Silverlight smoothstreaming of mp3

[Arkain]

Hey,

I have finally been able to set up Wowza to steam video (mp4) to flash, iphone and silverlight. The next natural step was to try with an mp3 file. The same setup can stream my test mp3 file to Flash and iPhone, but when I try via silverlight it doesn't work, and the manifest doesn't return anything useful.

Below is the smoothstream URL I'm using.

http://wowza.server01.geckon.com:193...1.mp3/Manifest

Any advice would be appreciated.

Thanks

Jesper,

hm, not sure. The Application.xml looks right, and the mp3 file plays in Flash. But the Manifest is empty.

Check the logs for any Warnings or Errors.

Also, try other mp3 files.

We do not support MP3 file streaming to Silverlight. We will add it at some point but for now it is not supported.

Thanks for the quick replies.

Okay I just assumed wowza would stream MP3 due to the wording of the Quick start guide

Video

* H.264

Audio

* AAC - AAC, AAC Low Complexity (AAC LC), High Efficiency AAC v1 and v2 (HE-AAC)
* MP3

Is there any audio format I can use then, that will stream to silverlight using wowza?

Thanks

[charlie]

Yes, AAC files in an MP4 container.

Hey,

I can see a patch has been released:

WowzaMediaServer2.0.0-patch16.zip
Added support for streaming H.264/MP3 streams to the iPhone/iPod touch/iPad (live and video on demand)
Added support for streaming H.264/MP3 streams to Silverlight
Added support for streaming H.264/MP3 streams to MPEG-TS
Fixed NullPtr exception with RTSP/RTP streaming when rejecting a session
Version: 2.0.0.16 build24317 (16 May 2010 12:10:00 PST)

Does that mean it should be possible to stream mp3 now? and does it have to be in a mp4 container?

/Jesper

[rrlanham]

Yes, as stated, mp3 is supported for h.264 format, and in mp3 container.

Richard

[Arkain]

Thank you for your answer.

Then I have a problem somewhere, the following points to a mp3 file, but the manifest shows nothing:
http://wowza.server01.geckon.com:193...1.mp3/Manifest

When I do the same for one of the video files in the same folder, the manifest works fine.
http://wowza.server01.geckon.com:193...s.m4v/Manifest

The Application.xml is still the same as posted before.

This is the version:

Wowza Media Server 2 Developer 2.0.0.16 build24317

[rrlanham]

I tried an mp3 file I have, and got the same results. It plays in Flash, but no Manifest.

I inspected with Gspot, and it says the audio codec is " MPEG-1 Layer 3".

The devbuild page for patch 16 says:

Added support for streaming H.264/MP3 streams to Silverlight

But MPEG-1 is not h.264.

Check your MP3 file codec with Gspot:

Sorry, my mistake. MP3 is supported, but not in mp3 container. Has to be mp4 container for Silverlight.
