In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed description of known functions and known components.
The first embodiment of the present disclosure provides a method for switching media components, when a user uses an operating system of an intelligent mobile device, playing and switching of a plurality of media components are often required, and particularly, in playing and switching of media components in an android system, a phenomenon that a media component to be switched cannot be read and completed in a short time due to a large media component or poor IO performance of the device, or the media component to be switched cannot be timely rendered on a screen due to poor display performance of the device, and finally, a visually perceptible flicker phenomenon occurs due to overlong switching interval time is often caused.
The switching method according to the embodiment of the present disclosure may implement non-perceptual switching between different media components, for example, using an android system, after a user starts playing media through the android system, first loads and displays a current media component, for example, reads a picture and/or a video from a storage device to play, and after the current media component is played, needs to switch to play a next media component, and by adopting the switching method according to the embodiment of the present disclosure, non-perceptual switching between multiple media components may be implemented, as shown in fig. 1, where the switching method specifically includes the following steps:
s101, determining a preloaded media file based on the type of the media component to be switched.
In this step, preloaded media components are determined based on the type of media component to be switched. Specifically, when a current media component is played, in the case that a next media component to be switched, which needs to be played after the current media component is finished, has been determined in advance, a partial file of the media component to be switched needs to be preloaded through, for example, an android system; since the media component to be switched may be a different type of media component, such as a picture type media component, a video type media component, etc., it is necessary to determine the preloaded media file based on the type of the media component to be switched.
Further, in one embodiment, in the step of determining the preloaded media file based on the type of the media component to be switched in the step S101, as shown in fig. 2, the method specifically includes the following steps:
s201, when the media component to be switched is a picture component, the current view size of the current media component is obtained.
In this step, when the media component to be switched is a picture component, the current view size of the current media component is obtained. In order to realize the switching between the adjacent different media components in the playing sequence, it is necessary to ensure that the content displayed by the current media component to be played and the content displayed by the next media component to be played are consistent in view size as far as possible, so that the system does not consume more resources for adjusting the display size of the different media components. For this purpose, the current view size of the current media component needs to be obtained first, where the representation manner of the view size is not limited, and the current view size may be represented by a resolution form, or may be represented by a form of a proportional relationship between the display size of the current playing component and the full-screen size of the display screen.
S202, analyzing the pictures in the picture component according to a preset format based on the current view size to obtain a preloaded media file.
Since the picture component is composed of the picture file, after the current view size of the current media component is obtained in the step S201, in this step, the picture in the picture component is parsed according to the predetermined format based on the current view size, so as to obtain the preloaded media file. That is, after the playing display size of the current media component that is currently played is obtained, the picture file in the media component to be played is parsed according to the playing display size of the current media component, where the parsing process may include, but is not limited to, size adjustment, format adjustment, file compression, and other operations, so that the picture file in the media component to be played is adjusted to the current view size, for example, by compression, and especially, in the case that the size of the picture file is larger than the current view size, size reduction adjustment is implemented, and then a file in a predetermined format is formed, for example, a file in a Bitmap format is formed so as to be preloaded into the system memory of the android system in the later stage.
In another embodiment, for the step of determining the preloaded media file based on the type of the media component to be switched in the step S101, as shown in fig. 3, the method specifically includes the following steps:
S301, when the media component to be switched is a video component, acquiring the current view size of the current media component.
In this step, when the media component to be switched is a video component, the current view size of the current media component is obtained. In order to realize the switching between the adjacent different media components in the playing sequence, it is necessary to ensure that the content displayed by the current media component to be played and the content displayed by the next media component to be played are consistent in view size as far as possible, so that the system does not consume more resources for adjusting the display size of the different media components. For this purpose, the current view size of the current media component needs to be obtained first, where the representation manner of the view size is not limited, and the current view size may be represented by a resolution form, or may be represented by a form of a proportional relationship between the display size of the current playing component and the full-screen size of the display screen.
S302, judging whether the video component has a cover picture or not.
Since the video component is composed of continuous frame images, after the current view size of the current media component is obtained in the above step S302, in this step, it is determined whether the video component has a cover picture. Because the video component needs to load more system resources when rendering on the display screen relative to the picture component, whether the video component has a cover picture or not needs to be judged to preload the cover picture, so that batch loading of the video component is realized, and the resource consumption of a system is further saved.
And S303, when the cover picture is provided, analyzing the cover picture according to a preset format based on the current view size so as to obtain a preloaded media file.
