Abstract
The present invention provides a codec capability negotiation method and terminal thereof. The method includes: storing a negotiation identifier used for indicating whether negotiation is completed in a first terminal and setting the negotiation identifier as negotiation being uncompleted; an encoder of first tell final encoding media data by using a baseline algorithm and then transmitting the encoded media data, and the transmitted data packets carry an encoding algorithm capability set supported by codec of first terminal at the utmost and an indication of negotiation being uncompleted for second terminal to obtain the negotiated encoding algorithm, which is an intersection of encoding algorithm capability sets; when receiving data packets which are transmitted by second terminal and carry the negotiated encoding algorithm and the indication of negotiation having been completed, a decoder of first terminal notifies the negotiated encoding algorithm to encoder and sets the negotiation identifier as negotiation having been completed.
