Hi! I'm new to this list. I work at a game development company, and we are considering Ogg Vorbis for the audio in a cell phone game. Does anyone here have any figures or educated guesses on how much CPU power the decoding requires? I guess Tremor is the decoder to use, as the CPU doesn't have a floating point unit, but will it be possible to use it for playing background music in a

Hello, First off, please don't ask development questions directly from a single developer. I tend to answer emails only a few times a month. You will get much faster help by asking on IRC (#vorbis on freenode) or on the vorbis mailing list (vorbis at xiph.org or vorbis-dev at xiph.org). I am cc:inf vorbis-dev at xiph.org; please continue discussion there. > Initially i was not able to

Hello Joost, I would like to say since you seem to understand what Vorbis is since you are in the appropriate list that you should not refer to it as "OGG". First, because Ogg is not Vorbis -- it's a container. Second, because Ogg is not an acronym. Vorbis decoding help is what you are looking for. With that said, let's see if I can help you.

Hi All, I am trying to program the 'Tremor' decoder onto an array of Processors. I am using four Processors. I did this experiment: I split the while(!eof){} in the main() in to four tasks using if(!eof) statements. In this modification, each if() decodes one packet of data at-a-time, sequentially. Then, I ran the code on a single Processor and the decoding was successful. The

Hi all The inline asm in Revision 10571: /trunk/Tremor file asm_arm.h seems to be in x86 inline assembly format. is there a code which is compatible with ARM/Thumb C/C++ Compiler, RVCT2.2,along with libvorbis-1.1.2 release. regards anand -------------- next part -------------- An HTML attachment was scrubbed...

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

Hello, All. I am making an Ogg Vorbis decoder based on Tremor. The Vorbisfile library provides a high-level API which enables us to seek in the file, but it needs to declare a pointer to OggVorbis_File structure. Because I am supposed not to use file, so I can't use the ov_pcm_seek() or ov_raw_seek() functions to seek in the file. For decoding an Ogg Vorbis file, I first put it in

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 am trying to load vorbis tool on to my arm board EDB9302 , till now i have cross compiled libao, libogg, libvorbis, flac, speex and vorbis tool. when i run the command line arm-linux-ogg123 with some sample ogg format file on my arm board it gave *"Could not load default driver and no driver specified in config file : Exiting"* , please help me to over come this error.

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

http://www.vorbis.com/faq.psp#money ...mentions Tremor as being licensed for money.

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

Hi, I'm trying to decode a (Ogg/Vorbis) web radio stream (FIFO) with Tremor but always get error -132 (...not a Vorbis stream). When writing and reading the stream as a file everything works fine (also other ordinary Ogg files work well). When writing the stream into a FIFO (created with mkfifo) the ov_open (and all its relatives) fail. There is only one 1024 Byte block read - and

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

Thanks, for all that help from this list. I need only the decoder to implement. I will compile the tremor projekt next week and post my success or fail. If it works fine I will sell the boards on ebay, if this is ok? It would then be a player modul for ogg vorbis and wave with midi input.

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

Hello, I'm interested in getting vorbis up and running on the PlayStation 2. I'm an official developer, not a ps2 linux developer, but the issues should be roughly the same. I've gotten the code to compile but our setup (intentionally) doesn't have libm so I'm seeing references to several double-precision math functions. Some of the issues I'm seeing: - As reported on
