I assume you mean: https://www.xiph.org/flac/api/group__flac__stream__decoder.html#ga13 which defines the type: typedef FLAC__StreamDecoderWriteStatus (* FLAC__StreamDecoderWriteCallback) (const FLAC__StreamDecoder *decoder,

First, Thank you for your answers. I using the following code to try simply decode a flac file and write the decoded data raw PCM file. The resulting file is just noise and pops, so is the decoded data in a different format than PCM? struct flacData { FILE *inputFile; FILE *outputFile; char *filename; }; FLAC__StreamDecoderReadStatus flac_DecoderReadCallback(const FLAC__StreamDecoder

Hello, I'm looking into storing FLAC audio in Matroska and I have a few questions. 1. Can I use libflac to extract the compressed frames? Or will I need to write up a simple file parser? 2. What is required to decode the frames? From the docs I understand that you need the FRAME and you may need the METADATA_BLOCK. Thanks, Jory Stone jcsston@toughguy.net Matroska, the new,

Hello. I create FLAC file decoding, processing and playing program and have the following question : how to convert FLAC 16 bit file data to 32 bit float buffer for CPU processing? I've already inplemented sound playing and tested it with sine wave - it works without problems; I even made writing into decoding buffer values of sine wave, instead of decoded FLAC file data, and it also works

I'm using seekable_stream_decoder, And., this is my write_callback. I'm not getting the required output. The PCM i get is not the proper music. Am I doing something wrong here?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I am trying to create a FLAC plugin for the K3b CD burning program. To do this I have subclassed the FLAC::Decoder::SeekableStream class. I can obtain the vorbiscomment data using set_metadata_respond, process_until_end_of_metadata and the metadata_callback, however I cannot decode the audio data. It seems to me as though the write_callback

Sorry, I am newbie. Sample codes are from https://github.com/oneman/libflac/tree/master/examples/cpp. I used FLAC__stream_decoder_process_single function but it still gives exception. Maybe I could not control read callback, you're right. I will check it and write result in this thread. Thanks for help. 2013/7/1 Martijn van Beurden <mvanb1 at gmail.com> > I'll top-post this

Thanks Brian. I converted everything to libFLAC and got the same results. Here is some debug output encoder: [34.270050] FLAC encoder set succeeded [34.271183] write_callback, frame: 0, samples: 0 [34.271282] write_callback, frame: 0, samples: 0 [34.271313] write_callback, frame: 0, samples: 0 [34.271351] FLAC encoder initialization succeeded [34.356251] write_callback, frame: 0, samples: 4096

I'm trying to use libflac++ on a live internet audio stream. I don't see anything mentioned in the documentation that suggests this should not be possible, so I hope I'm not chasing down the wrong path (two weeks in). The encoder seems to be working fine and creates data for the write_callback, which I have coded to packetize that data and send it across the network. The question is

I refer to a problem that appeared on the flac list last August that was either solved off-list or abandoned. (http://lists.xiph.org/pipermail/flac/2005-August/000468.html) The problem is with using the C++ encoder classes, particularly the FLAC::Encoder::File:set_metadata function. JC said that the developers version of how to add a simple metadata block looked right, but it did not work for

Hi, I'm working on writing a FLAC encoding plugin for a personal cd ripping project of mine which uses paranoia for the raw audio extraction. My basic setup which follows gets me oddly high pitched audio with lots of noise (although the music IS somewhat recognizable). #include <FLAC/stream_encoder.h> FLAC__StreamEncoder *encoder; FILE *output_file_descriptor; encoder =

Hi all, If I have code that does this: while (FLAC__stream_decoder_process_single (decoder)) /* Do something. */ ; I get an infinite loop. Shouldn't FLAC__stream_decoder_process_single return false if it gets to FLAC__STREAM_DECODER_END_OF_STREAM? If so, here's a patch.

Hi, Which user-authentication plugins should one try first? Too many out there and too little time to try them all fairly. Thanks for your recommendation. cheers! -- Posted via http://www.ruby-forum.com/.

I used the AR modelling written for R (S) on blood pressure and heart rate signals. I used 60 one second samples and a model order of 20. I used the "ar" finction in the "ts" package. Given that blood pressure is measured in mmHg would the spectral density (on the graph displayed be [mmHg]sq/Hz ? And the heart rate is measured in Beats Per Minute (bpm) - so would the

There are several races / deadlocks which I've thought about. Let's see if I can remember them all ... (1) This I experienced: nbd_aio_get_fd deadlocks if there are concurrent synchronous APIs going on. A typical case is where you set up the concurrent writer thread before connecting, and then call a synchronous connect function such as connect_tcp. The synchronous function grabs

Dear All, In the moment i'm using the map and maptools package to read shapefiles and display the maps. I'm looking for the possibility to draw points (randomly positioned or positioned according to a grid) into the polygons instead of filling the polygons with colors. For example: a map (shapefile) with 10 countries, 15 points in the polygon of country A, 20 points in the

Dear All, I am using the scatter.dudi finction in the 'ade4' package to produce correspondence analysis (nice) plots. I do not seem to figure out how to plot the raw coordinates only -- or column coordinates only. I would appreciate any help in doing that. Here is the example I am following -- from the package. data(banque) > banque.acm <- dudi.acm(banque, scann = FALSE, nf =
