Live stream published with either FME or WireCast… H264 and AAC… tried a bunch of things but the Silverlight stream always gets this error:

Streaming Error: Failed to download manifest: d

The stream works fine in Flash and straight RTSP.

Any help appreciated,

Matt

The tutorial for that type of live streaming is here:

[https://www.wowza.com/docs/how-to-set-up-live-streaming-using-an-rtmp-based-encoder](https://www.wowza.com/docs/how-to-set-up-live-streaming-using-an-rtmp-based-encoder))

If this does not help, then enter the Manifest URL directly in a browser. It will return XML data. Post that data here.

One critical issue is that there is no audio track in the manifest, only video. It’s difficult to get Silverlight player to work without an audio track.

It works in my test using Wowza 3.5.2.01 and the VideoOnDemandSteaming Silverlight example.

HI Charlie, thanks for your response.

The stream I have created was based on that tutorial already so this is what I get in the browser:

Actually, the previous XML was using FME… This is using Wirecast:

Hi,

I have the same problem with SmoothStreaming. In the Wowza Live Smooth Streaming test html page, I get the error: “Streaming Error: Failed to download manifest: d”

BUT rtmp, hls, and rtsp stream works great.

The settings are same as in [https://www.wowza.com/docs/how-to-set-up-live-streaming-using-an-rtmp-based-encoder](https://www.wowza.com/docs/how-to-set-up-live-streaming-using-an-rtmp-based-encoder). The stream has AAC audio, and the keyframe intervall is 2 seconds.

Here is the Manifest:

What’s wrong?

Thanks!

Tamas!

Hi,

I have the same problem when I play “sample.mp4”. In the Wowza VideoOnDemandStreaming SilverlightPlayer test html page, I get the error: “Streaming Error: Failed to download manifest: d”

BUT rtmp, hls, and rtsp stream works great.
