similar to: use of 'long' in vorbis structures

(i hope this is correct m.list) Hi, there is a small compiling problem for mingw when compiling on libogg.. in include/ogg/os_types.h : ogg_int64_t, ogg_int32_t, etc are defined correctly on cygwin and MSVC/Borland but not on mingw... i have attached a patch that will fix this problem (i hope it attaches correctly) thx, Nehal --- os_types.h.old Fri Jul 19 02:25:52 2002 +++ os_types.h Tue

Hi I'm evaluating Theora for a video communication system and would like some info as to what the following struct members (from the theora_info structure) do and what values one should pass to them: If there is some documentation somewhere that I've missed, please direct me to it. ===== Extract from theora.h ===== int quality; int quick_p; /* quick encode/decode */

Hi, The attached patch changes occurrences of serialno to use the type ogg_int32_t, rather than int, as int can be too small on targets where it is only 16-bits.

Hello, I'm interested in getting vorbis up and running on the PlayStation 2. I'm an official developer, not a ps2 linux developer, but the issues should be roughly the same. I've gotten the code to compile but our setup (intentionally) doesn't have libm so I'm seeing references to several double-precision math functions. Some of the issues I'm seeing: - As reported on

Hi all, Just a stupid question The IDctSlow function on file idct.c has this line : ip[0] = (ogg_int16_t)((_Gd + _Cd ) >> 0); The ip[0] , _Gd and _Cd are of type ogg_int32_t My question is: The result of (_Gd + _Cd) can be a number with more than 16 bits ? (yes, it can be because they are int32, but the algorithm could guarantee something about that... I dont know...) If

I have no objection to the API in itself, but could the API and structure only use the ogg fundamental types (like ogg_int32_t) or even better the C99 official types (like int32_t) because at the moment there is a real mix of types used for the occurences of serialno (long, int, ogg_uint32_t), beos, eos, ... Andr? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi there. This patch changes the block selection to quantify error based on the sum of the squared differences of the pixel values rather than the sum of the absolute differences, the former conventionally and statistically seeming like the preferable thing to do. The patch also const'ifies some parameters (which doesn't affect code quality on recent GCCs but might help on older/ other

I spent a fair amount of time optimizing tremor for the PS2, mostly by using dual-pipe multiplies in the X[N]PRODnn and the window apply code. Then, just for kicks, I re-enabled _LOW_ACCURACY_ and lo and behold it was still substantially faster. I also got some gains out of tremor by changing the longs in cookbook and sharedbook to ogg_int32_t's like I did for vorbis. I think _LOW_ACCURACY_

Hello, As we discussed with derf some time ago, it seems it is not neccessary to enforce "forward" order of dct_coeffs. This patch gains .99366902855226196000% so approx 1% speedup.

Hi, Can anyone familiar with data alignment issues on ARM give me some advice about this bug?: https://bugzilla.mozilla.org/show_bug.cgi?id=483912 The relevant code is in liboggz HEAD at: http://git.xiph.org/?p=liboggz.git;a=blob;f=src/liboggz/oggz_auto.c;h=ebb825c348298dc352a54d6925ce74ed707bbc3a;hb=HEAD#l138 cheers, Conrad.

hi , As i had stated before , i am having problems with ov_open() which returns -132 error. i have uploaded the project file in rar format. it is a vc++ project file, can someone please check out the error and tell me where i am going wrong... http://sr2.mytempdir.com/89384 Thanks and regards sam

Hi all, I'm porting the Tremor code to an ARM platform. Unfortunately, we didn't use the low mem branch code for CPU performance consideration, and now I find the memory use in it is huge for the embedded system. After looking into the code, I found the header parse, especially, the codebook unpack part takes a lot of memory. Tremor decodes the codebooks to a cache to store

Hi guys, This is my first post, I?m a brazilian programmer and I think speex is a great project. :) I'm working on a free software project and I was planning to use speex on it. I have used the java speex version in another project and that worked well, and this time I was planning to use a JNI version to get the latest features. ok, lets get to the point. :) I would need to mix some audio

Often it is useful to keep a "codebook" to document the contents of a dataset. (By "dataset" I mean a rectangular structure such as a dataframe.) The codebook has as many rows as the dataset has columns (variables, fields). The columns (fields) of the codebook may include: ? variable name ? type (character, factor, integer, etc) ? variable label

Hi, I am a bit confused on how code-words are derived from the codeword lengths. I will appreciate if someone can point me in the correct direction. I will take the example of an actual codebook that i found in a valid vorbis encoded file as shown below. [SK] +------Codebook [0] -------- [SK] Codebook Dimensions = 1 [SK] Codebook Entries = 8 [SK] Unordered [SK] 1, 6, 3, 7, 2, 5, 4, 7, [SK] NO

I've been trying to get some data from the National Survey for Family Growth into R - however, the data is in a .dat file and the data I need doesn't have any spaces or commas separating fields - rather you have to look into the codebook and what number of digits along the line the data you need is. The data I want are the following, where 1,12,int means that the data I'm interested

heh...:) maybe I?ll just answer "the number is 42". ;) well... some guys did mixing using *G.722 *encoded frames... maybe we could ask them: 8P http://ieeexplore.ieee.org/Xplore/login.jsp?url=/iel5/4054516/4054517/04054870.pdf?isnumber=4054517&prod=CNF&arnumber=4054870&arSt=2045&ared=2048&arAuthor=G.+Agnello%3B+R.+M.+Dansereau and a little off-topic, but fun for

Anexed is my function for reading codebooks and the Vq Table. My problem is: I read a codeBook number of 41, so i called this function above 41 times. The firtst time, the sync patterns (BCV) is alligned correctly, so it reads correctly. the sencond time it is executed, the patter is not there anymore and there are only 8 BCV in my file. function fReadBits1 is the same as the ogg's read bit

Hello kind developers, I am planning on creating a steganographic extension for speex/CELP. Since speex/CELP is lossy, there should be quite many bits that one can use for hiding data. I'm familiar with the principles of CELP (two filter loops, one for pitch, the other for formants, let the raw speech frame run through those filter loops, take residue signal, map it on a codebook entry,
