Hello everyone,

I am using the wowza streaming engine on web with **RTMP** stream protocol. I am using flash and OBS to publish stream and it is working fine with video and audio on web. Now I am facing the sound issue with **RTSP** stream protocol on mobile devices. Video is working fine but unable to listen audio. My video format is h264 with AAC audio encoding. I have also used transcoder but unable to listen audio.

Kindly help me. Thank you

Regards

Saad Ali

Hello,

Does this RTSP output audio work in the wowza test players? What version of Wowza Streaming Engine are you using? What mobile devices are you using?

Can we see a mediainfo screenshot of the RTSP specs?

Best,

JasonT
