Those skilled in the art will appreciate that the display terminal configuration shown in fig. 1 is not intended to be limiting of display terminals and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
The invention provides a video playing method, which comprises the following steps:
step S10, obtaining video fragments required by video playing, wherein the video fragments comprise panoramic video fragments and planar video fragments;
in this embodiment, videos are played on a segment basis, and the video segments are divided into panoramic video segments and planar video segments according to the fixity of the viewing angle or the difference of the viewing mode. It can be understood that a complete video may be composed of multiple video segments, and in the prior art, a video may be correspondingly segmented into multiple panoramic video segments or multiple flat video segments according to types, in this embodiment, in a video production process, a video is segmented into a video segment set composed of flat video segments and panoramic video segments according to actual needs, such as narration scenarios and switching of display angles, and at this time, the total number of video segments in a video may be equal to a pre-planned total number of segments, or may be greater than the total number of segments but less than 2 times the total number of segments, that is, in some scenarios, there may be a flat video segment and a panoramic video segment at the same time.
Step S20, selecting video segments according to the playing sequence of the video to play the video, and detecting whether the video frame of the currently selected video segment has a view angle switching identifier; if yes, go to step S30;
it should be noted that, the video segments are sequentially arranged during the production, so that the sequential playing of the video can be ensured, and whether the view switching identifier exists in the video frame of the segment corresponding to the currently playing episode can be detected during the playing process. If the current video playing is not the next sub-slice playing, the switching of the visual angle does not occur, otherwise, if the current video playing is the next sub-slice playing, the switching of the visual angle occurs.
The view switching identifier is a view switching label (Tag), and the view switching identifier may be set in a previous video production process, may be set in a part of the video segment, and corresponds to a certain video frame in the video segment, for example, may correspond to a certain frame in the last frames of the currently played video segment, specifically, may be the last frame, or may be the last frame. It should be further noted that the view switching identifier may be stored together with the video clip, or may only have a corresponding relationship, for example, stored in an index file or a video playlist required for video playing. The video switch flag may also be marked with a difference of the front and rear view switch videos, such as whether the encoding format is changed, whether the resolution is changed, and the like. The video switching view may be switched from planar to panoramic, e.g., 360 degrees panoramic, 180 degrees or other display view, or from panoramic to planar.
Step S30, when the currently selected video segment is a panoramic video segment or a flat video segment and the playing of the video segment is completed, the flat video segment or the panoramic video segment is correspondingly selected for playing.
If the current fragment of the video frame corresponding to the video switching identifier is detected to be the panoramic video fragment, the video fragment to be switched is the planar video fragment; and if the video is the planar video fragment, the video fragment to be switched is the panoramic video fragment. When the switch identifier corresponds to a video frame other than the last frame, preferably in several frames relatively behind, the transition process of the play switch based on the panoramic video and the flat video is gradual or transitional, for example, the display screen is first changed from deep to shallow, and then changed from shallow to deep, or other transition effects. And when the video frame corresponding to the switching identifier is in the last frame, the switching has no gradual change process.
According to the embodiment, mutual switching between the panoramic video fragments and the planar video fragments can be realized according to the visual angle switching identification, so that planar video playing is inserted between two segments of panoramic videos needing to be switched in visual angles on the premise that the playing visual angle is adjustable through a video fusion playing technology, and playing switching is not abrupt.
In addition, in other embodiments, the number of the video segments may be that one video has all panoramic video segments and all planar video segments, or another type of segment is used for alternate playing when the user has a switching requirement and the current segment playing is completed, and the implementation process may refer to the foregoing embodiments and is not described herein in any more detail.
Further, based on the foregoing one embodiment, referring to fig. 3, in another embodiment of the video playing method of the present invention, the step S10 includes:
step S11, acquiring a video play list;
and step S12, obtaining the video fragments required by video playing through the video playing list.
The process of acquiring the video playlist may be that the display terminal initiates a video playing request to the server, where the video playing request includes an identifier of a video to be requested to be played, the server feeds back a corresponding video playlist for playing the video according to the video playing request, and the display terminal may parse and start playing after receiving the video playlist. When the server and the display terminal are integrated, namely the display terminal has a video production function, the request and the distribution list can be directly transmitted in a local mode, and when the server is in communication connection with the display terminal, the request and the distribution list can be transmitted in a network mode.
The video playlist may be a custom extension of an existing playlist, such as hls (HTTP Live streaming) or MPEG-DASH, where MPEG-DASH (dynamic adaptive streaming over HTTP, ISO/IEC 23009-1) is a vendor-independent international standard approved by MPEG and ISO and is a HTTP-based streaming media transmission technology using TCP transmission protocol, thereby ensuring compatible support of video playback for products or players. Of course, a new standard may be redefined, which may be a new video playlist or a new file format, for example, a file resource package is formed by encapsulating the video clips and other required resources/information, where the file resource package is similar to the video playlist, and exists as a video playing resource in a new format, and when the video clips are acquired, the corresponding video streams may be read from the media files of the video playing resource similar to the MP4 format for acquisition.
The content included in the video playlist may be set according to actual needs, and since the video clips need to be acquired through the video playlist, the video playlist may store the required video clips, that is, the video clips required for video playing are acquired from the video playlist, or may store locators required for acquiring the video clips, for example, a URL (Uniform Resource Locator) of the video clip required for video playing is acquired from the video playlist, and the video clips are acquired according to the URL. Other information may also be included, such as at least one of a view switch identification, scene resources, and video transition animation resources.
