Member Function Documentation

◆ decode() [1/2]

VideoFrame av::VideoDecoderContext::decode	(	const Packet &	packet,
		OptionalErrorCode	ec = `throws()`,
		bool	autoAllocateFrame = `true`
	)

decodeVideo - decode video packet

Parameters

	packet	packet to decode
[in,out]	ec	this represents the error status on exit, if this is pre-initialized to av::throws the function will throw on error instead
	autoAllocateFrame	it true - output will be allocated at the ffmpeg internal, otherwise it will be allocated before decode proc call.

Returns: encoded video frame, if error: exception thrown or error code returns, in both cases output undefined.

◆ decode() [2/2]

VideoFrame av::VideoDecoderContext::decode	(	const Packet &	packet,
		size_t	offset,
		size_t &	decodedBytes,
		OptionalErrorCode	ec = `throws()`,
		bool	autoAllocateFrame = `true`
	)

decodeVideo - decode video packet with additional parameters

Parameters

[in]	packet	packet to decode
[in]	offset	data offset in packet
[out]	decodedBytes	amount of decoded bytes
[in,out]	ec	this represents the error status on exit, if this is pre-initialized to av::throws the function will throw on error instead
	autoAllocateFrame	it true - output will be allocated at the ffmpeg internal, otherwise it will be allocated before decode proc call.

Returns: encoded video frame, if error: exception thrown or error code returns, in both cases output undefined.
