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:

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.

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

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).

Theora vs. Nullsoft NSV
How does the Theora project differ from Nullsofts NSV project?
Other than the obvious fact they use mp3....

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?
Thanks...

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.

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.

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:

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?

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?
