We are implementing oggvorbis decoder on embedded system. In that we want to have support of chaining and grouping. If somebody can throw some light on how it can be implemented, it would be gr8 help. Regards, Parul -------------- next part -------------- An HTML attachment was scrubbed...

For testing the encoder i needed test vectors. thanks for the links send by members. Those links are useful, but contain test vectors corresponding to 44 KHz only. Does anybody has any idea where i can find test vectors of other sampling rates i.e. 48 KHz, 32 KHz, 16 KHz, 11 Khz, 8 KHz. ? Thanks, Parul Embedded engineer Einfochips

We are working on OggVorbis encoder. In the porting effort we are trying to convert it to fixed point code (both 32 and 24 bit fixed point). Now the issue is how we do the testing. What should be the criteria for our testing. Does anybody has any idea how compliance testing (i.e. some objective tests) is done at encoder side? What is the criteria of testing at the encoder side? If anybody

Hi all Speexers, I've done some optimization to current SVN fixed-point on ARM9E platform. If the RVDS simulator gives the MCPS(Million Cycle Per Second) value A, then actual MCPS on real CPU will be around 2*A. I don't know what cause the big gap between the simulator and real CPU. What do you think? BR, Lianghu -------------- next part -------------- An HTML attachment was

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

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

Hi, Does anybody know how codebooks are generated in OggVorbis encoder? We are porting oggorbis encoder on embedded platform for which VQ codebook memory is hugeeee to imagine. How can we reduce that? Can we do VQ with less codebooks and if yes how? If any help available? Parul Embedded Engineer Einfochips Ltd

Hi, I've started working on libogg2 support in liboggz and Tremor support in libfishsound. I'm running into some problems with namespace clashes. Specifically, each of libogg, libogg2 and libvorbisidec (Tremor) define conflicting ogg_* symbols and declare incompatible ogg_* types in their headers. While I understand that a dedicated Ogg Vorbis decoder would only need to use one of these

Hi, I'm experiencing a serious problem when trying to replace libvorbis with tremor (from svn): premitting that I don't want to use the ov_* functions, calling vorbis_synthesis_headerin() on the 3 initial packets works with libvorbis but immediately fails with tremor. At first sight it seems that the function in tremor either receives a leading \n before every header (that

All, I've consolidated our various svn branches of the fixed-point vorbis decoder (known as tremor or tremolo) into a single git repository, hoping that it facilitates review and merging of the various trees. In particular, android has a branch of Robin Watts' Tremolo code (arm-optimized tremor-lowmem) which I don't think anyone on the Xiph side has looked at. I used git-svn to

I thought this might be interesting to the people outside those on the Vorbis development mailing list: http://www.xiph.org/archives/vorbis-dev/200209/0007.html From: rillian (rillian@telus.net) Date: Tue 03 Sep 2002 - 09:24:48 EDT > For those of you not of the commit mailing list, I wanted to point out > that monty has checked the fixed-point 'tremor' vorbis decoder into >

For those of you not of the commit mailing list, I wanted to point out that monty has checked the fixed-point 'tremor' vorbis decoder into xiph.org cvs, under the usual (free) xiph license. This was developed for use in embedded devices, so if you've been waiting for an interger-only (no fpu) implementation, you might want to give it a try. The code is in the 'Tremor' cvs

Hi, I study electricity in the University of Applied Sciences of Western Switzerland and I just began my diploma work: an embedded Internet Radio Receiver. I want to use the Tremor Codec on a ARM7TDMI uc (Samsung S3C4510B). And I need to convert the decoded Vorbis signal in an I2S bus signal (clk, word-select, and data) with a CPLD (Xilinx SPARTAN II) It will be helpfull if someone can explain

Hi, Given CVE-2018-5146, I wanted to update the tremor package we have in Buildroot (an embedded Linux build system), and I noticed an inconsistency between the tremor git and svn repos. We are currently using r19427 from svn, but the fix for CVE-2018-5146 was only added to git, so I wanted to move to that. Comparing the two repos I noticed that r19427 is missing from the git repo. r19427 is:

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, I'm developing squash (shameless plug: http://freshmeat.net/projects/squash/ ), and I've just added FLAC support. I'm going to hold off on OggFLAC support until the high level interface is in place. However, my question concerns compiling libFLAC for the strongarm. First I noticed that I could not use the files compiled by tremor, which I have already working. I suppose

Attached several patches that I have been using to the tremor tree. Please review and apply as you see fit.

Hi, We are working on Oggvorbis encoder porting on embedded platform. Where can we find good test vectors (wav files) for testing OggVorbis encoder? Does anybody have any idea. Parul Embedded Engineer Einfochips Ltd

Hi there. Would some kind soul please refer me to instructions for building an arm-elf-gcc that'll compile the Tremor sources? (In particular, what sources to get and where, and what to build in what order.) I'm developing on Debian Woody i386, but I'll happily take whatever advice you can send my way. I'm no expert in the field of compiler building, but I can't seem to
