similar to: ogg, ogm or mkv

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?

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

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

[snip] What if, at least for Windows, someone wrote a simple application which when associated with .ogg files and an .ogg file was opened simply read enough of the ogg stream to identify the type of content and then

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, 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, 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

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

Is there a program currently available that will correctly mux a52/ac3 streams and theora streams into an ogg container? I've tried oggzmerge, and it will mux ac3 into ogm and correctly create a new ogm from an existing theora file, but it doesn't seem to put the two together correctly.

Hi, in the past two days I wrote Python bindings to libtheora: http://github.com/certik/python-theora Currently it can read any ogv file (that seems to work quite well) and also encode to ogv (this mostly works, but there are some subtle issues to be fixed, I suspect I still have some bug in the way I half the dimensions of the Cb and Cr planes, so when you read ogv and write ogv, the resulting

Hi everyone, I face a problem trying to encode a mkv file into theora using directshow filters I have a mkv file containing only video encoded in YUY2. I use the DirectShowNet Lib V2.1 ( <http://sourceforge.net/projects/directshownet/files/> http://sourceforge.net/projects/directshownet/files/) I use the matroska splitter directshow filter v1.0.2.9 (

Hi, I have two questions 1) How can I convert a raw miniDV file to ogg? I have made a continuation to the conference I organised two years ago on gravitational waves Astrophysics and Relativity and I have a lot of miniDVs to be converted to ogg. I think I have seen the information before but, after looking for some one hour, I have given up. And, by the way, do you know how to dowload the file

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

I mentioned it in the #theora channel a few days ago but here it is with a more permanent url: http://www.firefogg.org/make/advanced.html & http://www.firefogg.org/make/ These will be simple links you can send people so that they can encode source footage to a local ogg video file with the latest and greatest ogg encoders (presently thusnelda and vorbis).

Hi guys, the SUPER codec by Erightsoft http://www.erightsoft.net/SUPER.html contains lots of GPL and LGPL code: mplayer, ffmpeg, x264, musepack, theora, which they admit and give credit for. Still, their product is proprietary, and they insist on it. I tried to get the source through their forum, but they of course won't give it: http://www.erightsoft.net/Supforum.html I'll forward

if i want to play a .ogg file, should i have the theora codec installed in my machine...? is theora the only compatible codec with ogg container format..? i am using Ubuntu 7.04, with the default player (Totem Movie Player 2.18.1), it is not necessary to install theora externally. why is this, with the totem player they included theora codec....? or .ogg can be play with another codec...? --

Hi, The standards for audio and video to be used by the Wikimedia projects (like Wikipedia) are Ogg Vorbis and Ogg Theora. The use of Ogg Vorbis files is growing fast. For now the use of video is still very limited. The problem is that an audio and an video file looks the same because of the same file extension. This is very annoying because you do not know what for file it is when you look at

hi, i am looking for a free hosting / file transfer service to share theora and vorbis encoded ogg videos. i have been making a series of contemporary art projects titled "a copyleft crowdsourcing free/open source project" with art students in gropus of 50-120. as a part of the project we want to share the video and audio content created for the project as copyleft and free/open
