Can you listen to Ogg Vorbis streaming?

One of my friend was going to have me listen to his music by steraming. Those formats were Ogg Vorbis. Although I added some plug-ins for QuickTime, I was unable to listen to them. And to make matters worse, I crashed whenever I turned on Music Control. :(
Other Window's friends had no problem. Is this a known issue or my specific problem?

I'd love to know the answer to this as well.

The main radio streams used on my land are Ogg, which is a major problem if it's causing Mac users (like myself) to crash out.

It's a known issue for countless Mac-using residents I know. Absolutely, verifiably, Ogg Vorbis streams are causing crashes on the Mac clients. I have not seen this listed on the "known issues" list so far, however, for Linden, so one might surmise that it's not been looked into or confirmed by them (yet).

Please make sure you send crash logs, AND file an explicit bug report using the reporting tool so that hopefully our friends at Linden Lab will get this one repaired.

In the meantime, you might visit www.icecast.org and their list of 3rd party players. VLC and MPlayer both have Mac versions, and support streaming playback, as well as Ogg playback; I do not whether they do both together (streaming Ogg), but it may be worth checking. Obviously you'll need the stream URL of the property to listen outside of the SL client...

OGG. A CODEC problem for many...
07-27-2006 11:33
COPING STRATEGIES:
1. Get the latest OGG codec for Quicktime for your machine: WWW.XIPH.COM. BUT, if you have an INTEL MAC, keep reading:

2. The latest QT codec version 0.1.5 will not stream using QT with Mac Intel..

3. Meantime, use a free external player such as VLC. Not only will they play OGG, but VLC will play a number of legacy PC video formats.
--VLC is free and will play streaming OGG. Its an external to SL player. Get it at: http://www.videolan.org/vlc/
--If you want to use MPLAYER, Mac users can go here: http://mplayerosx.sourceforge.net/ (although I don't know of an Intel Mac version). Again you need to start it outside of SL.
--You need to start VLC (or MPLAYER) separately from SL. In VLC, use FILE/OPEN URL
--Do NOT turn on the SL audio. SL will crash while VLC's music will play on...

EVENT ORGANIZERS and LAND OWNERS:
--Why don't you stream MP3? Barring that,
--PLEASE POST URL's for your tunes. A warning sign, "Caution OGG Zone" will keep lots of people from crashing out of SL.. and will save you a lot of IM queries about where to find the incoming stream, and where to find codecs, etc....

My Intel MAC crashes whenever I turn on any OGG stream from within SL or QT.
The problem with OGG is NOT with SL, its that no 'OGG' streaming codec is available for the INTEL macs' Quicktime. (local file playback works, just not the streaming) I believe that SL uses QUICKTIME as its media player...and until QT gets a native OGG codec, SL will crash becuz its QT calls crash. Until the codec happens, there's not much the Lindens can do.

Thanks, guys, for informing me that. I commented on this at Second Life Knowledge Base, "How to Add Streaming Music to Your Land" though the administrator was censoring it. I will send the crash report from in-world when I would get this trouble. I hope SL can prevent at least crashing.

Because you need twice the bandwidth to get the same sound quality. If you want to broadcast in stereo, you really need 128Kbps for MP3, which is EXPENSIVE, and more bandwidth than most of the SL-oriented streaming providers even offer. With OGG, you can broadcast at 64Kbps in stereo and get good quality.

I'd like to see SL support AAC streaming. In that format, you can go down to 32Kbps and get decent sound quality; to the best of my knowledge, it's the most bit-efficient compression format for music so far.

The quality differences are mostly in low-bandwidth streaming; throw enough bits at the problem, and the formats level out. 192Kbps MP3 encoded by LAME is about as good as compressed audio gets in any format.

There's also mp3PRO, but that requires a special codec SL doesn't support being that its closed source and costs more in royalty fees.

I think they already do AAC streaming through Icecast, I could be wrong but I do remember seeing something about streaming AAC audio.

Eh not true, I've seen and used some pretty decent compressed audio formats that do sound better beyond the 192kbps range. Ever hear of MusePack (*.mpc) or FLAC (*.flc)? MusePack is a lossy codec that focused their efforts on better high bit rate compression and auido quality. I've given it a try and its pretty good, but I don't think anything streams it at this time. FLAC is a lossless audio format wich is more of a zip varient designed specifically for audio compression without stripping audio quality out to shrink the file further before compression. FLAC I know for a fact can be streamed as there are instructions on how to do it through Icecast, unfortunately this requires ALOT of bandwith.

Why wouldn't SL support AAC (MPEG 4) streaming, anyway? It's using Quicktime and that's a native Quicktime format.

I wasn't talking about lossless compression formats (FLAC, APE, MLP, WMA Lossless, or AAC Lossless); I'm aware of them, but they don't provide as much compression as the lossy formats. Even at 192Kbps, MP3 is compressing audio about 85%; the lossless formats seem to only be able to manage 20-40% depending on musical content.

I hadn't heard of MusePack. How efficient is it, and is it really any better than high bitrate MP3 (especially when encoded with LAME, which is better than the official Fraunhofer encoders)?
