Hey everyone, according to Wikipedia's 4-year-old information, there is no standard for putting metadata into an Ogg file. That metadata must be included in the codec. For example, what if I want to make a Theora movie and include information about the color space or embed an ICC profile? Or can I include general textual information, like copyright? What about timecode? Brendan

Hi, Is anyone aware of existing discussion on embedding the actual wall time (as in RFC-822 date-time) into Ogg streams of continuous or semi-continuous recordings? And any methods of addressing Ogg streams by the wall time in lieu of a standard timecode? Ideally, users would be able to take note of the wall time during an event of interest, then retrieve the segment by that same wall time

That metadata must be included in the codec. That's correct in that there's no container-level metadata. The 'mapping' specs for various sets of codecs embedded in Ogg describe how metadata is stored. >

...http://www.cdindex.org/dtd/TrackInfo.dtd, but I'm conserned that it's too specialized for video and we'll end up having a special case for audio-only files. There are a couple of general issues here. Micheal Smith suggested on irc that an important distinction to make is between "timecoded" data like audio, video, and scrolling lyrics, and "timeless" data like the production notes, or the fact that logical bitstream 12 is the pop-up-video overlay in bengalese. My proposal was that each type or instance of timecoded data be encapsulated in its own logical stream. For a...

True. > That metadata must be > included in the codec. More generally, in a stream in the Ogg file. Codecs are streams, but so are things like Ogg Skeleton. Information about Metadata has been collected together in the Xiph Wiki

Hi everyone, I'm working on a WebM plug-in for Premiere. You probably already know that WebM is a Matroska container that uses Vorbis for audio compression. I'm pretty new to the world of audio compression and need some help. You can see my code here: http://github.com/fnordware/AdobeWebM First of all, I wonder if it's possible to seek to an exact audio sample in WebM. Whereas

...ributed with extensive liner notes in multiple languages, otherwise identical. In the case of lyrics/subtitles we should create separate streams for each translation, but do we want to do that for the static metadata? Does RDF already have a way to handle this? Most of our discussion was about the timecoded metadata. The proverbial scrolling lyrics, but this must also serve for subtitles (in multiple languanges), transcripts, commentary, headlines, guitar tabulature, and so on. Our most important concern to maintain maximum flexibility. As I've said before, I think it's important to have at l...

Interesting article: "Time-coding audio files" http://www.windytan.com/2014/06/time-coding-audio-files.html The author is a signals hacker who has spoken at CCC and other events, and has determined that "There's no standard method for doing this with WAV or FLAC files". Where "this" means recording the UTC time-of-day in the audio stream, as ongoing data, as

Is it at all possible to synchronize listeners so they hear the audio at the exact same time? It doesn't matter if the source and listener is a few seconds different. Someone I know wants to send Ogg Vorbis encoded audio across a wireless LAN using Icecast to 2 LPFM transmitters on the same frequency, and they really need to be closely synchronized to prevent echo in an overlap coverage

A question about capturing videos to a Samba share... When Apple's Final Cut Pro captures video files, it pre-allocates file space on the destination volume. If you capture to a local volume that's physically attached to a Macintosh, or if you capture to a network volume via AFP (Apple File Sharing Protocol), you can see that Final Cut instantly creates a file of the

I sent a little mail some time ago asking if there was going to be an ogg pic-format, and you replied that PNG, MNG and JNG is good enough (sorry for this late answer btw).. But, consider this: The ogg video-format (tarkin ? where do you get these names from anyway ? :) ) needs a way to compress its frames. Are you going to use MNG for that ? :) .. If you had an ogg pic format, that format could

Hi Vorbis-Dev, I'm investigating various WebM/Vorbis bugs in chromium. AFAIK muxing Vorbis inside of WebM does not have an official specification, so I'm using ffmpeg's implementation to try to answer 2 questions: 1. Under what circumstances is it valid to find WebM Blocks containing Vorbis data with zero duration? (This would mean the next Block in the Cluster has the exact

Hi, I'm having issues connecting Garmin GPS 18 to COM1 on 9.1, I get nothing but silence. Identical setup works absolutely fine with Linux. I've got PPS wire connected to DCD, but that seems to make no difference on Linux, so I presume it shouldn't affect fbsd either. On Linux, I get: $ uname -a Linux ubuntu 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:16:28 UTC 2013 x86_64 x86_64
