Problems solved by technology

The video encoder uses the encoding parameters adjusted in this way to encode the video and output the video code stream. When the network status changes, the video quality output by the video encoder is poor, with large blur and distortion, and the fluency is not high. , prone to problems such as Caton

Embodiment approach

[0080] Such as image 3 As shown, an optional implementation manner of step 207 or the above-mentioned step 103 includes:

[0081] 2071. Calculate the code rate adjustment step size and the code rate adjustment direction according to the network characteristic parameters used in this encoding parameter adjustment;

[0082] 2072. According to the code rate adjustment step size and the code rate adjustment direction, adjust the code rate currently used by the video encoder to obtain a matching code rate.

[0083] 2073. Obtain the target encoding parameters required for this encoding parameter adjustment according to the matching code rate.

[0084] In an optional embodiment, the network characteristic parameters fed back by the video receiving end include parameters such as expected code rate, packet loss rate, and data packet loopback delay. Correspondingly, the network characteristic parameters used for this encoding parameter adjustment include: smoothing Expected code rate...

Abstract

A method and apparatus for adjusting encoding parameters are provided in the present application. The method includes: receiving network performance parameters fed back by a video receiving end; smoothing at least one network performance parameter received prior to the present to obtain the network performance parameter used during this encoding parameters adjustment; according to the network performance parameter used during this encoding parameters adjustment, obtaining the target encoding parameter required during this encoding parameters adjustment; and adjusting the encoding parameter which is used by a video encoder as the target encoding parameter. The present application can improve the video quality and fluency of video encoding output.

Description

【Technical field】 [0001] The present application relates to the field of communication technologies, and in particular to a coding parameter adjustment method and device. 【Background technique】 [0002] In recent years, the development of the network has promoted the change and innovation of communication means, and people can communicate through the network. The popularization of broadband network has changed the quality and form of traditional network communication, so that communication is no longer limited to language and text, and communication and collaboration can be carried out through video, so the video communication system appeared. [0003] The processing process of the existing video communication system is as follows: the video sending end collects the original video information through the video acquisition equipment such as the camera, and after preprocessing, it is sent to the video encoder for encoding to generate a video code stream, which is then packaged...
