Problems solved by technology

[0004] In related technologies, when sending video data, if the network condition is not good, a certain data packet is not sent successfully for many times, but the client will always send the data packet, resulting in low video data sending efficiency within the same time, and The video data sent is lagging behind, and the delay is large

Embodiment Construction

[0023] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] With the development of Internet technology, more and more users watch live video. In order to meet the viewing needs of users, how to send video data has become the key. At present, when sending video data, it is mainly based on the TCP protocol and sent through the Internet. Because the TCP protocol mainly functions at the protocol layer, when video data is sent at the application layer, the client can only send it in the order of video encoding, and according to the protocol layer, any data packet cannot be discarded. When the network status is not good, although a certain data packet cannot be sent successfully after being sent many times, the client will continue to send the data packet until the data packet is successfully sent,...

Abstract

The invention discloses a method and device for sending video data, belonging to the technical field of the Internet. The method includes: when the sending time of the video data is reached, acquiring the data packet buffered in the sending queue; according to the data packet buffered in the sending queue, the sending interval of the video data packet and the buffering time limit of the data packet, determining the target sending of the sending data packet this time amount; according to the historical sending time and the target sending amount of the data packets buffered in the sending queue, select the data packets to be sent from the data packets buffered in the sending queue; send the data packets to be sent to the video server. When the sending time of the video data is reached, the present invention determines the target sending amount of the data packets to be sent this time, then selects the data packets to be sent, and sends the data packets to be sent to the video server, thereby ensuring that the sending speed of the video data is stable, Smoothness improves the transmission efficiency of video data within the same time period and reduces the delay.

Description

Technical field [0001] The present invention relates to the field of Internet technology, in particular to a method and device for sending video data. Background technique [0002] With the development of Internet technology, live video on the Internet has attracted more and more users with its novel form and rich content. For example, the host can record a video in the live room and send the recorded video to other users in the live room in real time via the Internet for communication and interaction. [0003] When related technologies send video data, the client first encodes the video to be sent to obtain multiple data packets, and then sends each data packet to the server via the Internet based on TCP (Transmission Control Protocol), and then In the process, the next data packet will be sent only after the previous data packet is successfully sent. If a certain data packet is not successfully sent for many times when the network status is not good, the client will keep sending...
