Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
An embodiment of the present invention provides a method for displaying a video frame, and referring to fig. 1, the method includes:
step 101: when a switching instruction for switching a first live broadcast signal source to a second live broadcast signal source is detected, whether a live broadcast video stream of the second live broadcast signal source is cached locally is judged, and the first live broadcast signal source is a live broadcast signal source to which a currently displayed video picture belongs.
It should be noted that the first live broadcast signal source and the second live broadcast signal source may both be network live broadcast signal sources, and certainly may also be traditional live broadcast signal sources, such as live broadcast signal sources accessed through DVBC (Digital Video Broadcasting) interfaces, DTMB (Digital Television terrestrial Multimedia Broadcasting) interfaces, ATV (Analog Television) interfaces, HDMI (High Definition Multimedia interface ), VGA (Video graphics array) interfaces, and the like.
The user is watching the in-process of live broadcast video, can switch the live broadcast signal source through the terminal, thereby watch different live broadcast videos, when the terminal detects to switch the current live broadcast signal source to another live broadcast signal source, can be when the live broadcast video stream of another live broadcast signal source of broadcast, carry out the backstage buffering to the live broadcast video stream of current live broadcast signal source, for example to traditional TV live broadcast signal source, can carry out backstage decoding and buffering to the video stream through video decoder, to the network live broadcast signal source, can carry out backstage download and buffering to the video stream, so, can buffer the video stream of the live broadcast signal source before switching in the terminal.
In addition, the first live broadcast signal source may be switched from the second live broadcast signal source before, or may start playing as soon as the terminal is turned on, or may be switched from a live broadcast signal source other than the second live broadcast signal source, and for the first case, after the second live broadcast signal source is switched to the first live broadcast signal source, the video stream of the second live broadcast signal source may be cached in the terminal, and for the second case, the terminal does not have the cached video stream or may cache the video stream of the other live broadcast signal source other than the second live broadcast signal source.
Further, after detecting a switching instruction for switching the first live broadcast signal source to the second live broadcast signal source, the terminal may cache a live broadcast video stream of the first live broadcast signal source in the following manner, including: when receiving a live video stream of a first direct-broadcasting signal source, caching the live video stream of the first direct-broadcasting signal source, and determining the starting caching time of the live video stream of the first direct-broadcasting signal source; and when the cache space occupied by the cached live video stream of the first live broadcast signal source is larger than a preset threshold value, deleting the live video stream of which the cache time is within a second specified time period from the cached live video stream of the first live broadcast signal source, wherein the second specified time period is a time period which is after the cache starting time and is a second preset time period away from the cache starting time.
The terminal can cache the live video stream of the first live broadcast signal source, so that when the first live broadcast signal source is switched back, at least one frame of video picture can be obtained and displayed from the cached live video stream of the first live broadcast signal source, the video picture is used for playing a transition role in the process of switching the live broadcast signal sources, and the two live broadcast signal sources are smoothly switched. In addition, after the user switches the current live broadcast signal source through the terminal, the current live broadcast signal source may not be switched back, or the current live broadcast signal source may be switched back after a long time, and since the storage space of the terminal is limited, after the live broadcast signal source is switched, all the live broadcast video streams of the first signal source are cached, and then the terminal occupies a considerable storage space of the terminal, so that the terminal can delete the live broadcast video streams of the cached first live broadcast signal source whose caching time is within the second designated time period when the cached caching space occupied by the live broadcast video streams of the first live broadcast signal source is greater than a preset threshold, for example, greater than 40MB (megabyte ), that is, that the live broadcast video streams of the cached first live broadcast signal source whose caching time is within the second designated time period, that is, that the terminal.
Step 102: when the live video stream of the second live broadcast signal source is locally cached, at least one frame of video picture with the caching time within a first appointed time period is obtained from the live video stream of the second live broadcast signal source, and the first appointed time period is a time period which is before the current time and is a first preset time length away from the current time.
The obtaining, by the terminal, at least one frame of video picture whose buffering time is within a first specified time period from the live video stream of the second live broadcast signal source may include: and acquiring a frame of video image of which the buffering time is positioned in a first specified time period and is closest to the current time from the live video stream of the second live broadcast signal source, or acquiring a plurality of frames of video images of which the buffering time is positioned in the first specified time period from the live video stream of the second live broadcast signal source. That is, the terminal may only obtain the last frame of the buffered video image, or may obtain the last frames of the buffered video image.
It should be noted that, because at least one frame of acquired video frame is used for displaying in the process of switching the live broadcast signal source, in order to make the transition of the video frame more natural, the first preset duration should be set to be shorter, that is, the number of the video frames acquired by the terminal should not be too large, so as to avoid the problems that the second live broadcast signal source is accessed, and the acquired video frame is not completely displayed, so that the transition of the video frame is not smooth and the display effect is poor.
In addition, the terminal can acquire at least one frame of video image by performing screenshot operation on the cached video stream, and since the time for capturing one frame of video image is very fast, usually less than 150ms (milliseconds), it does not take a long time for the terminal to acquire at least one frame of video image, and thus the fluency of video image display is not affected.
In a possible implementation manner, when the live video stream of the second live broadcast signal source is not locally cached, the terminal can acquire the video promotion information, display the video promotion information in the switching process of the live broadcast signal source, cancel the display of the video promotion information when the second live broadcast signal source is successfully switched, and display the video picture corresponding to the live video stream of the second live broadcast signal source.
It should be noted that the video promotion information may be a section of video, such as an advertisement, captured from the video stream of the first direct-play signal source when the terminal plays the video stream of the first direct-play signal source, and of course, the video promotion information may also be a video provided by a third party, and in addition, the video promotion information may also be a public service advertisement video stored in the terminal in advance, and the like.
In addition, when the live broadcast video stream of the second live broadcast signal source is not locally cached, the terminal may display the video promotion information, and certainly, in practical application, the terminal may also display a picture stored in advance, or display a stored video picture, for example, the video picture may be obtained by capturing a screenshot of the video stream being played when the live broadcast signal source is switched for the time closest to the current time.
Step 103: and displaying at least one frame of video picture in the switching process of the live broadcast signal source, canceling the display of the at least one frame of video picture when the switching to the second live broadcast signal source is successful, and displaying the video picture corresponding to the live broadcast video stream of the second live broadcast signal source.
The terminal can display the obtained latest frame of video picture in the switching process of the live broadcast signal source on the basis that the terminal obtains the frame of video picture with the caching time being positioned in the first appointed time period and the latest time from the live broadcast video stream of the second live broadcast signal source, and when the switching process is successfully switched to the second live broadcast signal source, the obtained latest frame of video picture is cancelled, and the video picture corresponding to the live broadcast video stream of the second live broadcast signal source is displayed.
On the basis that the terminal acquires the multi-frame video pictures with the caching time within the first specified time period from the live video stream of the second live broadcast signal source, the terminal can display the multi-frame video pictures in sequence according to the caching time of the multi-frame video pictures in the switching process of the live broadcast signal source, cancel the display of the multi-frame video pictures when the switching to the second live broadcast signal source is successful, and display the video pictures corresponding to the live video stream of the second live broadcast signal source.
In the embodiment of the present invention, when a switching instruction for switching the first live broadcast signal source to the second live broadcast signal source is detected, and when the live broadcast video stream of the second live broadcast signal source is locally cached, at least one frame of video picture whose caching time is within a first specified time period may be obtained from the live broadcast video stream of the second live broadcast signal source, that is, at least one frame of video picture adjacent to and before the video picture corresponding to the video stream to be played is obtained.
