This framer works directly on the raw ogg_packet as output
|

|
|
Note: the internal setup makes sure, that we initialize
|
||
|
|
the ogg stream to the first found logical bitstream.
|
||
|
|
(For now this should mean: we found vorbis)
|
||
|
|
When the frame goes into the "HAS" state, you have the ogg
|
||
|
|
packet in the in the dest struct from the constructor.
