Embodiment 1

[0045] refer to figure 1 , a flow chart of a video playing method provided by an embodiment of the present invention is given.

[0046] Step 101, forming a panoramic image buffer according to the panoramic video data, and filling the panoramic image buffer into a buffer queue.

[0047] Among them, the panoramic video is obtained by the application program, including the 360-degree panoramic video, which is obtained by capturing the image information of the entire scene with a professional camera or using a modeling software to render the picture, using the software to stitch the pictures, and playing it with a special player panoramic image. It is used for virtual reality browsing, simulating the two-dimensional floor plan into a real three-dimensional space, and presenting it to the user.

[0048] In this embodiment, the application in the VR field is taken as an example. In order to determine that the played video is a panoramic video, a panoramic flag flag may be set in ...

Embodiment 2

[0058] On the basis of the foregoing embodiments, this embodiment further discusses a video playing method.

[0059] refer to figure 2 , a flow chart of another video playback method provided by an embodiment of the present invention is given:

[0060] Step 201, forming a panoramic image buffer according to the panoramic video data, and filling the panoramic image buffer into a buffer queue.

[0061] Specifically, the application program dequeues buffer1 from the BufferQueue to carry image information, fills the panoramic video data obtained by the application program into the buffer1 to form GraphicBuffer1, and then queues the GraphicBuffer1 to the BufferQueue to complete the transfer of the panoramic video data to the system import.

[0062] Step 202, obtain the panorama image buffer from the buffer queue for image management.

[0063] Specifically, after filling the panoramic video data into the BufferQueue, SurfaceFlinger obtains the GraphicBuffer1 from the BufferQueue...

Embodiment 3

[0075] On the basis of the above embodiments, this embodiment also provides a video playing device, which is applied to a virtual reality terminal.

[0076] refer to Figure 7 A structural block diagram of a video playback device provided by an embodiment of the present invention is given, which may specifically include the following modules:

[0077] The image import module 701 is configured to form a panoramic image buffer according to the panoramic video data, and fill the panoramic image buffer into a buffer queue, where the panoramic image buffer includes a panoramic mark.

[0078] The image management module 702 is configured to obtain a panoramic image buffer from the buffer queue for image management, so as to obtain a pre-processed image buffer.

[0079] The extraction module 703 is configured to extract the pre-processed image buffer through the system to generate the scene image buffer according to the motion sensing data collected by the motion sensor.

[0080]Th...

Abstract

The embodiment of the invention provides a video playing method and device. The video playing method comprises the steps of forming panoramic image buffer according to panoramic video data, filling the panoramic image buffer to a buffer queue, and then acquiring the panoramic image buffer from the buffer queue so as to obtain preprocessed image buffer. Extraction is performed on the preprocessed image buffer through a system according to motion sensing data collected by a motion sensor so as to generate scene image buffer, so that the system is enabled to perform synthesis and display after carrying out extraction on the panoramic image buffer according to the latest sensing data, the image delay time caused by motion of a user can be substantially shortened, and thus use feelings of the user are improved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to a video playing method and device. Background technique [0002] With the rapid development of VR (Virtual Reality, virtual reality) technology in recent years, users of VR products are also increasing. For users of VR products, the strongest experience is the immersion in the playing content. [0003] In the prior art, users generally suffer from dizziness during the use of VR products, lose the sense of immersion, and seriously affect the user experience. This kind of dizziness is mainly caused by the long delay time of the picture, where the picture delay refers to the time interval between the user (head) movement starts and the user sees the picture after the movement is completely displayed on the terminal device. When the time interval exceeds 20ms, the user will perceive the picture delay. If the picture delay is too long, the human body sensing tec...
