1. A method for playing back a video at a multiple-speed, comprising:
obtaining first video data, wherein the first video data comprises key frames and non-key frames;
compressing the non-key frames of the first video data to generate second video data;
decoding the second video data to obtain decoded video data, and playing back the decoded video data at a multiple-speed according to a preset playback multiple-speed value;
wherein the method further comprises:
obtaining the playback multiple-speed value;
wherein the compressing the non-key frames of the first video data to generate the second video data comprises:
if the playback multiple-speed value is less than a preset multiple-speed threshold, compressing the non-key frames of the first video data to generate the second video data;
if the playback multiple-speed value is greater than or equal to the multiple-speed threshold, obtaining seeking frames of the first video data based on the playback multiple-speed value, and taking the seeking frames as the second video data.
