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.
