I can stream Netflix just fine when I play it using my Chrome browser. But, when I try to play Netflix using Safari (version 10.0), I get one or two frames of video, and then a black screen. I still have all of the controls and slider and I still get sound, but the video is just a black screen.
I just now tried it again using Safari, and got code S7363-1260-48444350 when trying to play a video. The code referred to an incompatible monitor. I tried again, and got the same issue as before, where I get a few frames of the video, and then the video goes black, but I can hear the audio and I still have control of the playback (e.g., play/pause, volume, etc.).
When I unplugged my external monitors and used only the laptop screen, the video played. So, I now know that the problem has something to do with my external monitors being connected to my laptop, even if I'm trying to play the video on my laptop screen.
Simple solution (os High Sierra) but Netflix have so far ignored my message! Forget all their solutions particularly concerning Silver Light, as that is no longer needed. This only began for me with Safari 11.0.1. I was able to connect using FireFox without issue so it had to be Safari settings.
Thanks, but I've already done an Internet search to find a solution to my problem. I've re-installed the latest version of Silverlight, and that hasn't helped. Also, Chrome works just fine with Netflix, which I think also uses Silverlight. I've also tried restarting the computer and the other typical non-specific solutions.
- I do get the display error thing (thunderbolt > VGA displays attached). Checked with develop tab if netflix works in safari 10 (don't see another version of safari in the list). However, if I select 'firefox: mac' and allow the silverlight plugin (that I just installed) then it works.
If the issue is the HTML5 player (since in older safari versions with silverlight, it does work), how do I force Netflix to use silverlight? It seems it always reverts back to HTML5, even if silverlight's installed.
I pulled this chapter together from dozens of sources that were at times somewhat contradictory. Facts on the ground change over time and depend who is telling the story and what audience they're addressing. I tried to create as coherent a narrative as I could. If there are any errors I'd be more than happy to fix them. Keep in mind this article is not a technical deep dive. It's a big picture type article. For example, I don't mention the word microservice even once :-)
Given our discussion in the What is Cloud Computing? chapter, you might expect Netflix to serve video using AWS. Press play in a Netflix application and video stored in S3 would be streamed from S3, over the internet, directly to your device.
Another relevant factoid is Netflix is subscription based. Members pay Netflix monthly and can cancel at any time. When you press play to chill on Netflix, it had better work. Unhappy members unsubscribe.
The client is the user interface on any device used to browse and play Netflix videos. It could be an app on your iPhone, a website on your desktop computer, or even an app on your Smart TV. Netflix controls each and every client for each and every device.
Everything that happens before you hit play happens in the backend, which runs in AWS. That includes things like preparing all new incoming video and handling requests from all apps, websites, TVs, and other devices.
In 2007 Netflix introduced their streaming video-on-demand service that allowed subscribers to stream television series and films via the Netflix website on personal computers, or the Netflix software on a variety of supported platforms, including smartphones and tablets, digital media players, video game consoles, and smart TVs.
Netflix succeeded. Netflix certainly executed well, but they were late to the game, and that helped them. By 2007 the internet was fast enough and cheap enough to support streaming video services. That was never the case before. The addition of fast, low-cost mobile bandwidth and the introduction of powerful mobile devices like smart phones and tablets, has made it easier and cheaper for anyone to stream video at any time from anywhere. Timing is everything.
Building out a datacenter is a lot of work. Ordering equipment takes a long time. Installing and getting all the equipment working takes a long time. And as soon they got everything working they would run out of capacity, and the whole process had to start over again.
The long lead times for equipment forced Netflix to adopt what is known as a vertical scaling strategy. Netflix made big programs that ran on big computers. This approach is called building a monolith. One program did everything.
What Netflix was good at was delivering video to their members. Netflix would rather concentrate on getting better at delivering video rather than getting better at building datacenters. Building datacenters was not a competitive advantage for Netflix, delivering video is.
It took more than eight years for Netflix to complete the process of moving from their own datacenters to AWS. During that period Netflix grew its number of streaming customers eightfold. Netflix now runs on several hundred thousand EC2 instances.
The advantage of having three regions is that any one region can fail, and the other regions will step in handle all the members in the failed region. When a region fails, Netflix calls this evacuating a region.
The header image is meant to intrigue you, to draw you into selecting a video. The idea is the more compelling the header image, the more likely you are to watch a video. And the more videos you watch, the less likely you are to unsubscribe from Netflix.
The first thing Netflix does is spend a lot of time validating the video. It looks for digital artifacts, color changes, or missing frames that may have been caused by previous transcoding attempts or data transmission problems.
A pipeline is simply a series of steps data is put through to make it ready for use, much like an assembly line in a factory. More than 70 different pieces of software have a hand in creating every video.
The idea behind a CDN is simple: put video as close as possible to users by spreading computers throughout the world. When a user wants to watch a video, find the nearest computer with the video on it and stream to the device from there.
In 2007, when Netflix debuted its new streaming service, it had 36 million members in 50 countries, watching more than a billion hours of video each month, streaming multiple terabits of content per second.
At the same time, Netflix was also devoting a lot of effort into all the AWS services we talked about earlier. Netflix calls the services in AWS its control plane. Control plane is a telecommunications term identifying the part of the system that controls everything else. In your body, your brain is the control plane; it controls everything else.
In 2011, Netflix realized at its scale it needed a dedicated CDN solution to maximize network efficiency. Video distribution is a core competency for Netflix and could be a huge competitive advantage.
The number of OCAs on a site depends on how reliable Netflix wants the site to be, the amount of Netflix traffic (bandwidth) that is delivered from that site, and the percentage of traffic a site allows to be streamed.
Within a location, a popular video like House of Cards is copied to many different OCAs. The more popular a video, the more servers it will be copied to. Why? If there was only one copy of a very popular video, streaming the video to members would overwhelm the server. As they say, many hands make light work.
Right now, up to 100% of Netflix content is being served from within ISP networks. This reduces costs by relieving internet congestion for ISPs. At the same time, Netflix members experience a high-quality viewing experience. And network performance improves for everyone.
What may not be immediately obvious is that the OCAs are independent of each other. OCAs act as self-sufficient video-serving archipelagos. Members streaming from one OCA are not affected when other OCAs fail.
As hinted, WD TV Live Streaming Media Player (Gen 3) is the version with Netflix support. The current WDTV Media Player product hardware is practically identical (just no LIVE on the front panel) but software is different - Netflix is one of the features removed.
The device does not have the Netflix copy protection chip in it so never can have Netflix capability. Ther are inexpensive ways to get Netflix on your TV. A Chromecast on TV controlled by a phone or tablet with the Netflix app can do the job.
The Roku was the original Netflix player and the first. one was primarily a Netflix player . I have had the first three players and have stayed with the last one,Roku 2 since the newer ones had no great features I needed. Roku was first and best player and the WDTV was not a good UI and never use it for Netflix,used just as a media player.
Cold boot time is also as much as three or four minutes and even warm boots are sometimes a minute long. Leaving the device running often results in low memory errors or videos stuttering or failing to play. Now about half of my MKVs which used to play smoothly no longer play at all.
I still have email from WD support on my WDTV Live unit. It explains how to activate Miricast which I did and as promised a large number of otherwise unseen apps showed up to the right of the screen. But; the promised NETFLIX app was not included.
