Enum MediaBuffer 

pub enum MediaBuffer {
    Packet(Arc<Packet>),
    Video(Arc<UnboundObjectPoolRef<Video>>),
    Audio(Arc<Audio>),
    Eos,
}

The unit of data that flows between elements.

Compressed and uncompressed data are kept as distinct variants (rather than a single opaque Buffer type like GStreamer) because ffmpeg-next already gives us strongly-typed Packet/Frame types — collapsing them into one type would just mean unwrapping again downstream.

Payloads are Arc-wrapped so MediaBuffer is cheaply Clone — duplicating a buffer (e.g. crate::elements::Tee fanning packets out to a decode branch and a remux branch) is a refcount bump, never a copy of the encoded/decoded data.

Video specifically wraps an UnboundObjectPoolRef, not a plain ffmpeg::frame::Video — that’s what lets whichever element produced it (see crate::pool::UnboundObjectPool, owned as that element’s own struct field) get the underlying buffer back automatically once every Arc clone downstream has been dropped, instead of it just being freed.

Variants

Packet(Arc<Packet>)

Video(Arc<UnboundObjectPoolRef<Video>>)

Audio(Arc<Audio>)

Eos

End of stream marker. Elements that hold resources (encoders with delayed frames, muxers, …) should flush when they see this.

Implementations

impl MediaBuffer

pub fn is_eos(&self) -> bool

pub fn kind(&self) -> &'static str

Stable, human-readable variant name for diagnostics emitted when elements are wired to an incompatible media type.

Trait Implementations

impl Clone for MediaBuffer

fn clone(&self) -> MediaBuffer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
