(4) whether, by judging video data type, analyzing this video streaming data packet is discernible video flowing;
(5) test analysis is carried out to the video flowing identified.
Further, in step (4) to the concrete steps that video data type judges be wherein: 1) if front four bytes of this video packets of data as " jP ", " moov ", " mdat ", " pnot ", " udta ", " ftyp ", " afra " wherein a kind of, be then mp4 form, otherwise be FLV form;
2) size being each section to the judging characteristic of MPEGTS video is fixedly 204 bytes, and whether the first byte of each section is 0x47;
Further, in step (5), the process of test analysis carried out to video flowing specific as follows: 1), to all video streaming data packet analyze its source data packet address, whether destination address, source port, target port be identical, if identical, series of video stream packets is reconfigured a link, thus be spliced into a virtual TCP video flowing, and the time series of reconstructed video stream;
2), real-time analysis video flowing, comprising removing the packet repeated, analyze each video streaming data packet time point, the delay skew of video, the time migration that receives;
3), calculate buffer time first time, player has the buffering of 5 seconds, with the time migration 5 seconds of video for benchmark, calculate receive video cost in 5 seconds time as buffer time;
4), at the playing process of backstage simulation player, set up the Buffer Pool of a video playback on backstage, receive the video flowing that should cushion as the criterion starting to play, be generally 5 seconds;
5), at the playing process of backstage simulation player, deducted the video data in a second every one second, check whether the data of lower buffering are less than buffer value simultaneously, illustrate cushioned if the data of current broadcasting are less than buffer value;
6) if find once to cushion, record is carried out, statistics buffering number of times;
7) if the data of current broadcasting are greater than buffer value, explanation has restarted to play, and this time difference is as buffer delay.
Further, the buffer value in described step 5) is 5 seconds.
Further, described mobile terminal comprises mobile phone and PAD.
Method of testing of the present invention, time delay error can be reduced, and video playback produced problem is judged, the video that all mobile terminals (mobile phone and PAD) plays accurately can be tested, the buffering number of times in video display process can be had a clear understanding of, buffer time, can be used for the play quality measuring video itself, can support to assess video display effect under different terminals, different network environments.
