Description
Technical field
The present invention relates to field of video processing, more specifically, relate to a kind of method of carrying out the video location and playing through key frame.
Background technology
Each picture is a frame in the video file, but because the data volume of a frame picture is very big, so generally all adopted compression algorithm.Existing compression method has nothing in common with each other, and therefore causes compressing the different of back frame type.
In the method for video compression, compress every frame as a static image.When actual compression, can take various algorithms to reduce the capacity of data, wherein, I frame, P frame, B frame are modal.The I frame, the expression key frame must find key frame just can continue to play in the time of the film redirect.Be appreciated that complete reservation for this frame picture, during decoding because comprise complete picture, so only need these frame data just can accomplish.The P frame is represented is this frame and before the key frame or the difference of P frame; During decoding need with before the picture of buffer memory be superimposed with the difference of this frame definition, produce final picture, the P frame is the difference frame just; The P frame does not have the complete picture data, has only the data of the picture difference of former frame with it.The B frame is two-way difference frame, and what promptly the B frame was noted down is the difference of this frame and front and back frame, the B frame of decoding, and the buffer memory picture before not only will obtaining, the picture after also will decoding is obtained final picture through the front and back picture with stacks these frame data.
It is thus clear that the decoding algorithm of key frame and P frame is simple, the system resource that takies is fewer; It is just passable that as long as key frame own is accomplished, the P frame also only need decoder previous picture buffer memory some, when running into the P frame just use the picture of buffer memory is all right before; If video flowing adopts P frame and key frame; Decoder can be regardless of the data of back, the decoding while reading, linear travel.At present a lot of video files have adopted the B frame, because the record of B frame is the difference of front and back frame, can practice thrift more space than P frame; So, though file size has reduced, the efficient of decoder will descend; Because when decoding, not only to use the picture of buffer memory before, also to know the picture of next key frame or P frame; Promptly read pre decoding in advance, and the B frame can not lose simply, because the B frame has also comprised image information; If lose simply, and with before picture simply repeat, will cause frame losing.
The centre of two key frames can not have transition frames, but before and after the transition frames key frame is arranged certainly, because transition frames is attached to key frame.Key frame can be revised the content of this frame, but transition frames can't be revised the content of this frame.Can comprise polytype element or many elements such as shape, montage, group in the key frame, but the object in the transition frames can only be montage or independent shapes.
The method of film redirect at present generally adopts the software algorithm localization method, and the shortcoming of this method is: first will abandon the data of non-key frame, for example, abandon b frame or the p frame data downloaded, causes waste.Second is not high through the time accuracy of algorithm location; For example, in the process of playing first, if carry out redirect; Position through algorithm estimation redirect; But the position of being estimated might be inaccurate, even bigger with the jump location difference of reality, might cause the problem of playing failure or playback error.
