Gst.Pad.prototype.chain

function chain(buffer:Gst.Buffer):Gst.FlowReturn {
    // Gjs wrapper for gst_pad_chain()
}

Chain a buffer to pad.

The function returns #GST_FLOW_FLUSHING if the pad was flushing.

If the buffer type is not acceptable for pad (as negotiated with a preceeding GST_EVENT_CAPS event), this function returns #GST_FLOW_NOT_NEGOTIATED.

The function proceeds calling the chain function installed on pad (see gst_pad_set_chain_function()) and the return value of that function is returned to the caller. #GST_FLOW_NOT_SUPPORTED is returned if pad has no chain function.

In all cases, success or failure, the caller loses its reference to buffer after calling this function.
