The invention discloses a self-adaptive code rate calculation method based on live streaming media, and relates to a target buffer size decision mode based on network feature classification. Accordingto the invention, more accurate decision making is carried out according to the buffer area and the throughput at the same time, faster and slower broadcast adjustment is carried out according to thesize of the current buffer area, smoother live broadcast experience is brought to users, and QoE optimization is realized in various network environments. Compared with the prior art, the method hasthe advantages that the streaming media live broadcast fast broadcast and slow broadcast opportunities are dynamically judged according to the current network condition and the cache size; smoother live broadcast watching experience is brought to the user; the current network bandwidth can be predicted more accurately, and strong guarantee is provided for adaptive code rate decision; according tothe current network conditio