After the current view size of the current media component is obtained in the step S301, and in the case that the video component is judged to have a cover picture in the step S302, in this step, the cover picture in the video component is parsed according to a predetermined format based on the current view size, so as to obtain a preloaded media file. That is, after the playing display size of the current media component that is currently played is obtained, the cover image file in the media component to be played is parsed according to the playing display size of the current media component, where the parsing process may include, but is not limited to, size adjustment, format adjustment, file compression, and other operations, so that the cover image file in the media component to be played is adjusted to the current view size, for example, by compression, and especially, in the case that the size of the cover image file is larger than the current view size, size reduction adjustment is implemented, and then a file in a predetermined format, for example, a file in a Bitmap format is formed so as to be preloaded into the system memory of the android system in a later period.
Further, when the video component does not have the cover picture, analyzing a first frame image of the video component according to a preset format based on the current view size to obtain a preloaded media file as the cover picture.
Specifically, since the video component is composed of continuous frame images, in order to load part of the file of the media component to be switched in the video class in advance, the first frame image of the media component to be switched, that is, the video component, is analyzed, the obtained first frame image is used as a cover image, and is preloaded into a system memory of the android system in a Bitmap format, for example, according to the above manner.
S102, preloading the media file through a system memory.
After the preloaded media file is determined based on the type of the media component to be switched through the above-described step S101, the determined media file is preloaded through, for example, a system memory of an android system in this step. When the media component to be switched is a picture component, the picture type resource in the media component to be switched is preloaded into a system memory to shorten the overall loading time of the media component to be switched of the picture type, so that the switching effect of the play of the media component to be switched of the picture type is improved; when the media component to be switched is a video component, the cover resource in the media component to be switched is preloaded so as to shorten the time for switching to the media component to be switched of the video class, and the switching effect of the media component entering the video class is improved.
And S103, displaying the media component to be switched at a preset time.
After the media file is preloaded through the system memory in step S102, in this step, the media component to be switched is displayed at a predetermined time and the current media component is hidden.
In particular, the predetermined time may be a time when the current media component is played, so as to facilitate the non-aware switching of the media component, and may be other predetermined times.
In this step, when the media component to be switched is a picture component, it is necessary to wait for the playing of the current media component to be completed, and after the playing of the current media component is completed, it is necessary to switch to the media component to be switched, that is, the picture component to be played, firstly, stopping playing the current media component and hiding the current media component; and quickly loading the preloaded picture files from the system memory of the android system, for example, onto a view rendering layer to realize rendering display. At this time, the switching of the media component to be switched is completed, and the preloading of the next component is waited for.
When the media component to be switched is a video component, displaying the media component at a preset moment and hiding the current media component, as shown in fig. 4, including the following steps:
S401, loading the cover picture to a view rendering layer.
S402, video data in the video component is loaded to a video rendering layer, and the video rendering layer is positioned at the lower layer of the view rendering layer.
S403, hiding the cover picture and rendering and displaying the video data after rendering and displaying the cover picture.
Specifically, when the media component to be switched is a video component, waiting for the playing of the current media component is completed; after the current media component is played, the media component to be switched, namely the video component to be played, is required to be switched, and firstly, the playing of the current media component is stopped and the current media component is hidden; rapidly loading the preloaded cover picture file from a system memory of an android system, for example, onto a view rendering layer to realize rendering display; at this time, loading video data in the video component is started by a system, wherein the video data is loaded into a video rendering layer positioned at a layer lower than the view rendering layer loading the cover picture; after rendering and displaying the cover picture, waiting for a first frame in the video data to be rendered on a display screen; when the first frame in the video data is monitored to be rendered on a display screen, hiding the view of the cover picture in the video component, and displaying a video rendering layer positioned on the next layer on the top layer of the display screen; in this way, the video component serving as the media component to be played is switched to be completed, and the next component is waited for preloading. Therefore, the display of the cover picture of the video component is synchronously hidden after the real rendering time when the video data of the video component is loaded on the rendering medium is monitored, so that the smooth transition effect of the play switching of the cover picture of the video component and the video data is achieved, and the play switching effect of the video type media component is improved.
According to the embodiment of the disclosure, the smooth switching of different types of media playing components is realized by preloading and batch rendering of part of files in different media components, so that the non-perception switching of the media playing components is improved, the fluency of media playing can be effectively improved, the switching display effect of media playing is improved, the perception of a user to the switching process is reduced, and the user experience is greatly improved.

Since the picture component is composed of the picture file, after the current view size of the current media component is obtained in the step S201, in this step, the picture in the picture component is parsed according to the predetermined format based on the current view size, so as to obtain the preloaded media file. That is, after the playing display size of the current media component that is currently played is obtained, the picture file in the media component to be played is parsed according to the playing display size of the current media component, where the parsing process may include, but is not limited to, size adjustment, format adjustment, file compression, and other operations, so that the picture file in the media component to be played is adjusted to the current view size, for example, by compression, and especially, in the case that the size of the picture file is larger than the current view size, size reduction adjustment is implemented, and then a file in a predetermined format is formed, for example, a file in a Bitmap format is formed so as to be preloaded into the system memory of the android system in the later stage.
