oops the last was in HTML and I know alot of you won't answer html email How come the song data shows up faster with ogg when with mp3. I ask this because the people who are using icecast to stream police scanners also made a system to send realtime updates to what channel people are listening to. With Ogg the title shows up about .5 of a second before the talking starts but with mp3 it's about 1-2 seconds after the talking starts. Is there anyway to speed up the text on mp3 or are we just stuck with it? -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Weather @ 5:15pm * Temp: 20.9 ?C * Humidity 55 % * Wind: SSE @ 0 km/h Baro: 1021.04 kPa Falling * Vis: 24 km * Sky: Broken Clouds * Weather: None reported 24H Rain: 0.00 mm * TotalRain(Sept 1st 2004): 27.00 mm =-=-=-= Website: http://www.WeatherServer.net =-=-=-=-=-=-=- Southern Ontario Weather Email Alerts, Atlantic Hurricane Email Alerts

I believe by default icecast will send metadata updates every 8 or 16k, regardless of the bit rate. It sounds like you're probably using a very low bit rate, which means 8k could be a couple of seconds. I don't have the icecast source here, but if it's not already a config option, it shouldn't be too hard to lower the value in the source. Since metadata only costs a single byte every interval when there's been no change, it shouldn't have any noticeable impact on your stream, even if you lower it to 1 or 2k.
My problem is I run the win32 version and i'm guessing there isn't just a entry i can add to the icecast config file. ----- Original Message ----- From: "Brendan Cully" <brendan@xiph.org> To: <> Sent: Tuesday, September 21, 2004 5:31 PM Subject: Re: [Icecast] mp3 vs ogg question (reformatted)> On Tuesday, 21 September 2004 at 17:16, Jason wrote: >> oops the last was in HTML and I know alot of you won't answer html email >> >> How come the song data shows up faster with ogg when with mp3. >> >> I ask this because the people who are using icecast to stream police >> scanners also made a system to send realtime updates to what channel >> people >> are listening to.
