I have been playing a bit with Wowza v2 and v3 to explore it's possibilities of streaming ao Silverlight Smooth Streaming.
With v2 I was able to stream out of the box with the Expression Encoder generated ism file, but the same fileset failed to play on Wowza v3. After some debugging, the problem appearantly lies with the property systemBitrate of the video element. Microsoft Expression encoder writes systemBitrate as propertyname, whilst Wowza v3 is expecting system-bitrate. So it fails to parse the video element and doesn't find any streams.
After checking the SMIL recommendation it appears that the hyphenated form is SMIL 1.0 and has been depecrated in SMIL 3.0 in favor of camelCase conventions.
Is there a way to make v3 behave like v2 and honour the camelCase convention through configuration or software update?
