- Thread-topic: control of streaming media
Greeting Bill,
Windows Media Services is capable of streaming using the RTSP protocol
in addition to the MMS protocol. It is possible to build an Applet or
JAVA WebStart app that uses JMF
(http://java.sun.com/products/java-media/jmf/2.1.1/apidocs/) that could
give the level of control you are looking for. The only potential issue
I could see is the number of codices that would work with JMF. JMF is
all based on open standards so files like WMV would not work. The media
files would need to be encoded as H.261 or another open standard and
streamed RTSP. If all the media in question is WMV then that my not be
desirable approach and the plug-in may be more favorable.
Also JMF fully supports Darwin Streaming Server
(http://developer.apple.com/darwin/projects/streaming/) which is an Open
Source project Apple started. They do have a version that runs on
Windows, OS X and Linux.

A project just landed in my lap to do the following, and I'm hoping it
can
be done in WO. Because it can't be "Windows only" the client has to
steer
away from active-x.
The scenario is this...
Client browser logs in and requests a certain video from a Windows Media
Server. The customer (the one selling access to the video) wants to:
- Offer typical playback functions like Windows Media Player or Apple's
Quicktime allows for.
- Capture all the viewing time, and control cutting off the stream if
they
hit their pre-paid threshold.
- Judge total time 'viewed', including regulating and/or measuring their
use
of 'rewind' and jumping over segments as well. (frames rendered I
suppose)
- Control the buffer so a crafty client doesn't pause playback, buffer
an
entire video, disconnect from the network and then un-pause playback.
My natural inclination is to let this one go by and tell the customer to
find a Windows developer to use the API toolkit from MS for Windows
Media
Player and Windows Media Server. But again, they need 'cross platform',
and
they'd like it without a bunch of plug-ins etc. (applet?)
I'm very interested in hearing if anyone has suggestions.
Eagerly,
-Bill Reynolds
