Apple iPhone iPod Touch App and MP3 Stream

Joined: 15 Oct 2009 Posts: 3

Hello,

first, it would be great to have an iPhone App for Kohina. That would make it alot easier to listen to Kohina on the iPhone. There are already similar Webradio-Apps avaiable, so if somebody has some coding skills it should be possible.

Right now I use the App "FStream" to listen to Kohina since FStream supports OGG. The Problem here is, that OGG is not a native iPhone Codec so FStream uses on-the-fly decoding for OGG. That uses more CPU Power - and thats the reason why the battery drains so fast.

I know, that MP3 is not ur favorite Codec, and I also prefer the Opensource Codec. But for compatibility reasons it would be nice to have at least one MP3 Stream.

That would also be a plus for listening to Kohina on Systems that do not support OGG natively, like Mac OS or Windows, when you dont have any possibilty to install the codec (like in companys etc.).

Keep up the good work, and keep Kohina alive! Smile

+1, I have the same problem on Android (HTC Hero), except here I don't know of any app playing OGG at all, making it impossible to tune in. I usually play chiptunes for my baby daughter, but then I have to use VLC to record a listening session, convert it to MP3 and transfer it to the mobile.. which doesn't exactly give the same experience.

So if not for us, do it for the children! Smile

Both ogg and mp3 are compressed formats...comparatively, they both take an amount of CPU power to decode. If you mean that the iphone has a hardware mp3 decoder, then that's different, otherwise both streams would have to be decoded.

Most companies disallow streaming media to begin with...if you're actually allowed to listen to webradio, it's likely that you'd be able to bring a noninstall player on a thumb drive, i.e. winamp, which is what I do. In addition, most companies throttle traffic which makes it hard to listen to anything past 64k.

Android should support ogg, so they say, but that has to be single ogg-files then. At least, I'm unable to open the .m3u file from Kohina. Anyone?

I'm going to look into creating a low quality mp3 relay here in the states...for guys like me who do have throttled work connections and only Windows media player available. Stay tuned.

Edit: With Kohina's permission, of course.

If anything, it'd probably be a 48kbps mp3 stream...and my home conn doesn't have much capacity for more than about 10 listeners.

the iphone supports hardware assisted decoding for mp3 but not for ogg.

you can find more information about that in the iphone dev center:

thanks for your help Smile
