Wherein, source video sequence information includes but not limited to: a kind of or any multiple combination in control point ID, control point longitude and latitude, video initial time, video duration and control point title.
S104, in application, during video file, obtain the source video sequence information at video file end for follow-up business logic.
Another kind of preferred version as the present embodiment, follow-up business logic is used the combination in any that includes but not limited to following several modes: according to application demand, source video sequence information is saved in video relative recording, with mode word, is presented on video or on map and marks.According to application demand, source-information is saved in video recording relative recording.When user uses these files, application system can show source-information with mode word, or directly on map, marks source-information.
Another kind of preferred version as the present embodiment, the source video sequence information of obtaining video file end also comprises for follow-up business logic: when video file is carried out to montage, from video file, read source video sequence information, source video sequence information is written to the end of the video file of new montage.That is to say, to comprising of downloading by the embodiment of the present invention any one section of video file in the video file of source-information carry out montage and save as after new video file, source-information is further saved in to the end of the video file of new montage, thereby guarantees to record all the time in the distribution afterwards of this video file and circulation process the source-information of this video file.The method of reviewing video file source that the embodiment of the present invention provides, when obtaining file from video monitoring platform, source-information is appended in video file, during application video, from video file, extract source-information, automatically for customer analysis video provides geographical space and temporal information, realize and in video distribution and circulation process, automatically record all the time the source-information of this video, without user in each artificial judgment and safeguard source video sequence information while using video file.
Refer to Fig. 2, the method for a kind of downloading video files that the preferred embodiment of the present invention provides comprises:
The download parameters that S1022, receiver, video monitor supervision platform send, and according to download parameters downloading video files.
Wherein, download parameters comprises source video sequence information.
Specifically, download and download after video clip to large-scale video monitoring networking platform or small-sized supervisory control system request, video monitoring networking platform is to the transmission series of parameters that downloads, such as: control point ID, need the initial time, video recording duration, control point title, control point longitude and latitude of the video recording downloaded etc.Receive after these parameters, start to carry out downloading task according to download parameters.
S1024, convert each field of source video sequence information to byte arrays, each byte arrays is spliced into byte serial, before byte serial, increase origin identification, after byte serial, increase and finish sign, obtain source-information byte serial.
Specifically, download parameter relevant to source video sequence in download parameters, such as video time started, video duration, control point ID, control point title, control point longitude and latitude etc. are encapsulated in a byte serial, this byte serial comprises following components:
Origin identification: 55AAAA55 (four bytes represent to come segments of source data to start)
Control point ID:00000101 (four bytes represent control point ID=257)
Tetra-bytes of control point longitude: 33e3143(, represent that control point longitude is 129.8875)
Control point latitude: fb dc442 (four bytes represent that control point latitude is 33.2158)
