Function Documentation

◆ ff_alloc_packet()

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

Check AVPacket size and allocate data.

Encoders supporting FFCodec.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

◆ 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.

◆ pad_last_frame()

static int pad_last_frame	(	AVCodecContext *	s,
		AVFrame *	frame,
		const AVFrame *	src
	)

static

◆ 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
