[flac-dev] About Decode Streaming

[Burak Orçun Özkablan]

Yes, I have tried plain wav data with file and stream functions of decoder
and encoder. They work succesfully.
You're right about FLAC can't find the first block in stream, because I
didn't add any metadata in stream. The documentation of FLAC says that
metadata callback function is optional for stream function of decoder, so I
didn't need adding metadata.

Actually, I am sure about network data transferring is good, there is no
problem, i have tested so much and observed all data has transmitted at
every time. I suspend that sync problem occurs from network latency.
Do you have any idea about this? If read callback may sleep or process more
than excepted time, does sync lost?
