With both vorbis and libmng nearing stable status, I've been thinking about combining the two to make a real multimedia format. What would be involved in embedding mng in an ogg bitstream? From what I've read of the documentation, there doesn't seem to be any codec-enumeration system. Do we just interleave the packets and let the player guess based on the headers which codec to try? I

I've added ogg support to my player app. Now I'd like to be able to write/read album cover art (jpg, png, what ever) out of the ogg file and display it, as I do with mp3s. This assumes that an album cover art picture can reside inside of an ogg file. I've read through the vorbis.com/faq.psp as well as the list archives and haven't found any direct answers. The section on comments

This is a proposal for Ogg MIDI streams. It will also help other stream additions to Vorbis, as they should follow a similar model. Ralph has done much of the work on this, and also is working on MNG Ogg streams. Background ---------- I was contracted to do this work, so even if you can't think of a use for this, there is one ;) Basically with midi in Ogg, we can have a synchronized

Hi there, I'm not sure what the right place would be, please direct me to where is most appropriate if not this list. I am currently working on a codec designed for karaoke and text information, to be embedded in an Ogg container. It includes text, motion information, and style/placement. At the moment, the bitstream design is still in flux, but draws heavily from Vorbis and Theora, while

Ok guys, I just committed the Ogg MIDI code to ogg-tools/oggmerge. You can now make synced vorbis+midi Oggs, but there is (not yet anyway) a tool to play such files. Have a look at the code, and let me know if you see anything major. Adding new media types for merging should be trivial, and you already have two examples (the vorbis one is VERY simple and the MIDI one is much more complicated)

FWIW, I've just imported my mng-over-ogg code into xiph.org cvs. There are currently too tools, both under the new 'ogg-tools' module: 'oggmerge' is intended to multiplex files of various formats into a single ogg bitstream. Currently it only creates degenerate mng-over-ogg files. Next step is to add support for multiplexing with ogg vorbis files, and jack will likely be

Here's a question I have: My understanding is that OGG is a 'containter' format, allowing for multiple streams of multiple types, of which Vorbis is only one. My question is this: Is it feasable (and, considering licencing, leagal) to create an .ogg file that contains, say Indeo or Cinepak video? (In other words, use the ogg bitstream to store the data rather than .avi).

Good evening, I've just read the theora specs and I was wondering how theora bitstream is multiplexed with speex or vorbis audio in the ogg container. I'm looking for a reading (tutorial or specs) about ogg multiplexing. Manuel. -------------- next part -------------- An HTML attachment was scrubbed... URL:

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

Hello, I have in the past few days played a bit with libogg. My goal is to learn enough of it to try wrapping current tarkin codecs into an ogg file, with vorbis sound eventually. I did work on a small program which allows you to easyly (de)multiplex Ogg files in a way which seems to conform to the docs. You can do things like: oggmux in1.ogg in2.ogg in3.ogg - mux3.ogg oggmux mux3.ogg -

Hi John, I'm forwarding this email to the relevant developer lists at Xiph.Org, where the format was created and where the experts gather. I'm certain there is a design reason for putting the bos pages of all logical bitstreams together at the start. My guess is that with digital media you usually have a delay time for setting up the decoders for a specific format and by clustering

We have new drafts of CMML 4.0 as a text codec and ROE as an xml stream abstract, subsuming the authoring support in CMML 3.1 and earlier. Another thing we talked about at LCA is a how to specify relationships between the various streams in Ogg so that a server, muxer or player can make intelligent decisions about the contained tracks. The general idea is to use the (http-style) Message

Hi, I recognize the main name behind CMML here :) Does the redesigning of CMML allow overlapping clips ? This is the main reason of my current ramblings about seeking. While karaoke was one of the initial goals behind kate, it is just a way the format can be used with (in fact, the format itself does not refer to karaoke at all, but styles and motions). At the moment, it is a fairly versatile

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

Dear Ogg Developer As written on my subject, is it possible to do on-the-fly video multiplexing with OGG? I'm doing my final project in my college, and i want to build a system which has three live videos from cameras, then i want to transmit those video in single stream. The Receiver can choose which video that receiver want to see. I tried using oggz and piping in linux, but it no works.

Hi, I think we can start by defining an official field name at www.xiph.org/vorbis/doc/v-comment.html which is used as a file system link to an existing image file. I suggest the field name to be "PICTURE". What is ogg MNG? Is it a container format for PNG files which should be embedded in OGG files? If I understand correctly, the picture would be placed in a different logical stream

Hi, I have a question regarding Ogg’s multiplexing process. Let’s say we have two logical streams, S1 and S2, which need to be muxed together into one physical stream. On logical stream S1, we have a packet that’s too big and needs to be split into two pages, P1 and P2. On the other hand, logical stream S2 also has a page Px that needs to go out. When these 2 logical streams are muxed together,

I have a question about Ogg. (which, ironically, means i'm posting to the wrong list. I don't know of an Ogg list though, and if i'm posting to the wrong list, please inform and forgive me) A while back I read how some of the developers had added MIDI support to the Ogg stream format. While just in early stages, this reminded me of a thought that had been passing through my
