Does anyone know if there is an open source program that does the same as RealPlayer? Especially if it can read RealPlayer datastreams? The reason I ask is that one annoying thing about RealPlayer is that it will only play a datastream as it is being connected to the stream via the Internet; it will not allow the stream to be saved and played back later. This can be problematic when one has a slow or intermittent connection (i.e. most times). Also, saving it would allow it to be replayed again later, without having to connect to the net each time. No doubt RealPlayer see it as a feature of their system that you can't save files; but to users it is a bug. (One could possibly patch the Linux kernel so it would intercept the stream of IP packets from the source to the RealPlayer application to "fool" it into believing it was a real Internet connection -- or do RealPlayer get round that by having a 2-way conversation and encrypting it differently each time?) I suspect also there might be legal issues relating to an open source version, at least in some jurisdictions; i.e. corporate bullying a la DVD-CCA. -- ***** Phil Hunt ***** send email to phil@comuno.com ***** Moore's Law: hardware speed doubles every 18 months Gates' Law: software speed halves every 18 months

RealPlayer doesn't go via http [well, not port 80, anyway]. It requires a special product [RealServer] to stream the media. But I should think eavesdropping on a conversation between RealPlayer and a RealServer should be trivially easy [libpcap maybe?]. I assume there is some kind of low-strength encryption going on [think US exports], but maybe with the recent change in the US crypto laws, release 7 will maybe use stronger encryption? Once you get round the encryption, it is probably no more than good ole' MPEG, my reasoning being that they wouldn't arse about with R&D costs for a new format. However, I could be spectacularly wrong. I was just trying to spec out RealJukebox, but real.com is a bit slooooooow at the moment. It is probably only a matter of time before the real format gets reverse engineered, but expect there is all kinds of patent-related shit going on. alexd Sent via Deja.com http://www.deja.com/ Before you buy.

UPDATE: RealServer basic is a free download, and version 6 will run on just about any OS you can think of. Get hacking. alex d Sent via Deja.com http://www.deja.com/ Before you buy.

Usually you can get at them by reading the HTML. IIRC, the HTML usually contains a reference to a .rpm file (nothing to do with Linux RPM) which is text-based, containing the name of the .rm file, which is the thing you want to save. Realplayer can play them from disc, it doesn't have to come from a server. -- http://www.caspian.uklinux.net Use the address in the Reply-To header to avoid a spam trap when emailing me.
