Embodiments provide a kind of method of multi-media processing, be applied in terminal, for realizing making when not affecting multimedia definition as far as possible multimedia to adapt to current network conditions, ensure as far as possible multiple go out data.Fig. 1 is the flow chart of the method for a kind of multi-media processing in the embodiment of the present invention, as shown in Figure 1, comprises the following steps S11-S12:
According to current network conditions, step S11, judges whether multimedia current frame rate reaches and adjusts frame bar part.
Step S12, when multimedia current frame rate reach adjust frame bar part time, adjust multimedia frame per second, make multimedia current frame rate and current network conditions suitable.
In one embodiment, step S11 can be embodied as following steps M1-M3:
Step M1, determines the multimedia frame per second scope suitable with current network conditions.
Wherein, the multimedia frame per second scope of different network condition adaptations can be preset.Network condition available network mass parameter characterizes, and such as characterizes by network transfer speeds, bandwidth.Network condition is better, and multimedia frame per second value range is higher; Network condition is poorer, and multimedia frame per second value range is lower.Terminal can judge the quality of current network conditions according to current transmission speed and the network bandwidth.In addition, current network conditions also reflects by the multimedia fluency of current broadcasting, such as, when the multimedia fluency of current broadcasting is lower, explanation current network conditions is poor, then suitable with current network conditions multimedia frame per second scope is relatively low; Or when the multimedia of current broadcasting occurs blocking the situation of timing, also illustrate that current network conditions is poor, then suitable with current network conditions multimedia frame per second scope is relatively low.

In one embodiment, multimedia current frame rate reach frame bar part falls and time, step S12 can be embodied as following steps A1 or steps A 2:
Steps A 1, when multimedia current frame rate reach frame bar part falls and time, carry out frame-skipping reference according to the first predetermined number of intervals to multimedia, the first predetermined number of intervals meets the preferential condition with reference to I frame; Or,
Steps A 2, when multimedia current frame rate reach frame bar part falls and time, from last frame, abandon forward the frame number of the first predetermined number successively.
When carrying out falling frame, by above-mentioned two kinds of methods, frame is fallen to multimedia.Fall frame method for steps A 1, the first predetermined number of intervals meets the preferential condition with reference to I frame, the preferential I frame with reference to carrying important information when namely carrying out frame-skipping reference, abandons time important P frame.Or, first predetermined number of intervals also can be set as every a frame or every two frames, such as, multimedia current frame rate is 24 frames per second, when the first predetermined number of intervals is set as every a frame, multimedia adopts 1/2 frame-skipping reference, namely discards the frame number of half, and now multimedia frame per second is 12 frames per second; Or when the first predetermined number of intervals is set as every two frames, multimedia adopts 1/3 frame-skipping reference, now multimedia frame per second is 8 frames per second.Fall frame method for steps A 2, the first predetermined number can be set as 10 frames, such as, multimedia current frame rate is 24 frames per second, when multimedia current frame rate reach frame bar part falls and time, from the last frame of 24 frames, discard 10 frames successively forward, then multimedia frame per second is reduced to 14 frames per second.In addition, for avoiding multimedia to occur mosaic situation, can fall one by one, until frame per second is reduced to current network conditions suitable.Fall frame method for steps A 2, because P frame is secondary frame, I frame is main frame, therefore from back to front frame losing time preferentially abandon time important P frame, retain the I frame carrying important information, until abandoned by all P frames.
In one embodiment, multimedia current frame rate reach rise frame bar part time, step S12 can be embodied as following steps B1 or step B2:
Step B1, when multimedia current frame rate reach rise frame bar part time, increase multimedia frame number according to the second predetermined number of intervals; Or,
Step B2, when multimedia current frame rate reach rise frame bar part time, from last frame below increase the frame number of the second predetermined number successively.
When carrying out rising frame, carry out rising frame to multimedia by above-mentioned two kinds of methods: frame method is risen for step B1, second predetermined number of intervals can be set as every a frame or every two frames, such as, multimedia current frame rate is 7 frames per second, when the second predetermined number of intervals is set as every two frames, from the first frame of 7 frames, then increase by 1 frame every two frames, multimedia frame per second rises to 10 frames per second.Rise frame method for step B2, the second predetermined number can be set as 6 frames, such as, multimedia current frame rate is 7 frames per second, when multimedia current frame rate reach rise frame bar part time, from 7 frames below, increase by 6 frames successively in order, then multimedia frame per second rises to 13 frames per second.In addition, be more prone to owing to improving frame per second than reducing frame per second, can not as reducing the situation that occur mosaic frame per second, therefore, and can the increase of two frame two frames when improving frame per second, until frame per second is brought up to current network conditions suitable.
In one embodiment, after step S12, said method also comprises steps A 13-A14:
Steps A 13, when multimedia current frame rate reaches default minimum frame per second, switches to more low-grade resolution by multimedia current resolution, and multimedia current frame rate is switched to the highest default frame per second.
Steps A 14, when multimedia current frame rate reach frame bar part falls and time, reduce multimedia current frame rate, make the multimedia frame per second after reduction and current network conditions suitable.
In this embodiment, when multimedia frame per second is reduced to default minimum frame per second, still not suitable with current network conditions, then no longer reduce multimedia frame per second, but multimedia is switched to the more low-grade resolution presetting the highest frame per second.Such as, presetting minimum frame per second is 5 frames per second, presetting the highest frame per second is 24 frames per second, continue to fall frame when current network conditions is poor, when the frame per second of HD video is reduced to 5 frame per second, no longer fall frame, and be the SD video of 24 frames per second by video switch to frame per second, if current network conditions is still poor, then continue to fall frame from the frame per second of 24 frames per second.
In one embodiment, after step S12, said method also comprises step B13-B14:
Step B13, when multimedia current frame rate reach preset the highest frame per second time, multimedia current resolution is switched to more high-grade resolution, and multimedia current frame rate is switched to default minimum frame per second.
Step B14, when multimedia current frame rate reach rise frame bar part time, improve multimedia current frame rate, make the multimedia frame per second after raising and current network conditions suitable.
In this embodiment, when multimedia frame per second bring up to preset the highest frame per second time, still not suitable with current network conditions, then no longer improve multimedia frame per second, and multimedia switched to the more high-grade resolution of default minimum frame per second.Such as, presetting minimum frame per second is 5 frames per second, presetting the highest frame per second is 24 frames per second, continue when current network conditions is good to rise frame, when the frame per second of SD video brings up to 24 frame per second, no longer rise frame, and be the HD video of 5 frames per second by video switch to frame per second, if current network conditions is still good, then can continue to rise frame from the frame per second of 5 frames per second.
