similar to: Using CELT on iPod

Hi, I try to work with CELT encoder & decoder in 2 different threads at the same time. So I create/destroy encoder and encode in one thread and create/destroy decoder and decode in other thread. If I didn't protect celt_encoder_create, celt_encode_float and celt_decoder_create, celt_decode_float with CRITICAL_SECTION I get stable error in icwrs32 or ec_byte_write1 (more often) in encoder.

Hi, I'm using CELT encoder/decoder from several threads (but *different* encoder/decoder objects from the different threads) and I have various crash or "abort" (like ec_byte_write_at_end calling "celt_fatal("byte buffer collision");" It there any threading issues to known when using CELT? Thanks Stephane Letz

Hi, In case it is of any help, to compile a static library for the iPhone, I had to add the following 2 lines in plc.c file : #include "arch.h" #include "stack_alloc.h" otherwise "celt_word16..." type are not defined and "VARDECL...." also not. Best Regards St?phane Letz

Hi, Does anyone have experience with running CELT decoder on iPad? thanks, Doron -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipermail/opus/attachments/20110406/6e1af203/attachment-0002.htm

Does Celt encode "silence" buffers (in a stream ) or will it produce "empty" compressed data so that bandwdith could be saved when used on a network? Thanks. St?phane Letz

The code works faster with <4 x float> types, with still works a bit slower than the scalar

Hi, Our DSL emit sub-optimal LLVM IR that we optimize later on (LLVM IR ==> LLVM IR) before dynamically compiling it with the JIT. We would like to simply follow what clang/clang++ does when compiling with -O1/-O2/-O3 options. Our strategy up to now what to look at the opt.cpp code and take part of it in order to implement our optimization code. It appears to be rather difficult to follow

i'm new to linux but am an experienced windows user (former ;-) under windows i used a program called Anapod Explorer to manage my ipod nano. it was great. i looked just like windows explorer and all i had to do was drag and drop from folders to my ipod to transfer music. very simple and easy to use. i've looked a few ipod software programs under linux, but nothing comes close to Anapod. i

I'm having trouble getting my iPod working under Centos 4. I was hoping someone else using their iPod with Centos 4 could shed some light on this. When I attach my iPod via USB, I get these messages: 19:36:44 brahma kernel: usb 1-8: new high speed USB device using address 2 19:36:45 brahma kernel: Initializing USB Mass Storage driver... 19:36:45 brahma kernel: scsi2 : SCSI emulation for USB

Hi, Our DSL LLVM IR emitted code (optimized with -O3 kind of IR ==> IR passes) runs slower when executed with the LLVM 3.3 JIT, compared to what we had with LLVM 3.1. What could be the reason? I tried to play with TargetOptions without any success… Here is the kind of code we use to allocate the JIT: EngineBuilder builder(fResult->fModule);

Hello! I own an Ipod shuffle (512MB) and I am having trouble booting from it using syslinux 3.10pre8 (I have not tested older versions). I guess the Ipod shuffle works just like an ordinary USB key with a FAT32 partition so I have read http://syslinux.zytor.com/usbkey.php. My BIOS identifies it as a hard disk, so I hope I do not have to modify the geometry. Windows assigns the drive letter

how do you apply the ipod patch that maarten made?

Hello all Firstly thanks to everyone involved for creating CELT. It is really very useful :-) One of my targets is current generation Apple iPod with the fixed point decoder (latest version from website, 0.9.1) Based on my simple time-stamp based profiling of my running app it looks like decoding a null buffer for PLC costs a lot more than decoding a normal buffer. For example a standard

Given the (slightly edited) config info below, iPod Touch users are unable to connect, leaving the following message in the log file: dovecot: Jul 23 10:00:40 Info: imap-login: Disconnected (auth failed, 0 attempts): rip=1.2.3.4, lip=5.6.7.8, TLS handshaking: Disconnected Even with maximum logging on, no other error messages seem related to this problem.

Just to let you guys know, I've been listening to FLAC (compression level 2 or lower) tunes on my 3rd generation ipod running ipodlinux (modified uCLinux) for the past few days. No skips or slow-downs whatsoever using MPD to play music. It's pretty cool to be able to use my iPod for the first time in 7 months. (I could've dual-booted the Apple firmware, but nearly all my music is in
