Audio codec:G711_ALAW isCompatible:false

Hello.

I am trying deliver video with video:H.264,mic:G.711. from flash(as3)

but,wowzastreamingengine_access.log

LiveStreamPacketizerPacketHandler.handlePacket[liveorigin/definst/stream-test]: Audio codec:G711_ALAW isCompatible:false

can’t Wowza use Microphone codec:G.711??

Flash code(as3)

var mic:Microphone = Microphone.getMicrophone();

mic.codec=“pcma”;

or

mic.codec=“pcmu”;

It becomes both error…

please tell me,why…

You should be able to playback a stream with g.711 audio in Flash RTMP. At present, g.711 is not packetized for RTSP clients and it doesn’t work on HLS or HDS clients.

For RTSP, HLS and HDS clients, you will need to transcode the audio using the Wowza Transcoder using the Audio Only template:

Hi,

Generally G.711 playback should be possible from a plash player, but it depends on the implementation of G.711.

Wowza Streaming Engine will pass the G.711 through to the player in RTMP streams, but it’s upto the player how

to handle it.

Hi,

Not RTSP streaming for playback yet, but that is coming soon. Right now it should play over RTMP in a flash player for instance.

Hi,

RTSP playback of G.711 (a-law/u-law) has been added in the latest 4.2.0.1 update.

You’ll find the update in the MyDownloads section of your Wowza Portal account.
