All,
Like a number of you, I’ve been hacking away at the Jingle Demo.java trying to get it to work, and I have made some progress. Now, my Demo app will successfully negotiate a Jingle session with a standalone Spark client, but then it fails when trying to access the microphone (this results in a “Voice chat ended: No Media Received” message in the Spark client). I get two stack traces:
WARNING: java.net.MalformedURLException: unknown protocol: dsound

I’m pretty sure this is just a warning, as the smack code will default back to “javasound://”, but it looks like the dsound library is part of JMF so maybe it’s a symptom of something else?
However, I think the worse error is:
INFO: E: javax.media.NoProcessorException: No microphone device available or JMF not installed.
javax.media.NoProcessorException: No microphone device available or JMF not installed.

I definitely have JMF installed, and I’m able to record audio from the microphone using JMFStudio, so I really don’t have any idea what’s going on here. Any help you can provide would be greatly appreciated.
Thanks in advance,
matt
I’ve attached my modified version of Demo.java.
