Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In the embodiment of the present invention, when performing video capture action, adopt the first code check recorded video, and monitor the size of recorded video, the size of recorded video reach first preset size time, adopt the second code check recorded video, when the size of recorded video reaches the video size that terminal supports, stop performing video capture action.
In order to technical solutions according to the invention are described, be described below by specific embodiment.
embodiment one:
Fig. 1 shows the flow chart of the maximized acquiring unit of a kind of video that first embodiment of the invention provides, and details are as follows:
Step S11, when performing video capture action, adopts the first code check recorded video.
Wherein, the data bits of unit interval transmission when code check is exactly transfer of data, unit is that kilobit is per second: kbps.
In this step, when terminal receives the video capture instruction that user sent by touch terminal or audio frequency, video capture action is performed, and adopt the first code check recorded video, this first code check can be the code check preset, or, be the code check by obtaining after the general code check of adjustment terminal.
Alternatively, when obtaining after the code check general by adjustment terminal, described when performing video capture action, adopt the first code check recorded video, specifically comprise:
A1, perform video capture action time, determine the product of the first proportionality coefficient and default code check, the product determined is as the first code check.This default code check is the code check that terminal is general, and such as, when the code check that terminal is conventional is 30 frames/second, this default code check is 30 frames/second; When the code check that terminal is conventional is 25 frames/second, this default code check is 25 frames/second.In this step, the first proportionality coefficient is greater than 0 and is less than 1, alternatively, this first proportionality coefficient can be 1/2, or is 1/4, when the product of the first proportionality coefficient and default code check is non-integer, round downwards or round downwards, and using the product after rounding as the first code check.
A2, according to described first code check recorded video.By reducing the code check of recorded video, the recording time of video can be extended, thus obtain more video content.
Step S12, monitors the size of recorded video.
When video record starts, Real-Time Monitoring or monitor the size of recorded video when preset interval time arrives, this preset interval time is less than 1 second.
Step S13, the size of recorded video reach first preset size time, adopt the second code check recorded video, described second code check is less than described first code check.
In this step, the second code check can be adopted to record reach first and preset the remaining video after size, or, adopt the second code check and other code checks jointly to record to reach first to preset the remaining video after size.
Alternatively, when the described size in recorded video reaches default size, adopt the second code check recorded video, specifically comprise:
B1, the size of recorded video reach first preset size time, determine the product of the second proportionality coefficient and default code check, the product determined is as the second code check; Described second proportionality coefficient is less than described first proportionality coefficient.This second proportionality coefficient can be 1/4, or is 1/8, and certainly, when the first proportionality coefficient is 1/4, the second proportionality coefficient is 1/8, to ensure that the second code check is less than the first code check.In this step, when the product of the second proportionality coefficient and default code check is non-integer, rounds downwards or round downwards, and using the product after rounding as the second code check.
B2, according to described second code check recorded video.
In above-mentioned B1 and B2, first default size is relevant with the maximum video size that terminal is supported, such as, the product of the maximum video size can supported 80% with terminal presets size as first, when judging that the size of recorded video is more than or equal to the first default size, adopting the second code check to record and being greater than video.
Alternatively, when employing second code check and other code checks record the remaining video after reaching the first default size jointly, after described employing second code check recorded video, comprising:
C1, judge the size of recorded video whether reach second preset size.Wherein, the second default size is greater than the first default size.When after employing second code check recorded video, if monitor the size of recorded video, then judge whether the size of recorded video is more than or equal to second and presets size, this second default size is relevant with the maximum video size that terminal is supported, such as, the product of the maximum video size can supported 90% with terminal presets size as second.
C2, the size of recorded video reach second preset size time, determine the product of the 3rd proportionality coefficient and default code check, the product determined is as third yard rate; Described 3rd proportionality coefficient is less than described second proportionality coefficient.3rd proportionality coefficient can be 1/16, or is 1/8, and certainly, when the second proportionality coefficient is 1/8, the 3rd proportionality coefficient is 1/16, to ensure that third yard rate is less than the second code check.In this step, when the product of the 3rd proportionality coefficient and default code check is non-integer, rounds downwards or round downwards, and using the product after rounding as third yard rate.
C3, according to described third yard rate recorded video.In this step, record the video reached after the second default size according to third yard rate.Such as, when second to preset size be the product of the maximum video size that 90% supports with terminal, according to the remaining video after 90% of the maximum video size of third yard rate recording terminal support.
Step S14, when the size of recorded video reaches the video size that terminal supports, stops performing video capture action.
In this step, when judging that the size of recorded video equals the maximum video of terminal support, stop performing shooting action.Further, after recorded video terminates, the video of recording is sent to other-end.
In first embodiment of the invention, when performing video capture action, adopt the first code check recorded video, and monitor the size of recorded video, the size of recorded video reach first preset size time, adopt the second code check recorded video, when the size of recorded video reaches the video size that terminal supports, stop performing video capture action.Due to the code check of the basis size dynamic conditioning recorded video of recorded video, and the code check after adjustment is less than the general code check of terminal, and code check is less, the time of video record is also longer, the content that can record is also more, therefore, makes the content recorded can reach the maximized video size of terminal support substantially, improve the satisfaction of user, improve the utilance of the maximized video size that terminal is supported.
Should be understood that in embodiments of the present invention, the size of the sequence number of above-mentioned each process does not also mean that the priority of execution sequence, and the execution sequence of each process should be determined with its function and internal logic, and should not form any restriction to the implementation process of the embodiment of the present invention.
