枚举 AVIODataMarkerType 

#[repr(i32)]
pub enum AVIODataMarkerType {
    AVIO_DATA_MARKER_HEADER = 0,
    AVIO_DATA_MARKER_SYNC_POINT = 1,
    AVIO_DATA_MARKER_BOUNDARY_POINT = 2,
    AVIO_DATA_MARKER_UNKNOWN = 3,
    AVIO_DATA_MARKER_TRAILER = 4,
    AVIO_DATA_MARKER_FLUSH_POINT = 5,
}

Different data types that can be returned via the AVIO write_data_type callback.

Variants

AVIO_DATA_MARKER_HEADER = 0

Header data; this needs to be present for the stream to be decodeable.

AVIO_DATA_MARKER_SYNC_POINT = 1

A point in the output bytestream where a decoder can start decoding (i.e. a keyframe). A demuxer/decoder given the data flagged with AVIO_DATA_MARKER_HEADER, followed by any AVIO_DATA_MARKER_SYNC_POINT, should give decodeable results.

AVIO_DATA_MARKER_BOUNDARY_POINT = 2

A point in the output bytestream where a demuxer can start parsing (for non self synchronizing bytestream formats). That is, any non-keyframe packet start point.

AVIO_DATA_MARKER_UNKNOWN = 3

This is any, unlabelled data. It can either be a muxer not marking any positions at all, it can be an actual boundary/sync point that the muxer chooses not to mark, or a later part of a packet/fragment that is cut into multiple write callbacks due to limited IO buffer size.

AVIO_DATA_MARKER_TRAILER = 4

Trailer data, which doesn’t contain actual content, but only for finalizing the output file.

AVIO_DATA_MARKER_FLUSH_POINT = 5

A point in the output bytestream where the underlying AVIOContext might flush the buffer depending on latency or buffering requirements. Typically means the end of a packet.
