Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
As shown in Figure 1, be the flow chart of flow media performance testing method embodiment one of the present invention, this method comprises:
When above-mentioned file is play in step 102, terminal program request, determine the performance parameter of stream media system according to the result of the above-mentioned file of terminal processes.
Because mobile network's particularity, the system bandwidth between terminal and the server can not keep relative stability, and bandwidth is because network environment can change at any time, and therefore high performance mobile stream media system must be supported the dynamic bandwidth adaption function.Utilize above-mentioned flow media performance testing method, can the test terminal and server between the dynamic bandwidth adaption function, online ability to play that also can the test terminal, wherein during the dynamic bandwidth adaption function between test terminal and server, step 101 is specially: server provides many speed content MRC file of many rate adapted to terminal, step 102 is specially: when above-mentioned many speed content MRC file is play in the terminal program request, the playback rate that dynamically shows above-mentioned many speed content MRC file on terminal screen is determined the dynamic bandwidth adaption function of server and terminal room according to above-mentioned playback rate; During the online ability to play of test terminal, step 101 is specially: server provides a plurality of video files to terminal, and above-mentioned a plurality of video files are represented relevant parameters such as different video playback speed, frame number, video size respectively; Step 102 is specially: when above-mentioned video file is play in the terminal program request, obtain the maximum of the relevant parameter that terminal supports, determine the online ability to play of terminal according to above-mentioned maximum; In order to simplify testing procedure, guarantee test mass simultaneously, video file can comprise relevant parameter as shown in table 1.
Table 1 video measurement file
| Playback rate | Video size | The video frame number | File format |
| ??384K | ??240*320 | ??30Fps | ??MP4 |
| ??384K | ??240*320 | ??15Fps | ??MP4 |
| ??128K | ??240*320 | ??30Fps | ??MP4 |
| ??128K | ??240*320 | ??15Fps | ??MP4 |
| ??384K | ??176*144 | ??30Fps | ??MP4 |
| ??128K | ??176*144 | ??15Fps | ??MP4 |
| ??384K | ??240*320 | ??30Fps | ??3GPP |
| ??384K | ??240*320 | ??15Fps | ??3GPP |
| Playback rate | Video size | The video frame number | File format |
| ??128K | ??240*320 | ??30Fps | ??3GPP |
| ??128K | ??240*320 | ??15Fps | ??3GPP |
| ??384K | ??176*144 | ??30Fps | ??3GPP |
| ??128K | ??176*144 | ??15Fps | ??3GPP |
At table 1, if terminal can support that the highest playback rate of MP4 file is 128K, maximum video size is 240*320, and maximum frame number is per second 30 frames, and then this terminal can online playback rate be that 128K, size are that 240*320 and frame number are the video file of per second 30 frames.
In addition, before carrying out above-mentioned steps 101, can also test the code efficiency of server, for example different servers carries out compressed encoding for same avi file, suppose that source file is the X byte, with this avi file difference boil down to 3GPP form and MP4 form, keep identical (for example same video size for different server compresses parameters, video rate, frame number and audio rate etc.), for the file byte-sized behind the boil down to 3GPP is the Y byte, file byte behind the boil down to MP4 is the Z byte, then the 3GPP code efficiency of this server is (X-Y)/X*100%, and the code efficiency of MP4 is (X-Z)/X*100%; Respective coding efficient is high more, illustrates that the coding efficiency of server is good more; Under the good situation of the coding efficiency of server, can carry out above-mentioned steps 101 and step 102.
