Well, I'm quite frankly stumped. I'm writing a program that recurses into directories and reads (among others) FLAC files and should be able to read the vorbis comments ARTIST and TITLE from the file. A while back, I was popen()ing to metaflac, because I didn't want to mess with libFLAC. But now, it's the weekend, so I can mess around with this. Here's the code in question:

Hi, When writing a Rails app, what common tasks can likely result in performance issues? The one I''m aware of is something like: Model.find(:all).each do |elem| # do stuff end Especially when there''s lots of elements in the Model. What other ones are there? Also, does Rails do caching of queries? If I''m in a view and I do: <% if user.admin? %> ... and

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [meta: Thanks, Josh, for clearing that up] Continuing my quest to make everyone think I'm an idiot, could someone explain the following code to me? I.e., what the two for loops are accomplishing, and what, *exactly*, is in s16buffer when it's done. Assume I want to write a .wav file from this decoded flac*. Is it already in approximately

Hi, I've been trying to use the FLAC lib for c++. I need to implement basic encoder function in my application, so i tried to include encoder.h , set everything to the default path, and included stream_encoder.cpp,stream encoder.cpp files in the project. Include is #include "FLAC++/encoder.h" i write something like this FLAC::Encoder::File test; i build, compile goes ok but then

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.

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.

Nevermind, I have discovered the problem(not really a problem). I had called: set_metadata_ignore_all(); because I didnt actually need to use the metadata in my application. But it seems that with this option set, "total_samples" is not set correctly after calling init(). Upon further debugging, I discovered that the test "sample < total_samples" was what is failing in

Hello, I've a problem with seeking using libFLAC++ API. The call to seek_absolute always returns with false, whatever I do.
