A data processing method and apparatus, and an electronic device, a system and a storage medium are provided. The method is applicable to a main thread in a Web client and includes: obtaining audio and video data of a target video from a server decapsulating the obtained audio and video data to obtain first audio and video data; sending the first audio and video data to a target sub-thread in the Web client, so that the target sub-thread decodes the first audio and video data to obtain second audio and video data and sends the second audio and video data to the main thread; receiving the second audio and video data sent by the target sub-thread; and rendering video data in the second audio and video data by using a rendering module of a browser of the Web client, and taking the rendered video data and audio data in the second audio and video data as to-be-played data for the target video. The technical solution according to the embodiment of the present application allows a Web client to play audio and video data without browser plug-ins.

Data processing method and apparatus, electronic device, system, and storage medium

A method and apparatus for voice transmission and reception by a browser and a voice intercom system are provided. The method for voice transmission by a browser includes: collecting first voice data through a built-in audio collection interface of the browser (S); obtaining a first voice sampling parameter that can be utilized by a target device (S) to process voice data; sampling the first voice data based on the first voice sampling parameter to obtain target voice data (S); and transmitting the target voice data to the target device (S). The method enables a browser to have a function of voice intercom without using a plug-in.

Method and apparatus for sending and receiving voice of browser, and voice intercom system

Provided is a system for cross-network data storage. A gateway is used for connecting a first network and a second network; a client sends an address acquisition instruction and a first IP address and port number of a coder to the gateway, acquires a second IP address and port number of the coder from the gateway, and sends a stream acquisition instruction and a first IP address and port number of a PCNVR to the gateway; the coder receives the address acquisition instruction and sends the second IP address and port of the coder to the gateway; and the PCNVR parses the stream acquisition instruction to acquire the second IP address and port number of the coder, acquires a code stream from the coder via the second network, and stores same. Also provided is a method for cross-network data storage. The method and system of the present invention can be adopted to reduce network bandwidth pressure of an external network, and improve the stability of data storage.

System and method for cross-network data storage

The present invention provides a method and system for video surveillance with a single channel of video and multiple channels of audio. The method comprises: a device end allocating a fixed initial SSRC value for each channel of audio; a client end and the device end establishing an RTSP interaction mode; the client end requesting, from the device end, a single channel of video and multiple channels of audio, the device end randomly generating, for each channel of audio, a corresponding modified SSRC value, and sending the same to the client end; the device end capturing the single channel of video and the multiple channels of audio and sending an RTP packet of the single channel of video to the client end, and after modifying the initial SSRC value in the RTP packet of each channel of audio to the corresponding modified SSRC value, sending the RTP packet of each channel of audio including the modified SSRC value to the client end; the client end distinguishing individual channels of audio according to the modified SSRC values in the RTP packets of the multiple channels of audio, and playing the video and/or the audio of a corresponding channel according to a user's demand. The present invention can implement audio-video capturing of multiple channels of audio and a single channel of video, and enable a user to select freely and play video and/or audio of a corresponding channel.
