Function Documentation

◆ avpriv_packet_list_put()

int avpriv_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.

◆ avpriv_packet_list_get()

int avpriv_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.
