Hi, Is there anything special I need to know about VP3's IDCT? I mean besides the fact that there are separate IDCTs to handle sparse coefficient matrices. Are the IDCT functions mathematically equivalent to any textbook IDCT functions?

Hi, Currently libvirt supports metadata in the domain XML. This is very convenient for data related to the VM, but it is a little awkward for devices. Let's pretend I want to have extradata (say, a specific port for a virtual switch) related to a device (say, a NIC). Nowadays I can store that data in the metadata section, but I need some kind of mapping to correlate this piece of information

But is there any sound player for windows that plays speex in an ogg container? One more question, besides the source code found in the speex site (like speexenc.c) can you tell me where to find source code developed in C++ (using object oriented programing) that makes it easier to write ogg files with speex content?

Hi, I've been studying the Opus code and documentation for a while and have seen it mentioned several times that Opus uses pre-skip to allow the codec to converge. What convergence are they referring to? Rate control? Energy envelope prediction after seeking? Is there a discussion of this somewhere? Also, I'm also interested in the seeking behaviour of the decoder. If, say, I want to

Hi all Currently Theora video in Matroska is not supported by Mplayer. To enable the support Michael Niedermayer has made the following proposal sometime back: http://article.gmane.org/gmane.comp.video.mplayer.nut.devel/214 Appreciate if Theora developers could comment on that. Best Regards Unga ____________________________________________________________________________________ Get your

Yes, that's a start. Ultimately, though, I'm hoping to reduce the 80ms requirement, and am trying to get a handle on what state in the decoder must converge and what complications I might be up against. I'm also only considering CELT-based encodings if that simplifies things. I know that Opus can do inter-frame energy envelope prediction, but that dependency can be eliminated by

Hi all, I am trying to test DirectShow PushSource example from the SDK with Theora encoder and Ogg muxer (DirectShow filters of course) by using GraphEdit tool. My goal is capturing the screen as video by taking snaphot bitmaps continuosly (what PushSource eaxmple does) and giving them to the Theora encoder through the DS pipeline (next goal is transmitting this video **). My DirectShow graph is

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 Vorbis has 3 "global" header packets, while generic containers generally have only a single global header per stream my proposal to solve this, would be to add a few lines to the vorbis specification to clarify how to convert between the 3 headers and the single header needed for non ogg containers currently (without any standarized way) various groups simply use their own

Dear all, As the next version of XiphQT is mostly ready, I thought it could use some more wide pre-release testing. The major change since last release is the addition of Ogg exporter and Vorbis and Theora encoders. Any feedback on how this new functionality performs (or doesn't!) with audio/video editing/producing software will really help. Also, comments and suggestions on the work of

After trying to find out what to do when no packets complete on a page... i reread the ogg spec and found this... "A special value of -1 (in two's complement) indicates that no packets finish on this page." So i searched through a few files and it appears that the muxer doesn't do this... has this been depracated ? In all cases i can find that this happens the page has the same

Why do you not want it? It is just a simple C struct to carry the packet's metadata.
