If .load() is called, we don't know what the new source will be because of the asynchronous nature of the resource selection algorithm. However, we can know if the src attribute is set on the video element because that's what will be chosen. So, set the src property on the event object to be the src attribute or be the empty string. This matches how currentSrc works where it is an empty string when no source is set. So, when sourceset is triggered and src is "" in the event object, it means that the source is changing.
In addition, we're going to be releasing sourceset as an experimental feature so we could improve the API and make changes in minor releases.
Add setFormatTime for Video.js to allow users to change the time format. Example usage:
```js
videojs.setFormatTime((seconds, guide) => `${seconds}, ${guide}`));
```
Add resetFormatTime to reset the time format to the default.
Fixes#2931
The option for the player techCanOverridePoster is introduced in this commit. It allows techs to update the post whenever they like. isPosterFromTech_ is introduced as a private player field in order to track when a poster was set by a tech. This allows us to clear the poster whenever the tech is disposed of by the player.
Additionally, attempting to set the same poster more than once will have no effect / no changes will be made, since the poster is the same. This was done in order to stop triggering multiple posterchange events when calling player.poster(aPoster) with techCanOverridePoster set to true.
When a tech is disposed and a poster was set by it, unset the poster.
Pass a `canOverridePoster` option to techs to know whether techCanOverridePoster was set.
Fixes#4910.
Trigger a sourceset event whenever the source is set in the Html5 tech, including initial source. We override the video element's src and setAttribute methods so that we can trigger the sourceset event when people change the src with both the video element and our API methods.
The event object for sourceset will contain the src string that was provided at the time the sourceset was triggered. This is mostly important if a source is being set while a tech is changing.
A Tech has a featuresSourceset option that it can set to for sourceset handling. It can then call the helper triggerSourceset(src) to trigger the sourceset.
Middleware factories currently get run each time a source is set. Because middleware are assocated with a player, the factories should only run once per player.
This PR fixes it so that we associate a middleware instance with a middleware factory per player.
Each time a player is disposed, we will clear the cache of the middleware instances for that player.
Fixes#4677.
Use ResizeObserver when available for better and more performant resizing information, otherwise, fall back to a throttled resize event on an iframe that's the size of the player.
Allows a video.js user to disable this by setting resizeManager: false as an option since the component will not be initialized.
Add a debounce util.
This reverts #4800 (e0ed0b5) because we end up getting two playerresize events with the dimension methods now.
This will allow middleware to interact with calls to play() from the tech. This will require a method of indicating to middleware previously run that a middleware down the chain has terminated or stopped execution.
* Adds middleware mediator method that runs middleware from the player to the tech and a second time back up to the player. This category was created because play is both a setter(changes the playback state) and a getter(gets a native play promise if available). This also has the ability to tell whether a middleware has terminated before reaching the tech.
* Adds a middleware.TERMINATOR sentinel value that is available on the videojs object
* Adds play to the allowedMediators
* Adds paused to the allowedGetters
* Adds a sandbox example of a play mediator middleware
Chrome has started pausing autoplaying video elements when they are
moved in the DOM. Here we need to make sure that if the video started
autoplaying, after we move the element in the DOM we call play again.
Fixes#4720.
The core goal here is to make sure the following works in light of some middleware process that makes setting the source more async than next tick:
```js
player.src('...');
player.ready(() => player.play());
```
In fact, given this change, we should even be able to do:
```js
player.src('...');
player.play();
```
Unlike #4665, which would have clarified/changed the meaning of "ready", it remains a reflection of the tech's state and we make better use of the ability to queue things on that state and on the middleware `setSource` process.
A we retained a lot of references to DOM elements in various components. Here we clear it up. Also, make sure that we remove unused listeners as they can retain objects as well.
Update evented mixin to null out the eventBusEl_ after the component is disposed.
Add a feature for components, to tell it not to auto-initialize the evented mixin.
Re-enable the tests that were removed in #4640.
Add the ability to initialize Video.js with an element named video-js. This is because sometimes, seeing the native element is undesirable, plus, it's cool to have our own element.
Can be used just like the video embed.
IE9 is supported but only with dynamic sources as the source element can only be used inside of the video element.
We added a feature so that remote text tracks can auto-removed when a source changes. However, in 6.x we changed the source behavior to be asynchronous meaning that some text tracks were accidentally being removed when they weren't supposed to be.
For example:
```js
var player = videojs('my-player');
player.src({src: 'video.mp4', type: 'video/mp4'});
// set second arg to false so that they get auto-removed on source change
player.addRemoteTextTrack({kind: 'captions', src: 'text.vtt', srclang: 'en'}, false);
```
Now when the player loads, this captions track is actually missing because it was removed.
Instead of adding auto-removal tracks immediately to the list, wait until we've selected a source before adding them in.
Fixes#4403 and #4315.
Video.js players can accept a number of standard <video> element options (autoplay, muted, loop, etc), but not currently playsinline, which is now part of the [HTML spec](https://html.spec.whatwg.org/multipage/embedded-content.html#attr-video-playsinline). We should add it to the list of <video> attributes that can be provided to the player as options.
Prevent ClickableComponents re-adding event listeners each time enabled() is called.
* Keeps track of enabled state (this.enabled_)
* enable() doesn't do anything if the component is enabled, so the event handlers are not re-added
Fixes#4312
This adds a beforepluginsetup event as well as beforepluginsetup:$name and pluginsetup:$name events.
The drive behind this is improving the ability for people to make cross-plugin dependencies in a more robust manner.
