A media stream processing method, comprising: receiving, by a first media receiving device, media streams, wherein the media streams comprise a first media stream and a second media stream, the first media stream is a stream which needs to be processed by the first media receiving device quickly and the second media stream is a stream which needs to be played by the first media receiving device normally; obtaining (201, 401), by the first media receiving device, quick processing indication information, from the server wherein the quick processing indication information is a media play delay, and the media play delay is a frame difference or time difference between the following two time points: a time point of sending an intraframe-coded frame in a current Group of Pictures, GOP, to the first media receiving device and a time point of sending multicast media streams in the intraframe-coded frame in the current GOP; calculating (202, 402), by the first media receiving device, at least one of a frame skip frequency for playing the media stream in the frame skip mode, a fast forward speed for playing the media stream in the fast forward mode and duration of decoding the media stream quickly according to the media play delay; processing (203, 403, 404, 405, 406), by the first media receiving device, the first media stream quickly according to the calculated result; and playing the second media stream normally so that media play progress of the first media receiving device is synchronous with media play progress of a second media receiving device, wherein the second media receiving device is configured to receive multicast media streams, and the first media receiving device and the second media receiving device are in the same multicast group; wherein the processing (203, 403, 404, 405, 406), by the first media receiving device, the first media stream quickly according to the calculated result comprises at least one of: playing, by the first media receiving device, the first media stream in a frame skip mode according to the frame skip frequency; playing, by the first media receiving device, the first media stream in a fast forward mode according to the fast forward speed; and decoding, by the first media receiving device, the first media stream quickly according to the duration. receiving, by a first media receiving device, media streams, wherein the media streams comprise a first media stream and a second media stream, the first media stream is a stream which needs to be processed by the first media receiving device quickly and the second media stream is a stream which needs to be played by the first media receiving device normally; obtaining (201, 401), by the first media receiving device, quick processing indication information, from the server wherein the quick processing indication information is a media play delay, and the media play delay is a frame difference or time difference between the following two time points: a time point of sending an intraframe-coded frame in a current Group of Pictures, GOP, to the first media receiving device and a time point of sending multicast media streams in the intraframe-coded frame in the current GOP; calculating (202, 402), by the first media receiving device, at least one of a frame skip frequency for playing the media stream in the frame skip mode, a fast forward speed for playing the media stream in the fast forward mode and duration of decoding the media stream quickly according to the media play delay; processing (203, 403, 404, 405, 406), by the first media receiving device, the first media stream quickly according to the calculated result; and playing the second media stream normally so that media play progress of the first media receiving device is synchronous with media play progress of a second media receiving device, wherein the second media receiving device is configured to receive multicast media streams, and the first media receiving device and the second media receiving device are in the same multicast group; wherein the processing (203, 403, 404, 405, 406), by the first media receiving device, the first media stream quickly according to the calculated result comprises at least one of: playing, by the first media receiving device, the first media stream in a frame skip mode according to the frame skip frequency; playing, by the first media receiving device, the first media stream in a fast forward mode according to the fast forward speed; and decoding, by the first media receiving device, the first media stream quickly according to the duration. playing, by the first media receiving device, the first media stream in a frame skip mode according to the frame skip frequency; playing, by the first media receiving device, the first media stream in a fast forward mode according to the fast forward speed; and decoding, by the first media receiving device, the first media stream quickly according to the duration.
