So, I'd like some feedback. I only looked briefly, but I had a few questions. How does FLAC__stream_decoder_get_total_samples() work for

I've cross-compiled flac for the armv4l processor (rio receiver), and i'm trying to start up a decode thread : #include <FLAC/stream_decoder.h> .... FLAC__StreamDecoder *flac = NULL; flac = FLAC__stream_decoder_new(); if (flac == NULL) { printf("[DECODE] Unable to initalize flac object\n");

...ck. The flac file I'm using is a 16/44.1 wav file i encoded(and decoded to verify it worked). Any thoughts? Alas, although I can generate a core file, I havn't been able to get get gdb to recognize it. Is there any way to turn on verbose debugging messages from flac?

...plication - FLAC__stream_decoder_set_metadata_respond_all - FLAC__stream_decoder_set_metadata_ignore - FLAC__stream_decoder_set_metadata_ignore_all That means the metadata filters can now be changed after initialization, which wasn't possible before. Additionally, two structs were changed. To FLAC__StreamDecoderReadStatus, FLAC__STREAM_DECODER_READ_STATUS_END_OF_LINK was added. To FLAC__StreamDecoderState, FLAC__STREAM_DECODER_END_OF_LINK was added. These two additions break the ABI compatibility. Op zo 1 sep 2024 om 23:55 schreef Timothy B.

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,

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

Yes, I have tried plain wav data with file and stream functions of decoder and encoder. They work succesfully. You're right about FLAC can't find the first block in stream, because I didn't add any metadata in stream. The documentation of FLAC says that metadata callback function is optional for stream function of decoder, so I didn't need adding metadata. Actually, I am sure
