* When media elements are connected, it can be the case that the
* encoding required in both input and output pads is not the same, and

* Provides the functionality to store contents. The recorder can store

* from another MediaElement (i.e. the source), and stores it in the
* designated location.
*
*
* The following information has to be provided In order to create a
* RecorderEndpoint, and can’t be changed afterwards:
*
* -
* URI of the resource where media will be stored. Following schemas
* are supported:
*
* -
* Files: mounted in the local file system.
*
* - file://
*
* -
* HTTP: Requires the server to support method PUT
*
* -
* http(s)://
/path/to/file
*
* -
* http(s)://username:password@
/path/to/file
*
*
*
*
*
* -
* Relative URIs (with no schema) are supported. They are completed
* prepending a default URI defined by property defaultPath. This
* property allows using relative paths instead of absolute paths. If
*
* -
* The media profile used to store the file. This will determine the
* encoding. See below for more details about media profile
*
* -
* Optionally, the user can select if the endpoint will stop
* processing once the EndOfStream event is detected.
*
*
*
*
* RecorderEndpoint requires access to the resource where stream is going
*
*
* The media profile is quite an important parameter, as it will
* determine whether there is a transcodification or not. If the input
* stream codec if not compatible with the selected media profile, the
* media will be transcoded into a suitable format, before arriving at
* the RecorderEndpoint's sink pad. This will result in a higher CPU load
*
* - WEBM: No transcodification will take place.
* - MP4: The media server will have to transcode the media received
* from VP8 to H264. This will raise the CPU load in the system.
*
*
*
* Recording will start as soon as the user invokes the record method.
* The recorder will then store, in the location indicated, the media
* that the source is sending to the endpoint’s sink. If no media is
* being received, or no endpoint has been connected, then the
* destination will be empty. The recorder starts storing information
* into the file as soon as it gets it.
*
*

* Control interface for Kurento WebRTC endpoint.
*
*
* This endpoint is one side of a peer-to-peer WebRTC communication,
* being the other peer a WebRTC capable browser -using the
* RTCPeerConnection API-, a native WebRTC app or even another Kurento
* Media Server.
*
*
* In order to establish a WebRTC communication, peers engage in an SDP
* negotiation process, where one of the peers (the offerer) sends an
* offer, while the other peer (the offeree) responds with an answer.
* This endpoint can function in both situations
*
* -
* As offerer: The negotiation process is initiated by the media
* server
*
* - KMS generates the SDP offer through the
*
generateOffer method. This offer must then
* be sent to the remote peer (the offeree) through the signaling
* channel, for processing.
* - The remote peer process the offer, and generates an
* answer to this offer. The answer is sent
* back to the media server.
* - Upon receiving the answer, the endpoint must invoke
* the
processAnswer method.
*
*
* -
* As offeree: The negotiation process is initiated by the remote
* peer
*
* - The remote peer, acting as offerer, generates an SDP
* offer and sends it to the WebRTC endpoint in
* Kurento.
* - The endpoint will process the offer invoking the
*
processOffer method. The result of this method will
* - The SDP answer must be sent back to the offerer, so
* it can be processed.
*
*
*
*
*
* SDPs are sent without ICE candidates, following the Trickle ICE
* optimization. Once the SDP negotiation is completed, both peers
* proceed with the ICE discovery process, intended to set up a
* bidirectional media connection. During this process, each peer
*
* - Discovers ICE candidates for itself, containing pairs of IPs and
*
- ICE candidates are sent via the signaling channel as they are
* discovered, to the remote peer for probing.
* - ICE connectivity checks are run as soon as the new candidate
* description, from the remote peer, is available.
*
* Once a suitable pair of candidates (one for each peer) is discovered,
* the media session can start. The harvesting process in Kurento, begins
*
*
* It's important to keep in mind that WebRTC connection is an
* asynchronous process, when designing interactions between different
* MediaElements. For example, it would be pointless to start recording
* before media is flowing. In order to be notified of state changes, the
*
* -
*
IceComponentStateChange: This event informs only
* about changes in the ICE connection state. Possible values are:
*
* DISCONNECTED: No activity scheduledGATHERING: Gathering local candidatesCONNECTING: Establishing connectivityCONNECTED: At least one working candidate
* pairREADY: ICE concluded, candidate pair selection
* is now finalFAILED: Connectivity checks have been
* completed, but media connection was not established
* The transitions between states are covered in RFC5245.
* It could be said that it's network-only, as it only takes into
* account the state of the network connection, ignoring other higher
*
* -
*
IceCandidateFound: Raised when a new candidate is
* discovered. ICE candidates must be sent to the remote peer of the
* connection. Failing to do so for some or all of the candidates
* might render the connection unusable.
*
* -
*
IceGatheringDone: Raised when the ICE harvesting
* process is completed. This means that all candidates have already
* been discovered.
*
* -
*
NewCandidatePairSelected: Raised when a new ICE
* candidate pair gets selected. The pair contains both local and
* remote candidates being used for a component. This event can be
* raised during a media session, if a new pair of candidates with
* higher priority in the link are found.
*
* -
*
DataChannelOpen: Raised when a data channel is open.
*
* -
*
DataChannelClose: Raised when a data channel is
* closed.
*
*
*
*
* Registering to any of above events requires the application to provide
*
*
* Flow control and congestion management is one of the most important
* features of WebRTC. WebRTC connections start with the lowest bandwidth
*
*
* The default bandwidth range of the endpoint is 100kbps-500kbps, but it
*
* -
* Input bandwidth control mechanism: Configuration interval used to
* inform remote peer the range of bitrates that can be pushed into
* this WebRtcEndpoint object.
*
* -
* setMin/MaxVideoRecvBandwidth: sets Min/Max bitrate limits
* expected for received video stream.
*
* -
* setMin/MaxAudioRecvBandwidth: sets Min/Max bitrate limits
* expected for received audio stream.
*
*
* Max values are announced in the SDP, while min values are set to
* limit the lower value of REMB packages. It follows that min values
*
* -
* Output bandwidth control mechanism: Configuration interval used to
*
* -
* setMin/MaxVideoSendBandwidth: sets Min/Max bitrate limits for
*
*
*
*
* All bandwidth control parameters must be changed before the SDP
* negotiation takes place, and can't be changed afterwards.
*
*
* DataChannels allow other media elements that make use of the DataPad,
* to send arbitrary data. For instance, if there is a filter that
* publishes event information, it'll be sent to the remote peer through
* the channel. There is no API available for programmers to make use of
* this feature in the WebRtcElement. DataChannels can be configured to
* provide the following:
*
* -
* Reliable or partially reliable delivery of sent messages
*
* -
* In-order or out-of-order delivery of sent messages
*
*
* Unreliable, out-of-order delivery is equivalent to raw UDP semantics.
* The message may make it, or it may not, and order is not important.
* However, the channel can be configured to be partially reliable
*
*
* The possibility to create DataChannels in a WebRtcEndpoint must be
* explicitly enabled when creating the endpoint, as this feature is
* disabled by default. If this is the case, they can be created invoking
*
* -
*
label: assigns a label to the DataChannel. This can
* help identify each possible channel separately.
*
* -
*
ordered: specifies if the DataChannel guarantees
* order, which is the default mode. If maxPacketLifetime and
* maxRetransmits have not been set, this enables reliable mode.
*
* -
*
maxPacketLifeTime: The time window in milliseconds,
* during which transmissions and retransmissions may take place in
* unreliable mode. This forces unreliable mode, even if
* ordered has been activated.
*
* -
*
maxRetransmits: maximum number of retransmissions
* that are attempted in unreliable mode. This forces unreliable
* mode, even if ordered has been activated.

