Hi, in order to understand the Ogg Vorbis decoding algorithm, do you recommend any document/book/www? I have read those on the web page but look for something more detailed..

Hi, as we are trying to implement MDCT in hardware, we are caring now about the "n" (size of input and output vectors to and from MDCT). As I have looked in the code, this "n" is chosen from the Ogg/Vorbis stream data in info.c:_vorbis_unpack_info() which means this "n" can vary aribitrarily (as the power of 2) depending only on the value got from song data? or is

Hi vorbis-dev! I'm working with Pattara in the oggonachip project, and wondering about the implementation of mdct.c as hardware. According your recomendations about using the floating point version, I would say, we have to implement the integerized version of mdct as a core, and use the fpu only to round the input values. By doing that, you think the result would be still acceptable? How

Hi, I wonder if there is specific requirement or restriction for the decoder in order to be consider "Vorbis" compliant (or let's say, to be a "correct" vorbis decoder). I am experimenting with integerized libvorbis and the decoder delivers the audio data as following, (and compare with the floating point version below). $ tail audioout-int.txt 0290670 025e 085c 02cf 0895

Hi vorbis-dev, I'm investigating the mdct* function in libvorbis and writing a small client program to test it. I found that I have to set ARRAYSIZE when mdct_init(lookup, ARRAYSIZE) to minimum value of 62 otherwise it will segfault with mdct_backward. Is there any lower limit or it is more likely that my code has bug? Thank you very much, Pattara -- Please avoid sending me Word or

Hi Vorbis, Now I get libvorbis-rc3 + integerized mdct_backward + integerized window running. The sound output is ok. Now we have to go further on possible optimization of the code in order to have the music played realtime on our chip (LEON-Sparc). There are 2 possible ways: 1.Make everything integer, remove all floating point usage. Then we can remove FPU and can run the chip at higher

Hi, Today I tried to run my player code with the CVS libvorbis (instead of RC3 as usual) and I found the infinite loop here (lines prefixed with >> are in the loop): tatic ogg_int64_t _get_prev_page(OggVorbis_File *vf,ogg_page *og){ ogg_int64_t begin=vf->offset; ogg_int64_t end=begin; ogg_int64_t ret; ogg_int64_t offset=-1; >> while(offset==-1){ >>

Hi, I have a question about compiling Ogg/Vorbis. As I plan to have the code run on the LEON/SPARC CPU so I have to use sparc-rtems-gcc, sparc-rtems-ld, sparc-rtems-ranlib. Now, in order to compile the libs, e.g., libogg, I have to create my own Makefile like this: PROG=bitwise framing CC=sparc-rtems-gcc AR=sparc-rtems-ar RANLIB=sparc-rtems-ranlib CFLAGS=-rtems -msoft-float -Wall -W -g

Hi I'm getting frequent segmentation faults (on the order of one every hour) while listening to the stream at http://62.93.224.180:15000/radio404.ogg . This is on FreeBSD 5.3 with everything installed from the FreeBSD ports (this means libvorbis-1.0.1), but I had the same issue with an older FreeBSD 5.1 installation. The backtrace looks like : (gdb) bt #0 0x28741d88 in

I'm considering creating an ogg vorbis decoder chip for my senior project in school. At this point, my idea is to have a program (such as XMMS, ogg123, WinAMP) send the encoded ogg bitstream through a USB port to my project, which is then decoded. My project then returns the raw PCM audio, which is then handled by the player program for final audio output. I'm planning on USB as it

Hi all, I recently noticed that Vorbis shlibs export several symbols which are not present in it's public header (for a total of 85 symbols, see attach). Would it make sense to filter them via -fvisibility=hidden and -Wl,--version-script? I attached a draft patch.

Hi all, Those of you uninterested in classic MacOS as a target will probably want to skip this email. I'm revisiting this platform, trying to get music going for the game I'm working on. We're obviously using OggVorbis on the other platforms we support (osx, linux, win32). The problem is that our classic MacOS build is currently under MPW/MrC. I can compile libogg/libvorbis fine

Hello, I'm getting a KErnel Pannic every time i restart the server, what could be happening? I just make: "shutdown -r now" and the server gets Kernel Panic. I'have to go on site and press the power button Here you have my sotware versions: Asterisk 1.4.24.1 DAHDI Tools Version - 2.1.0.2 DAHDI Version: 2.1.0.4 libpri version: 1.4.10.1 WANPIPE Release: 3.5.4 IS there

OK, I did this once, several years ago, but I have to do it again, and I cant figure out what this stupid error message is trying to say. I am executing system-config-netboot trying to create a diskless client for a diskless boot I constantly get a popup, with different error messages. I try to 'fix' something, and I get a different popup. The current one says: You

Hi! I've got a 32-bit Centos installed on an AMD Phenom II X2 processor and I'm interested ni making it 64 bit instead. But I'd sure like to avoid having to go back thru the whole installation again... in part because I've got sotware RAID set up and I'm assuming that I can't do a fresh install into it without having to re-configure the whole thing. So, is it possible

Hi, I have tried to use uniroot to solve a value (value a in my function) that gives f=0, and I repeat this process for 10000 times(stimulations). However error occures from the 4625th stimulation - Error in uniroot(f, c(0, 2), maxiter = 1000, tol = 0.001) : f() values at end points not of opposite sign I have also tried interval of (lower=min(U), upper=max(U)) and it won't work as well.

Does anyone tried the Winsip sotware to test Asterisk? _________________________________________________________________ Discover the new Windows Vista http://search.msn.com/results.aspx?q=windows+vista&mkt=en-US&form=QBRE

Hi. Some times i need to build packages for CentOS, the major requeriment is build some missing module or package newer version required to run some sotware. I setup a mock build enviroment to compile packages, all is working as expected, but i enconter problem to share this work in a source repo, i try to figure out how other people are making this, in CentOS i have no idea on which source
