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.

The generic code uses this as a temporary packet to parse packets or for muxing, especially flushing.

For demuxers, it may also be used for other means for short periods that are guaranteed not to overlap with calls to av_read_frame() (or ff_read_packet()) or with each other. It may be used by demuxers as a replacement for stack packets (unless they call one of the aforementioned functions with their own AVFormatContext). Every user has to ensure that this packet is blank after using it.

Used to hold temporary packets for the generic demuxing code.

When muxing, it may be used by muxers to hold packets (even permanent ones).
