Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below by accompanying drawing and embodiment, the present invention being further elaborated.However, it should be understood that specific embodiment described herein is only in order to explain the present invention, it is not limited to the scope of the present invention.
A kind of vod data processing method,
The video file of recording is saved as based on HLS protocol form M3U8 index file and some TS slicing files, is stored in locally stored module.
As the further optimization of such scheme, downloaded M3U8 index file and some TS slicing files by the Internet, aerial download channels and cable channel.
As the further optimization of such scheme, also include: access M3U8 index file by http request, at client downloads TS slicing files, and be preserve after MP4 file by TS slicing files transcoding.
Structured flowchart referring to a kind of Video Monitoring Terminal that Fig. 2, Fig. 2 are the present invention.A kind of Video Monitoring Terminal, including:
Video data acquiring module, for Real-time Collection video data；
Data processing module, saves as M3U8 index file and some TS slicing files by the video data of video data acquiring module Real-time Collection based on HLS protocol form；
Data memory module, stores the M3U8 index file processed through data processing module and some TS slicing files
First data communication module: set up communication by the Internet, aerial download channels and cable channel with client and be connected.
In this preferred embodiment, the video file of recording is saved as the file of HLS protocol form in local SD card by Video Monitoring Terminal.Start backstage http server for processing the order request of client at Video Monitoring Terminal, client install APP for playing/video file that preserves of foradownloaded video monitor terminal.The client of this preferred embodiment can be but be not limited to Android or iOS device.
HLS protocol is that Apple moves the stream media protocol of equipment development for iPhone.HLS protocol comprises a M3U8 index file and TS media slicing file etc..The video request program of HLS protocol has all been supported based on Android3.0+ and iOS3.0+.Android and iOS also supports hardware decoding video code model H.264.
A kind of Video Monitoring Terminal of this preferred embodiment runs http server for processing the order request of client.Assigned catalogue is if/mnt/sd/ is as the service root of HTTP.The video file of recording is saved under the service root of http server by video data acquiring module, and client accesses the M3U8 index file of HLS protocol with order video by http request.It is as follows that the Video Monitoring Terminal of this preferred embodiment runs false code:
Additionally, a kind of Video Monitoring Terminal of this preferred embodiment, video data acquiring module checks when starting and process/mnt/sd/cache catalogue under whether have the video file being not fully complete.This situation occur surprisingly delay when recorded video machine or power-off time.
First video data acquiring module creates [current time] .hls file under/mnt/sd/sd catalogue and is used for preserving TS and cuts into slices file and M3U8 describes file.
Video data acquiring module, video record timeslice can by user setup, and recording time sheet is 1～5 minute.
A kind of Video Monitoring Terminal of this preferred embodiment, TS section document time sheet is HLS protocol, and the TS section time is 10 seconds.Example: recording time sheet starts when current time 20160101121212, time length of a film is 1 minute, and the TS section time is 10 seconds.After sheet has been recorded between at this moment, under/mnt/sd/cache/20160101121212.hls/ file, the files such as 0.ts, 1.ts, 2.ts, 3.ts, 4.ts.5.ts and video.m3u8 can be comprised.
Structured flowchart referring to the client that Fig. 3, Fig. 3 are the present invention.A kind of video reads client and includes:
Second data communication module, sets up communication by the Internet, aerial download channels and cable channel with Video Monitoring Terminal and is connected；
Download request sending module, for sending the solicited message of request downloading video files to Video Monitoring Terminal, and the expression accepting to send after Video Monitoring Terminal downloads to corresponding video file according to the solicited message of request downloading video files can send the response of corresponding video file；
Client downloads module, for obtaining the data of video file of response from Video Monitoring Terminal, downloads TS slicing files according to the M3U8 index file of access request, and is preserve after MP4 file by TS slicing files transcoding；
Playing module, receives, according to client downloads module, the video data preserved and plays out.
Client end can pass through the URL of the protocol rule video file recorded by built-in player or third party's player program request.Android or iOS can directly use built-in player control to carry out video request program, and fluency during HD video is watched in the hardware decoder decoded video streams guarantee that built-in player uses platform relevant.In this preferred embodiment, after client and video monitoring end set up network connection, the URL format of client order video is:
Http: // [intelligent monitor system IP address]: [intelligent monitor system HTTP service port numbers/[order video time started] .hls/video.m3u8.Example: intelligent monitor system IP address is 192.168.100.1, http server operates in 80 ports, and the video time started is 20160101121212, then the HLS program request URL of this video is:
http://192.168.100.1:80/20160101121212.hls/video.m3u8
Based on the primary video file supporting to play TS form, for instance the primary local video file that cannot play TS form of iOS system, it is necessary to just can play by third party's player.
In order to facilitate user to download in mobile terminal, check, share video file, the TS form section file unloading of HLS protocol can be MP4 file when downloading by client downloads module.MP4 form is widely used in PC and mobile equipment as ISO/IEC14496-14:2003 standard.Android and iOS device can the broadcastings of primary support high definition mp4 file.In this preferred embodiment, the video file false code that client end downloads HLS protocol form is as follows:
Client downloads module reads the H.264 coding data in TS file and writes mp4 file, and owing to being made without the encoding operation of video, therefore the process of transcoding is very rapid.The bottleneck of client downloads module is network transfer speeds but not transcoding is consuming time.
It is the structured flowchart of a kind of video monitoring VOD system of the present invention referring to Fig. 1, Fig. 1, including Video Monitoring Terminal and client；
Described Video Monitoring Terminal includes: video data acquiring module, data memory module and data communication module；
Video data acquiring module, for Real-time Collection video data；
Data memory module, saves as M3U8 index file and some TS slicing files by the video data of video data acquiring module Real-time Collection based on HLS protocol form；
First data communication module: set up communication by the Internet, aerial download channels and cable channel with client and be connected；
Described client includes:
Second data communication module, sets up communication by the Internet, aerial download channels and cable channel with Video Monitoring Terminal and is connected；
Download request sending module, for sending the solicited message of request downloading video files to Video Monitoring Terminal, and the expression accepting to send after Video Monitoring Terminal downloads to corresponding video file according to the solicited message of request downloading video files can send the response of corresponding video file；
