(4), by video data type is judged, whether analyze this video streaming data packet is discernible video flowing;
(5) video flowing identifying is carried out to test analysis.
Further, wherein in step (4), the concrete steps to video data type judgement are: 1) if front four bytes of this video packets of data are the wherein a kind of of " jP ", " moov ", " mdat ", " pnot ", " udta ", " ftyp ", " afra ", be mp4 form, otherwise be FLV form;
2) size that is each section to the judging characteristic of MPEGTS video is fixedly 204 bytes, and whether the first byte of each section is 0x47;
Further, 1), whether all video streaming data packet are analyzed to its source data packet address, destination address, source port, target port identical in step (5), video flowing is carried out to the process of test analysis specific as follows:, if identical, a succession of video streaming data packet is reconfigured to a link, thereby be spliced into a virtual TCP video flowing, and the time series of reconstructed video stream;
2), real-time analysis video flowing, comprising the packet remove repeating, analyze the delay skew of each video streaming data packet time point, video, the time migration of receiving;
3), calculate buffer time for the first time, player has the buffering of 5 seconds, the time migration of video of take 5 seconds is benchmark, calculate receive video cost in 5 seconds time as buffer time;
4), at the playing process of backstage simulation player, on backstage, set up the Buffer Pool of a video playback, receive the video flowing that should cushion as the criterion that starts to play, be generally 5 seconds;
5), at the playing process of backstage simulation player, every one second, deduct the video data in a second, check whether the data of lower buffering are less than buffer value simultaneously, if the data of current broadcasting are less than buffer value, explanation has cushioned;
6) if find once buffering, carry out record, 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 buffering time 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, can reduce time delay error, and the problem that video playback is occurred judges, the video that can play all mobile terminals (mobile phone and PAD) is accurately tested, can have a clear understanding of the buffering number of times in video display process, buffer time, can be used for measuring the play quality of video itself, can support video display effect under different terminals, different network environments to assess.
