similar to: FLAC__stream_decoder_seek_absolute calling write callback

Hello, The API documentation [1] `FLAC__stream_decoder_seek_absolute` says: "Flush the input and seek to an absolute sample. Decoding will resume at the given sample. Note that because of this, the next write callback may contain a partial block." I expected that subsequent `process_single` calls would return data starting exactly from the sample I've seeked to. To my surprise

-----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

I'll have to see the whole class definition to tell what's wrong; nothing below looks wrong. the unit tests (see src/test_libFLAC++/) have some examples and the write callbacks do get called.

Hi, Here's a patch to add support for streaming HTTP transport to the xmms plugin. Most of the code (in particular, http.c) is taken from the xmms mpg123 input plugin. You'll need to make a three-line change to the xmms mpg123 input plugin to get streaming to work. The mpeg plugin currently handles all http urls itself unless they end in an ogg or real audio extension (which means flac

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

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

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? FLAC__StreamDecoderWriteStatus AFLACStreamPlayer::StreamWriteCb ( const FLAC__SeekableStreamDecoder *decoder, const FLAC__Frame *frame, const FLAC__int32 * const buffer[], void *client_data) { int Channels,

I can't be totally sure what 'short' is on your platform, but if it's (probably) 16-bits, it looks like you're treating the samples in buffer[] as packed 16 bit numbers. but all samples in buffer[] are 32-bit signed integers in host order, regardless of the bits-per-sample of the frame. so to get them down to shorts (assuming they'll fit), do like: FLAC__int32 *

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

Hi, Not sure if this should be in the dev or users list, but here goes. I am using the FLAC seekable stream decoder in my MACH3 laser games emulation in MAME (www.boldtower.com/mach3). The game has a soundtrack (originally on a laser disk) which I have flac encoded and play back in the game. I did the implementation under Linux which works fine, the callbacks are easy to set up and I've

Hi Chris, Have you tried the Standard C libflac option? Not that I have anything against the C++ flavor, but I've only ever worked with the C API, to keep things simple. Sorry for the brief response, but I wanted to reply quickly.

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

For instance the write_callback thing: client_data ? can it be a pointer to just about anything? For instance a pointer to a two-dimensional array? Are those FLAC-WAV and WAV-FLAC examples the only examples available? What would be the best approach to read a FLAC file to an array of some kind? Passing a pointer to the array as ?client_data?? I'd like to use a two-dimensional array, but

Hi again, I can not solve problem. I want to mention my source code, so you may answer easily. This is decoder init stream function. *FLAC__stream_decoder_init_stream(m_decoder, decoderReadCallback, NULL, NULL, NULL, NULL, decoderWriteCallback, NULL, decoderErrorCallback, input_pile_array);* * * Then, callbacks * * /// \brief read callback function of decoder FLAC__StreamDecoderReadStatus
