## `options`
RecordRTC requires a second parameter named as `options` or `configuration` or `hints` or `preferences`:
```javascript
var options = {
recorderType: MediaStreamRecorder,
mimeType: 'video/webm\;codecs=vp9'
};
var recordRTC = RecordRTC(stream, options);
```
* `type` accepts `video` or `audio` or `canvas` or `gif`
* `mimeType` accepts [all these values](https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder/mimeType)
* `recorderType` accepts `MediaStreamRecorder` or `StereoAudioRecorder` or `WhammyRecorder` or `GifRecorder` or any recorder type from [this page](https://github.com/muaz-khan/RecordRTC/tree/master/dev)
* `timeSlice` accepts numbers in milliseconds; use this to force intervals-based blobs
* `checkForInactiveTracks` accepts `true` or `false`; use this to disable default inactive-stream-checker functions
* `onTimeStamp` it is a function that is called-back by the MediaStreamRecorder; `timeSlice` parameter is required for this function
* `bitsPerSecond` accepts numbers in bits; applies both to audio and video tracks
* `audioBitsPerSecond` accepts numbers in bits; applies only to audio tracks
* `videoBitsPerSecond` accepts numbers in bits; applies only to video tracks
* `disableLogs` accepts `true` or `false`; use this to disable console logs
* `frameInterval` accepts numbers in milliseconds; use this with MultiStreamRecorder, CanvasRecorder and WhammyRecorder
* `previewStream` it is a function that is called-back by the MultiStreamRecorder
* `video` accepts object similar to this: `{width: 320, height: 240}`; pass this parameter for MultiStreamRecorder, CanvasRecorder and WhammyRecorder
* `canvas` accepts object similar to this: `{width: 320, height: 240}`; pass this parameter for MultiStreamRecorder, CanvasRecorder and WhammyRecorder
* `sampleRate` used only by the StereoAudioRecorder
* `bufferSize` used only by the StereoAudioRecorder
* `numberOfAudioChannels` used only by the StereoAudioRecorder
## Record Multiple Videos
You can record 4 parallel videos/streams (**WebRTC Conference**):
Demos:
1. [Record all your cameras](https://github.com/muaz-khan/RecordRTC/blob/master/simple-demos/multi-cameras-recording.html)
2. [Record screen as well as your video!](https://github.com/muaz-khan/RecordRTC/blob/master/simple-demos/video-plus-screen-recording.html)
You can record many videos/streams in single WebM/Mp4 file (**WebRTC Conference Recording**):
```javascript

@@ -274,12 +372,77 @@ var arrayOfStreams = [localStream, remoteStream1, remoteStream2, remoteStream3];

> This simply means that: **You can record 4 users video conference in single WebM or Mp4 container!**
Note: This feature still requires `chrome://flags/#enable-experimental-web-platform-features` flag on Chrome.
Points:
1. Instead of passing single `MediaStream`, you are passing array of `MediaStreams`
2. You are keeping the `type=video`
3. You will get single webm or mp4 according to your `mimeType`
2. You will get single webm or mp4 according to your `mimeType`
`MultiStreamRecorder.js` supports two extra methods:
1. `addStreams`
2. `resetVideoStreams`
```javascript
var msRecorder = recorder.getInternalRecorder();
if (msRecorder instanceof MultiStreamRecorder) {
msRecorder.addStreams([newAudioStream]);
msRecorder.resetVideoStreams([screenStream]);
}
```
Usecases:
1. You can add more audio and/or video streams during live recording (using `addStreams` method)
2. You can reset/remove/replace old videos using `resetVideoStreams`
`resetVideoStreams` can be used to recorded screenStream in full-screen mode e.g.
```javascript
if (yourScreen.isScreen === true) {
yourScreen.fullcanvas = true;
yourScreen.width = window.screen.width;
yourScreen.height = window.screen.height;
// now it will record all audios + only_this_screen
internalRecorder.resetVideoStreams([yourScreen]);
}
```
As soon as [screen is stopped](https://www.webrtc-experiment.com/webrtcpedia/#stream-ended-listener):
```javascript
addStreamStopListener(yourScreen, function() {
var cameraStreams = getSingleOrMultipleCameraStreams();
// now it will record all audios + all_your_cameras
internalRecorder.resetVideoStreams(cameraStreams);
});
```
## `getInternalRecorder`
You can get access to internal recorders e.g. MultiStreamRecorder, MediaStreamRecorder, StereoAudioRecorder, WhammyRecorder etc.
> Use `getInternalRecorder` only after `startRecording`. It may return `NULL` according to RecordRTC current state.
```javascript
// if RecordRTC recording in-progress
if (recorder.state === 'recording') {
// get MediaStreamRecorder
var msRecorder = recorder.getInternalRecorder();
// always check for NULL or verify the recorder type
if (msRecorder instanceof MultiStreamRecorder) {
// it is NOT NULL
// also it is MultiStreamRecorder instance
// now we can use these extra methods
msRecorder.addStreams([newAudioStream]);
msRecorder.resetVideoStreams([screenStream]);
}
}
```
Internal recorders can add extra methods. Same as MultiStreamRecorder which is supporting two extra methods:
1. `addStreams`
2. `resetVideoStreams`

# Travis Failed?
Steps to fix it (for your private projects only):
Modify `package.json` and search this line:
```json
{
"test": "./node_modules/.bin/protractor test/browserstack.config.js"
}
```
Replace it with (i.e. ignore all "test"):
```json
{
"test": "node npm-test.js"
}
```
Why? Reason is this file: `test/browserstack.config.js`
```javascript
'browserstack.user': process.env.BROWSERSTACK_USERNAME,
'browserstack.key': process.env.BROWSERSTACK_KEY,
```
**Your travis do NOT have these environment variables. That's why your travis builds fails.**
More info: https://github.com/muaz-khan/RecordRTC/pull/283#issuecomment-308757116
