Embodiment 1

[0067] Embodiment 1 is an encoding method in the process of real-time video transmission provided by the embodiment of the present invention, refer to figure 1 As shown, the method includes:

[0068] 101. Obtain the packet loss rate when the network transmits real-time video frames in the current period.

[0069] 102. Determine whether the packet loss rate is greater than the initial threshold, and if the packet loss rate is greater than the initial threshold, perform step 103; if the packet loss rate is less than or equal to the initial threshold, then end.

[0070] 103. Generate prompt information corresponding to the packet loss rate according to a preset condition satisfied by the packet loss rate, where the prompt information is used to indicate an encoding strategy corresponding to the packet loss rate.

[0071] Specifically, according to the numerical relationship between the packet loss rate and at least one preset threshold, determine the threshold range of the packe...

Embodiment 2

[0079] Embodiment 2 is an encoding method in the instant video transmission process provided by the embodiment of the present invention, refer to figure 2 As shown, the method includes:

[0080] 201. Acquire prompt information, where the prompt information is used to indicate an encoding strategy corresponding to a packet loss rate.

[0081] 202. Encode the instant video frame according to the encoding strategy indicated by the prompt information.

[0082] The embodiment of the present invention provides a coding method in the process of instant video transmission, the method is executed by the instant video sending device, because the prompt information received by the instant video sending device is based on the preset packet loss rate. Conditional generation, so that when the packet loss rate is greater than the threshold contained in the preset conditions, the encoding strategy contained in the prompt information corresponding to the packet loss rate can be encoded, ther...

Embodiment 3

[0083] Embodiment 3 is an encoding method in the instant video transmission process provided by the embodiment of the present invention. In the embodiment of the present invention, the execution subject of the method is any one of the instant video receiving device, the instant video sending device, and the server. It may also be other electronic devices, and this embodiment of the present invention does not limit the specific electronic devices. Because layered coding is to encode real-time video frames into frames with different time levels in sequence according to the timing of real-time video frames, and the decoding of each frame can only rely on the previous frames whose time level is not higher than its own time level, so In order to further illustrate the method described in the embodiment of the present invention, the time level is n, where n is a positive integer, and n packet loss rate thresholds are preset, which are respectively: Th(1), Th(2), Th(3), . .., Th(n-1)...

Abstract

The invention discloses a coding method and electronic equipment in the process of instant video transmission, belonging to the field of video, including: obtaining the packet loss rate when the network transmits instant video frames in the current cycle; according to the preset conditions satisfied by the packet loss rate, Generate prompt information corresponding to the packet loss rate, where the prompt information is used to indicate an encoding strategy corresponding to the packet loss rate; and send the prompt information to the instant video sending device. By generating prompt information corresponding to the packet loss rate for indicating the encoding strategy corresponding to the packet loss rate, and sending the prompt information to the instant video sending device, the instant video sending device can be based on the packet loss rate corresponding to the current network. The coding strategy encodes the real-time video. Compared with the traditional coding method, the real-time adjustment of the coding strategy is realized, and the network adaptability of the real-time video is improved.

Description

technical field [0001] The invention relates to the field of video, in particular to a coding method and electronic equipment in the process of instant video transmission. Background technique [0002] In the video communication process of the wireless network, the time domain motion compensation is adopted in the video coding to eliminate the time domain redundancy of the video. Under the traditional real-time video encoding scheme, the real-time video frame after the real-time video frame cannot be decoded due to the packet loss of a certain real-time video frame, which reduces the transmission efficiency of the real-time video, and then reduces the quality of the real-time video. [0003] The existing technology provides a coding method in the process of real-time video transmission. By adopting a layered coding scheme, the video frames are sequentially coded into frames with different time levels according to the time sequence, so that each frame can only depend on the p...
