The above embodiments are merely exemplary, and the specific data or network transmission status grading can be determined according to actual situations.
In one or more embodiments, the data packets to be sent and the data packets accumulated by the sending end are sent.
And step S201, adjusting the coding rate of the audio and video data according to the network transmission state grade.
In one or more embodiments, the coding rate of the audio/video data is adjusted to a numerical value corresponding to each network transmission state level according to the network transmission state level.
In one or more embodiments, the coding rate refers to the number of bits transmitted per second, and when the audio/video encoder encodes, the audio/video encoder outputs audio/video stream according to the dynamically changing coding rate, so as to ensure real-time transmission quality.
In one or more embodiments, it is assumed that the encoding code rates of the audio/video data are respectively five values 300, 500, 1000, 1500 and 2000, the above data are merely exemplary, and specific values and units of values are determined according to actual use conditions, which is not limited in the embodiments of the present invention.
In one or more embodiments, assuming that the network transmission state level is excellent, the coding rate of the audio/video data is adjusted to a higher value, and assuming that the network transmission state level is congestion, the coding rate of the audio/video data is adjusted to a lower value.
In one or more embodiments, assuming that the network transmission state level is excellent, the coding rate of the audio/video data is adjusted to 2000; the network transmission state grade is good, and the coding code rate of the audio and video data is adjusted to 1500; if the network transmission state grade is medium, the coding code rate of the audio and video data is adjusted to 1000; the network transmission state grade is poor, and the coding rate of the audio and video data is adjusted to 500; and the network transmission state grade is congestion, and the coding code rate of the audio and video data is adjusted to 300.
And S202, encoding the audio and video data according to the adjusted encoding code rate.
In one or more embodiments, the adjusted coding rate may be used for recording when recording the audio/video data, and the recorded audio/video file may be transcoded according to the coding rate.
In one or more embodiments, assuming that the network transmission state level is excellent when the audio and video data is recorded, the coding rate 2000 is used for video recording, and then before the recorded audio and video data is sent, if the network transmission state level is medium at this time, the recorded audio and video file needs to be transcoded according to the coding rate 1000.
And S203, sending the audio and video data coded according to the coding rate.
In one or more embodiments, the sending end sends the audio and video data coded according to the coding rate to the receiving end.
In one or more embodiments, when the coding rate is higher, more effective data packets are sent to the receiving end in unit time, and when the coding rate is lower, less effective data packets are sent to the receiving end in unit time.
In one or more embodiments, when the coding rate is higher, the network transmission state is better, and more effective data packets can be sent in unit time; when the coding code rate is low, the network transmission state is poor, and the number of effective data packets sent to the receiving end in unit time is small.
In one or more embodiments, in a case where a network transmission state is poor, that is, in a weak network, there may be a case of packet loss, so that while a coding rate is reduced, a data packet needs to be retransmitted, or redundant information is added to the data packet, so that a receiving end can recover the data packet according to the redundant information when the receiving end loses the data packet.
In one or more embodiments, in a case that a network transmission state is poor, packet loss may also occur due to the poor network transmission state, and in order to ensure smoothness of playing audio and video data in the case that the network transmission state is poor, a coding rate needs to be reduced, although a retransmission data packet occupies a bandwidth in the case that the network transmission state is poor, the retransmission data packet still needs to be retransmitted, or redundant information is added to the data packet, so that a receiving end receives the retransmission data packet or recovers the data packet according to the redundant information in the case that the receiving end loses the data packet.
In one or more embodiments, in response to that the RTT is greater than or equal to a first set threshold, a forward error correction coding FEC mechanism is started, redundant information is set, and a receiving end recovers a data packet that is not received through the redundant information without sending a retransmission request to a sending end, thereby reducing occupation of bandwidth in network transmission; or, the sending end itself already starts the FEC mechanism, but the delay is larger than the delay when starting the FEC mechanism, and the FEC mechanism needs to be adjusted to increase the redundant information in the data packet, where the FEC mechanism is usually adopted in the case of low packet loss rate and high delay.
