Abstract: A recording device records an encoded stream in a recording medium. The recording device includes: an obtainer that obtains the encoded stream; a decoder that decodes the encoded stream obtained; and a controller that selectively performs, in accordance with a predetermined setting, first control to record the encoded stream in the recording medium, when the encoded stream obtained is undecodable by the decoder, or second control not to record the encoded stream, when the encoded stream obtained is undecodable by the decoder.
