Step 4, the FTP server stores the audio and video frames in the PS format and the video files;
and 5, the universal player arranged at the client reads and plays the video files in the video file sharing directory.
Description of the whole flow scheme:
1: the universal FTP server is installed and deployed on a common home computer. Definition of FTP, for example (FTP Server common to FileZilla Server, wing FTP Server): file Transfer Protocol (file transfer protocol) for receiving and storing files, and in the present application, streaming of audio/video data is performed. After the FTP server is deployed, setting a corresponding user name, a corresponding password and a corresponding user authority (readable and writable), setting a shared directory of the FTP server, and completing the preparation work of the FTP service of the PC end.
2: PS format encapsulation of the audio/video stream is realized in the camera program.
PS flow definition: MPEG2-PS is a packaging container for multiplexing digital audio, video, etc. PS is an abbreviation of Program Stream. The program stream combines one or more elementary data streams (PES) that are packetized but have a common time reference into a single overall stream.
ES: elementary Stream (elementary stream) is an original elementary stream output from an encoder, and contains only information necessary for a decoder and close to an original image or an original audio. The original code stream for transmitting the single-channel video and audio signal is output by the compressor. The ES contains only one content data stream, such as video only or audio only, etc.
PES: packetized Elementary Streams (packetized ES), the packets formed by ES are referred to as PES packets, and are one type of data structure used to convey ESs. The PES stream is a data stream formed by processing the ES stream by a PES packetizer, and in this process, the operations of packetizing, adding header information, and the like (first packetizing the ES stream) are completed. The basic unit of a PES stream is a PES packet. The PES packet consists of a header and a payload. PS-Program Stream PS Stream consists of PS packets, and one PS packet consists of several PES packets (here, the ES is encapsulated in two layers). The packet header of the PS packet includes synchronization information and clock recovery information. One PS packet may contain at most 16 video PES packets and 32 audio PES packets with the same clock reference.
The camera program obtains the audio/video frames through the internal interface and then encapsulates the audio/video frames. The video frames are in H264 encoding format, the video I frames are encapsulated in (|PS header|PS system map|PES|data|PES data|PES data| … |) format, video non-I frame per (|PS header|PES|data|PES) data PES data …) format. And the audio frame is in an audio coding format of AAC, and the audio frame is packaged according to the format of (|PS header|PES|data|PES data|PES data| … |).
3: and transmitting the encapsulated PS stream data by adopting an FTP protocol:
the monitoring equipment performs the following operations through the written FTP code service interface:
a: the FTP user name and password are used for logging in the FTP server. B: a hierarchical directory of cameras at the FTP server (by date and camera ID) is created. C: video files are created (created in the mkv format [ various players can recognize ]). D: the monitoring device uploads the encapsulated audio/video frames in the PS format to the FTP server as a data carrier uploaded by the FTP (the first frame of the file is an I frame, and the audio/video frames encapsulated in the PS format are uploaded all the time in a round-robin manner), and the size of one file is generally limited to 30-40 minutes. E: closing the FTP server, and logging out of the FTP server. The whole file is uploaded.
4: the client uses a player (VLC, quick lightning, storm video and audio and other universal players) to play the video files uploaded to the FTP server at the PC end, and normal file playing is carried out.
Compared with the prior art, the application has the beneficial effects that:
1. compared with the storage of the SD card which is usually used by monitoring equipment, the method can discard the limitation that the video recording time caused by the limitation of the space of the SD card can only be stored for about 1 week, the FTP server only needs to have a large enough PC hard disk and can continuously store the data, the 6TB hard disk can generally store the monitoring data for 3 months, and the SD card is easy to damage when the large data is frequently written. According to the method, a user does not need to purchase the SD card independently, the safety is higher than that of the SD card, for example, the SD card of the camera is basically damaged and lost when damaged, the FTP private cloud is adopted, and even if the camera is damaged, the monitoring video is not damaged and lost.
2. Compared with the monitored local NVR, the application does not need the user to purchase NVR equipment and hard disk more, thereby reducing expenditure. And the method is simpler and more convenient than NVR deployment, and can be operated by a general user with less requirements on professional skills of the user.
3. Compared with an internet cloud storage mode, the method does not need users to pay expensive cloud storage cost per month, and is higher than the internet cloud storage safety, because once data are transmitted on the internet, the data are possibly intercepted, and privacy leakage risks exist.
The following examples are given to illustrate the application in a clear and complete manner, and are carried out by the following steps:
the first step: the personal PC computer uploads the FTP service program, configures the user name and the password, sets the shared directory, opens the viewable list of the shared directory, can build the subdirectory, and has readable, writable, additionally-writable and deletable permissions for file setting.
And a second step of: a universal player is installed, in this embodiment a storm video player is used.
And a third step of: in the configuration of the high-definition web camera, the user name and password of the FTP are associated, and the FTP video recording function is used, and the 24-hour daily video recording is configured.
Fourth step: the FTP service program waits for the high-definition web camera to upload audio and video monitoring data packaged in real-time PS format for half an hour.
Fifth step: and playing the PS-format encapsulated audio and video monitoring data uploaded to the FTP service program by using a storm video player.
In summary, the application provides a method suitable for home scenes and small shops, suitable for monitoring equipment to upload audio and video streams packaged by PS protocol in real time, wherein the FTP server receives the audio and video stream data and stores the audio and video stream data as real-time audio and video private cloud of video in real time, ensures the security of private data and can resist network jitter abnormality.
The foregoing is merely a preferred embodiment of the present application and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present application, which is also intended to be covered by the present application.
