Function Documentation

ff_packet_list_put()

int ff_packet_list_put	(	PacketList *	list,
		AVPacket *	pkt,
		int(*)(AVPacket *dst, const AVPacket *src)	copy,
		int	flags
	)

Append an AVPacket to the list.

Parameters

list	A PacketList
pkt	The packet being appended. The data described in it will be made reference counted if it isn't already.
copy	A callback to copy the contents of the packet to the list. May be null, in which case the packet's reference will be moved to the list.

Returns

0 on success, negative AVERROR value on failure. On failure, the packet and the list are unchanged.

ff_packet_list_get()

int ff_packet_list_get	(	PacketList *	list,
		AVPacket *	pkt
	)

Remove the oldest AVPacket in the list and return it.

Note

The pkt will be overwritten completely on success. The caller owns the packet and must unref it by itself.

Parameters

head	A pointer to a PacketList struct
pkt	Pointer to an AVPacket struct

Returns

0 on success, and a packet is returned. AVERROR(EAGAIN) if the list was empty.
