Silverlight on the iPhone Hints?

by on Mar.06, 2008, under RIA, Silverlight

As Mix ’08 is currently going on.  Scott Guthrie said something that peaked my interest.

He basically said that

"Our goal is to try to get it on as many mobile devices and allow you to just take advantage of it umm with a variety of different clients… Everything that has an SDK"

He was very hesitant when he said it.  Did he allude to Silverlight iPhone??  The timing is impecable.  He said this on Wednesday March 5th 2008, where the Apple event is today March 6th 2008.

You can view what he said by accessing http://wm.istreamplanet.com/customers/ms/750_microsoft_mix_080305.asx in Windows Media Player or VLC or other compatible player.  He said it at 2:26:00

I wonder if Adobe has something between Desktop Flash and Flash Lite?  I would still like to see flash on the iPhone, Maybe the iPhone SDK will allow that?

Only time will tell…

KulaByte

by on Jan.21, 2008, under Streaming, Video

In researching Flash Media encoders, I came across a company called KulaByte.

I was impressed with their solution — A live two pass Variable Bit Rate (2 pass VBR) encoder!!  They have definitely accomplished an incredible feat.  The two pass encoder basically splits the video into segments and utilizes multi-core systems to execute a 2 pass encoding before bringing them all back together.  I can imagine the complexity of doing this with a GOP based codec.  All in all, they told me that it introduced around 15-25 seconds of lag time on the encoder.   Realistically that is Acceptable in the Broadcast market.

They gave me a demo of their Xstream solution (not to market yet).  The Video quality was excellent.  It was what I expected from a 2 pass VP6 encode.  It was hard to see the artifacts at 900kbps, although I did occasionally see some non-traditional artifacts.  I am a videophile and am super picky about video quality.  I’ve seen artifacts like these using Windows Media Encoder’s live preview.  To best describe them, its like a set of pixels (box, group, etc) can’t decide whether to be up 1 pixel or down 1 pixel so it just flops back and forth a few times.  I’m not too concerned with the artifacts, but I’d like to learn what to call them.  Maybe it was just the source video, I don’t know.

The Video Quality was second to none in terms of a Live broadcast.  I was thouroughly impressed.  Because of the multi-pass situation, their software requires some awesome Multi-core hardware.  They even have a portable package that includes a 4 core laptop!!!

All in all, I am very impressed by their work!!  I might utilize their systems in the future.  Keep up the good work KulaByte!!