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

* otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
*
* @name autoInject
* @static
* @memberOf module:ControlFlow
* @method
* @see [async.auto]{@link module:ControlFlow.auto}
* @category Control Flow
* @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
* the form 'func([dependencies...], callback). The object's key of a property
* serves as the name of the task defined by that property, i.e. can be used
* when specifying requirements for other tasks.
* * The `callback` parameter is a `callback(err, result)` which must be called
* when finished, passing an `error` (which can be `null`) and the result of
* the function's execution. The remaining parameters name other tasks on
* which the task is dependent, and the results from those tasks are the
* arguments of those parameters.
* @param {Function} [callback] - An optional callback which is called when all
* the tasks have been completed. It receives the `err` argument if any `tasks`
* pass an error to their callback, and a `results` object with any completed
* task results, similar to `auto`.
* @example
*
* // The example from `auto` can be rewritten as follows:
* async.autoInject({
* get_data: function(callback) {
* // async code to get some data
* callback(null, 'data', 'converted to array');
* },
* make_folder: function(callback) {
* // async code to create a directory to store a file in
* // this is run at the same time as getting the data
* callback(null, 'folder');
* },
* write_file: function(get_data, make_folder, callback) {
* // once there is some data and the directory exists,
* // write the data to a file in the directory
* callback(null, 'filename');
* },
* email_link: function(write_file, callback) {
* // once the file is written let's email a link to it...
* // write_file contains the filename returned by write_file.
* callback(null, {'file':write_file, 'email':'[email protected]'});
* }
* }, function(err, results) {
* console.log('err = ', err);
* console.log('email_link = ', results.email_link);
* });
*
* // If you are using a JS minifier that mangles parameter names, `autoInject`
* // will not work with plain functions, since the parameter names will be
* // collapsed to a single letter identifier. To work around this, you can
* // explicitly specify the names of the parameters your task function needs
* // in an array, similar to Angular.js dependency injection.
*
* // This still has an advantage over plain `auto`, since the results a task
* // depends on are still spread into arguments.
* async.autoInject({
* //...
* write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {
* callback(null, 'filename');
* }],
* email_link: ['write_file', function(write_file, callback) {
* callback(null, {'file':write_file, 'email':'[email protected]'});
* }]
* //...
* }, function(err, results) {
* console.log('err = ', err);
* console.log('email_link = ', results.email_link);

