View Full Version : Another new idiot question...

I'm probably not the first to ask this and did scan through 3 months worth
of archives before plunging in..

I've been following the growth of the consumer wireless audio impatiently
waiting for system to include the features I want which are pretty much all
there now except for the big stumbling block of providing the capability of
Real Audio audio streams over 8002.11B. We can do it for streamed MP3 and
WMA but its still sadly lacking for Real Audio. I suspect its due to
licensing issues but would love to know for sure.

On the MAC side there are Audio Hijack capabilities (Nicecast) software that
can grab the audio produced by a stream and to then stream it out over the
wireless network. Such a facility does not apparently exist for the Windows,
I'm hoping I'm wrong, but wish to confirm that theory.

If I could get Real Audio support working by whatever means in Slim Devices
I would be all over it like a nasty rash! ;)

I can see a development project coming on if there is not already a facility
to do this and would appreciate some guidance / info if you have it.

Thanks,
Phil

No, you're not the first, but that's OK. :)

RealNetworks doesn't, to my knowledge, support any application that
doesn't talk directly to audio hardware. The Helix player, supposedly
Real's Open Source branch, is in my experience nearly impossible to
build, and still doesn't support the full range or Real codecs. And it
doesn't output a decoded audio stream.

The AlienStream plugin has had some Real streaming success. It uses the
Xine libs, which also don't cover all the codecs. You might have
guessed by now that Real keeps a few cards up its sleeves

A more or less standalone program that takes a Real rtsp: stream or .ra
file and outputs wav to stdout would be the ideal item. That would plug
right into the transcoding structure. If you're building for Windows,
don't forget to reopen STDOUT as binary or set binmode().

If you decide to tackle it, be sure to mention it on the developer's
list. That way, we avoid duplication of effort.
