Abstract

The invention relates to a multimedia data transmission method and device, computer equipment and a storage medium. The method comprises the following steps: under the condition of establishing call connection with a second terminal, sending a first message containing a first video capability set supported by a first terminal to the second terminal; the first video capability set comprising newly added video capability items; the newly added video capability item being constructed by the first terminal according to a mode specified by a control signaling protocol; receiving a second message sent by the second terminal, and analyzing field information in the second message to obtain a second video capability set supported by the second terminal; obtaining an intersection of the second video capability set and the first video capability set to obtain a target video capability set; and determining a target video capability item from the target video capability set, and calling a logic channel corresponding to the target video capability item to transmit multimedia data. By adopting the method, the quality of transmitted video images can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a multimedia data transmission method, device, computer equipment and storage medium. Background technique [0002] With the development of multimedia technology, streaming media streaming not only has a strong demand for traditional applications, but also creates new demands in industries such as video conferencing, distance education, and digital courts. It also has higher requirements for hosts. Users hope that multimedia applications Provide higher-definition, more-channel streaming media streaming capabilities to meet the needs of users in different application scenarios. [0003] However, in the current multimedia data transmission method, because the multimedia communication control protocol cannot cover all the representation methods of audio and video codec capabilities, it is impossible to use the optimal codec capabilities for multimedia data transmission i...
