BFU(* QDFP_evtDecoder)(QDFP_ctx *ctx, QDFP_evt *evt, const unsigned int *src, const unsigned int max, BFU bfu)

Callback signature for a QDF event decoder.

Returns:

The updated bit position and current deblocked 32-bit buffer

Parameters:

	ctx	The compressed data decoding context
	evt	The event block to fill in
	src	The data source, i.e. the bit stream
	max	The maximum bit position
	bfu	The current bit position and temporary buffer

int(* QDFP_evtRepacker)(QDFP_evt *evt, QSE_ebfEvt *ebf, int ebf_size)

Callback signature for a QDF event repacker.

Returns:

The size, in bytes, of the repacked event, a negative value indicates an error

Parameters:

	evt	The source event data
	ebf	The destination EBF data block
	ebf_size	The number of bytes availabel in ebf
