In this Webby Award-winning series, we challenged a video production agency to make three videos with three very different budgets.
You can try all the methods and events in this starter app on Glitch. Since Wistia embeds are initialized asynchronously, we recommend the following patterns to acquire player API handles for your videos. The first and easiest way is to push a function onto the initialization queue. The handle will be given as an argument of the callback function. There are three possible initialization events: onHasDataonEmbeddedand onReady. These names align with the hasDataembeddedand ready methods described below.
In this example, we get a handle to the video when ready becomes true:.

Note that you can push functions onto window. This will run immediately on any videos that are currently on the page. It will also be run immediately on videos injected after the page loads.
If no match is found, Wistia.HTML5 comes with elements for embedding rich media in documents — embeds a media player which supports video playback into the document. It can also be the destination for streamed media, using a MediaStream.
This article shows you how to do common tasks such as creating custom playback controls. The embeds a media player which supports video playback into the document. You can review what all the HTML features do in the article linked above; for our purposes here, the most interesting attribute is controlswhich enables the default set of playback controls. If you don't specify this, you get no playback controls:. This is not as immediately useful for video playback, but it does have advantages.
One big issue with the native browser controls is that they are different in each browser — not very good for cross-browser support! Another big issue is that the native controls in most browsers aren't very keyboard-accessible. In the next section we'll look at the basic tools we have available to do this. This interface is available to both element is used to embed sound content in documents. Let's go through an example, adding features as we go. To get started with this example, download our media-player-start.
Open the HTML index file. You'll see a number of features; the HTML is dominated by the video player and its controls:. Now open the CSS file and have a look inside. The CSS for the example is not too complicated, but we'll highlight the most interesting bits here. First of all, notice the. First of all, at the top of the CSS we use a font-face block to import a custom web font.
This is an icon font — all the characters of the alphabet equate to common icons you might want to use in an application. Icon fonts are very cool for many reasons — cutting down on HTTP requests because you don't need to download those icons as image files, great scalability, and the fact that you can use text properties to style them — like color and text-shadow.Imagine for a moment that you have a React app with a single parent component that contains many levels of child components inside of it.
Now, imagine passing data from the uppermost component all the way down to the last child component. In React data is passed top-down from one component to another through props.
The React Context API allows you to easily access data at different levels of the component tree, without having to pass data down through props. I recommend skimming through the official React documentation on Context before continuing.
And below is the same Context object inside of a functional component, using the new useContext Hook:. A Context provides both a consumer and a provider. When using the useContext Hook in React, you have to remember to pass in the whole context object, not just the consumer or provider. You create a C ontext object in React by using React. CreateContextand then passing in an initial value, like so:.
This AppContext object is what should be passed as an argument into the useContext Hook.Syria drug registration guidelines
Like this:. You can do the same, or use an existing React project. Building a music player is a fantastic example to demonstrate how the useContext Hook works because it has two child components that share the same application state:. Create a new file called MusicPlayerContext. In the code above, we create a new Context called MusicPlayerContext with no arguments passed inside of the parentheses, indicating that there is no default value for the Context.
The MusticPlayerContext. It provides the Context object for other components to consume. Rather than giving it a static value, we want to give it the ability to change its value. Therefore, we need to give our Context state. Here, we use the useState Hook to provide us state.
Most modern browsers support postMessage. Embedded players must have a viewport that is at least px by px.
If the player displays controls, it must be large enough to fully display the controls without shrinking the viewport below the minimum size. We recommend players be at least pixels wide and pixels tall. Thus, this function might create the player objects that you want to display when the page loads. The sample HTML page below creates an embedded player that will load a video, play it for six seconds, and then stop the playback.
The numbered comments in the HTML are explained in the list below the example. The Loading a video player section explains how to do so.Best looking horse rdr2 reddit
This portion of the code defines a global variable, playerwhich refers to the video player you are embedding, and the function then constructs the video player object. The onPlayerReady function will execute when the onReady event fires. In this example, the function indicates that when the video player is ready, it should begin to play.
The API will call the onPlayerStateChange function when the player's state changes, which may indicate that the player is playing, paused, finished, and so forth. The function indicates that when the player state is 1 playingthe player should play for six seconds and then call the stopVideo function to stop the video.
To call the player API methods, you must first get a reference to the player object you wish to control. You obtain the reference by creating a YT. Player object as discussed in the Getting started and Loading a video player sections of this document.
Queueing functions allow you to load and play a video, a playlist, or another list of videos. If you are using the object syntax described below to call these functions, then you can also queue or load a list of search results or a user's list of uploaded videos.
The object syntax lets you pass an object as a single parameter and to define object properties for the function arguments that you wish to set. In addition, the API may support additional functionality that the argument syntax does not support. For example, the loadVideoById function can be called in either of the following ways. Note that the object syntax supports the endSeconds property, which the argument syntax does not support.
This function loads the specified video's thumbnail and prepares the player to play the video. The cuePlaylist and loadPlaylist functions allow you to load and play a playlist or list of videos.
If you are using object syntax to call these functions, you can also queue or load a list of search results or a user's list of uploaded videos. Since the functions work differently depending on whether they are called using the argument syntax or the object syntax, both calling methods are documented below. The required playlist parameter specifies an array of YouTube video IDs. The optional index parameter specifies the index of the first video in the playlist that will play.
And it works for all other browsers I checked, but it doesn't work on FF!? What is even more interesting, that when I play video using normal YouTube play button then I can use pauseVideo method and all the others: seeking, controlling volumebut I can't use playVideo method Of course 'I am ready' is in console output.
I have no idea what I do wrong and why only FF is not working There is no JS error, and no clue Hope someone had this problem before and got it resolved!
I was having a very similar issue and was struggling with an answer. My calls to playVideo didn't seem to work. The issue was that the player was not yet available - if I just gave it a bit of time to show up, then the call worked. A more robust way to do that is to check if the player is ready. If the player is not ready, queue player.
Basically, Chrome can initialize youtube embeds even when the divs are hidden i. My solution was a variant of relic's:. So be careful not to miss on the "www". Otherwise the API will create the player object but will fail to execute methods.

After revisiting this, I found a working solution for me when using webpack or I assume any other commongJS module systemor if you find the youtube api is ready before your own JS file, was to use an interval - until youtube provides some form of promise callback:.
Make sure you are testing the page by having it actually served on the web, not just loaded locally.
