ff_encode_get_frame()

int ff_encode_get_frame	(	AVCodecContext *	avctx,
		AVFrame *	frame
	)

Called by encoders to get the next frame for encoding.

Parameters

frame

An empty frame to be filled with data.

Returns

0 if a new reference has been successfully written to frame AVERROR(EAGAIN) if no data is currently available AVERROR_EOF if end of stream has been reached, so no more data will be available

ff_get_encode_buffer()

int ff_get_encode_buffer	(	AVCodecContext *	avctx,
		AVPacket *	avpkt,
		int64_t	size,
		int	flags
	)

Get a buffer for a packet.

This is a wrapper around AVCodecContext.get_encode_buffer() and should be used instead calling get_encode_buffer() directly.

ff_alloc_packet()

int ff_alloc_packet	(	AVCodecContext *	avctx,
		AVPacket *	avpkt,
		int64_t	size
	)

Check AVPacket size and allocate data.

Encoders supporting AVCodec.encode2() can use this as a convenience to obtain a big enough buffer for the encoded bitstream.

Parameters

avctx	the AVCodecContext of the encoder
avpkt	The AVPacket: on success, avpkt->data will point to a buffer of size at least size; the packet will not be refcounted. This packet must be initially blank.
size	an upper bound of the size of the packet to encode

Returns

non negative on success, negative error code on failure
