For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Playing progress rate control method of the present invention, is applied to the electronic equipment with display unit.Described electronic equipment can be mobile phone, panel computer or desktop computer, notebook computer etc.Described display unit can be the display on described electronic equipment.Described display unit shows the broadcast interface of video file.Described broadcast interface can be the broadcast interface that video reproduction program is corresponding.
Fig. 1 is the flow chart of playing progress rate control method embodiment 1 of the present invention.As shown in Figure 1, the method can comprise:
Step 101: the playing progress rate adjustment operation obtaining user's input;
Described broadcast interface can show time shaft.Described time shaft can show playing progress rate regulating block.Described playing progress rate adjustment operation can be the drag operation that user carries out described playing progress rate regulating block.Described playing progress rate adjustment operation also can be that user inputs reproduction time, thus video file is directly play from this reproduction time.
Step 102: based on described playing progress rate adjustment operation, generates the playing progress rate regulating command comprising the first video playback temporal information;
After user inputs playing progress rate adjustment operation, according to described playing progress rate adjustment operation, described first video playback temporal information can be determined.Such as, suppose that total duration of a video file is 10 minutes, when playing progress rate regulating block is adjusted to the centre position of time shaft by playing progress rate adjustment operation by user, can determine that the first video playback temporal information is 5 minutes.
Directly input reproduction time to realize the situation of playing progress rate adjustment operation for user, the reproduction time that just user can be inputted is as described first video playback temporal information.
Step 103: according to the frame of video that the time interval of the very first time point represented with described first video playback temporal information is the shortest, regulate the playing progress rate of described video file, to start to play described video file based on described frame of video.
According to the very first time point that described first video playback temporal information represents, the frame of video that the time interval of the very first time point represented with described first video playback temporal information is the shortest can be determined.Such as, when very first time that the first video playback temporal information represents, point was 3 minutes and 48 seconds, be 3 points of I frames of 45 seconds with the I frame that 3 points of time intervals of 48 seconds are the shortest.Now, the playing progress rate of described video file can be regulated, from 3 points of I frames of 45 seconds, play described video file.
In practical application, playing progress rate is later than the video content of point of the described very first time, and user may be not yet viewed.Therefore, in order to ensure not allow user omit the content of video file, play the frame of video that the time interval can put is the shortest from playing progress rate early than described very first time point and with the described very first time.
In sum, in the present embodiment, by based on described playing progress rate adjustment operation, generate the playing progress rate regulating command comprising the first video playback temporal information; According to the frame of video that the time interval of the very first time point represented with described first video playback temporal information is the shortest, regulate the playing progress rate of described video file, to start to play described video file based on described frame of video; Can put the playing progress rate of nearest frame of video to video file based on the very first time after regulating with user to regulate, degree of regulation is higher.
Fig. 2 is the flow chart of playing progress rate control method embodiment 2 of the present invention.As shown in Figure 2, the method can comprise:
Step 201: the playing progress rate adjustment operation obtaining user's input;
Step 202: based on described playing progress rate adjustment operation, generates the playing progress rate regulating command comprising the first video playback temporal information;
Step 203: determine the video file segments that point of the described very first time is corresponding;
In practical application, video file can be divided into multiple video file segments.Each video file segments can comprise multiple frame of video.When video file is the online video file play, can download successively according to the order of video file segments.Download just can play this video file segments after completing a video file segments.
Concrete, such as total duration is the video of 5 minutes, and be altogether divided into 10 video file segments, then the duration of each video file segments can be 30 seconds.When by playing progress rate adjustment operation playing progress rate regulating block to be dragged to 3 points and 45 seconds on time shaft as user, the time range of the video file segments that very first time point (3 minutes and 45 seconds) is corresponding be 3 minutes 30 seconds to 4 minutes whole between.
Step 204: judge whether the resolution data being cached with described video file segments, obtain the first judged result;
If user once adopted described electronic equipment to play described video file segments, or when described video file segments is downloaded to described electronic equipment in advance, described electronic equipment just can be cached with the resolution data of described video file segments.
Described resolution data can be the data of each frame of video that described video file segments comprises.Any frame of video in described video file segments directly can be found from described resolution data.
Step 205: when described first judged result is for being, obtains and the I frame that be positioned at described very first time point before the shortest with the time interval of described very first time point from described resolution data;
I frame (I frame) is also called Intra pictures (intra picture).I frame is also key frame.It is the important frame in interframe compression coding.Only use the data of I frame with regard to restructural complete image during decoding.I frame does not need to generate with reference to the data of other frame of video.
Specifically, in the process of mpeg encoded, frame of video can be divided three classes.That is, partial video frame is compacted into I frame; Part is compressed into P frame; Part is also had to be compressed into B frame.Wherein, I frame includes the total data of formation one width complete image.P frame and B frame are on the basis of I frame, carry out compressing the frame of video obtained.
Such as, the generation method of B frame is bi-directional predicted interframe compression algorithm.When a frame data frame is compressed into B frame, can compresses according to the difference of adjacent former frame, this frame and rear frame data and obtain B frame.The i.e. difference of B frame only minute book frame and front and back frame.Adopt the compression of B frame can reach the high compression rate of 200:1.
P frame is compressed by the P frame be positioned at before self or I frame.P frame method carrys out distilled edition frame data according to this frame and the difference of adjacent former frame (I frame or P frame).The method taking P frame and I frame to combine compression can reach higher compression and nothing significantly compresses vestige.
From the above, at I frame, B frame, in the frame of video of this three types of P frame, only has I frame independently can form complete image.The frame of video of other two types, all needs the data with reference to other frame of video just can form complete image.Therefore in the present embodiment, carry out the adjustment of video playback progress based on I frame, can guarantee that the image generated is complete video image, not by the impact of other video requency frame datas.
Step 206: based on described I frame, regulate the playing progress rate of described video file, to start to play described video file based on described frame of video.
Concrete, the video pictures of the current broadcasting of described video file can be adjusted to described I frame.
In practical application, in video file, general tens seconds can have an I frame.Suppose that user regulates the very first time, point was 5 minutes and 23 seconds time, the time interval of putting apart from this very first time the shortest and I be positioned at before point of the described very first time can be very the I frame of 5 minutes and 15 seconds.Now, just the playing progress rate of described video file can be adjusted to the 5th point 15 seconds, from the 5th point of I frame of 15 seconds, play described video file.
In the present embodiment, by based on described I frame, regulate the playing progress rate of described video file, can guarantee that the image generated is complete video image, not by the impact of other video requency frame datas.In addition, the frame of I described in the present embodiment is buffered in described electronic equipment, and being therefore adjusted to the speed that described I frame carries out playing also is more fast, can respond playing progress rate regulating command fast.