/**
* An "async function" in the context of Async is an asynchronous function with
* a variable number of parameters, with the final parameter being a callback.
* (`function (arg1, arg2, ..., callback) {}`)
* The final callback is of the form `callback(err, results...)`, which must be
* called once the function is completed. The callback should be called with a
* Error as its first argument to signal that an error occurred.
* Otherwise, if no error occurred, it should be called with `null` as the first
* argument, and any additional `result` arguments that may apply, to signal
* successful completion.
* The callback must be called exactly once, ideally on a later tick of the
* JavaScript event loop.
*
* This type of function is also referred to as a "Node-style async function",
* or a "continuation passing-style function" (CPS). Most of the methods of this
* library are themselves CPS/Node-style async functions, or functions that
* return CPS/Node-style async functions.
*
* Wherever we accept a Node-style async function, we also directly accept an
* [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
* In this case, the `async` function will not be passed a final callback
* argument, and any thrown error will be used as the `err` argument of the
* implicit callback, and the return value will be used as the `result` value.
* (i.e. a `rejected` of the returned Promise becomes the `err` callback
* argument, and a `resolved` value becomes the `result`.)
*
* Note, due to JavaScript limitations, we can only detect native `async`
* functions and not transpilied implementations.
* Your environment must have `async`/`await` support for this to work.
* (e.g. Node > v7.6, or a recent version of a modern browser).
* If you are using `async` functions through a transpiler (e.g. Babel), you
* must still wrap the function with [asyncify]{@link module:Utils.asyncify},
* because the `async function` will be compiled to an ordinary function that
* returns a promise.

/**
`Promise.all` accepts an array of promises, and returns a new promise which
is fulfilled with an array of fulfillment values for the passed promises, or
rejected with the reason of the first passed promise to be rejected. It casts all
elements of the passed iterable to promises as it runs this algorithm.
Example:
```javascript
let promise1 = resolve(1);
let promise2 = resolve(2);
let promise3 = resolve(3);
let promises = [ promise1, promise2, promise3 ];
Promise.all(promises).then(function(array){
// The array here would be [ 1, 2, 3 ];
});
```
If any of the `promises` given to `all` are rejected, the first promise
that is rejected will be given as an argument to the returned promises's
rejection handler. For example:
Example:
```javascript
let promise1 = resolve(1);
let promise2 = reject(new Error("2"));
let promise3 = reject(new Error("3"));
let promises = [ promise1, promise2, promise3 ];
Promise.all(promises).then(function(array){
// Code here never runs because there are rejected promises!
}, function(error) {
// error.message === "2"
});
```

`Promise.race` returns a new promise which is settled in the same way as the
first passed promise to settle.
Example:

}, 200);
});
let promise2 = new Promise(function(resolve, reject){
setTimeout(function(){
resolve('promise 2');
}, 100);
});
Promise.race([promise1, promise2]).then(function(result){
// result === 'promise 2' because it was resolved before promise1
// was resolved.
});
```
`Promise.race` is deterministic in that only the state of the first
settled promise matters. For example, even if other promises given to the
`promises` array argument are resolved, but the first settled promise has
become rejected before the other promises became fulfilled, the returned
promise will become rejected:
```javascript
let promise1 = new Promise(function(resolve, reject){
setTimeout(function(){
resolve('promise 1');
}, 200);
});
let promise2 = new Promise(function(resolve, reject){
setTimeout(function(){
reject(new Error('promise 2'));

});
Promise.race([promise1, promise2]).then(function(result){
// Code here never runs
}, function(reason){
// reason.message === 'promise 2' because promise 2 became rejected before
// promise 1 became fulfilled
});
```

