Hi, Since a number of people are eager to try out the native VP3 decoder in xine, I have made a patch available, bz2-compressed: http://www.pcisys.net/~melanson/codecs/xine-vp3-decoder-patch.bz2 To work with this patch: 1) Get the latest xine-lib from CVS. Visit this page for more details: http://sourceforge.net/cvs/?group_id=9655 The module name is xine-lib, but you will also need to get xine-ui if this is your first time using xine. 2)...

...nally starting to achieve viewable results. It partially works right now. Keyframes only. And monochrome. Oh, and the picture is upside down (something I did not realize about VP3 until I let it fly just now). Anyway, here is a picture of ffmpeg's VP3 decoder in action using xine: http://www.pcisys.net/~melanson/ffmpeg-vp3.jpg One day I will have to check out that "Brotherhood of the Wolf" movie since it is my primary VP3 test vector.

Hi, There seem to be 2 sets of block coding patterns in the VP3x/Theora algorithm. Based on the comments in the code, the first pattern is used if encoder version < 6 and the second pattern is used in encoder version >= 6. None of the code to support the second pattern is ever called. Is there an encoder with a version >= 6? The code in question is

Dan, In reviewing the code, derf came across the DCSearchPoints array in QuadCodeDisplayFragments(), encode.c:696. It looks like it specifies a search order for nearby coded fragments for prediction if there isn't a nearest neighbor. However, the upper search bound is defined as *0*, so the search loop (line 917) is never executed and it always falls back to the last coded fragment.

Hi, Let's play a little game. Forget all you know, or think you know. Without any context at all, what does the following pattern make you think of? <p> X -> X X -> X | ^ v | X <- X X <- X | ^ v | X X -> X X | ^ | ^ v | v | X -> X

Hi, I have been on a documentation kick recently. I finally updated my VP3 format document tonight: http://www.pcisys.net/~melanson/codecs/vp3-format.txt v0.2: October 9, 2003 - expanded section "Reversing the DC Prediction" - added Appendix B: Theora Differences Feel free to look it over and point out any glaring mistakes. I can't wait to see how much sense it makes to me in the morning. But I com...

Hi, Check it out-- another update in the space of a week: http://home.pcisys.net/~melanson/codecs/vp3-format.txt v0.4: March 2, 2004 - renamed and expanded section "Initializing The Quantization Matrices" - outlined section "Reconstructing The Frame" - moved Theora Differences Appendix to its own section entitled "Theora Specification" - added...

...uot; and "make install" both completed successfully. So now I've got R installed successfully. Its interface is fairly intimidating. Are there some examples online that would walk me through some simple calculations/graphs? - Jack Fenner John Maindonald wrote: > > To: jnf@pcisys.net > Subject: Compilation of R under Caldera OpenLinux 2.2 > > > On Sat, 28 Aug 1999 jnf@pcisys.net wrote: > > > > > > I am attempting to compile R-0.64.2 under Caldera OpenLinux 2.2.

I have a small LAN in my basement, with my PC running RH5 Linux and a Win95 PC connected by Samba. Everything works fine, but when I smbmount a CD (burned with xcdroast) from the Linux box (CD is in the Win95 machine) I do not get the proper filenames. All files are uppercase, and the TRANS.TBL files appear to be ignored. I have tried playing with name mangling, but it didn't help. Is this a

Hi, I am making good progress on understanding, documenting, and re-implementing VP3. I have found some more deadwood in the decoder code and I just wanted to verify that it really has no place: * Version 3.3 tables: There are 2 sets of VLCs: One for v3.1 and one for v3.3. The v3.1 set is always selected. Are the v3.3 tables in production, or will they ever be? * DC Search Points: VP3

...orrectly. The change in toplevel.c is trivial (new function names & params) huffman.c is the important one. I doubt anyone has touched it in a while so I suggest you use this (pulled out of CVS in the last couple days) -dan -----Original Message----- From: Mike Melanson [mailto:melanson@pcisys.net] Sent: Tue 5/27/2003 2:55 PM To: theora-dev@xiph.org Cc: Subject: Re: [theora-dev] resolution issues <p><p>On Tue, 27 May 2003, Henry Mason wrote: > On a somewhat related note, is there any reason to > encode at dimensions which are multiples of 32 in > order to have...

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, Keep up the good work! The file sizes of Theora's output is amazing! I have just joined the list, and would like to contribute to the

Hi, I am an active contributor to the xine multimedia player project: http://xine.sf.net I would like to add FLAC support to xine. I have almost finished a demuxer plugin which will allow xine to take apart a FLAC file (nice format document, BTW) and send packets of coded audio to an audio decoder plugin. I am having trouble with the audio decoder portion. Ideally, I would like to take the

I am attempting to compile R-0.64.2 under Caldera OpenLinux 2.2. I have KDE installed but not gnome. When I ran configure, it correctly indicated that gnome is not installed. However when I then ran make, I received errors complaining that the include file X11/X.h and similar are not found. Is X11 required for R? If not, how can a work around this? I have attached the output of the
