VOD to Microsoft Mediaroom through smoothstreaming

Question

I'm following the VOD tutorial to stream the sample.mp4 to a Microsoft Mediaroom. It works on the example silverlight player, but not on the STB. The box requests the manifest, the httpSmoothStreamingSession is created, but after a few seconds the stream is destroyed.

Has anyone attempted this before?

I've haven't tried MS Mediaroom. I have tried Smooth streaming to WMP, and that did not work.

This is what I'm getting in my logger. Does it ring a bell?

I'm working on this again. I've tried feeding video to the STB using IIS and it works. After comparing the manifests generated by IIS and Wowza, and looking at the logger, I've concluded that the problem must be the way the STB is building the Url specified in the StreamIndex tag. In Wowza's manifest it has the following structure:

<StreamIndex Type="video" Chunks="204" QualityLevels="1" MaxWidth="424" MaxHeight="240" DisplayWidth="424" DisplayHeight="240" Timescale="10000000" Url="QualityLevels({bitrate})/Fragments(video={start time})/Chunks({chunk id})/WowzaSessions(382630294).ismv">

While on IIS it is generated this way:

<StreamIndex Type="video" Name="video" Chunks="136" QualityLevels="8" MaxWidth="720" MaxHeight="480" DisplayWidth="720" DisplayHeight="480" Url="QualityLevels({bitrate})/Fragments(video={start time})">

Using Wowza, the STB tries to access the url:

 vod/300_p.mp4/QualityLevels(121340)/Fragments(audio=0)/Chunks({chunk

Is there any way I can change the URL structure generated in Wowza's manifest? Do you think implementing some sort of proxy between Wowza and the STB to fix the URLs would work?

Thanks in advance.

Try this patch. It includes smooth streaming changes for Windows 8. Probably same issue on MediaRoom:

WowzaMediaServer3.1.1-patch9.zip

Any news on this? As you know, Microsoft Mediaroom is the world's biggest IPTV platform... I'm sure you have a valid business case to support this...

Also, is there any way you can support live MPEG-TS streams over HTTP? Mediaroom only supports live OTT MPEG-TS streams encapsulated in HTTP, not in RTP/RTSP... (Even if get you Smoothstreaming working on Mediaroom, officially Microsoft only supports SmoothStreaming for VOD content, not Live)

Hi..

Any news about this problem?

This Manifest works in mediaroom:

http://playready.directtaps.net/smoothstreaming/TTLSS720VC1/To_The_Limit_720.ism/Manifest

The Manifest generated by Wowza doesn't work.

Any solution.

Both files are in smooth streaming

Thanks

Hi,

we've got the same issue...

we see that's it seams there is a trouble with the generation of the Manifest. some videos works some not...

it's really strange.

Microsoft said to us that the trouble seams to be the chunks ...

if you have any suggestions to change it it would be great

Answer by Richard Lanham · Jan 02, 2013 at 02:09 PM

For .ism files generated by Expression 4 Encoder use "smil:" prefix. But we don't recommend this encoding method (ism and ismv files); it will work but the .ismv files are fragmented .mp4 file which cause CPU spikes when they are started. Also, Expression 4 Encoder can record multiple video and audio tracks to a .ismv file which Wowza does not support, so do not encode that way.

For smooth streams, make sure there is an audio track, and preferably AAC audio

Also b-frames in this scenario have been problematic.

Another user asked: "Do you think implementing some sort of proxy between Wowza and the STB to fix the URLs would work?"

You could rewrite ASCII in packets no problem with Perl, or some other packet mangler. But that doesn't seem like an ideal solution.

In this post user thenriques shows the URL that is requested. If someone could post the Wowza generated URL and a working IIS generated URL from your tests with this MediaRoom issue, that could help move closer towards a solution/patch.
