[Live-devel] Source, Frames and Parsers

Assuming that your data input class (derived from the "DeviceSource" 
code) delivers discrete audio or video frames (i.e., one frame at a 
time), then you won't need a 'stream parser' at all.  (As the name 
suggests, a 'stream parser' is used only for parsing byte streams.)

No, if data gets truncated like this, then the rest of the data never 
gets delivered.  Therefore, you should try to make sure that data 
doesn't get truncated - by giving the sink object a sufficiently 
large buffer to begin with,
