A replay method of live videos implemented by a replay server, the method comprising: receiving a replay request sent by a platform control server, a storage path in a storage server for the specified video file being included in the replay request, wherein the specified video file is obtained after a live streaming server records live streaming source data of a live video uploaded by a first anchor client, and the specified video file is uploaded to the storage server by the live streaming server; retrieving, from the storage server, the specified video file to which the replay request is directed; and converting the specified video file to a video stream, and transmitting the video stream to the live streaming server to allow the live streaming server to transmit the video stream to a second user client, wherein the replay request is directed to at least two specified video files in the storage server, wherein each of the at least two specified video files has a corresponding playing sequence number, and the method further includes: transmitting video streams that respectively correspond to the at least two specified video files to the live streaming server based on playing sequence numbers, to allow the live streaming server to transmit the corresponding video streams to the second user client based on the playing sequence numbers, wherein the replay request includes replay cutoff parameters, and the replay cutoff parameters are configured to provide a defined number of times of replay or a defined duration of replay of the video stream transmitted to the second user client; and the method further includes: transmitting the replay cutoff parameters to the live streaming server, so that the live streaming server stops transmitting the video stream to the second user client when a number of times of replay of the video stream reaches the defined number of times of replay or a duration of replay reaches the defined duration of replay. receiving a replay request sent by a platform control server, a storage path in a storage server for the specified video file being included in the replay request, wherein the specified video file is obtained after a live streaming server records live streaming source data of a live video uploaded by a first anchor client, and the specified video file is uploaded to the storage server by the live streaming server; retrieving, from the storage server, the specified video file to which the replay request is directed; and converting the specified video file to a video stream, and transmitting the video stream to the live streaming server to allow the live streaming server to transmit the video stream to a second user client, wherein the replay request is directed to at least two specified video files in the storage server, wherein each of the at least two specified video files has a corresponding playing sequence number, and the method further includes: transmitting video streams that respectively correspond to the at least two specified video files to the live streaming server based on playing sequence numbers, to allow the live streaming server to transmit the corresponding video streams to the second user client based on the playing sequence numbers, wherein the replay request includes replay cutoff parameters, and the replay cutoff parameters are configured to provide a defined number of times of replay or a defined duration of replay of the video stream transmitted to the second user client; and the method further includes: transmitting the replay cutoff parameters to the live streaming server, so that the live streaming server stops transmitting the video stream to the second user client when a number of times of replay of the video stream reaches the defined number of times of replay or a duration of replay reaches the defined duration of replay. transmitting video streams that respectively correspond to the at least two specified video files to the live streaming server based on playing sequence numbers, to allow the live streaming server to transmit the corresponding video streams to the second user client based on the playing sequence numbers, wherein the replay request includes replay cutoff parameters, and the replay cutoff parameters are configured to provide a defined number of times of replay or a defined duration of replay of the video stream transmitted to the second user client; and the method further includes: transmitting the replay cutoff parameters to the live streaming server, so that the live streaming server stops transmitting the video stream to the second user client when a number of times of replay of the video stream reaches the defined number of times of replay or a duration of replay reaches the defined duration of replay.
