Embodiment Construction

[0034] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0035] Various embodiments of the present invention aim at the existing encoding resolution control method, and determine whether the current frame adopts full-resolution encoding or down-sampling encoding according to the frame type of each frame image in the video stream. This encoding resolution control method controls The method is inflexible, which may lead to poor video image quality and v...

Abstract

The invention relates to a coding resolution control method and a terminal and belongs to the computer technical field. The method includes the following steps that: the quantization parameter threshold of a current frame is determined according to a preset rule; the quantization parameter estimation value of the current frame is determined according to the encoding mode of a encoder; and the encoding resolution of the current frame is determined according to the quantization parameter threshold of the current frame, and the quantization parameter estimation value of the current frame. Different quantization parameter thresholds can be set for each frame in a video stream; the coding resolution of the frame is determined according to the quantization parameter threshold and quantization parameter estimation value; and therefore, coding resolutions can be adaptively selected for the frames in the video stream, the coding mode of each frame is more accurate, the quality of video images is improved, the visual effect of the video images is optimized, a user's demand can be better satisfied, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a coding resolution control method and a terminal. Background technique [0002] With the development of mobile Internet, smart terminals, ultra-high-definition display and other technologies, video services are increasingly closely related to people's life and learning. After the video signal is digitized, the data bandwidth is very high, usually above 20MB / s, and it is difficult for the computer to store and process it. Therefore, compression coding technology must be used to reduce the bandwidth to store and process it. Among the working parameters of a video encoder, the resolution has a great influence on the video quality. [0003] In the prior art, it is usually determined according to the frame type of each frame of image in the video stream that the current frame adopts full-resolution encoding or down-sampling encoding. For example, full-resolution encoding ...
