Enum PacketBufferError 

pub enum PacketBufferError {
    Refcount(Refcount),
    Bounds(Bounds),
    SideDataEntries(SideDataEntries),
    SideDataArray(SideDataArray),
    SideDataPayload(SideDataPayload),
    SideDataBytes(SideDataBytes),
    UnrepresentableFlags(UnrepresentableFlags),
    SideDataAlloc(SideDataAlloc),
}

Why a packet could not be carried across the boundary — its payload, or the side data that comes with it.

Every arm means the bytes are real and this crate could not carry them — never that there were none. “No payload” is Ok(None) from FfmpegBuffer::from_packet, and keeping the two apart is the whole point of the type: a demuxer that reads a refcount failure as an empty marker drops a video packet under memory pressure and carries on as though the file said so. The side-data arms exist for the same reason one tier along — a packet whose side data cannot be carried whole is refused, never delivered with some of it.

Variants

Refcount(Refcount)

av_buffer_ref returned null — out of memory taking a second reference to a payload that is there.

Bounds(Bounds)

The payload does not lie inside the packet’s own buffer.

SideDataEntries(SideDataEntries)

A packet declares more side-data entries than this crate will walk, or a negative count.

SideDataArray(SideDataArray)

A packet declares side-data entries and carries no array to read them from.

SideDataPayload(SideDataPayload)

A side-data entry declares bytes it does not carry.

SideDataBytes(SideDataBytes)

A packet’s side data is larger than this crate will copy.

UnrepresentableFlags(UnrepresentableFlags)

A packet carries flag bits the portable vocabulary cannot hold.

SideDataAlloc(SideDataAlloc)

Out of memory copying a side-data entry.
