similar to: ogg pic format (again).. here's why

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

To briefly summarize, mng is an animated image file format from the people who designed png, and is essentially a multiframe extension of the same. png (pronounced 'ping') is a format developed by a group of volunteers as a replacement for

Will there be an ogg picture format as well ? Would be nice.. Would be great with an open-source pic format with alpha-channel, layers, fx, etc. :) .. btw, http://burnallgifs.org/ about those tags i talked about in the prev post, some better names would maybe be 'NEXTGAPLESS' and 'THISGAPLESS' or something like that :) Gerry --- >8 ---- List archives:

Dear R-helpers, Is it possible to create a type of 'movie' in R based on the output of several figures (e.g., jpegs) via the plot() function. I obtained dynamic results with the plotting function and would like to save these as a movie (e.g., avi or other formats)?

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

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

I'll get to the technical aspects of these letters in a bit; they require an a little thought and I'm knee deep in the codebook engine right now... > <RANT> > > I personally favor the MNG approach over the Ogg strategy because of the way > the licensing agreements read.

First of all congratulations on reaching alpha status. I was wondering if you people are implementing multiple layer support into the codec. I don't know if it should be in the container (ogg) or codec (theora) but perhaps the syncing requires at least support in the codec. For example a commercial: a cup of hot chocolate with steam escaping. Little action, low bandwidth. Then comes the

Hi, I would like to create a movie out of a lot of png files. Using mencode I would do have something similar to mencoder "mf://*.png" -mf type=png:fps=5 -vf spp,scale -ovc lavc -o output.avi but I want to have an ogg format. I.e. an ogg movie How to do it? convert can convert the pngs to an mpg but not to an ogg! convert: unable to open module file

Hi all, Just thought I'd share something I discovered last night. I was interested in creating animations consisting of a series of plots and after finding very little in the usual sources regarding animation in R directly, and disliking the imagemagick method described here (http://tolstoy.newcastle.edu.au/R/help/05/10/13297.html), I discovered that if one exports the plots to a

I know this probably transcends the scope of the current aims of Ogg video, but one thing I'd consider extremely useful is a lossless video compressor. There are a few of them out there (e.g. PICVideo's lossless wavelet codec) but I've found no free ones so far. The primary use would be for storage of video clips that would be too cumbersome to store as raw frames but still require

Hi all, I am trying to set up the codecs table in the wiki and we have played a bit with Dirac to find out what existing tools write into the header. The Schroedinger implementation by Fluendo uses (or used to use) "KW-DIRAC" as the identifier in the Ogg header. "BBCD" is the identifier of each of the Dirac data packages. More recently, I read that the Dirac Sequence header

I was under the impression that 8 was the limit. Thus the extra white space JM adds on Speex and CELT magics. I may be wrong, though. > So it's 7 for Vorbis and Theora, 5 for FLAC So

Hi List, Just batting a few ideas around here, but would it be possible to include in to the codec, estimation for common video artifacts that occur in the analogue world? For example, anything that's gone through a composite stage will likely have dot-crawl and false colour - if we can recognise this effect in the encoder, we can treat it as a special case. Other artifacts that come to

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)

Hi, The minimize plugin conflicts with Animation. For example, it doesn't let Animation draw shade animations, and interferes with other window event animations. The animation plugin now minimizes the relevant effects to taskbar, so using the two plugins together doesn't make sense anymore. Moreover, by default Animation is off, Minimize is on, and when users enable Animation, naturally

I'm playing the "Honey" movie (both Honey-small and Honey-large) and I notice significant slowdown during periods of lots of motion (when the camera shakes, when the first man hops into bed, when people turn around and approach the camera, etc.). The audio plays smoothly all the time but when there is a lot of motion, the picture freezes and resumes when there's less motion.

Hi everybody, I was just wondering if there is a DRM (Digital Right Management) solution to use with ogg vorbis. Any information welcomed.
