With Apple finally embracing 4K movies with the new Apple TV, you are probably wondering, “What’s the big deal?” You’ve been hearing the 4K/UHD buzzword for years now but maybe you weren’t really paying attention since it all sounded like marketing mumbo jumbo to you. A few years ago, that may have been true since there was hardly any 4K content available and those expensive state-of-the-art UHD TV sets seemed like total wastes of money. Only early tech adopters, avid videophiles and people with broad swaths of disposable income seemed interested. Fast forward to today, with cheaper 4K TV sets dropping and Apple pushing 4K content to the mainstream, it’s now safe to say that 4K has finally arrived. While 4K streaming video is nothing new – Netflix, Amazon Video, and Vudu have been offering this format for a while now – with Apple and iTunes in the mix, we’ll surely be seeing more of this UHD option getting promoted everywhere when we rent or purchase videos online. But what does all this mean and why do some video resolutions cost more than others? What are video resolutions? The three streaming formats available right now are Standard Definition (SD), High Definition (HD) and Ultra High Definition (UHD). Basically, the difference between SD, HD, or UHD formats is the number of pixels that comprise the video image. Pixels are the small dots that combine to “draw” the images you see on screen. The higher the resolution, the more pixels you have. And with more pixels, you ge...

Intro Producing the absolute best quality video you can, may not be your main focus when you first start your live streaming career. Instead of thinking about SD vs HD resolutions and framerates, you might be more interested in the social side of it. Let’s face it, it’s much more exciting to be in touch with people from all over the world than spend time obsessing over the quality of your video. Soon enough, however, you’ll notice that quality matters. So much so, in fact, that stream quality is What is video resolution? When you’re watching a video or looking at an image on a computer screen, you’re actually looking at a very large number of very small squares. We call these squares pixels. The total number of pixels that make up the video or photo frame is what we call video resolution. The general rule is that the more pixels there are – the higher the resolution is – the better the quality of the video gets. Of course, video quality is more complicated and nuanced than that. Frame rates, bitrates, and a whole host of other things on the viewer’s end affect how good your stream will look on their screen. But resolution is still very important if you want your stream to look sharp. If you wanted to provide full information about the resolution of your live stream, you’d probably write it as a big number x a slightly smaller number. 1280x720 is a way to express resolution, for example, and it means that your video’s frame is 720 pixels tall and 1280 pixels wide. A resolut...

With more major carriers offering unlimited data than ever before, the Big 4 have been forced to up the ante. That's why they're now offering high definition videos for unlimited streaming. If you've ever watched a DVD, odds are you watched it in 480p video. This level of definition is referred to as DVD quality or standard quality. The HD category starts at almost twice that definition at 720p, known as semi-HD. Full HD is over twice that level of definition at 1080p resolution. It goes up yet another tier into anything over 1080p, which is "Ultra HD" or "4k." If you're anything like most, this figures are just that - figures - with no real discernible meaning except some figures looking sharper and clearer than other figures. For most people, 480p, 780p, 1080p etc. are just letters and numbers. People understand that the higher ones equate to better videos, but they don't understand much more. That's why Wirefly is here to explain the nuances. HD Streaming vs. SD Streaming Explained Your television displays images by using pixels. Pixels are tiny dots that, together, form the cohesive picture you see on the screen. You can think of them as small, uniform puzzle or mosaic pieces that form a finished image when put together. The "p" in "1080p" stands for "pixels," and 1080 is the number of pixels in the completed image. This is true for both pictures and videos. The higher the number of pixels, the clearer the image is. The number used in resolution nomenclature actually o...

Requirements Python: Of course, you’ll need pip/setuptools: Those are needed for the installation of the Python module and its dependencies. Most systems will have these installed already, but if not, you should install it with your package manager or you can download and install pip and setuptools as described on the python3 -m pip install cffi --user PortAudio library: The libportaudio2 or similar). If you prefer, you can of course also download the sources and compile the library yourself. If you are using Mac OS X or Windows, the library will be installed automagically with pip (see “Installation” below). NumPy (optional): sounddevice.RawStream, sounddevice.RawInputStream and sounddevice.RawOutputStream use plain Python buffer objects and don’t need NumPy at all. If you need NumPy, you should install it with your package manager or use a Python distribution that already includes NumPy (see above). Installing NumPy with pip requires a compiler and several additional libraries and is therefore not recommended for beginners. python3 -m sounddevice You can use the corresponding device ID to select a desired device by assigning to sounddevice.default.device or by passing it as device argument to sounddevice.play(), sounddevice.Stream() etc. Instead of the numerical device ID, you can also use a space-separated list of case-insensitive substrings of the device name (and the host API name, if needed). See sounddevice.default.device for details. Blocking Read/Write Streams Ins...
