The invention provides a low-delay RTSP video player and a playing method. The player comprises an FFmpeg decoding library, a QT dynamic library and a C/C + + standard library. The C/C + + standard library is used for providing function calling support and logic control support for the FFmpeg decoding library and the QT dynamic library; the FFmpeg decoding library is used for acquiring a plurality of paths of RTSP video streams, unpacking the RTSP video streams to extract video code streams in an H.264 format, and decoding the H.264 video streams to restore YUV image data; and the QT dynamic library is used for converting the YUV image data into RGB image data, and carrying out multi-path simultaneous display on an interface or independently amplifying and displaying a certain path. The playing method is realized through the player. According to the invention, on the basis of the FFmpeg kernel and the QT dynamic library design, the playing control of the H.264 video stream transmitted by the 4-path RTSP is re
