similar to: Vorbis-/Speex-Audio for Movie-Archiving

Hi everyone, I have been using vorbis for ages as audio codec for archiving movies and I have always been happy with it, but now I have been thinking about two things: I) Multi-channel Up until now I mostly encoded to stereo; now I am thinking of encoding more movies to 4.0 or 5.1. I heard that vorbis does not optimize for channels > 2, i.e. that 6 channels is just stereo*3. AAC is

Hi, We would like to announce the first release of the Speex project. Speex (http://speex.sourceforge.net) is an open-source (LGPL), patent-free compression format allowing an alternative to expensive proprietary codecs. Unlike Ogg Vorbis which compresses general audio, Speex is designed especially for speech. For that reason, Speex is meant to be a complement to Vorbis. Since it is specialized

hi everyone ! since nobody answered the question in the extension-thread, i would like to ask again in a new thread: why does xiph and the theora-team not promote the matroska-format? do you just prefer ogg because its "home-made" or are there technical advantages over mkv? thanks! greetings hannes hauswedell

Today, Adobe Systems Incorporated announced[1] that they will extend their Flash platform to support the proprietary H.264 and HE-AAC formats. The Xiph.Org Foundation has previously contacted Adobe to consider extending Flash to support the Open Media formats Vorbis, Theora, and Speex. Adobe developers replied by stating it would be unwise as it would increase the file size of the Flash Player,

Hello everyone! Please bear with me, I am a complete audio-newbie, and I apologise if I am asking a question that I should know. As most of you all know, DVD's have 5.1 audio, and I want to preserve that in my voribs files. So, to ask the question : Does it support Surround sound? Thank you very much!

I tried to encode two minutes from an AVI DV file 720x480: ffmpeg latest release produces a FLV 320x240 25fps 360k video 40k audio in about 45 sec. ffmpeg latest release produces an OGG 320x240 25fps 360k video 40k audio in about 1:20 sec. ffmpeg2theora the same in about 2 minutes or more. The FLV quality it's quite good, some dropped frames maybe. I was wondering to know if ffmpeg team

hi, i want convert mixmonitor recorded speech audio from wav to mp3 or aac can you recommend your settings for speech audio? filters, noise elimination, compression ratio, ... i will probably use lame thank you -- --------------------------------------- Marek Cervenka =======================================

The news site of Germany's main public television station ARD now has some short clips in Ogg Theora: http://www.tagesschau.de/tagesschau24/ These are the "news in 100 seconds" clips, which are also available in mp4/h264. Curiosuly longer video-news are available as either flash or wmv? Regards, Hannes

Hi All, Software patents suck but but unfortunately for speech, MP3 (also still patented until end of next year) also sucks - for html5 audio served to iPhones where Safari doesn't support Ogg Opus and where bandwidth may be limited, AAC is a very attractive option. I have an AAC encoding solution for Linux but I don't have a way to tag them. Anyone know of Linux command-line tagger

Hi, I'm working on a project to add more audio formats other than MP3 and Ogg that can be streamed by Icecast. Yes, I mean streaming those formats, not converting them to MP3. These formats I'd like to add include PCM (.wav) and ADPCM (.adp). Although they are much less advanced codecs compared to MP3, they have a valid market for low-power clients. I've been working on the source

i have configuered and built libtheora with --enable-encoder but when i make install, encoder_example is not installed. why not? the object file and script are created in the examples subdir, they are just not installed... thanks for your help -------------- next part -------------- An HTML attachment was scrubbed...

FYI: After hearing about Safari 4's support for HTML 5, I played around with it and found that it will play Theora/Vorbis in the browser using the VIDEO tag. (If the QuickTime component is installed.)

Hi, there. While waiting for the encoder RC1, I will report some minor problems I experienced with Peter's Winamp decoder. First, I am using Nullsoft Vorbis Decoder v.1.11a with Winamp v.2.76 on Windows 98 SE. 1. When the buttons of Playlist Editor are extended, the part extended in playlist screen seems to be flickering when an Ogg file is being played. 2. I check the option of

Hello, Could you kindly point me to some instruction, how to encode demuxed files (.m2v and .mp2) to .ogg (Theora + Vorbis)? I was trying to use ffmpeg2theora, but I don't know, how to put two files to ffmpeg2theora (one audio an one video) and did not found, how to mux them into one file? Exist a way, how to do two pass encoding? I'm using Ubuntu Fiesty Linux. Thank you, Jiri Navratil

Hi, I'm trying to get the following project to work : * acquisition from video acqusition card using vlc * vlc transcode to theora/vorbis and sends it to an icecast2 server Using VLC to acquire from the device is working ok. I get a stream in theora/vorbis format with audio & video sync'ed. Now, when I use VLC to send the stream to my icecast2 server, the stream mounts, it is
