Hello all I want to compile a test suite of ogg vorbis streams which can help me test the various features of the Vorbis Decoder that I am porting to ST200 VLIW processor. I started from the Tremor codec and want to test all the parts of my ported decoder for correctness (bit match) with the reference. Can anyone guide me to a Vorbis encoder which allows me to change the encoding configurations

Hello all Could you please tell me if and how Vorbis is used for the audio in DivX? Is it still encapsulated within ogg container format in DivX or does DivX contain raw Vorbis encoded packets? Any clues or pointers would be helpful. Thanks & regards ~previr

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

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.

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

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

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 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

I added a new function to libvorbis that allows lossless changes of the volume to an vorbis_block. This can help to get reasonable loudness on hardware players that do not support the Replay Gain tags. int vorbis_gainadj(vorbis_block *vb, ogg_packet *op, float* dbgain); dbgain contains the relative adjustment for each channel. The trick is quite simple. I adjust the first 2 floor values for

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

Hi, I'm a Pocket PC developer and have created a audio translator application on this platform. I currently make use of an MP3 decoder engine, but due to heavy licensing fees I'm thinking of switching over to a patent free format. Vorbis presents the best approach. I read that tremor decoder has been especially optimized for embedded devices. I'd like to make use of this and

Hi All, I am planning to implement Ogg Vorbis Decoder on a 24 bit DSP. I have following doubts: 1) What is min and max bitrate? 2)What is max Audio Packet size ? 3)What is the max size of setup header? 4)Any idea how to start for making a 24Bit fixed point reference code? Shall I start with floating point or Tremor or Tremor Low Mem Version? 5) What window sizes in Ogg Vorbis are normally

Hi, While following the developer mailing list, I came across "tremor-lowmem" version. I did some search of it in Xiph.org and "tremor" source code but wasn't able to find it. I would like to know if there is any separate thread for the "tremor-lowmem" version as we are working on the fixed point implementation of Vorbis code and we are looking forward for

We've made a little change that changed the output of vorbis is there a way to check the accuracy of the output against the original output? I also asked this question in the irc ... Thanks, Tal.

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

I have this assignment to do and after ten hours of constant trying my eyes ache and i give up.. all i'm able to get is this plot please help me these are the commands i have used till now read.table(file.choose(), sep=";", header=T) read.table(file.choose(), sep=";", header=T)->areas melt(areas,id=c("Year","State"),m=c("Rice"))->

Hi, Tis is kiran. I ve a project in which v have to cross compile the source code of ogg vorbis audio decoder onto EDB9302 ARM board.. Can u pls tell me the steps how to proceed or lead me to a source whr i can find the procedure... Thank u -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi vorbis experts! I'd like ot write application under Symbian that use theora as video codec & tremor as an audio one. I played at first with libogg & theora on PC, then successfully ported them both. Next I decided to port Tremor but I found that it use its own files from Ogg library. The API is almost identical, so I tried to bind the Tremor with upstream Ogg library (it actually
