similar to: Tremor + upstream libogg

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

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 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));

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 we run a util at work called 'bounds checker' and it came up with this little beauty: void oggpack_readinit(oggpack_buffer *b,unsigned char *buf,int bytes){ memset(b,0,sizeof(oggpack_buffer)); b->buffer=b->ptr=buf; b->storage=bytes; } Stack memory overrun: Copying 20 bytes to opb; Starting offset 0, destination size 4 bytes. This is in RC1 code base. Any ideas?

Hi! This little patch turns bitwise.c's mask[] lookup table into a bit-twiddling macro (which avoids the <<32 case without branching). This spares the size of the 132-byte lookup table (and then a bit more, curiously). While I expected this to generally be faster (because it uses a few more instructions in place of a table lookup), it's actually slightly slower than the LUT, in a

Hopefullly this is once again something trivial I'm missing. I'm still trying to figure out how to pull a part a stream. I get two out the three theora headers I can see in the file (http://v2v.cc/~j/theora_testsuite/320x240.ogg) if I use the buffer in the page struct and nothing usable if I try to use the packet structs. Hopefully this is once again something something trivial I've

Hi All, I am trying to build an Ogg/Vorbis plugin for RealOne Player through the HelixCommunity source. During runtime, however, I saw an access violation. I did some debugging and narrowed it down to the following function in the Vorbis source.. int vorbis_synthesis(vorbis_block *vb,ogg_packet *op){ vorbis_dsp_state *vd=vb->vd; backend_lookup_state *b=vd->backend_state;

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'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 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

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?
