Speex Audio playing in Flash but not in VLC

Postby Keriadec » 11 Oct 2013 14:37

Hi

I've made a broadcaster in Flash that stream a video and uses Speex for Audio with the following settings :

sound.EnMic = Microphone.getEnhancedMicrophone(Global.micselected) as Microphone;
sound.options = new MicrophoneEnhancedOptions();
sound.EnMic.setUseEchoSuppression(true);
sound.options.mode = MicrophoneEnhancedMode.FULL_DUPLEX;
sound.options.echoPath = 128;
sound.options.nonLinearProcessing = true;
sound.EnMic.enhancedOptions = sound.options;
sound.EnMic.setSilenceLevel(0);
sound.EnMic.encodeQuality = 8;
sound.EnMic.noiseSuppressionLevel = -50;
sound.EnMic.codec = SoundCodec.SPEEX;
sound.EnMic.rate = 8;
sound.EnMic.framesPerPacket = 1;

Video is working fine. Audio is playing fine in our flash app but there is no sound in VLC. We're streaming using Wowza. In the Audio meta of the stream VLC indicate SPEEX in codec but no sound comes out.

You guys think it has to do with the settings in flash, like the 11.3 Enhanced Microphone or maybe it's more a Wowza pb ?
