Without that (i.e. using software-emulated floating point), this cpu is far too slow. No fixed-point vorbis _encoder_ exists, currently. So there's no chance at all with vorbis, unless you want to write such an encoder (this is a Very Large Task). For mp3, it might be possible. I think fixed-point mp3 encoders exist, though they're not (afaik) competitive on quality with things like LAME, and there may not be any free (non-commercial) ones (you'd have to pay the mp3 licensing fees anyway). You'd have to investigate.

Has anybody used anything other than a PC as a source for icecast2? Are PDAs powerfull enough? I know vorbis encoding takes a signifigant amount of CPU power, but I've been able to do it on 4 year old PCs. Does a 206MHz Intel StrongARM 32-bit RISC processor have as much power as a 200 Mhz Pentium? I'm thinking Compaq iPaq, running Familiar Linux and IceS, would make a nice portable $220 source.

Via which way do you intend to have e.g. a line-in to the iPaq with reasonable quality. Would be really interesting to figure out such things ... and then use a WLAN-cradle to transport data to the internet *g* Stefan --- >8 ---- List archives: http://www.xiph.org/archives/ icecast project homepage: http://www.icecast.org/ To unsubscribe from this list, send a message to 'icecast-request@xiph.org' containing only the word 'unsubscribe' in the body.

Since these would already have a PA mixer at them, generally I'd just use an Aux out (line level) from the mixer to line in on the PDA. But a single XLR mic with a converter to 1/8" phono should work too, right? What's the audio quality built in to a PDA like, anybody? I've never used one. I do know that PCMCIA cards for Professional audio exist, which could be an option if the built-in isn't good enough. <p><p>>> Stefan > --- >8 ---- > List archives: http://www.xiph.org/archives/ > icecast project homepage: http://www.icecast.org/ > To unsubscribe from this list, send a message to > 'icecast-request@xiph.org' > containing only the word 'unsubscribe' in the body.

Akos, the darkice developer, said a while ago that Darkice should be able to be compiled and run on the Sharp Zaurus. I have just tried this but no luck, it just returns 'cannot execute binary'... i have ogglibs and vorbis libs installed on the zaurus so if anyone knows anyway to stream using ogg on a strongarm pda, i would be most grateful to know more i will also try cross compiling for the zaurus Qtopia environment but i first need to know more about how to make '.pro' files...if there is anyone that can point me at a resource for this too, that would be great :) in the meantime i have had zaurus using 'zmeeting' which does instant messanger type 'realtime' voice messenging and the quality seems quite ok, and it interacts with gnomemeeting really well...looking forward to the possibility of streaming ogg though.... adam <p><p><p><p><p><p><p>On Thu, 24 Jul 2003, Joern Nettingsmeier wrote:> Luke Stodola wrote: > > Has anybody used anything other than a PC as a source for icecast2?
