VP3 Patch For xine
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

VP3 In ffmpeg
Hi, Sorry for taking so long with this, but I finally committed a first pass of my own VP3 decoder to the ffmpeg codebase. You can browse the source here: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/ffmpeg/ffmpeg/libavcodec/ vp3.c and vp3data.h are the files in question. Attached is a message I sent to the ffmpeg-devel list about the new decoder and its present shortcomings.

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

VP3 for xine 1.0-beta4
Hi, Some of you may recall that I got the VP3 decoder working with the xine multimedia player some time ago and posted a patch for anyone else to try. I really messed up when I did that since I generated the patch against some random CVS snapshot of xine-lib. I did better this time and generated the patch against the latest release of xine-lib (1.0-beta4, released today). If you

Theora vs. Nullsoft NSV
How does the Theora project differ from Nullsofts NSV project?

VP3 IDCT
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?

Accumulating latency in nsv stream
Greetings: We have a problem with accumulating latency in a 1 fps nsv video stream; the delay is about 5 sec. when the stream is first mounted but after about 10 hours it is up to 1/2 hour and after 24 hours it is almost an hour (no frames are dropped, a client viewing the stream just sees video delayed by those amounts). I have commented-out the <burst-on-connect> and <burst-size>

Cross-Compiling VP3 lib on Linux
Hi, I have been working with VP3 for some time now. Dan Miller from On2 just told me about this list. A few months ago, I managed to get On2's VP3 source snapshot to compile under Linux, a feat that many have apparently attempted and quickly abandoned. I compiled a small console app and the results of the experiment are explained here:

VP3 Compatibility and SIMD Optimizations
Hi, A few questions: Is libtheora strictly backward compatible with VP3? Can I set it up to shove raw VP3 data through and trust it to decode the same way as On2's open source code did, loop filters and all? Also, is libtheora just supposed to be a C-based reference implementation? I was looking through the code and noticed a distinct lack of any kind of optimizations. Naive tree-based

[Ffmpeg-devel] libavcodec/vp3.c compile problem (fwd)
Hi, I don't know how much of the old VP3 codebase is incorporated into Theora. I wrote ffmpeg's VP3 decoder from scratch but eventually ported in the original VP3 IDCT function. A BSD conflict cropped up that I thought I would pass along. -- -Mike Melanson <p>---------- Forwarded message ---------- Date: Wed, 10 Sep 2003 13:06:37 -0700 (PDT) From: Steven M. Schultz

Ogg doesn't measure up?!
Nullsoft Streaming Video. Basically a video container format. Can be used for files or streaming. Though it can use any audio video formats internally currently it is just VP3/MP3 (or VP5/MP3, but that's internal only and not publicly available). Basically video for the next version of SHOUTcast. http://www.nullsoft.com/nsv/ From: "Geoff Shang" <gshang@uq.net.au> > BTW,

Proof of Concept
Hi, So it took a little while to get here but VP3 through ffmpeg is finally 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:

new patch
[standard disclaimer about my mail format] in ftp.vp3.com/theora user: vp3 pass: vp3dev theora_dbm_5-28.zip this implements a bitstream change; the header now contains a compressed huffman tree rather than the frequency counts (as discussed) pardon my inability to use diff correctly. The change in toplevel.c is trivial (new function names & params) huffman.c is the important one. I

NSV video streaming not working?
Hi there, Long time no type ;-) Im having some difficulty with streaming NSV video using NSVTools. I believe the problem cropped up before since its in svn?? Anyhooz the problem is I need the latest icecast in win32 format that has been compiled with this bugfix. Does anyone have a compiled win32 fix or could maybe help me out in trying to compile with VS2005. Many thanks everyone! Rico.

NSV Problems
For some reason using the 2.3.0 Version I can no longer stream Nullsoft Video. I have the correct tags in the config file but for some reason the server will not accept the connection from the encoder. I started up shoutcast DSP and it streams fine so I know it's not the encoder itself. Anyone else seeing this or can tell me how to fix it? -------------- next part -------------- An HTML

encoder discrepancy
the files produced by windows compile vs. Linux are indeed significantly different in size (about 140K vs. 160) However I'm not convinced all the default parameters are set the same way in the two example files. This needs to be verified to see if there really is a bug, or can the two versions produce byte-equal output streams? <p> ___ Dan Miller (++,) Founder, On2 Technologies
