RE: [Zope] any streaming audio formats that Zope can serve?
Check out Microsoft's Advanced Streaming Format (ASF). It supports anything from audio to video to PowerPoint files. Microsoft includes a real-time encoder with their free streaming tools. Download it from http://www.microsoft.com/windows/windowsmedia/. For information on serving live/on-demand content, check out http://www.microsoft.com/windows/windowsmedia/host.asp. Unfortunately it's not exactly cross-platform, although iirc Microsoft has ported Media Player to Linux. -- Alexander Staubo http://www.mop.no/~alex/ "He could open a tin of sardines with his teeth, strike a Swan Vestas on his chin, rope steers, drive a steam locomotive and hum all the works of Gilbert and Sullivan without becoming confused or breaking down in tears." --Robert Rankin, _The Book of Ultimate Truths_

Martin Dougiamas wrote Are there any "streaming" type audio formats that don't require a special server? Then Zope could just deliver this to ZServer (or Apache) and let it stream the data to the end system.
MP3 streams very well. eg http://www.icecast.org and http://www.shoutcast.com And there are free versions of decoders and encoders. http://freshmeat.net
Played a bit with this - mp3 is expensive to encode, and also isn't all that great for compression for the data I have. The data I have is 12 bit 6kHz sound samples, and it's necessary to convert it to a much higher resolution format to use it with MP3.
Realaudio also streams pretty well over http.
I need to be able to convert data on the fly - unless things have changed, the realaudio sound format converters are expensive, and just not very good.
Current plan is to play with using the Quicktime4Linux library to stream the data. I'll post more when I have had more of a play.
(For those that are interested: the application in question is to allow a user to browse a voice message box, and select voice messages to play. It currently delivers a .wav file (generated by an external method) and the browser downloads it before playing...

Hm. Even if their encoders worked on anything useful (no, I will not, by choice, run an NT server in a different country - way too much of a maintenance headache), it looks like the encoders are all GUI based. Not really useful - I'm dealing with a variety of on-demand content. I can see an easy path is going to be to wrap the earlier mentioned quicktime libraries into a python module... Anthony

This is not quite correct... You only get an old version of NetShow with the codecs coming "real soon now" as of the past year ;) It is not that useful iirc ;) Cheers, Anthony Pfrunder
