Detailed Description

Format I/O context.

New fields can be added to the end with minor version bumps. Removal, reordering and changes to existing fields require a major version bump. sizeof(AVFormatContext) must not be used outside libav*, use avformat_alloc_context() to create an AVFormatContext.

struct AVPacketList* AVFormatContext::raw_packet_buffer

Raw packets from the demuxer, prior to parsing and decoding.

This buffer is used for buffering packets until the codec can be identified, as parsing cannot be done without knowing the codec.
