// This setups a decoder per block, but seems Vorbis' uses first frame as setup so it

// returns samples (576 vs 1024), making num_samples count in each block being off + causing
|
|
// gaps. So they must be using a single encoder + setting decode_to_discard per block
|
|
// to ge the thing working.
|
|
//
|
|
// However since blocks are probably also used for seeking, maybe they aren't resetting
|
|
// the decoder when seeking? or they force first frame to be 1024?
|

//
|
|
// In case of Vorvis, when setting skip samples seems repeated data from last block is
|
|
// exactly last 0x800 bytes of that channel.
