Silverlight Streaming v2 Test - check this out

I'm doing some work with the Expression Suite v2 Beta and part of that is control over the player properties for the streaming video.  This is pretty important for posting to my blog.  But I do believe I have this figured out now.  Here's a HD 720p stream.  In order to play this video, you probably need a rather fat pipe.  If it doesn't play smoothly, please comment on your ISP connection.

For the embedded player control below, there are a few things I'd like you to test.

  1. Full screen button - on the player bar, the icon on the far left makes the video play full screen. ESC gets you back out of full screen mode.
  2. Pause - check to see that it pauses and resumes.
  3. FF/Rewind - with this embedded control, it doesn't really fast forward or rewind.  It should however move the current video position on clicks to either button.  I noticed you can't really move around in the video until the download is complete.

What do you think?  Pretty rad, eh?

[UPDATE] I have changed the encoding so that the bit rate is now 3MB instead of 6MB.  I am also testing the download and autoplay UI in Encoder v2 Beta.

[UPDATE for 6/15/2008]  It's back to 6MB.

  • That was impressive, the streaming went flawlessly, but I have a 100MBit connection, but suprisingly I had some playback issues (dropped frames, stuttering). I have no problem with playing local 720p files.

  • Hans, where are you located?  If you are overseas, some of stuttering and dropped frames were likely due to latency.  If you are where I think you are, you were playing the video like 4800 miles from the origin.

  • i have a 10mbit pipe through comcast and it played perfectly, even at full screen. control worked ok, too.

  • Played great at full screen, took 25 years to download with Ma Bell and her 3 mb coconut radio dsl, sounded good, too. Not bad.

  • 10mb Charter pipe, played flawlessly.  Very cool.

  • RosCo,

    Did the video start playing near instantly after clicking the big start button?  Normally SilverLight Streaming will start playing pretty quickly as long as the play buffer can stay ahead of the download buffer.

    In this case, it's a 6Mb stream so I would imagine a 3Mb connection would have a hard time staying ahead so it might have to download half of the video first.

  • Played flawlessly here. I only have a 7mbit pipe from RoadRunner.

  • I am on a 10Mb cable modem in Vancouver, BC.  The video started playing about 3-4 seconds after I hit play, so nice quick start up.  Audio quality was good, and the resolution of the video was awesome. The was some video studder throughout the clip though, it wasn't too major (mabye a 1/4 second max), but it happened probably 8-10 times during the entire video.  Pretty nift to watch someting full screen and have it look that crisp from an online stream.  Very impressive.

  • dropped frames & stuttering

    15Mb from Time Warner

    pretty cool!!

  • Took a while to get started, Keith. You are probably right in that it downloaded half of the file before we could get going. How big of a file is it, by the by?

  • Dedicated 6 Mb (Ethernet via fibre) connection, but I couldn't get it to play smoothly.  Also, in full-screen mode, there didn't appear to be any player controls.  Beautiful quality, though!

    As an aside, I remember when my dad used to bring home materials on the F-16 and the F-20--my understanding at the time was that they were deciding between those two planes to replace their F-4s.  Sometimes it's amazing watching how maneuverable the F-16 is.

  • Video looks great, but had to keep re-buffering the video about every 15 sec.  I've got a 5Mb cable connection with Charter.

  • Andrew,

    I am just testing the upper bounds so for those of you with connections at or below 5MB, thanks for the feedback.

    The real work I'll be creating will be in the 1-3MB range so a 5MB connection should be good for the stuff I have coming.

  • Very nice clear picture...

    I have a 20Mbps Comcast cable connection in Oregon, and it was stuttery. Oh so stuttery.

    I saw about a fourth of the actual frames :(

  • Most of it is pretty smooth and watchable, now that I look at it, but there are still parts in the video that are very stuttery.
