total_samples of Ogg Flac file
Hi all, I am able to create file containing Flac data encapsulated in an Ogg container. However, when I read the file and its metadata, the total_samples field contains the value zero, even though the file actually does contain samples and the stream does have an end of stream marker. I think something is going wrong when I'm encoding the file. Anybody have any idea of what I have forgotten to do during encoding? Cheers, Erik -- +---------...

better seeking
And here is another one. It allows fast seeking in streams without total_samples information. There is a check for such streams in flac, so flac --skip doesn't work. If the check is removed, it will work with --force-raw-format only, there is an issue with wav and aiff header handling. -- Miroslav Lichvar -------------- next part -------------- --- src/libFLAC/seekable...

Flac and OggFlac
...decode_position Why is that? 2) I have registered a metadata callback function with OggFLAC__seekable_stream_decoder_set_metadata_callback and I'm looking at the metadata struct being passed back. When using regular FLAC the field: metadata->data.stream_info.total_samples is set correctly, but with OggFLAC it seems to always be zero. Why? Can anyone shed any light?

problem with seek_absolute in libFLAC++
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 the seek routine. By removing the call to set_metadata_ignore_all() the problem has disapeared. Sorry this is a rushed explanation,...
