Hello everybody, I sent something about this before, but this bug is still there, so... If you call ov_time_seek(vf, 0); it will fail, returning OV_EFAULT (from ov_pcm_seek_page). I think this must be a bug, because seeking to 0 seconds *should* be OK. Another thing, when ov_time_seek fails with OV_EFAULT, you cannot continue playing (because of the goto seek_error). This is not clear from

Dear R People: I'm working on a project that will pass a matrix from an R function to a C subroutine. I tried to write the following: #include<R.h> #include<Rinternals.h> void lu1(int *n, float *a, float *b, float *ab) { int i,k,j,p,na=*n+10; float sum, l[200][200],u[200][200]z[200]; for(i=0;i<na;i++) { for(j=0;j<na;j++) { l[i,j]=0.0; u[i,j]=0.0;

Hello I'm testing SPEEX on embedded board using ARM7 (Atmel). ARM7 don't have floating point so I'm using FIXED_POINT. Unfortunately the encoding speed is about 5 times slower then necessary for real time. ARM7 is slow for 16/8 bits operations. The sequence: static inline spx_word32_t compute_pitch_error(spx_word16_t *C, spx_word16_t *g, spx_word16_t pitch_control) {

I’m running into a problem with my application crashing when I make a call to the ov_time_seek() function. The call includes the OggVorbis_File and it is indeed seekable, as I first check that using the ov_seekable() function. Everytime, however I try to seek forward, the application dies with a core dump. I’m working with the example from the “VorbisFile Documentation” site. The application

Hi, I need to know if it is possible to seek the Speex stream. I want to have an ability to seek in time, just like Vorbis does. Vorbis has function "ov_time_seek" and I want something like this from Speex. Is this possible? Thanks for any reply.

Hi, Gang: I remember there were different voices when you check-in the code. I agree with them although I didn't reply your mail in open64's mailing list. In the transformation you illustrate, it involves two operations: 1) promote WHILE-loop into DO-loop (i.e noncountable loop to countable loop) 2) get rid of trip-count dec/inc and compare. 1) is irrelevant to HW loop.

I am the designer for open64 hwloop structure, but I am not a student. Hope the following helps: To transform a loop into hwloop, we need the help from optimizer. For example, while(k3>=10){ sum+=k1; k3 --; } into the form: zdl_loop(k3-9) { sum+=k1; } So, we introduce a new ZDLBR whirl(open64 optimizer intermediate) operator, which represents the loop in whirl as:

Hello, I have written the following code. when i try to vectorize it through opt. i am not getting vectorized instructions. #include <stdio.h> #include<stdlib.h> int main(int argc, char** argv) { int sum=0; int a=atoi(argv[1]); int b=atoi(argv[2]); for (int i=0;i<1000;i++) { sum+=a+b; } printf("sum: %d\n", sum); return 0; } i use following commands: clang -S -emit-llvm

The changes to vorbisfile that I suggested earlier have now been committed - this is mostly a merge of my code with a similar patch from Martin Vogt (thanks Martin). The old ov_open() interface remains untouched - and for many people, this is all you'll need to use, ever. It now calls the new interface with appropriate arguments. The new ov_open_callbacks() function adds an extra argument to

I want to vectorize the user given inputs. when opt does vectorization user supplied inputs (from a text file) will be added using AVX vector instructions. as you pointed; When i changed my code to following: int main(int argc, char** argv) { int a[1000], b[1000], c[1000]; int aa=atoi(argv[1]), bb=atoi(argv[2]); for (int i=0; i<1000; i++) { a[i]=aa, b[i]=bb; c[i]=a[i] + b[i];

Hi R developers, I am new to this forum and hope someone can help me with .Call in R. Greatly appreciate any help! Say, I have a vector called "vecA" of length 10000, I generate a vector called "vecR" with elements randomly generated from Uniform[0,1]. Both vecA and vecR are of double type. I want to replace elements vecA by elements in vecR only if sum of elements in

Hello, If you call ov_time_tell(vf) after a ov_time_seek(vf, 0), it returns Not A Number (Negative Infinity). I tested this only using Win32 MSVC++ 6 Dynamic, Release. Does it also occur on other platforms? Is this the right behaviour? Seems wrong to me. Anyway, it caused a range check error in my code, and a divide by zero when I disable range checking (I'm using Borland Delphi 5). I

Good day. It seems vorbisfile has a bug. There is a such string in ov_time_seek: ogg_int64_t target=pcm_total+(seconds-time_total)*vf->vi[link].rate; It is not accounted type convertion between double and ogg_int64_t. E.g. if I convert 440267'th sample (44100Hz source) to time: double dSec = 440267 / (double) 44100; and then try to seek dSec: ov_time_seek(pOVFile, dSec); the resulting

i removed printf from loop. Now getting no error. but the IR doesnot contain vectorized code.

even if i make my code as follows: vectorized instructions not get emitted.
