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? 2013/7/2 Martijn van Beurden <mva...@gmail.com> > On 02-07-13 11:01, Burak Orçun Özkablan wrote: > > I don't use any metadata when encoding and decoding.
