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

I read some lines in libvorbis/include/vorbis/codec.h: /* vorbis_block is a single block of data to be processed as part of the analysis/synthesis stream; it belongs to a specific logical bitstream, but is independant from other vorbis_blocks belonging to that logical bitstream. *************************************************/ My question. Does this imply that vorbis_analysis

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,

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.

Using libvorbis (1.3.5) I wish to extract the raw vorbis packets.  I've built some simple code on the excellent libvorbis API overview on the xiph.org site, but the example relies on the ogg_packet struct for final output and input to decoder, and shows now examples on how to do without it. Taking a look at the vorbis_bitstream_flush() function, which in the overview is the last step before

I am trying to write a media player in c# which will be able to play .ogg video files which contain Theora video and Vorbis audio streams. Currently I am using LibOgg and LibTheora (via a SWIG generated wrapper). This currently is able to decode the video and output it to the screen. I would like to use LibVorbis to decode the audio stream. Looking at the documentation it looks like I have to use

Hi, This mozilla bug report is a crash triggered by a Vorbis file with corrupt headers: https://bugzilla.mozilla.org/show_bug.cgi?id=481601 The patch to fix the crash adds a new vorbis_dsp_init() function to libvorbis, and calls that from fs_vorbis_init() in libfishsound: https://bug481601.bugzilla.mozilla.org/attachment.cgi?id=366150 The public function it adds is: void

Per Monty's suggestions from a while ago, I have [finally] gotten around to playing with different schemes for parallel oggenc. Monty's main suggestion was to have a single thread loop over reading samples and calling vorbis_analysis_blockout(), and then queueing up the resulting blocks to be processed through vorbis_analysis() in other threads (in parallel). To verify that this works, I

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

Here are some very small header patches to make header dependencies less visible. If other developers would like to use cxref to produce cross-referenced html source, I can post a Makefile to do this. Sorry about not being able to send it as an attachment. You can also get it at http://216.164.32.243/~kruus/vorbis/ for now, but my net connection is slow. 'cxref' suits my purposes,

Hi (hope I am in the right mailing list!) I really can't figure out how to use Vorbisgain in OggdropXPd - it doesn't seem to work so far. Can Someone pls. explain detailed (steps) what to do when using Vorbisgain in OggdropXPd? I understand the settings for Vorbisgain are in "decoding options"... why? What I really want is the function of Mp3Gain on Ogg-files, and I thought

I've just Replaygained several of my Vorbis albums with Vorbisgain, ranging from 80's metal to present day soft rock. What I don't understand is why does Vorbisgain actually make all tracks QUIETER? I see an average of -7db on most albums. And after that, not only are they substantially quieter than my MP3s (which is a pain), but it also fails to really "even out" the volume.

Ah, OK, I understand where you're headed now. The libvorbis API is different than

I'm not sure that this is not my fault, but here it goes: I'm trying to encode a 22 kHz Mono stream. I started with the encoder example and made it take dynamic channels etc. This is how I init it: vorbis_info_init(&VorbisInfo); vorbis_encode_init(&VorbisInfo, 1, 22050, -1, 128000, -1); then I get a crash in: _vp_quantize_couple(vorbis_look_psy * 0x01e6a6ec,

Is an "official" vorbisgain source tarball available anywhere for *nix? Seems like everything I've found is a pre-built windows binary... Thanks in advance! Regards, Owen G.

Nothing on a branch yet; I'll be building a temp branch for my changes soon. First, I'm eliminating ordering dependancies in vorbis_block structures. They'll be totally sepreate and vorbis_analysis won't have a global state in vorbis_dsp_state that requires them being done in order. That way, a parallel-threaded encoder can run multiple vorbis_blocks through multiple

have linux install on my laptop, and decide to clean up my music collection, found allot of my music that has replaygain tags, and allot don't. How would I fix the ones that don't have any replaygain tags, ? have flac and flac123 ogg ogg123 vorbistools and vorbisgain..etc, all installed, can play music fine, but when I hit a song, that doesn't have replaygain tags, need to turn down

I'm considering patching my copy of ogg123 to support vorbisgain tags. Is there any interest in folding this sort of patch into the main line ogg123? Has anyone done this already (or to another command line ogg player)?

Are the ogg/vorbis programs updated to v1.0.1 ? OggDrop for example ?
