First, the noun terms to which one or more embodiments of the present application relate are explained.
X5 kernel: and a depth-optimized browser rendering engine.
Immersive video playing: and the video is full of the whole screen.
Most of mobile phones adopt X5 kernels, the video played normally is mostly in the proportion of 16:9, but the current mobile phone proportion is not only 16:9 alone, but also 16:10 and other screen proportions, and when the video needs to be played on the full screen of the special-shaped screen mobile phone, the best viewing experience can be achieved by adapting in various ways.
The traditional video immersive playing scheme has two types, the first type is that the clipping mode of the video is set to be object through css: full screen adaptation is achieved by fill, full screen playing can be achieved, but if a video needs to be played in an H5 page embedded in communication software, the communication software can automatically print a full screen character to the upper right corner of the video, a kernel of the communication software can be called to play the video in a full screen mode after clicking, a player of the communication software can be popped up, control over the video is lost at this time, display elements on the upper layer of the video become invisible, controllability is poor, a second scheme is a same-layer playing mode of the kernel of the communication software X5, the effect of full screen playing can be achieved while the full screen character at the upper right corner of the video is removed only by adding two attributes of X5-video-player 5 and X5-video-player-fullscreen to a video tag, but the full screen mode also has a disadvantage that a full screen mode of the kernel of X5 causes a zooming process, the watching experience of a user is influenced, and meanwhile, the top right label of the current page becomes a full screen quitting button instead of a sharing function carried by communication software, and the requirement of most scenes is not met.
