Embodiment Construction

[0020] Please refer to figure 1 A schematic diagram provided by an embodiment is shown. The implementation environment includes a client 10 , a server 20 , a conversion device 30 , and a client 40 .

[0021] Client 10 can be mobile phone, panel computer, video camera etc., client 10 is installed with the client 10 application program software that supports RTMP agreement, and client 10 can set audio frequency collection module and video collection module itself simultaneously, also can audio frequency The acquisition module and the video acquisition module are connected to the client 10.

[0022] Through the audio collection module and the video collection module on the client 10, the audio data and video data collected by the application program on the client 10 will generate media stream data through the RTMP protocol of the network application layer, and the media stream data will be transmitted in real time through the Internet to the software server 20 that supports the...

Abstract

The invention discloses a method, a device and a system for converting an RTMP protocol into an NDI protocol, and the method comprises the steps: obtaining media stream data from a server supporting the RTMP protocol; analyzing and extracting audio and video frames from the media stream data; decoding the audio and video frames to obtain original audio and video data; and converting the original audio and video data into target media stream data through an instruction, wherein the target media stream data is suitable for NDI protocol transmission. The method disclosed by the invention comprises the following steps of: importing media frequency stream data transmitted by adopting an RTMP (Real Time Message Protocol) on a network into a target media stream data production workflow of a localarea network adopting an NDI (Network Data Interchange) protocol; the video source range in the local audio and video production workflow is expanded, and the conversion cost from an RTMP protocol platform to an NDI protocol platform is reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a conversion method from RTMP protocol to NDI protocol, a conversion device and a conversion system. Background technique [0002] The RTMP protocol is the abbreviation of Real Time Message Protocol (Real Time Information Transmission Protocol), which is an application layer protocol proposed by Adobe to solve the multiplexing (Multiplexing) and packetizing (packetizing) of multimedia data transmission streams. )The problem. With the rise of live video and other fields, the RTMP protocol is widely used. [0003] NDI is the abbreviation of Network Device Interface (Network Device Interface), which is an open IP (Internet Protocol) network interface protocol launched by NewTek. NDI can transmit and receive multiple broadcast-quality signals in real time through the IP network, and has the characteristics of low delay, accurate frame video, mutual identification and commun...
