Problems solved by technology

[0004] In the existing no-reference video quality assessment method based on frame type parameters, it is necessary to detect the video frame type first, and there is no complete and effective method for detecting frame type in the prior art
[0005] In addition, the existing frame size detection methods are only applicable to frames without packet loss, and there is no effective solution for the size detection of frames with packet loss

Abstract

An embodiment of the invention provides a video streaming frame type detection and frame size detection method and device. The video streaming frame type detection method comprises the following steps of obtaining the size of a current video frame, wherein the current video frame is arranged behind a first video frame of a video streaming; obtaining a change feature value of the current video frame according to the size of the current video frame and the adjacent previous video frame of the current video frame; obtaining an I frame threshold value of the current video frame according to the video frame rate and the position of the current video frame; judging whether the previous video frame is an I frame or not according to change feature values of the current video frame and the previous video frame, the I frame threshold value of the current video frame, the current video frame and the previous video frame and the size of previous two video frames. According to the video streaming frame type detection method which is complete and efficient, only one former video frame is taken into consideration when the frame type of the previous video frame is detected and influences of the video frame rate are fully taken into consideration.

Description

technical field [0001] Embodiments of the present invention relate to multimedia technology, and in particular to a method and device for detecting frame size of a video stream. Background technique [0002] In the context of the rapid development of network media, services such as video on demand, Internet TV, and videophone have become the main services of broadband networks and wireless networks, making operators need to monitor the quality of transmitted video services and take corresponding measures to adjust them in time To ensure user experience requirements for media services. Network video quality assessment is an essential technology in network video applications. [0003] According to the degree of need for the original reference video, video objective quality assessment methods can generally be divided into three categories: full-reference, partial-reference, and no-reference video objective quality assessment. Due to the limitation of channel bandwidth, the vi...
