Subject: Re: Q: Multiple instances of RealProducer?
Instead of running the following:
RealProducer Instance #1: audio only
REalProducer Instance #2: Audio + video
* problem here is each instance tries to grab the sound card and they can't.
Use the following configuration:
RealProducer Instance #1: audio only (call this audio_only.rm)
REalProducer Instance #2: video only (call this video_only.rm)
Then link to the above streams as follows:
audio only:
<smil>
... some layout if desired ...
<body>
<par>
<audio src="audio_only.rm"/>
</par>
</body>
</smil>
For the video and audio use the following smil file:
<smil>
... some layout if desired ...
<body>
<par>
<audio src="audio_only.rm?wallclock=foo"/>
<ref src="video_only.rm?wallclock=foo"/>
</par>
</body>
</smil>
The wallclock argument forces the streams to sync together based on the
timestamps of the machine they were encoded on. In your case they are encoded
on the same machine. IN the case where they are encoded on different machines
make sure both have synchronized clocks.
Cheers!
