Therefore, the embodiment of the present application can obtain the historical record of the multimedia file played by the electronic device within the preset time period, where the multimedia file may include three types: picture format, audio format, and video format.

Step 207: Select a target multimedia format from the multiple multimedia formats according to the historical record.

In an embodiment, the target multimedia format can be determined according to the usage time of the above three multimedia formats within a preset time period. For example, in the past twenty days, the user has a total viewing time of 3 hours of pictures, and the user listens to audio. The total time is 8 hours, and the total time the user watches the video is 6 hours, it can be determined that the target multimedia form is an audio form.

Step 208: Process the video file according to the target multimedia form and play the video according to the processed video file.

In an embodiment, when the target multimedia format is the picture format, the video file may be subjected to multiple frame extraction processing to obtain a picture set, and the pictures in the picture set are played at a preset time interval . Specifically, you can first determine the key frames in the video file, such as the frame that displays the subtitles in the movie, and then extract the above key frames to obtain the picture collection, and then play it in a slideshow, such as one picture every 5 seconds .

In an embodiment, when the target multimedia format is the audio format, the video stream of the video file may be stopped, the screen of the electronic device may be closed, and the audio stream of the video file may be played. For example, it is forbidden to decode the video data stream of a video file, decode the audio data stream of the video file and output the decoded audio data stream to the audio channel. When the video data stream output is closed, only the audio data stream is output. Time will reduce resource consumption.
