The invention discloses a video data redundancy control method and device, and aims to carry out refined redundancy protection for the frames of the video data, thus improving the video data transmission performance; in certain embodiment, the method comprises the following steps: obtaining a video code rate and a redundancy level returned by a receiving end, wherein the video code rate and the redundancy level are calculated by the receiving end according to a packet loss ratio; obtaining a data redundancy rate according to the redundancy level; compressing and coding the original video data according to the video code rate, thus obtaining compressed video data; distributing a frame level redundant code rate budget for the compressed video data according to the video code rate and the data redundancy rate; sub-packaging the compressed video data frames according to the frame level redundant code rate budge, and carrying out redundancy coding for the sub-packaged frames of the compressed video data. 本发明公开了种视频