```javascript

/**
Promise objects represent the eventual result of an asynchronous operation. The
primary way of interacting with a promise is through its `then` method, which
registers callbacks to receive either a promise's eventual value or the reason
why the promise cannot be fulfilled.
Terminology
-----------
- `promise` is an object or function with a `then` method whose behavior conforms to this specification.
- `thenable` is an object or function that defines a `then` method.
- `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
- `exception` is a value that is thrown using the throw statement.
- `reason` is a value that indicates why a promise was rejected.
- `settled` the final resting state of a promise, fulfilled or rejected.
A promise can be in one of three states: pending, fulfilled, or rejected.
Promises that are fulfilled have a fulfillment value and are in the fulfilled
state. Promises that are rejected have a rejection reason and are in the
rejected state. A fulfillment value is never a thenable.
Promises can also be said to *resolve* a value. If this value is also a
promise, then the original promise's settled state will match the value's
settled state. So a promise that *resolves* a promise that rejects will
itself reject, and a promise that *resolves* a promise that fulfills will
itself fulfill.
Basic Usage:
------------
```js
let promise = new Promise(function(resolve, reject) {
// on success
resolve(value);
// on failure
reject(reason);
});
promise.then(function(value) {
// on fulfillment
}, function(reason) {
// on rejection
});
```
Advanced Usage:
---------------
Promises shine when abstracting away asynchronous interactions such as
`XMLHttpRequest`s.
```js
function getJSON(url) {
return new Promise(function(resolve, reject){
let xhr = new XMLHttpRequest();
xhr.open('GET', url);
xhr.onreadystatechange = handler;
xhr.responseType = 'json';
xhr.setRequestHeader('Accept', 'application/json');
xhr.send();
function handler() {
if (this.readyState === this.DONE) {
if (this.status === 200) {
resolve(this.response);
} else {
reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
}
}
};
});
}
getJSON('/posts.json').then(function(json) {
// on fulfillment
}, function(reason) {
// on rejection
});
```
Unlike callbacks, promises are great composable primitives.
```js
Promise.all([
getJSON('/posts'),
getJSON('/comments')
]).then(function(values){
values[0] // => postsJSON
values[1] // => commentsJSON
return values;
});
```
@class Promise
@param {Function} resolver
Useful for tooling.
@constructor
*/
var Promise$1 = function () {
function Promise(resolver) {
this[PROMISE_ID] = nextId();
this._result = this._state = undefined;
this._subscribers = [];
if (noop !== resolver) {
typeof resolver !== 'function' && needsResolver();
this instanceof Promise ? initializePromise(this, resolver) : needsNew();
}
}
/**
The primary way of interacting with a promise is through its `then` method,
which registers callbacks to receive either a promise's eventual value or the
reason why the promise cannot be fulfilled.
```js
findUser().then(function(user){
// user is available
}, function(reason){
// user is unavailable, and you are given the reason why
});
```
Chaining
--------
The return value of `then` is itself a promise. This second, 'downstream'
promise is resolved with the return value of the first promise's fulfillment
or rejection handler, or rejected if the handler throws an exception.
```js
findUser().then(function (user) {
return user.name;
}, function (reason) {
return 'default name';
}).then(function (userName) {
// If `findUser` fulfilled, `userName` will be the user's name, otherwise it
// will be `'default name'`
});
findUser().then(function (user) {
throw new Error('Found user, but still unhappy');
}, function (reason) {
throw new Error('`findUser` rejected and we're unhappy');
}).then(function (value) {
// never reached
}, function (reason) {
// if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
// If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
});
```
If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
```js
findUser().then(function (user) {
throw new PedagogicalException('Upstream error');
}).then(function (value) {
// never reached
}).then(function (value) {
// never reached
}, function (reason) {
// The `PedgagocialException` is propagated all the way down to here
});
```
Assimilation
------------
Sometimes the value you want to propagate to a downstream promise can only be
retrieved asynchronously. This can be achieved by returning a promise in the
fulfillment or rejection handler. The downstream promise will then be pending
until the returned promise is settled. This is called *assimilation*.
```js
findUser().then(function (user) {
return findCommentsByAuthor(user);
}).then(function (comments) {
// The user's comments are now available
});
```
If the assimliated promise rejects, then the downstream promise will also reject.
```js
findUser().then(function (user) {
return findCommentsByAuthor(user);
}).then(function (comments) {
// If `findCommentsByAuthor` fulfills, we'll have the value here
}, function (reason) {
// If `findCommentsByAuthor` rejects, we'll have the reason here
});
```
Simple Example
--------------
Synchronous Example
```javascript
let result;
try {
result = findResult();
// success
} catch(reason) {
// failure
}
```
Errback Example
```js
findResult(function(result, err){
if (err) {
// failure
} else {
// success
}
});
```
Promise Example;
```javascript
findResult().then(function(result){
// success
}, function(reason){
// failure
});
```
Advanced Example
--------------
Synchronous Example
```javascript
let author, books;
try {
author = findAuthor();
books = findBooksByAuthor(author);
// success
} catch(reason) {
// failure
}
```
Errback Example
```js
function foundBooks(books) {
}
function failure(reason) {
}
findAuthor(function(author, err){
if (err) {
failure(err);
// failure
} else {
try {
findBoooksByAuthor(author, function(books, err) {
if (err) {
failure(err);
} else {
try {
foundBooks(books);
} catch(reason) {
failure(reason);
}
}
});
} catch(error) {
failure(err);
}

}
});
```
