Hi,

We started a Live application with default configuration for RTMP and MPEG-DASH.

The incoming stream is RTSP from IP camera.

There is no problem with the RTMP Stream reader.

We can’t access to MPEG-DASH. CORS is activated but the reader can’t acces to manifest.mpd.

We have tested with a VOD test on the same server and it’s works fine to read MPEG-DASH(\*\*\*\*vod/mp4:sample.mp4/manifest.mpd).

Do you know what could be the issue with live application to access MPEG DASH ? The reader complains about Access-Control-Allow-Origin not here ?

Thank you

Hello,

It does sound like a CORS error. Did you already run through the options in the [CORS article](https://www.wowza.com/docs/how-to-enable-cross-origin-resource-sharing-cors-for-http-based-streams%28CORS%29-for-HTTP-based-streams)?

Can you view the DASH stream locally on the server using the DASH Test Player?

Best regards,

Andrew

Any difference between players? (Bitdash, Shaka, JWPlayer or DashJS)

Does this occur with a different source such as Wirecast?

Are you on the latest build 4.6.0?

Thank you Andrew for your answer.

I have already tried to configure CORS from this article but it stil doesn’t work.

If try DASH Stream locally on the server I get the following error

==\> …/…/logs/wowzastreamingengine\_error.log \<==

WARN server comment 2016-12-21 15:03:38 - - - - - 153.951 - - - - - – - HTTPStreamerAdapterMPEGDashStreamer.service: Request timeout: 12000

It works fine for vod but not for live ?

Any idea ?
