Supposedly On2 transferred their Video Recorder and TrueCast5 streaming server into opensource along with VP3. Theora is obviously the VP3 project, and while I can find nothing on Xiph about it, the recorder source is offered on vp3.com; but I can find nothing on Xiph or vp3.com about what happened to Truecast5. I contacted On2 about whether TrueCast5 was really going to be open source, and they

Here http://lists.xiph.org/pipermail/theora/2004-September/000619.html Andrey describe encoder structure, this like: "I see the following structure of the compressor implemented in the FPGA (Xilinx Spartan 3 1000K gates): 1. Data from the external frame buffer (FB) memory goes to the Bayer-to-YCbCr (4:2:0) converter in overlapping 20x20 tiles that produce 6 8x8 blocks (one macroblock) on the

Thank, Timothy! I add this stages. About RLE: I have one more unresolved stage. Mike Melanson wrote in "VP3 Bitstream Format..." about RLE using: "* Zigzag Ordering: After transforming and quantizing a block of samples, the samples are not in an optimal order for run length encoding. Zigzag ordering rearranges the samples to put more zeros between non-zero samples." If we pass

Hi, So I have almost completed a new VP3 decoder implementation. In the course of doing so, I have encountered something odd about macroblock coding. As a quick overview, VP3 has a notion of fragments (8x8 pixels) and superblocks (32x32 pixels, 4x4 fragments). These apply to each individual plane (e.g., a 64x64 video will have 4 Y superblocks and 1+1 C superblocks, 64 Y fragments

I have a command which returns a data fram if I am not mistaken: sc <- split(x, list(x$Category, x$SubCategory), drop=TRUE) Now I wish to get the Category and SubCategory that the data was split on. So my first attempt would be: sc[[1]]$Category[1] But that yields [1] (Unknown) 46 Levels: (Unknown) 10" Plates 7" Plates (Dessert) ... WOMEN Is all I want is '(Unknown)'.

I took the liberty of forwarding this to the Stackless Python list, since they switch stacks, and I got a response at http://thread.gmane.org/gmane.comp.python.stackless/4464/focus=4467. The upshot is that they really need the ability to allocate only a tiny amount of space for each thread and grow that as the thread actually uses more stack. The way they accomplish that now is by copying the

Hello , I know its very tedious solving problems MS has on a Linux based Software A Windows XP machine without SP1 , Worked Fine until one day , everything is so SLOW , every mouse click reponds after 3-4 minutes , this account logs to a samba PDC , If its a PDC or samba problem then why is it so slow on stuff done locally on the computer , i scanned the PC with an Updated norton , and

Just trrying to build the latest libtheora under windows. There is a VS6 project file (.dsp)... however when i try to open it and convert to VS2002 format (.vcproj) it tells me file is corrupted... Was this file manually created ? Has anyone else tried this with success ?? Thanks ! <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

Hi, I'm new to Theora and would like to propose several performance optimization using advanced instructions in x86 CPUs (SSE2-SSE4.2). There are several source files in \x86 and \x86_vc which developed using inline assembler. However this cause several maintenance problems: 1) Need to sync gcc & msvc versions 2) Only 32bit environment is supported 3) No support for newer than MMX

Hi I'm trying to make sense of the macroblock coding modes in section 7.4 of the Theora spec. The text in the specification is: (d) For each consecutive macro block in coded order (cf. Section 2.4) indexed by mbi: i. If a block bi in the luma plane of macro block mbi exists such that BCODED[bi ] is 1: A. If MSCHEME is not 7, read one bit at a time until one of

Right now the functionality is available, sometimes, from the C standard library. But embedded environments (often running a limited standard library) and server environments would benefit heavily from a standard way to specify context switches within a single thread in the style of makecontext/swapcontext/setcontext, and built-in support for these operations would also open the way for

I don´t found any patent around this but i ned help with the patents. I can´t found all patents for interlazed video and I only read the patents around MPEG , the optimization for field based video can be aplied without problem, this is compatible whih the progresive encoding and in a few scenarios they can be positive. <p>process: <p>common: -2 bits to indicate video type 0x
