The present invention relates to an adaptive real-time transcoding method and a streaming server therefor to improve service quality by minimizing the disconnection of images in an environment, such as a mobile device, through adaptively changing a set value of a transcoding operation on a media streaming service to match a network environment. The adaptive real-time transcoding method of the present invention is a real-time transcoding method for sequentially transmitting a media data segment, divided and transcoded, in a streaming server to the client side over a network, the method comprising the steps of: determining the fill level of a client-side playback buffer; determining, on the basis of the fill level of the playback buffer, the image quality of media data segments that are not transmitted to the client side; and transcoding the non-transmitted media data segments according to the determined image quality.
