similar to: 'const data' in celt_decode()

Is this a common warning? The decoder doesn't return an error on it, but I see it a lot in my test application on windows. It is non existent on my linux box. I haven't tried mingw yet. please note that I'm using visual studio 2008 w/the vcproj that Bjoern Rasmussen made for 0.5.2 (w/some file references removed) at the moment and it is giving a lot of C4554 warnings

Hi I noticed a crash issue when I passed the following values: celt_mode_create(96000, 258, &e); CELTMode->mdct.kfft[0] is not initialized after calling?clt_mdct_init() and when?celt_mode_destroy() is called it tries to dereference this value in kiss_fft_free(). -- Bjoern Here's the callstack: !kiss_fft_free(const kiss_fft_state * cfg=0x00000000) ?Line 650 + 0x3 bytes

Hi I minor issue I noticed when I passed an invalid 'channels' parameter to celt_encoder_create() is that celt_encoder_init() doesn't free the CELTEncoder ('st' parameter) when 'if (channels < 0 || channels > 2)' evaluates to true. Seems celt_encoder_init() should do like this instead: CELTEncoder *celt_encoder_init(CELTEncoder *st, const CELTMode *mode, int

I am working on a project that transports audio in realtime from a linux box to a windows box throuh libcelt. The windows client program is written in C# and C++ and I therefore need the celt library in its most recent version (0.7) to be able to compile in Visual Studio 2008. In order to do this I, as I understand it, need a .vcproj file for the project. Are there any plans on making such a

Hi I'm trying to stream a Theora encoded video over the internet using UDP. Since Theora typically produce an encoded frame of 10 KBytes in my scenario I need to split up this frame in smaller chunk which are then sent to clients. This, however, makes my application very vulnerable to packet loss, so I'm wondering if there is some way to make the Theora encoder produce many small frames

HiI'm trying to run CELT on Win32 but I'm running into some corrupted stack errors when using alloca(). When get_required_bits32() (in file cwrs.c:308) is called from get_required_bits() (in file cwrs.c:328) the 'K' parameter is 1 which means that the uint32 which is allocated on the stack only has 3 bytes instead of 4. This results in a corrupted stack in the following call to

Hello, I'm building packages for Slackware and I've just tried to upgrade Slackware 13.37's CELT package to version 0.11.3, which apparently was released last year, but I've omitted it because it was not announced on the site. Anyway, now that I try build with the following configuration in my SlackBuild script: CFLAGS=$SLKCFLAGS -O2 \ CXXFLAGS=$SLKCFLAGS -O2 \

Hi Is there a way to estimate the number of bytes per second from the information passed in the th_info-struct to the Theora encoder's th_encode_alloc()? I'm trying to be able to give users a rough estimate of the file size needed to encode with the setting provided to th_info-struct (frame width/height, fps_numerator/fps_denominator, target_bitrate and quality). -- Bjoern

Hello The st->zeta pointer isn't freed in the speex_preprocess_state_destroy() function of the preprocess.c file (alloced in line 167). It's in Speex 1.1.4 by the way. I'm trying to make the denoiser work with my application and has got reasonable noise reduction after applying the denoiser. I, however, haven't been able to find any information of what the purpose of

Hello Greg If money isn't a problem Intel has an optimized compiler for eVC and XScale processors http://www.intel.com/software/products/compilers/techtopics/PCA_Optimization_WP.pdf If you have any luck getting the eVC compiler closer to realtime I'd really like to know. I'm still far from realtime when using Speex 1.1.3 on a HP iPAQ (Intel pxa255). Best regards Bjoern D.

Hello there I'm having trouble decoding speex frames when using 32KHz audio and quality setting 4. If I encode three frames and then decode the three frames then the speex_bits_remaining() still reports that there are bits remaining. All other band modes and qualities reports that the buffer is emptied. Here's an example that shows 4 bits remaing in the buffer after the frames have

Hi all, I am the developer of the llcon software (llcon.sf.net) which is a software making it possible for musicians to play in real-time over the internet. Up to now I have used ADPCM or no audio coding. Gregory Maxwell was pointing me to the great CELT project. Using CELT has the advantage to be able to use higher sample rates, getting lower code rate and better error concealment. I have

Hi I'm using syslinux 5.01 and is installing our bootloader using "extlinux --install /boot". In the extlinux.conf I've specified that the kontron_wdt.c32 program should boot another label once it has been executed but it never calls the second label. Here's my extlinux.conf: default wdt timeout 5 prompt 1 label linuxfoo kernel /vmlinuz append root=/dev/sda2 #.... more

Hi Ady I tried removing Syslinux TIMEOUT and typing 'wdt' but the 'linuxfoo' label is still not called. I have to enter it manually and it will start. The "timeout=120" parameter is for the kontron_wdt.c32 watchdog. So the system will reset after 120 seconds if the watchdog hasn't been serviced. We're rebuilding the syslinux source code since we're cross

Hi,I have been trying some different sample rate and bitrate combinations to get a feel for how CELT behaves,too, like Andrew Lentvorski. But I want to use VBR option.I want to ask a question about VBR in CELT codec.Can we use VBR option in CELT ??? "byte_per_packet" variable in code means constant bit rate, does not it ?In this code : bytes_per_packet is constant.len =

I don't think a compiler is going to be enough. I tried perl scripting the output of a linux gcc cross-compiler to convert into something the assembler under eVC would consume. It errors on all the MAC type of instructions. I looked at www.arm.com (I never knew there could be so many arms) It does not look like the ARM720 has the MAC instructions. It also lists 75Mhz and 100Mhz as possible

Hello All, I extended the libNE10 optimizations for float towards mdct_backwards/opus_ifft. I am able to get about 14.26% improvement for Decode use case now on my Beaglebone Black. Please see [1] for measurements. Questions 1. Since this patch needs to go in after Encode [2] patch) should I submit this as patch series? 2. Since Jonathan Lennox posted intrinsics cleanup [3] patch, should