The embodiment obtains the video fragments through the video playlist, provides a specific scheme for how to obtain the video fragments, and takes the video playlist as a channel, so that other required information for video playing can be included at the same time, the method is convenient and fast, and the interaction times are reduced.
Further, in yet another embodiment, special effects may be added during video playing, which may be setting scene resources, such as cinema scenes, during plane playing, and setting switching animations/effects during video switching. In addition, as a special playing mode, panoramic video playing also needs to be provided with a model for back projecting video.
Specifically, when the corresponding selected next video segment is a panoramic video segment, a panoramic projection model may be obtained according to the video playlist before the video segment is played, so that the selected panoramic video segment is played under the loaded panoramic projection model after the planar video segment is played. The method includes the steps that a model is obtained according to a video play list, a scene resource package URL can be actually set in the play list, the scene resource package generally comprises a dynamically loaded model or a picture resource, when a play end of a display terminal is switched to a first frame or a few previous frames of a new plane video play visual angle, the scene resource can be loaded at a rendering end of the display terminal at the same time, and the method is correspondingly suitable for loading of a relevant model for panoramic video back projection in the panoramic video, such as a spherical model or a polyhedral model.
Similarly, if the video playing is switched to the video playing in the display terminal by using the flat video segment, the virtual scene can be defined to play, and the scene resource packet URL corresponding to the video playing list has the scene resource packet address. If the scene resource package address is not provided, a default scene or a custom scene of the playing end can be used. In concrete implementation, when it is determined that the video segment to be played next is the flat video segment, it may be determined that there is no scene resource corresponding to the flat video segment in the video playlist, and if there is a scene resource corresponding to the flat video segment, the scene resource is acquired, otherwise, the default or custom scene of the playing end is selected for playing in combination. After the scene resources are acquired, when the playing end of the display terminal is switched to the first frame or the first frames of the panoramic video playing new view angle, the acquired scene resources can be loaded at the rendering end of the display terminal to play the selected planar video segments in the corresponding scene.
The embodiment simulates the actual watching scene effect by adding the scene special effect during the playing of the plane video, and is more simulation. In addition, when the panoramic video is played, the panoramic video is played under the loaded model, so that the playing effect of panoramic back projection is ensured.
Further, in this embodiment, when switching animation/effect is set during video switching, that is, when the switching animation/effect is interspersed during view switching, a transition animation resource URL may be set in the video playlist or the transition animation resource may be directly stored in the video playlist, so that before the view switching is performed, the video transition animation resource may be obtained according to the video playlist. It can be understood that the transition dynamic effect resource is similar to a scene resource, and is mainly used for being loaded by a rendering section of a display terminal player in different types of video switching processes, so that scene transition is realized, and the transition process is more natural. Corresponding to the video switching process added with the transition dynamic effect, the player can sequentially play the currently selected video fragments, the video dynamic effect corresponding to the video transition dynamic effect resource and the corresponding selected video fragments. If the currently selected panoramic video is, sequentially playing the currently selected panoramic video fragment, the video dynamic effect corresponding to the video transitional dynamic effect resource and the correspondingly selected planar video fragment. And if the currently selected planar video fragment is the planar video fragment, sequentially playing the currently selected planar video fragment, the video dynamic effect corresponding to the video transition dynamic effect resource and the correspondingly selected panoramic video fragment.
It should be noted that the sequential playing may be to play only one video resource at a time, or to play the last frames of the currently selected video segment and the transitional animation effect in an overlapping manner when the video transitional animation/effect is used for transition, and/or to play the first frames of the correspondingly selected video segment and the transitional animation effect in an overlapping manner. Through the interpenetration of the transition dynamic effect resources, the transition is ensured to be more natural.
In addition, transition dynamic effect resources and scene resources can exist in the whole video playing process, and when the scene resources are loaded, the transition dynamic effect can be closed, and the scene resources are displayed; when the switching is started, the switching dynamic effect loading is completed, the scene resources can be closed, and the video switching process is started.
Optionally, in other embodiments, the switching between the flat video segment and the panoramic video segment may further involve a difference in resolution or video format, and further may be determined by other information in the view switching identifier, and if both are consistent, the new video segment is directly switched to be played; when any one of the video slices is different, the player of the display terminal needs to reinitialize the decoder to input the video stream of the new visual angle to be switched and played to the decoder for decoding until the new video slice is refreshed to the last frame, and the specific implementation process is to judge whether the coding formats or resolutions of the currently selected video slice and the correspondingly selected planar video slice or panoramic video slice are different according to the visual angle switching identifier; if so, initializing a decoder and decoding the correspondingly selected planar video segment or panoramic video segment through the decoder so as to play the correspondingly decoded planar video segment or panoramic video segment after the playing of the currently selected video segment is finished, thereby ensuring the normal playing of the video.
Furthermore, the invention also proposes a computer-readable storage medium, on which a computer program is stored. The computer-readable storage medium may be the Memory 20 in the terminal in fig. 1, and may also be at least one of a ROM (Read-Only Memory)/RAM (Random Access Memory), a magnetic disk, and an optical disk, and the computer-readable storage medium includes instructions for enabling a terminal device (which may be a helmet, a smart television, a mobile phone, a computer, a server, or a network device) having a processor to execute the method according to the embodiments of the present invention.
