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 consist of b...

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...

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 incorporate Vorbis decoder within my application. In my app I just want to decode the encoded files, and play them OutLoud. But I don't know where to begin. I'd appreciate if anyone can provid...

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...

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 import t...

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 me the exact form of the output signal given by the Tremor Codec. I suppose that t...

...nning 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 supported for audio portable player? 6) Floor0 is termed to be obsolete, Does this mean non of the commercially available encoder supports Floor0? Please clarify the above points if possible. Thanks in advance. Best R...

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...

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 module. As usual, nigh...

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 find a combination of bin...

hi, could someone please apply these to Tremor svn? 0001-update_symbols.patch there are 3 public symbols in the headers, which are missing in the linker script and thus marked as private again. This causes issues for e.g. gstreamer (https://bugzilla.gnome.org/show_bug.cgi?id=616194). 0002-pkgconfig.patch this adds a pkg config file You proba...

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.

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 r1942...

I checked out the lowmem-branch of Tremor from CVS but some files like synthesis.c seem to be missing on that branch. What am I doing wrong?
