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,

FYI, I have checked in a few interesting things. One is a speedup to the decoder (about 15% improvement in overall decode time). Another is a new interface to FLAC file metadata. If you're curious look at include/FLAC/metadata.h. It is basically a collection of object manipulation routines and iterators that make it pretty easy to add/edit/delete FLAC metadata in files efficiently. The

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

Hi all, Google Security Team member, Michele Spagnuolo, recently found two potential problems in the FLAC code base. They are : CVE-2014-9028 : Heap buffer write overflow CVE-2014-8962 : Heap buffer read overflow For Linux distributions, the specific fixes for these two CVEs are available from Git here:
