similar to: .ogg extension and Theora

hi guys, i'd like to have your opinion on using ogm or mkv containers for theora videos. since you recommend ogg containers for theora and vorbis officially i've been insisting on using .ogg. but for example eightsoft put ogm instead of ogg for theora on the last build of "super" and i send an e-mail to them about this issue. and i didn't get the whole idea on the

Hi All! I have some troubles with OGG and GStreamer: 1) When I parsing ogg file with ogmdemux element, I recieve (in "pad-added" signal callback) video pad as "application/x-ogm-video", but not as "video/something". And that why I can't link It to the oggmux element and write new OGG file :( 2) I'am using "playbin" to play media file, but It

Well, actually most OGM files do have a subtitle track, often in multiple langauges. Also, re 2. Keyframe seeking in OGM is generally a bit rough because ogm files can contain almost any codec as the video track, usually xvid or divx. re 1. As a general rule you shouldn't be trying to make any more ogm files :) So chances are the ogg muxer is not accepting the connection, because it

Hi all, Xiph aims at developing open-standards media formats. Though xiph.org tells about vorbis/theora/flac/speex, nothing is mentioned about container to use (that is ogg/ogm). I have a few questions Is there a difference between ogg and ogm? I guess its only the extension that is different and everything else is same. Some tools (like ogmtools) are available to create ogm files. What is

I want to install mplayer but my GCC is 4.0. can not compile the mplayer. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos/attachments/20100824/86c613fd/attachment-0002.html>

Theora and Vorbis both uses same extension .ogg. I know ogg is a container, just like avi. But in my opinion video and audio files should have different extensions (using .ogv can be a nice idea). To a media player it doesn't matter what extension a file uses, but to a human who does a ls in a directory full of media files having different extensions will help a lot. I know one can use file

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!

Alright folks, here's the solution. 1) Keep extensions to 3 letters for audio & video. Except for special situations where the user might be doing a codec specific name. Since the official extensions are 3 letters, those can always be used on any 8.3 device. 2) introduce a new extension .OGV for ogg container video. With a strong preference for Xiph only codecs. (If you want 3rd

I'm trying to create files that contain a video stream, one or more audio streams, subtitles, and DVD-like chapter information. ATM, I use ogm containers that can handle all this. But although ogm is supported e.g. by xine (including chapters), it seems to be an unofficial hack. Is that correct? I'd like to move to ogg containers, since ogm doesn't support theora videos. My final

To be honest, I just added Theora because I needed a simple way to multiplex streams. Also, it'd

Hi! I made an ogm file with ogg audio and divX video. When I play it, sound and movie are not well synchronous (I played it with WMP and ashampoo). What can I do? NB: I know that this problem does not come from the audio and the divX video files, since when I make a mp3/divX avi file, it works.

Hi, I've now uploaded the preliminary documentation on the xiph wiki: http://wiki.xiph.org/index.php/OggKate Attached is the current source tree for the libkate library. The tarball also contains the patch to oggmerge (which you will need to apply if you want to merge Kate streams with Vorbis or Theora streams) and the patch to MPlayer to use Kate streams as subtitles. An example is

Hello all Could you please tell me if and how Vorbis is used for the audio in DivX? Is it still encapsulated within ogg container format in DivX or does DivX contain raw Vorbis encoded packets? Any clues or pointers would be helpful. Thanks & regards ~previr

hi, I'm the developer of a video software "Elektronika", and I want to add ogm support. do you know where I could find information about the ogm file format. thanks, renan aestesis.org

Hello, I need to demux video files created with ffmpeg2theora 0.28+svn18147 I have ogminfo v1.5 and getting this error (ogminfo.c) OGG stream 1 is of an unknown type (bad header?) (ogminfo.c) OGG stream 2 is of an unknown type (bad header?) (ogminfo.c) (a1/serial 1092562206) Vorbis audio (channels 2 rate 48000) Is possible, that ogminfo is older then ffmpeg2theora ? Or what can be the reason?

Hello, It's been a little while, but I've got some new info. I've tried doing this with Mencoder, ffmpeg, VLC player, and AVIdemux. None work. When I try to either convert a theora(ogm/ogv) file to AVI, while using?variations of "-vcodec copy" to keep theora comression, or just compress an AVI with Theora, it does one of several things, depending on settings and the program

Hi all, I just did a brief test with 3 different codec combinations: 1) ffmpeg sorenson/flv, mp3 audio in flv container 2) ffmpeg h264/vorbis audio/matroska 3) ogg/theora/vorbis using encoder_example Here are the results: 10721201 2010-10-16 14:46 origem1.flv 20731108 2010-09-13 23:04 origem1.mkv 33101703 2010-10-03 11:24 origem1.ogv as you can see, flv wins hands down, and it doesn't look

In many countries, a movie contains three parts: video, audio and subtitles. An OGM container supports all the streams, and it's possible to add another audio or video stream to it with ogmmerge. That is the difference between OGG and OGM. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a

Hello everyone! This list may not be entirely appropriate discussion, but in the lack of ogg@xiph.org or ogg-dev@xiph.org this will have to do. I've been thinking for a few weeks that Ogg needs a simple text stream (read subtitle) format to go along with theora. This is important, because otherwise I can't transcode fellowship of the rings while keeping the elvish-speek, unless I render
