Hi all
We are currently using SMIL in a customer project.
While writing the implmentation we use a trial version of oratrix's
GRINS Pro 1.5,
the Real System G2 Authoring Kit and mostly a text editor.
We designed the follwing implementation goals:
1. Have a texstream in the begining to keep buffering time as close to
zero as possible
2. Do not show the Real Log0 while buffering
3. Have an image loaded after the textstream instead of the Real Logo
for advertising purposes.
4. Make a transition into a live stream at the moment the stream has be
successfully loaded into the buffer
and advertising time has passed.
We discoverd the following:
Teh Real Player does not understand relative URLS's,
eg: ../image/loading_movie.jpg
must be : /labor/image/loading_movie.jpg
There is no way (or at least we did not find one) to embedd a live
stream using thze Oratrix's authoring tool.
There is no way (or at least we did not find one) to do a transition
into a live stream.
There is no way (or at least we did not find one) to do a transition
from a textstream.
There is no way (or at least we did not find one) to do design a set of
<seq> and <par>
avoiding buffering the entire clip.
The complete structure is open at http://firn.kunst.ch/labor/
I have attached the code at the end of this posting.
As far as I have understood the SMIl 2.0 W3C Working Draft 01 March 2001
there will be the possibilities to do transitions.
Will the current methods of doing transitions with the RealPix methods
become obsolete or will there be two concurrent methods ?
When can we expect an SMIL 2.0 Implementation in Real Player ?
We would welcome any comments and answers.