In one or more embodiments, the FEC mechanism includes redundant information in a data packet, specifically, encodes the data packet to generate a supervision code, where the supervision code is used as the redundant information and is transmitted to a receiving end simultaneously with data in the data packet, and when the data in the data packet is lost or erroneous, the receiving end recovers an unreceived data packet according to the redundant information without requesting a transmitting end to retransmit the unreceived data packet.
In one or more embodiments, the redundancy information corresponding to each data packet may also be stored in a data packet before or after the data packet for transmission, which is not limited in the embodiments of the present invention
In one or more embodiments, when the RTT is greater than or equal to a second set threshold and less than a first set threshold, a retransmission mechanism is adjusted to reduce the number of times of retransmission of the data packet; in the case of a weak network, reducing the number of retransmissions may improve the data transmission efficiency.
In one or more embodiments, if the RTT is greater than or equal to the second set threshold and less than the first set threshold, the delay is smaller than the above, so that the FEC mechanism does not need to be started, and only the retransmission mechanism needs to be adjusted.
In one or more embodiments, in response to the packet loss rate being greater than or equal to a third set threshold, a retransmission mechanism is started, or the number of retransmissions of the data packet is increased.
In one or more embodiments, if the packet loss rate is greater than or equal to a third set threshold, the packet loss rate is higher, but the delay is lower, only the retransmission mechanism needs to be started, without starting the FEC mechanism, or the retransmission times of the data packets are increased, so that it is ensured that the receiving end receives the retransmitted data packets, and the flow of playing the audio and video data is ensured.
In one or more embodiments, when the packet loss rate is greater than or equal to a fourth set threshold and less than a fifth set threshold, adjusting the FEC mechanism and increasing redundant information in the data packet; and/or when the packet loss rate is larger than or equal to the fifth set threshold and smaller than a third set threshold, adjusting the FEC mechanism to reduce redundant information in the data packet.
In one or more embodiments, if the packet loss rate is greater than or equal to a fourth set threshold and less than a fifth set threshold, that is, the packet loss rate is less than the above condition, a retransmission mechanism is adopted, and the FEC mechanism may also be adjusted to increase redundant information in the data packet; if the packet loss rate is greater than or equal to the fifth set threshold and less than a third set threshold, a retransmission mechanism is adopted, and the FEC mechanism can be adjusted to reduce redundant information in the data packet.
In one or more embodiments, in response to the packet loss rate being greater than or equal to a sixth set threshold and the RTT being less than a seventh set threshold, increasing the number of retransmissions of the data packet and reducing redundant information in the data packet.
In one or more embodiments, in response to that the packet loss rate is less than an eighth set threshold and the RTT is greater than or equal to a ninth set threshold, the number of retransmissions of the data packet is reduced, and redundant information in the data packet is increased.
In one or more embodiments, the retransmission times of the data packets and the increase and decrease of the redundant information in the data packets are simultaneously determined according to two conditions of the packet loss rate and the RTT.
In one or more embodiments, in the weak network case, the frame rate of the transmitting end may also be reduced.
In one or more embodiments, the coding rate affects the definition of the audio and video, the frame rate affects the smoothness of the audio and video, the greater the coding rate is, the clearer the definition of the audio and video is, the smaller the coding rate is, the more the definition of the audio and video is, the greater the frame rate is, the more the data transmitted in unit time is, the smoother the audio and video is, the smaller the frame rate is, the smaller the data transmitted in unit time is, the situation that the audio and video jumps can occur, the audio and video can be jammed when being played, and the smoothness is poor.
In one or more embodiments, the interaction flow between the sending end and the receiving end is shown in fig. 3, and for convenience of drawing, fig. 3 only shows the interaction flow between one sending end and one receiving end, but the example in fig. 3 is not to be construed as a specific limitation to the embodiments.
