A different approach: http://www.streamingserver.org. They can point you to Apple's free version of Quick Time Streaming Server (properly called Darwin Streaming Server). Available for RedHat Linux. It will allow you to stream any valid QT format, including MP3. Possibly .avi, but I've never tested that. Quite frankly, AVI really isn't up to the task of streaming. === Subject: RE: Streaming media From: "Chapman, Matt" <chapmam2@ocps.k12.fl.us> Date: Thu, 21 Sep 2000 08:15:27 -0400 works great and streams mpeg and mov very easily... === Subject: Re: Streaming media From: wilson@claborn.net (Jonathan Wilson) Date: Thu, 21 Sep 2000 11:57:24 -0500 Yes I saw that and I am interested in it - personally, I love QuickTime above all the other formats. However, as previously stated, the problem is that our clients specifically asked that we stream in Real Media (very easy, no problem at all) and in something that Windows Media Player can play. Therein lies the trouble - Windows Media player can play .asf .avi and MPEG, but I haven't found a server for Linux that does any of those yet. See, they know that many Windows users will never bother to download a QT player or even Real Player in some cases, and they want people to be able to watch their video right away with no trouble. Personally that makes me unhappy, I think people should always be downloading the newest browsers, and getting plugins and stuff. If it was up to me we'd use QuickTIme and DivX;-) and provide a link to a player :-) But then I use Linux too so I must be *different* ;-) Thanks though, JW P.S. mp3 is not the same as MPEG - I've noticed many people are confused about that. MPEG is video, mp3 is audio only. === Subject: Re: Streaming media From: Matt Housh <jaeger@morpheus.net> Date: Thu, 21 Sep 2000 12:57:11 -0500 > P.S. mp3 is not the same as MPEG - I've noticed many people > are confused about that. MPEG is video, mp3 is audio only. Unless I've gone nuts or this has change, MP3 does indeed mean MPEG, in a way. MP3 is short for MPEG3, which is an audio format. MPEG1 and MPEG2 are video/audio formats. MPEG4 is also a video/audio format? Is this wrong? Someone feel free to correct me if it is... === Subject: Re: Streaming media From: wilson@claborn.net (Jonathan Wilson) Date: Thu, 21 Sep 2000 13:12:28 -0500 Actually, I think you are right - but an mp3 server, for example icecast, cannot stream MPEG1 video - right? I looked over icecast's web site and didn't find anything like that. === Subject: Re: Streaming media From: wilson@claborn.net (Jonathan Wilson) Date: Thu, 21 Sep 2000 13:15:55 -0500 I sure wish I could find an AVI streamer for Linux - I was reading somewhere the other day that "writing an AVI parser" is so simple that many schools use it in classes or somthing like that. If it's so simple to parse it's got to be simple to stream, so how come there isn't an AVI server for Linux? IT would also save my company several thousand dollars :-) === Subject: RE: Streaming media From: Kevin Rooney <Kevin_Rooney@sw.cc.va.us> Date: Thu, 21 Sep 2000 14:24:57 -0400 Actually, mp3 stands for MPEG-1 Layer 3 audio. MPEG-1, MPEG-2, MPEG-3, MPEG-4, MPEG-7,and MPEG-21 are all video formats.

MP3 = MPEG1 Layer 3 and describes the psycho-acoustic compression of audio signals only So MP3 is actually part of MPEG 1, but Layer 3 is the audio.... MPEG3 doesn't actually exist anymore... >From [71] Introduction to MPEG (long) FAQ http://www.faqs.org/faqs/compression-faq/part2/section-2.html Q: What is MPEG, exactly? A: MPEG is the "Moving Picture Experts Group", working under the joint direction of the International Standards Organization (ISO) and the International Electro-Technical Commission (IEC). This group works on standards for the coding of moving pictures and associated audio. Q: What is the status of MPEG's work, then? What's about MPEG-1, -2, and so on? A: MPEG approaches the growing need for multimedia standards step-by- step. Today, three "phases" are defined: MPEG-1: "Coding of Moving Pictures and Associated Audio for Digital Storage Media at up to about 1.5 MBit/s" Status: International Standard IS-11172, completed in 10.92 MPEG-2: "Generic Coding of Moving Pictures and Associated Audio" Status: Comittee Draft CD 13818 as found in documents MPEG93 / N601, N602, N603 (11.93) MPEG-3: no longer exists (has been merged into MPEG-2) MPEG-4: "Very Low Bitrate Audio-Visual Coding" Status: Call for Proposals 11.94, Working Draft in 11.96 Q: MPEG-1 is ready-for-use. How does the standard look like? A: MPEG-1 consists of 4 parts: IS 11172-1: System describes synchronization and multiplexing of video and audio IS 11172-2: Video describes compression of non-interlaced video signals IS 11172-3: Audio describes compression of audio signals CD 11172-4: Compliance Testing describes procedures for determining the characteristics of coded bitstreams and the decoding porcess and for testing compliance with the requirements stated in the other parts ===
