This is WM video reflected from a WMS. I've tried many combos of bit rate, resolution, frame rate, etc. No joy. I'm not talking about 'fuzzy', I'm talking about blocks as big as your fist.
Silverlight seems to work well with stored video, but not live as far as I've seen so far...
Any ideas would be more than welcome!
I also find that multicast does not seem to work (e.g. pointing to a .nsc file).
Haha that is one funky effect in Silverlight.
It looks like it's displaying the keyframes ok but everything in between gets messed up.
I think you should create a new thread with some info about your encoder (it is a vBrick appliance?) and your settings. And some screenshots so they can see what's going on. And you say that if you record a bit of this stream on the server, and then play
that as an on demand file in Silverlight everything is ok?
I do not have this problem myself using Windows Media Encoder and version 9 codecs for both video and audio.
And yeh multicast is not supported. There's more streaming related topics in the
Video and Media forum btw.
>>>>* so far in my own tests I have not been able to get Silverlight to use either Fast Start or Advanced Fast Start. For me it behaves like the old mediaplayer where I get 6-8 seconds of buffering no matter how I configure my server or encode my streams.<<<
This appears to still be the case. Buffering is painfully slow, both on start and when using slider. With the standard MediaPlayer plugin buffering is almost instant, same with using the slider.
Until this issue is resolved we simply cannot justify using Silverlight to deliver viideo.
this is our EXACT same issue as to why we can't roll Silverlight out. We are on Windows 2003 Streaming Server and we use WMP (Windows Media Player) for Windows and QuickTime for Mac. Replacing QuickTime with Silverlight seems to help us on that part, but
for Windows, we lose the quickness of the stream if we move to Silverlight.
We want to move to Silverlight as a complete platform, but the fact that it starts streaming 5-10 seconds slower than WMP (which streams almost instantly) is a stopper for us. Especially when you load a 1 hour game film and you want to seek by jumping 40
minutes ahead. WMP does it instantly, but Silverlight 2 take 5-15 seconds before it starts the stream.
Your Silverlight sample starts near instantly on my system.
Remember that in Silverlight, your media stream is always coming in over HTTP on port 80, it's not impossible that you're running a firewall or virusscanning that slows loading these media files.
And when you skip ahead you still see it near instanty playing the stream? We have tested in 5 states on various machines and we see the small 5-10 second delay when users skip around on video. We don't see it anywhere on WMP.
We go over port 80 HTTP in WMP as well so there is no difference for us on port/protocol between the two players. We have set WMS to use only HTTP (so no MMS, etc.).
Note that you'll need to use a non-IE browser to get the Silverlight version, IE users default to WMP.
The stream comes from Windows Media Server on Windows 2003, it has fast start enabled, not advanced fast start as that is something else entirely. This sample runs in SL 1 and 2 and Moonlight 1 (as long as you grab a more recent build than December's beta).
On my test systems, loading and jumping through the stream gives good results.

You can view the live video at: www.textthefish.com
If you want to try to make Silverlight behave with live video, usemms://powerhost.live.powerstream.net/00300000_live2

Indeed, jumping around in your stream does have some longer buffering times.
Try this URL if you can (this sample is hosted from the Netherlands, so results may vary depending on where you are)
