According to one embodiment, information processing apparatus which decodes compressed and encoded video stream by software, selectively generates one of intra and inter prediction image on the basis of encoding mode of decoding object from video stream and decoded images thereof, generates a residual error decoded image on the basis of a quantization parameter of decoding object from video stream, generates decoded image by adding intra and inter prediction image selectively generated, and residual error decoded image, applies deblocking filter process for reducing block distortion onto decoded image, extracts at least one of information on a quantization parameter and information on encoding mode of decoding object from video stream, determines whether or not filter process is skipped on the basis of extracted information thereof, and selectively skips filter process on the basis of a result of determination, and selectively switches determination and processing of skip to be valid or invalid.
