similar to: Tremor + upstream Ogg library

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 all I found that in the revision 10730 of the libogg2 library it is impossible to do bitpacking. this is due to the implementation of the (at least) two functions oggpack_writeinit() and oggpack_readinit(). they both take an (oggpack_buffer *) as an argument and immediately erase all it's contents: void oggpack_readinit(oggpack_buffer *b,ogg_reference *r){ memset(b,0,sizeof(*b));

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

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, 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 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 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

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 probably also want to do something like Index:

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 porting the vorbis encoder to Symbian platform,(to support ogg recording) everything works fine for the emulator(PC), but then on the Hardware whenever I am trying to record it gives KErrOverFlow(buffer OverFlow). We get this error from the driver when the latency of the codec is too high. The main reason is that the hardware does not have the floatpoint unit and the

Can anybody point me at any resources that would explain how to optimize mdct_backward for a cpu with a fused multiply-accumute unit? >From what I understand from responses to my older postings, Tremor's mdct_backward could be rewritten to take advantage of a muladd. My target machine can do either two-wide 32x32 + Accum(64) -> Accum(64) integer muladd or eight-wide 16x16 + Accum(32)

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?

Hi, Debian Project News drew my attention to an RFH http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=698378 for a crash in libvorbisidec (tremor) on ARM systems. I have been in contact with Daniel Kahn Gillmor proposing to try to help solve this crash on armel. Unfortunately Daniel hasn't been able to reproduce it recently. Can anyone shed any light on this crash or on how to reproduce

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
