metallic Black) fits perfectly into the protective case. The tablet is coming with preinstalled “Kids Mode” application, which is pretty neat, but very restrictive: the kid can watch only the videos on SD card that you mark as safe, and YouTube is not available. You can install kid-safe YouTube wrappers from the Play market, but it’s a bit too much hassle to my taste.
So, instead of the Samsung Kids Mode, I installed Kids Place by kiddoware. With a little payment, you get a good child protection mode, and you can enable YouTube directly on the child screen. The payment is also transferable to other devices under your account.
Also, this portable Bluetooth speaker works as a stand for a tablet, and it produces a much better sound than the tablet’s own speaker. Unfortunately the silicon case is too thick for this stand, but it’s a minor issue, and the speaker can easily be placed behind the tablet.
Phosfluorescently utilize future-proof scenarios whereas timely leadership skills. Seamlessly administrate maintainable quality vectors whereas proactive mindshare.
Dramatically plagiarize visionary internal or "organic" sources via process-centric. Compellingly exploit worldwide communities for high standards in growth strategies.
Wow, this most certainly is a great a theme.
