Ok, here is patch for "current bitrate" displaying in xmms plugin and fix for the artist/performer thing. Attache...

I'm attempting to use the metadata level 2 interface to get at the various interesting bits, which is working fine. But I also need a relevant piece of data, the offset of where the metadata ends, and the audio blocks begin. I'm not finding a clear way to reach that number. Is this exposed anywhere? Thanks. -D -- The revolution will be documented.

Josh, I added the following trivial implementation of the C++ file decoder FLAC::Decoder::File::get_decode_position() to my file_decoder.cpp file... bool File::get_decode_position(FLAC__uint64 *position) const { FLAC__ASSERT(is_valid()); return (bool)::FLAC__file_decoder_get_decode_position(decoder_, position); } I would humbly suggest it be included in future libFLAC++ releases.

Yeah, I was trying to avoid doing that. This is meant for some fast (as opposed to the current pure perl version) header parsing only code, not doing a dec...

Yeah, it's useful, so now there is a FLAC__seekable_stream_decoder_get_decode_position() and FLAC__file_decoder_get_decode_position(). I haven't documented them yet but you can see an example in src/metaflac/operations_shorthand_seektable.c where I use it during seektable creation. > > > In some libFLAC files isn't including of config.h. > > Which ones? > > I hope, i see right, > > bitb...

FLAC__file_decoder_get_decode_position(...) and that will tell you. the decode position is relative to the start of the file even if you have an id3v2 tag in front. native FLAC's metadata system is simple enough that you could also write a custom metadata skipper pretty easily. you just have to parse the lengths out of each m...
