MediaPlayer unit, creates mediaPlayer object for passing through surface composer client, and the video source file of the needs broadcasting that mediaPlayer object is corresponding is set;
Setting unit, is set to the surfaceTexture of Video Layer for surfaceTexture corresponding to local surface;
Broadcast unit, for displaying video source file.
Further, described Surface creating unit is creating after local surface, and directly figure layer priority corresponding to local surface is set to the highest.
Further, described mediaPlayer unit, before creating mediaPlayer object, can judge whether mediaPlayer service is ready.
Further, described CPU also comprises:
Judging unit, for judging whether the video playback time is less than the time of android backstage loading service, if be not less than, after waiting until that background service has started, discharge relevant resource and exit video playback process, otherwise, before video playback process exits on screen the last frame picture of display video always.
A kind of playback equipment, described playback equipment comprises above-described video opening device, described playback equipment comprises smart mobile phone, Web TV, Set Top Box, panel computer.
The invention has the beneficial effects as follows:
The present invention adopts a kind of video starting-up method, device and playback equipment based on Android system, in the time of start, change the mode of the simple picture of tradition broadcasting, start shooting in the mode of displaying video, thereby for user provides more amount of information, and the form of expression is abundanter.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the invention will be further described.
Fig. 1 is the method for the invention flow chart;
Fig. 2 is apparatus structure composition schematic diagram of the present invention.
Embodiment
Shown in Fig. 1, the invention provides a kind of video starting-up method based on Android system, comprising:
For the equipment with Android system, in the time of start, get final product displaying video by start video process, start video process can be by automatic program identification.Start video process can create surface composer client, can realize the broadcasting of subsequent video source file by surface composer client.MediaPlayer service can be waken up by surface composer client, if Android system has carried out initialization in the time of initialization, surface composer client can directly create mediaPlayer object, and corresponding video source file is set.
Video source file can be advertisement video, film video, animation video etc., and user can set according to different hobbies.Video information provides many amount of information, and the form of expression is abundanter.
Two hardware show layers of general existence during due to video playback, and Video Layer priority is lower than UI show layers, therefore for Video Layer is visible, Video Layer must be carried out to top set operation, after step 102 creates local surface, need to figure layer priority corresponding to local surface be set to the highest.
Described step 106 among displaying video source file or afterwards, due to the reproduction time of video source file and the inconsistency of the time of android backstage loading service, therefore, need to judge the length of the two time, if the video playback time is more than or equal to the time of android backstage loading service, after waiting until that background service has started, discharge relevant resource and exit video playback process, otherwise, before video playback process exits on screen the last frame picture of display video always.
Specifically can realize before video playback process exits on screen the last frame picture of display video always by two kinds of modes:
1. by last frame picture is kept in buffer, then Video Layer is turned off, and this buffer is offered to interface display figure layer show, to realize before video playback process exits on screen the last frame picture of display video always;
2. by last frame picture is presented on Video Layer always, until start video process closes this Video Layer while exiting again, to realize before video playback process exits on screen the last frame picture of display video always.
First kind of way, due to after Video Layer is turned off, shows by buffer, and therefore, this method can cause film flicker once, is unfavorable for practical application, and therefore, the present invention generally takes the second way.
Shown in Fig. 2, the present invention also provides one. the video opening device based on Android system, comprise CPU, and described CPU comprises:
Video process initiation unit 200, for after the initialization of start Android system, starts start video process;
Client creating unit 201, for passing through start video process creation surface composer client;
Surface creating unit 202, for obtaining the demonstration information of current Android system and according to showing the local surface of information creating by surface composer client;
MediaPlayer unit 203, creates mediaPlayer object for passing through surface composer client, and the video source file of the needs broadcasting that mediaPlayer object is corresponding is set;
Setting unit 204, is set to the surfaceTexture of Video Layer for surfaceTexture corresponding to local surface;
Broadcast unit 205, for displaying video source file;
Judging unit 206, for judging whether the video playback time is less than the time of android backstage loading service, if be not less than, after waiting until that background service has started, discharge relevant resource and exit video playback process, otherwise, before video playback process exits on screen the last frame picture of display video always.
Described judging unit 206 is realized before video playback process exits on screen the last frame picture of display video always by two kinds of modes:
1. by last frame picture is kept in buffer, then Video Layer is turned off, and this buffer is offered to interface display figure layer show, to realize before video playback process exits on screen the last frame picture of display video always;
2. by last frame picture is presented on Video Layer always, until start video process closes this Video Layer while exiting again, to realize before video playback process exits on screen the last frame picture of display video always.
Described Surface creating unit 202 is creating after local surface, and direct figure layer priority corresponding to local surface is set to the highest, is set to visible by Video Layer.
Described mediaPlayer unit 203, before creating mediaPlayer object, can judge whether mediaPlayer service ready, if not then thread, waits for that service is ready, ready after, can create mediaPlayer object.
Described device is in the time of specific implementation, and with reference to content described in above method, described device can be completely achieved the flow process in described method.
The present invention also provides a kind of playback equipment, and described playback equipment comprises above-described video opening device, and described playback equipment comprises smart mobile phone, Web TV, Set Top Box, panel computer.
The above, be preferred embodiment of the present invention, and the present invention is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
