aggregating, by a video aggregation analysis server, similar video files in the video files downloaded offline, and storing an aggregation result into the transcoding aggregation result database, wherein

correspondingly, when the client chooses to play a video file on demand, if the video play format matching server finds no transcoded file suitable for playing on the client in the transcoding aggregation result database, the video play format matching server recommends to the client another video file that is in an aggregated relationship with the video file chosen by the client for playing on demand, so as to make the client choose whether to play the recommended video file on demand.

48. The method according to claim 45, comprising:

obtaining data information of an offline task download as the video file that needs transcoding.

49. The method according to claim 44, wherein:
