Version 3.0. recording

[Artem_M_]

Hello. We tryed to start recording in current version. You told us that it should work in not mix mode, but we still have errors.

We created room:

{
	"name": "b9f24379544e8033e9cd916cc0bbc2b6",
	"mode": "hybrid",
	"publishLimit": -1,
	"userLimit": -1,
	"mediaMixing": {
		"video": {
			"avCoordinated": 0,
			"maxInput": 16,
			"resolution": "vga",
			"multistreaming": 0,
			"bitrate": 0,
			"bkColor": "black",
			"layout": {
				"base": "fluid",
				"custom": []
			}
		},
		"audio": null
	},
	"enableMixing": 0,
	"_id": ObjectId("56bbb96eaedbf07233722fe7")
}

We started recorder after recieving stream-added:

var nativeStreamId = stream.id();
conference.startRecorder({
	videoStreamId: nativeStreamId,
	audioStreamId: nativeStreamId,
	//videoCodec: 'h264',//'vp8'/'h264',
	//audioCodec: 'pcmu',//'pcmu'/'opus',
	//recorderId: 'zzzzzz'
}, function (file) {
//conference.startRecorder({}, function (file) {
	console.log('Stream recording with recorder ID: ', file.recorderId);
}, function (err) {
	L.Logger.error('Media recorder failed:', err);
}); 

In cconfiguration(in attachment with logs) we use:

// If undefined, the path will be /tmp/
config.erizoController.recording_path = undefined; // default value: undefined

// If true and the maxProcesses allows, the mixer will be run in a dedicated process.
config.erizoController.outOfProcessMixer = false;

config.erizoAgent = {};

config.erizoAgent.interval_time_keepAlive = 1000; // default value: 1000
// config.erizoAgent.networkInterface = 'eth0' // default value: undefined

// Max processes that ErizoAgent can run
config.erizoAgent.maxProcesses = 13; // default value: 13
// Number of precesses that ErizoAgent runs when it starts. Always lower than or equals to maxProcesses.
config.erizoAgent.prerunProcesses = 1; // default value: 2

We recieve errors:

ERROR: Media recorder failed: Error in start recording: error - in browser

ERROR: ErizoJSController - Failed adding ExternalOutput to /#at9skX6eC2u7j9dpAAAA and /#at9skX6eC2u7j9dpAAAA with url /tmp/room56bbb96eaedbf07233722fe7_2016021102324842.mkv - in logs

Hi Artem,

I observed that "Room  xxx1  does not exist" pops from the log, anything goes wrong there?

And what is the Chrome version you're using?

Thanks!

That log info - is dump requests from some other client side. It's not influence on anything. Helpful information in other log files

Hello Chunbo,

i was able to get recording to work in latest Version 3 update 2.

But there is a problem with audio when using the default room (Mix enabled)

1. When I have single person that persons voice is recorded.

2. When 2 persons in conference -- the initial person audio is not record only 2nd person audio is recorded

3. When 3 persons in conference, still only one person's audio is recorded other 2 person's audio are not recorded

Code details i have invoked at trySubscribeStream 

var nativeStreamId = stream.id();

conference.startRecorder({
                videoStreamId: nativeStreamId,
                audioStreamId: nativeStreamId,

Is there anything i have missed?

if i grep for error in logs dir i get below is this the cause of this audio issue?

Hi Sergey,

Our QA engineers have tried to reproduce the issue you described but it seems not reproducible to us…

Could you check whether you have the access permission to write data to /tmp folder?

Thanks!
