[Flac-dev] seek problem

[Peter Kunath]

Hi Flac developers!

I'm using the seekable_stream_decoder API of libFLAC 1.03
and I'm stuck with a mysterious problem:
my FLAC plugin works nicely as long as the seek_absolute()
function is never used, but as soon as I seek around in a
sample (ie. call seek_absolute() with an offset != 0), I cannot
detect the end of a file anymore. decoder_get_state() never
returns FLAC__SEEKABLE_STREAM_DECODER_END_OF_STREAM in this
case.
First I thought that this might be a problem of my eofCallback,
but the last file offset where this callback is called is
0x013788f7, but the flac file is 0x01382598 bytes long (ie.
there's no reason for my callback to return true). When I don't
seek, the last offset where my eof routine is called is 0x0137b936
and decoder_get_state() properly returns END_OF_STREAM. Any ideas
whats wrong?
BTW - why does stream_decoder_finish() call the function
seekable_stream_decoder_set_defaults_() which clears all
callback pointers? In flac 1.02, I had to set the callback
pointers only once, but in 1.03 I have to set them after every
decoder_init()/decoder_finish() pair. Is this intentional or
a bug in 1.03?
BTW2 - I still think that it would be better if 
seekable_stream_decoder_seek_absolute() wouldn't call
the write callback.
And finally, a function like
seekable_stream_decoder_process_frames(decoder, numframes)
would be useful, IMHO.
