SPDIFEncoder::SPDIFEncoder	(	QString	muxer,
		int	codec_id
	)

SPDIFEncoder constructor Args: QString muxer : name of the muxer.

Use "spdif" for IEC 958 or IEC 61937 encapsulation (AC3, DTS, E-AC3, TrueHD, DTS-HD-MA) Use "adts" for ADTS encpsulation (AAC) AVCodecContext *ctx : CodecContext to be encaspulated

void SPDIFEncoder::WriteFrame	(	unsigned char *	data,
		int	size
	)

Encode data through created muxer unsigned char data: pointer to data to encode int size: size of data to encode.

int SPDIFEncoder::GetData	(	unsigned char *	buffer,
		int &	dest_size
	)

Retrieve encoded data and copy it in the provided buffer.

Return -1 if there is no data to retrieve. On return, dest_size will contain the length of the data copied Upon completion, the internal encoder buffer is emptied.

bool SPDIFEncoder::SetMaxHDRate ( int rate )

Set the maximum HD rate.

If playing DTS-HD content, setting a HD rate of 0 will only use the DTS-Core and the HD stream be stripped out before encoding Input: rate = maximum HD rate in Hz
