The present invention provides a video data source playback method, a device and a system. The method comprises a step of obtaining sampling information for identifying a video data source to be played, a step of determining video data source breakpoint information for recording playing progress of the video data source to be played stored in advance according to the above sampling information, a step of playing the video data source to be played according to the playing progress corresponding to the determined video data source breakpoint information. The problem that the breakpoint information of the same video data source in different paths can not be shared in the prior art is solved and a user experience is influenced is solved, and the sharing of the breakpoint information among multiple same video data sources is realized, and the user experience is improved.
