Livestream data transmission method, apparatus and system, device and medium

A method for transmitting livestream data, applied to a livestream client and comprising:

• sending a livestreaming request to a livestream server through an established first stream transmission channel of a reliable type;
• receiving data packets sent by the livestream server through the first stream transmission channel and a second stream transmission channel for the livestreaming request, wherein the second stream transmission channel is a stream transmission channel of an unreliable type created by the livestream server;
• and
• determining livestream data to be played matched with the livestreaming request by analyzing the data packets received from the first stream transmission channel and the second stream transmission channel,
• wherein determining the livestream data to be played matched with the livestreaming request by analyzing the data packets received from the first stream transmission channel and the second stream transmission channel comprises:
• receiving data packets from the first stream transmission channel and the second stream transmission channel, and analyzing data content of the received data packets;
• determining, in response to determining that a received data packet does not satisfy a state triggering condition through analysis, that stream transmission is in a blocked state, caching data information related to a livestream data frame in the received data packet to a data cache list, and continuing to execute an analysis operation of a received data packet;
• and
• determining, in response to determining that a received data packet satisfies the state triggering condition through analysis, that stream transmission is currently in a working state, and determining the livestream data to be played matched with the livestreaming request from the data cache list, and
• wherein the livestream data frame is a data frame in the livestream data stream matched with the livestreaming request.

An electronic device, comprising:

• at least one processor;
• and
• a memory configured to store at least one program,
• wherein the at least one program, when executed by the at least one processor, causes the at least one processor to:
• receive a livestreaming request sent by a livestream client, and determine a livestream data stream matched with the livestreaming request, wherein the livestreaming request is transmitted through a first stream transmission channel of a reliable type established by the livestream client;
• create a second stream transmission channel of an unreliable type, and establish an association between the second stream transmission channel and the first stream transmission channel;
• send, through the first stream transmission channel and to the livestream client, response information for the livestreaming request and key information of a livestream data frame in the livestream data stream;
• and
• send, through the second stream transmission channel, the livestream data frame in the livestream data stream to the livestream client, and
• wherein in a process of sending through the second stream transmission channel the livestream data frame in the livestream data stream to the livestream client, the at least one processor is caused to:
• determine, for each livestream data frame in the livestream data stream, an expiration duration of the livestream data frame, and execute, in response to that a retransmission operation for a related data packet of the livestream data frame is present, a discarding processing logic for the livestream data frame according to the expiration duration.
