◆ ff_alloc_packet()

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

Check AVPacket size and allocate data.

Encoders of type FF_CODEC_CB_TYPE_ENCODE 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.
