ff_apv_entropy_decode_block()

int ff_apv_entropy_decode_block	(	int16_t *restrict	coeff,
		GetBitContext *restrict	gbc,
		APVEntropyState *restrict	state
	)

Entropy decode a single 8x8 block to coefficients.

Outputs nonzero coefficients only to the block row-major order (dezigzag is applied within the function). The output block must have been filled with zeroes before calling this function.
