CODEC CAPABILITY NEGOTIATION METHOD AND TERMINAL THEREOF

摘要

The present invention discloses a codec capability negotiation method and a terminal thereof. The method includes the following steps: a negotiation identifier, which is used for indicating whether the negotiation is completed or not, is stored in a first terminal and set to negotiation-uncompleted; the encoder of the first terminal encodes the media data with baseline algorithm and then sends the media data, wherein the sent data packets carry an encoding algorithm capability set supported by the codec of the first terminal at the utmost and the indication of negotiation-uncompleted, which enable a second terminal to obtain negotiated encoding algorithm which is the intersection between the encoding algorithm capability sets supported by the first terminal and the second terminal at the utmost; when receiving the data packets which are sent from the second terminal and carry the negotiated encoding algorithm and the indication of the negotiation-completed, the decoder of the first terminal notifies the negotiated encoding algorithm to the encoder and sets the negotiation identifier to negotiation-completed. The present invention realizes the codec capability auto-negotiation, thereby increasing the flexibility of encoding algorithm selection and improving the communication quality.
