...mment comment; FLAC::Metadata::SeekTable seek; table[0] = &seek; table[1] = &comment; bool bSuccess = encoder->set_metadata( table, 2 ); The assumption from the (very brief) API doxygen is that it will internally convert from FLAC::Metadata::Prototype pointers to FLAC__StreamMetadata pointers. Looking at the code, it does do the conversion but as a straight cast which is therefore nothing more than an assignment. As the two objects are not equivalent, this is a broken conversion. It results in an array of FLAC_SM pointers that return gibberish when used and produces seg faults,...

Hi, I would like to use the nice C++ wrapper classes for FLAC metadata in a FLAC::Stream::Encoder, but I cannot find an interface to get a "FLAC__StreamMetadata *" from one of those objects. So, as the FLAC::Stream::Encoder.set_metadata() function takes a "FLAC__StreamMetadata **" - so how can I use this, how is this intended to work??? For me all those Metadata classes look nice but useless!? Why is there no conversion, or why does the C...

...m encoder interface. It works fine, but if my application is killed during encoding, the metadata is not being updated since the file isn't closed properly by calling FLAC__stream_encoder_finish(). Thus when opening the file afterwards for playback, it is possible to decode audio data but the FLAC__StreamMetadata.data.stream_info.total_samples field is equals to zero. This is a true problem because it looks like data loss to the user, especially if he/she's been recording for hours... So I'm looking for a way to update the metadata periodically during encoding, before calling FLAC__stream_encoder_...

Yes, it's finally here. See the homepage for details, but here's a summary: - 10-15% decoder speedup - 24-bit input support restored - more robust plugins - new metadata block for Vorbis-style tags - vastly improved metadata editor - fixed bug with pipes and Windows - new libFLAC++, a C++ object wrapper around libFLAC - new metadata editing interface in libFLAC and libFLAC++ - and

Hi, We are using the libFLAC++ library to encode FLAC files with Vorbis comments in them and have had the FLAC 1.1.2 version fail consistently (access violation or segmentation fault) on both Windows and Linux. We tracked this down to the metadata code in the C++ API. The problem is in src/libFLAC++/file_encoder.cpp. There are two problems - firstly, a C-style cast is hiding a bad conversion

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
