Fig. 1 is a schematic view of an application scenario of the android system-based encrypted video offline playing method in an exemplary embodiment of the present application, a hardware carrier of the android system-based encrypted video offline playing method in the embodiment of the present application is an electronic device 100, and the electronic device 100 may be any intelligent terminal, for example, a computer, a mobile phone, a tablet computer, an interactive smart tablet, a PDA (Personal Digital Assistant), an e-book reader, a multimedia player, and the like. An Android (Android) operating system runs on the electronic device 100, and in the embodiment of the application, offline playing of an encrypted video is realized through a native player VideoView based on the Android system.
The VideoView in the embodiment of the present application is implemented based on the software client 110 in fig. 1 as a control, where the client 110 may be a software program APP installed in the electronic device 100, and in some implementation manners based on a B/S architecture, the software client 110 may also be a web application, and the present application takes the client 110 as an example for description.
The bottom layer implementation of native player VideoView120 based on android system is MediaPlayer, the MediaPlayer class is an important component in android multimedia framework, and through this class, we can acquire, decode and play audio and video with minimum steps. It supports three different media sources: local resources, internal URIs and external URLs (streams).
When playing a video stream on a network, MediaPlayer supports two protocols, HTTP and RTSP, the biggest difference between these two protocols is that the RTSP protocol supports the playing of real-time streaming media, but the HTTP protocol does not support. Since the underlying implementation of VideoView is MediaPlayer, the VideoView player also supports both protocols.
However, protocols (which do not support RTMP, MMS, etc.) and encapsulation formats supported by the Android native mediapalette are limited, and encrypted video cannot be played.
Based on the above technical problem, as shown in fig. 2, an embodiment of the present application discloses a flowchart of an encrypted video offline playing method based on an android system, where the method is executed by a client, and includes the following steps:
s201, a local server is established in the terminal equipment where the client is located.
In the embodiment of the application, the local Server is an HTTP Server, and the android system creates a local Server for monitoring the designated port in real time in advance, and preferably, the local Server calls a Java Server Socket to create after the client starts up or detects a play request.
And the encrypted video is stored in the electronic equipment where the client is located.
S202, acquiring an encrypted video data request sent by a local server, wherein the encrypted video data request is sent by the local server according to a playing request of a player control based on VideoView, and the playing request indicates an encrypted video file stored in a terminal device where a client is located.
The client may be that a player control based on VideoView is set in some pages of the client, and when a user opens a page in the client in which the player control is set, the player control automatically loads, and sends a play request according to a play source of an encrypted video preset in the player control, and the local server obtains the play request.
And the local server communicates and transmits data with the client and the player control based on the VideoView according to the HTTP protocol. In some examples, the play request includes a local storage address of the encrypted video at the terminal device where the client is located.
In some examples, the local server may directly obtain the play request of the player control based on the VideoView by listening, or may obtain the play request of the player control based on the VideoView received and forwarded by the client.
In some examples, after receiving the play request, the local server sends an encrypted video data request to the client according to the local storage address of the encrypted video in the play request, so as to obtain the encrypted video file stored in the terminal device where the client is located.
S203, decrypting the encrypted video file according to a preset secret key, converting the encrypted video file into a plurality of HTTP files, and sending the plurality of HTTP files to the local server, so that the local server sends the plurality of HTTP files to the player control based on the VideoView for playing.
In this embodiment, the client firstly verifies the application signature, then decrypts through an encryption algorithm of the jni (java native interface) end to obtain a decryption key, and decrypts the encrypted video file through the decryption key. After the client decrypts the encrypted video file through the decryption key, the encrypted video file is converted into a plurality of HTTP files, one thread is created, or a plurality of sub-threads are started to send the HTTP files to the local server.
The method comprises the steps that a client side divides an encrypted video file into small files based on HTTP, decrypts the HTTP files and sends the files to a local server, specifically, the HTTP files are TS video slice files, and the client side decrypts the TS slice files.
According to the method and the device, the HTTP protocol is adopted to complete sending and processing of the requests, therefore, the player control based on the VideoView needs to send a plurality of playing requests to the local server, an object pointed by each playing request is a TS video slice file of the encrypted video file, and the client divides a corresponding TS video slice file according to each playing request, decrypts the TS video slice file and sends the TS video slice file to the local server.
The client may send the video data packets from the client to the local Server through a preset Socket (Server Socket). In this step, the client creates a local Server Socket, connects to a localcocket of the local Server, converts the encrypted video file into a Socket (Server Socket) video data packet, and sends the video data packet to the Server through one or more threads. Because the socket directly uses the memory mapping mode to transmit data, when the client sends the video data packet to the local server, the transmission is stable and the transmission efficiency is high.
The local Server may also send the video data packet from the local Server to the VideoView-based player control through a preset Socket (Server Socket) for playing.
In the embodiment of the application, the local server creates one thread or a plurality of sub-threads to receive the TS video slice file to be played, and sends the TS video slice file to the player control based on the VideoView through the HTTP protocol for playing.
In some examples, the android system logs off the local server after the playback of the entire video file is completed.
In the embodiment of the application, a local server is pre-created in an android system, the local server sends an encrypted video data request to a client according to a playing request acquired from a player control based on a VideoView, the client decrypts and converts a local video file into a plurality of TS video slice files, sending the TS video slice files to a local server, sending the TS video slice files to the player control based on the VideoView to be played, because the client, the local server and the player control based on the VideoView realize the simultaneous decryption and playing of the local encrypted video file, the local video file does not need to be integrally decrypted and converted into a file format supported by the player control based on the VideoView, the encrypted video file stored in the local server has no risk of being copied and stolen after being decrypted, meanwhile, the playing process is safer and simpler by using the player control based on the VideoView.
In an exemplary embodiment, the playing request includes a storage address of the indicated video data, and the obtaining, by the local server, the playing request of the player control based on the VideoView includes: the client maps the storage address to the port of the local server so that the local server obtains the playing request. And the player control based on the VideoView sends the playing request to the local server, and the local server sends an encrypted video data request to the client according to the playing request and the storage address of the video data indicated in the request. For example, the client translates the encrypted video local file address file path to the local server address http:// localhost: port// file path.
In order to improve the decryption and playing efficiency, in an exemplary embodiment, before the client acquires the playing request of the player control based on the VideoView, only a few header bytes of the video file are encrypted, and an encrypted video file is generated. The number of header bytes may be one, or more, and in other embodiments may be other numbers, such as 99. In some other examples, portions of the content of the video file may be encrypted in other ways, such as the header and trailer portions, or the middle portion of the content.
In an exemplary embodiment, the encrypted video file of the embodiment of the present application uses a symmetric encryption algorithm to encrypt several header bytes of the video file, and the same key can be used for both encryption and decryption of information by using an encryption method of a single-key cryptosystem. Specifically, the data Encryption standard can be des (data Encryption standard): the data encryption is standard, the speed is high, and the method is suitable for occasions where a large amount of data is encrypted; 3DES (triple DES): based on DES, three different keys are used for encrypting one block of data for three times, so that the intensity is higher; or aes (advanced Encryption standard): the advanced encryption standard is the next generation encryption algorithm standard, has high speed and high security level, and supports encryption of 128, 192, 256 and 512 bit keys.
