The invention discloses a UVD-based HEVC video decoding method which comprises the following steps of: calling a UVD video hard decoding module in an AMD heterogeneous computing platform by means of AMD Media SDK 1.1, analyzing and processing received HEVC video data and inputting the processed HEVC data into a UVD, and continuously acquiring a decoded image from the UVD and pushing the decoded image out. The video decoding method according to the invention improves efficiency in HEVC video decoding and supports real-time decoding for a high-quality HEVC video. Furthermore a universal image data transmission method is used. The UVD-based HEVC video decoding method has higher versatility and higher compatibility. The UVD-based HEVC video decoding method has important practical guiding value for HEVC video decoding in the AMD heterogeneous computing platform.
