similar to: Add vorbis_dsp_init() ?

A variation on questions that I've asked before... In working on the parallel version of oggenc (both threaded and MPI), a profiling run shows that the function vorbis_analysis() takes up the majority of the run time. This seems to be an obvious choice for parallelization -- send each vorbis_block to a different processor, and let them call vorbis_analsis() in parallel with each other.

I'm running into memory leak and read-from/write-to unallocated errors in the cleanup phase of parallel oggenc. I see in vorbis_block_clear() that it references some fields on the vorbis_dsp_state that it cached during vorbis_block_init(), and conditionally does some cleanup based on the values of those fields. Does this fact effectively mean that you can't have multiple vorbis_block

Hello all Can anyone point me to some form of description for the fields in the following structures : 1/ vorbis_dsp_state 2/ vorbis_block Thank you. regards ~previr _____________________________________________________________ Previr Rangroo STMicroelectronics Associate Systems Lab Engineer Plot No. 2 & 3, Audio Competence Center Sector 16A,

Monty -- I'm still running into problems with my threaded encoded, and I think I just figured out why. I have N threads running in parallel calling vorbis_analysis_blockout() and vorbis_analysis() to do the number crunching on the input samples. They all share a single vorbis_dsp_state -- my understanding was that this was ok; they only *read* from the vorbis_dsp_state, therefore not

libvorbis does not currently have any simd/vectorization. Following patches add generic framework for simd/vectorization and on top, add ARM-NEON simd vectorization using intrinsics. I was able to get over 34% performance improvement on my Beaglebone Black which is single Cortex-A8 based CPU. You can find more information on metrics and procedure I used to measure at

I'm having trouble tracking down why it leaks, but below is an example program which shows--using valgrind--that vorbis_info_clear() leaks memory if called before vorbis_dsp_clear(), but not if called after vorbis_dsp_clear(). Just compile and run under valgrind, using the -l switch to the example program to trigger a leak. Tested under OS X 10.7 and Ubuntu 12.04. This may be by design, or

I apologize for bugging you all again, but I've been trying to wrap my head around the encoding process and I'm about to have an aneurysm :P I've gone through oggenc.c, encode.c, and audio.c and I think I have a basic idea of what happens. I got it down in pseudocode as follows: --- 1 get parameters 2 init vorbis_comment -- vorbis_comment_init() 3 init vorbis_info --

Hi all, I tend to compile my code with all GCC warnings turned on. However, when I do this : vorbis_comment_add_tag(&vdata->vc,"ENCODER","libsndfile"); I get the following warning messages: warning: passing argument 2 of 'vorbis_comment_add_tag' discards qualifiers from pointer target type warning: passing argument 3 of

Maybe this is just from inside ETH Zurich, but I haven't seen this before in many years: for > 15 minutes now, for me and at least someone else here, - Google (incl. Gmail, calendar..) is entirely unreachable - Twitter is "connecting" and is not reached (in the browser), - three major Swiss news(paper) websites (20min, TA, NZZ) are out of reach, but "of course"

I was tinkering with Asterisk and the Festival text-to-speech engine, and wrote some short Asterisk::AGI scripts to read back live weather reports. After that, I thought I needed something more interactive to work with... Then I had a flashback to 1996, first year university, standing in the C & O club at the University of Waterloo, where someone had just pulled out their US Robotics Palm

Hi, I''d like to create my first ROR application on Heroku but I can''t deal with one step in this tutorial: http://devcenter.heroku.com/articles/quickstart I''ve spent all my day for this and I have no idea what is wrong... I cannot deal with last one in 3th part -> Create your Heroku application What I did: I''ve installed eveything what I need 1. switch to

I'm afraid this e-mail is me being lazy. I'm interested in adapting the encoder to farm out work to various machines on a network. I'm just trying to find out if this is going to be trivial. I don't know how the encoder works but from my very brief glance through the code it would appear that a state is maintained 'vorbis_dsp_state' that's going to make my distributed

Hello, I've been looking to the libvorbisfile and got into troubles when trying to use it: I need to compile it on a PalmOS and the libvorbisfile must be compiled in ARM whereas calling code is in 68K. This implies that the interface ov_open_callback is not usable because the OggVorbis_File *vf must point to something in the target architecture (ARM) whereas the caller cannot do that. As

hi - does anyone on this list know if it is possible to use the vorbis audio codec in conjunction with an AVI file?? what would it take to do this? are there any apps written for this already, that could prove this codec useful with an AVI?? I can attach MP3 to an AVI of course, but there are many playback problems (mainly sync + crappy sound) with MP3... any of you developers working on

Audacity is preparing to release version 2.0.6 shortly, so I have been doing numerous test builds. Since the last Audacity release, my development system (Gentoo Linux) has updated to libvorbis-1.3.4 and libogg-1.3.1. As a result (I think) of this, I now get link errors when trying to compile Audacity against the system copies of libogg and libvorbis (standard dynamic linkage to the system

Hi, Why do I get an error message when i'm running the "encoder_example.c" which is included in the SDK? The error occurs then the 44 bits are read and the vorbis_info struct is initiated (i.e. when the vorbis_encode_init(&vi,2,44100, -1, 128000, -1) - funcion is called. I also tried to read the data from a 16 bits 44,1 KHz stereo PCM - wave file but recived the same error.

Okay, how do I drop a changeset/patchset/tag for you folks from SVN? At this point, I have written three examples of how to use the basics of the ogg streaming and decoding in Tremor. I heartily welcome any suggestions, improvements and corrections that you can point out in the code. The examples required me to make some small modifications to the main tremor library. However, the changes
