Abstract： |
The invention relates to a method for video frequency speeding and backing and speed restoration based on frame coding image searching, which belongs to computer multimedia application technology field. The speed of speeding and backing of the video frequency flow is arranged as the n time speed, stop playing the audio frequency; processing the next frame of the video frequency according to the set speed, thus the speeding and the backing will be delayed, in order to control the speed of speeding or backing. The method is: the playing speed of the video frequency flow is normal; restores the video frequency playing; acquires the next frame of video frequency according to the normal speed; processes the next frame until the whole data are played completely. The view is clear when in speeding and backing, the process is simple, and the speed is stable. |
