Detailed Description

Packet structure.

This specifies one packet of compressed data. For video streams, each packet must correspond to a video frame. For audio streams, each packet must be the smallest unit, which can be decoded indepentently and for which a duration is known.

The typical usage of a packet is to memset() oit to zero in the beginning. Then for each packet call gavl_packet_alloc to ensure that enough data is allocated. At the very end call gavl_packet_free to free all memory.
