When i set transcoder for audio : PathThru video is Ok but of course no sound…

Paramets of DVB audio:

MPEG audio layer 1/2/3 (mpga)

Channels 2

Rate 48 000 Hz

BitRate 192 kb/s

Any Ideas ?? thanks

Is it a developer license? The beep is an audio watermark. A Subscription or Perpetual license with Transcoder addon will not have this.

Richard

Are you playing one of the transcoded renditions, like “VTV.stream_360p”

Wowza should not introduce any sounds other than watermark.

Richard

Do you have a link to the stream to play? If so, you can send it to support@wowza.com

Also, restart Wowza, start the stream, test playback in the Wowza FlashRTMPPlayer, then zip up and include /conf, /logs and /transcoder folders

Include a link to this thread for reference

Yes i play VTV.stream_360p May i save input stream (ts) and send you/ May be its help you to understand? May be problems in stream and not in WOWZA ? Some other streams working correctly.
