Constructor & Destructor Documentation

SPDIFEncoder()

SPDIFEncoder::SPDIFEncoder	(	const QString &	muxer,
		AVCodecID	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

GetData()

int SPDIFEncoder::GetData	(	unsigned char *	buffer,
		size_t &	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.

SetMaxHDRate()

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
