Adobe Media Server 5 : Error when requesting hls-live stream
1. We used flash program to publish our live stream. The actionscript code is like the following (it's better to focus to the publishStream method) :
private function setCamAndMicConfig():void
{
...
...
// --- Cam settings : where Confs is our own configuration parameters collection
_camera.setQuality(Confs.CAM_BANDWIDTH, Confs.CAM_MIN_QUALITY);
_camera.setMode(Confs.CAM_RES_W, Confs.CAM_RES_H, Confs.CAM_FPS, true);
_camera.setKeyFrameInterval( Confs.CAM_KEY_FRAME_INTERVAL );
_camera.addEventListener( StatusEvent.STATUS, cameraStatusHandler );
// --- Mic settings
_mic = Microphone.getEnhancedMicrophone();
_mic.encodeQuality = Confs.MIC_QUALITY; //10
_mic.rate = 22;
_mic.gain = 50;
_mic.setSilenceLevel( Confs.MIC_SILENCE_LVL );//default Netapsys
_mic.setUseEchoSuppression( Confs.MIC_ECHO_SPRSS );
...
...
}
public function publishStream( name:String ):void
{
...
...
_stream = new NetStream( _connection );
_stream.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
_stream.client = this;
_stream.useHardwareDecoder = true;
if (_camera != null)
{
_camera.addEventListener(ActivityEvent.ACTIVITY, activityHandler);
_stream.attachCamera(_camera);
var h264Settings:H264VideoStreamSettings = new H264VideoStreamSettings();
h264Settings.setProfileLevel( H264Profile.MAIN, H264Level.LEVEL_3_1 );//bon paramètres
_stream.videoStreamSettings = h264Settings;
}
if (_mic != null)
{
_mic.addEventListener(ActivityEvent.ACTIVITY, activityHandler);
_stream.attachAudio(_mic);
}
if (_camera != null || _mic != null)
{
metaData.copyright = "My Company, 2015";
metaData.codec = _stream.videoStreamSettings.codec;
metaData.profile = h264Settings.profile;
metaData.level = h264Settings.level;
metaData.fps = _camera.fps;
metaData.bandwith = _camera.bandwidth;
metaData.height = _camera.height;
metaData.width = _camera.width;
metaData.keyFrameInterval = _camera.keyFrameInterval;
_stream.publish(name + '?adbe-live-event=ourownliveevent', 'live'); // bon paramètres
} else {
trace('Please check your camera and microphone');
}
...
...
}
After publishing the stream, we have in the logs/_defaultVHost_/livepkgr/_definst_/application.00.log

Then, we requested the HLS-LIVE stream by : http://<ourserver_address>/hls-live/livepkgr/_definst_/ourownlivevent/teststream.m3u8
Inside de apache error_log, we have the following entries :

...
...
Actually, the stream is unreadable.
If in the publisher we either deactivated or commented the block which attaches the microphone
...
_stream.attachAudio(_mic);
...
We wouldn't have this error with apache, and mobile devices would be able to read and play the stream.
Any help will be welcome !!!
