Guests other than domain 0 using the console output have previously been controlled by the VERBOSE #define, but with no designation of which guest''s output was on the console. This patch converts the HVM output buffering to be used by all domains except the hardware domain (dom0): stripping non-printable characters, line buffering the output, and prefixing it with the domain ID. This is

The sound file is played correctly for the first time, then when rewind to the initial position. then copy PCM to buffer, the OpenAL report an error. It seems like the OpenAL doesn't recognize the PCM data. The OpenAL error number : AL_INVALID_VALUE 0xA003 void Buffer::PCMData (ALuint id, ALenum eFormat, ALvoid *data, ALsizei size, ALsizei freq) { // Copy

The main difference is not that much in the bit-stream but in the API. In earlier versions you had to append the terminator manually, whereas I modifed later versions to do it automatically in case programmers forgot (there was no reason not to do so).

Hi. We''re testing the most recent ZFS version from OpenSolaris ported to FreeBSD. Kris (CCed) observed strange situation. In function arc_read() he had a panic on assertion that we try to unlock a lock which is not beeing held: rw_enter(&pbuf->b_hdr->b_datalock, RW_READER); err = arc_read_nolock(pio, spa, bp, done, private, priority, flags, arc_flags, zb);

I write a sample code like speex provide , as follows: SpeeXCodec::SpeeXCodec() { rate = 8000; speex_bits_init(&enbits); speex_bits_init(&debits); enc_state = speex_encoder_init(&speex_nb_mode); dec_state = speex_decoder_init(&speex_nb_mode); // set option for encoder speex_encoder_ctl(enc_state, SPEEX_GET_FRAME_SIZE, &frame_size); speex_encoder_ctl(enc_state,

Hi Tom, Thanks for your reply, I'm having a few difficulty's following you advise. You mention that I should be calling 'speex_encoder_int' & 'speex_decoder_int', I'm having problems finding these functions in the speex header. I am currenlty calling speex_encoder_init & speex_decoder_init in my test code, I have repeated the relevent bits of the example

In short try calling speex_encode_int and speex_decode_int. The calls to speex_encode and speex_decode expects the data to be a floating point values. The data is passed by pointer and the compiler does not do the conversion. This is why you are getting the segfault on decode as the short is 16-bits and a standard float is 32-bits.

Hi, in my application i quite often (not allways) get those two warning: "Invalid mode encountered: corrupted stream?" "Invalid wideband mode encountered: corrupted stream?" The stream is not corrupted but i wish to know what those warning mean to correct my code. My encode and decode routines are those (libspeex 1.1.4): SpeexBits enc_bits, dec_bits; void *enc_state,

hi all, i'm new to speex and i'm stuck on a problem. I have a buffer that holds 5 seconds of audio data, sampled at 16000 hz and quantitized with 16 bits pcm. I only want to encode it with speex and then decode it and write it back in the same buffer. no compiling errors and no errors during runtime, but from the sample of 5 seconds only a short noise is all I get. I hope you have any

Hi everybody, me again. I'm trying to write my own VFW-like dll... It doesn't need to do much. 1.) compress a single frame and give it back to the host application 2.) host applications sends the frame 3.) client application receives frame 4.) client application tells the dll to decompress the data So if I try to do this, something is going wrong... Perhaps someone could have a look at my

Hi All, I'm very new to speex and in fact handling audio at all, it seems I have run in to a problem I seem unable to fix. I'm trying to take audio from a microphone using alsa, then encode it as speex and save to disk. I have been wondering if it has something to do with endian type, but speexenc and speexdec works fine. Currently I have the following setup: Platform:

Hi All, i need your help in determining the problem in the following sample code (taken from speex manual) for fixed point encoding. i tested encoding a 160 sample frame and then decoding it back But The problem is that the decoded frame is totally different from the original frame(see output below).What is the possible reason for this?.thanks for any help #include<stdio.h>

I try test speex in windows.When I try decode a test frames of data encoded by speexenc.exe app.The defrence is the decoded data by speexdec.exe is not same by my app.Here is my test code:what errors I made? Thank you! (My app user speex-1.2beta1 library) int frame_size; int nbBytes=0; int lookahead; int sampleRate=8000; SpeexBits bits; void *dec_state; bEnhance=1; float output[2000]; char

Hi list, I'm trying to figure out how to do the most compatible implementation that will work with as many versions of Speex as possible. I am streaming multi frame Speex blocks over a TCP connection which works fine as long as the version of Speex is the same on both sides. When using a newer Speex (1.1.?) to encode and an older version to decode (1.0.5), it does not work. The encoder

I have now looked at this further and got the idea to hard code the number of frames in the decoder temporarily as a test and voil?, it works! The problem seem to be some incompatibility in the termination handling. After

Hi! I'm totally new to audio programming. I managed to create a VoIP with waveform (PCM). The problem was the really high traffic, so I desided to use speex for compressing the data. I'm recording with mono, 16bit/sample, 8000 samples per second. I tried to add the speex compression, but I always get a crash when I try to decode the data. Here is my encode and decode function: int

I'm not sure if anyone is experienced with this but i'm having very strange issues with implementing speex in my iOS application. I have written a encode and decode function basically exactly like the example files online. To process audio I am using an iOS VoiceProcessingIO Audio Unit which is set at 16bit pcm with 8000 sample rate. After buffering 320 bytes of PCM audio I feed it into
