[Flac] Difficulties to get decoder to work

[Lars von Wedel]

Hi,

I'm developing a plugin for a settop-box application to make use of flac 
files.

However, I have difficulties to get the file-decoder to run in C++. What 
I do in my derived decoder class is basically:

- create an instance of FLAC::Decoder::File, calling also the bsae class 
c'tor
- set_metadata_respond( FLAC__METADATA_TYPE_STREAMINFO ), set_filename()
- process_until_end_of_metadata()
- repeatedly call process_single()

However, none of my callbacks is actually called during the process_* 
calls. Instead, after the call to process metadata, the status of the 
stream decoder is FLAC__STREAM_DECODER_END_OF_STREAM. The same problem 
if I skip the metadata processing call.

Any help or ideas is appreciated.

Regards,
Lars
