The video file downloading method provided by the present application is explained by a plurality of embodiments as follows.
Fig. 3 is a flow chart of a video file downloading method according to an embodiment of the present application; the method is applied to the terminal device in fig. 1, as shown in fig. 3, and the method may include:
S301, responding to the operation of downloading the video file, which is executed by the user on the playing software of the terminal equipment, and determining whether the USB flash disk is inserted into the terminal equipment.
The playing software may be an application software pre-installed on the terminal device, and the user may click a trigger icon, such as a playing icon, a pause icon, a fast forward icon, or a download icon, in the playing software to obtain a video file stored in the server, and perform online playing or downloading operation on the obtained video file.
Alternatively, before responding to the operation of downloading the video file performed by the user on the playing software of the terminal device, the following steps may be performed:
the first step, the user needs to click on the icon of the playing software installed in the terminal device, enter the playing software, click on the icon of the video file to be played or downloaded selected by the user, and the terminal device can obtain the necessary information of video playing correspondingly.
Wherein, the necessary information of the video at least comprises: file identification, file acquisition address, file format, file code rate, file playing time length, etc.
The following is a simple introduction to the "video necessary information", and the file identifier is used for uniquely identifying a certain video file; a file acquisition address comprising: the uniform resource locator (Uniform Resource Locator, URL for short) address of the file is a physical address for acquiring the video file from the internet resource, and corresponds to playing the video online; the file format may be audio-video interlaced format, and the file code rate is the number of data bits transmitted per unit time of video file data, for example, 128 kilobits per second, or 128kbps.
And secondly, the terminal equipment sends a request for acquiring the video file to the server according to the acquired video necessary information, and requests a network channel and tries to access the acquired video file by using the URL address of the video file.
In one implementation, for example, if the network is not open, then network resources cannot be accessed.
In another implementation, for example, if the network connection is normal, the network resources may be accessed normally to obtain the video file.
And thirdly, the server executes playing authentication processing to confirm whether the playing software has the authority for downloading and playing the video file.
For example, the user can log in the playing software installed on the terminal device to determine whether the playing software has the authority for downloading and playing the video file, thereby realizing the authentication operation of the playing software.
If the user can log in the playing software by using any mode of account number + password or account number + short message verification code, and synchronize the user information, program information and the like to an account center in the server to verify whether the user has the authority to watch the program.
After the third step is performed, if the server confirms that the playing software has the right to download and play the video file, the user may perform an operation of downloading the video file on the playing software of the terminal device.
For example, after confirming that the user has the authority to watch the program, when the user needs to download the video file to the usb disk, the user may click on a download icon in the playing software, and the terminal device determines whether the user inserts the usb disk into the terminal device in response to the operation of downloading the video file triggered by the user in the playing software.
S302, if the USB flash disk is inserted into the terminal equipment, acquiring a key authentication file in the inserted USB flash disk.
In general, a terminal device has functions of identifying insertion, removal, reading, storage of a usb disk file, and the like.
The key authentication file is pre-stored in the USB flash disk and is used for identifying whether the USB flash disk inserted into the terminal equipment has downloading permission. It should be noted that, the key authentication file only supports a read-only mode, so that a user cannot copy, cut, delete and the like the key file, so that the USB flash disk has specificity, and the user can only download the video file into the specific USB flash disk, thereby avoiding the user from privately making a pirated USB flash disk according to the key authentication file.
In one implementation manner, for example, when the terminal device recognizes that the specific usb disk is inserted, a key authentication file stored in the usb disk in advance may be acquired, and whether the usb disk is a designated downloaded usb disk may be determined according to the key authentication file, so as to ensure that a video file downloaded into the usb disk is not leaked.
S303, verifying the validity of the key authentication file to obtain a verification result.
For example, the verification information stored in the obtained key authentication file may be matched with the verification information stored in the terminal device, so as to determine whether the key authentication file is valid, and obtain a verification result.
S304, if the verification result is that the verification is successful, the video file is downloaded to the inserted U disk.
For example, if the verification information stored in the key authentication file is successfully matched with the verification information stored in the terminal device, it can be determined that the usb disk has the right to download the video file, and the video file can be downloaded to the inserted usb disk.
At this time, the server decodes the URL address of the video file to obtain a real play address of the video file, obtains the video file to be downloaded from the real play address in the form of a file stream, returns the obtained video file to the terminal device, and the terminal device responds to the video file downloading operation executed by the user to download the video file to the usb disk in a sequential streaming mode, so that the user can watch the video file online while downloading the video file.
After the video file is downloaded to the USB flash disk, the USB flash disk can be inserted into other terminal equipment with a display function, normal play of the video file in the USB flash disk is realized, the requirement that a user needs to download video content to the USB flash disk and bring the video content to an outdoor environment for watching is met, the experience degree of the user is improved, meanwhile, the video file can be truly protected, and the potential safety hazard that the video file leaks due to the playing mode of the USB flash disk is avoided, so that the playing and downloading safety and reliability of the video file are effectively improved.
It should be noted that, the video files downloaded to the usb disk only support read-only and delete operations, but not copy, cut, etc., and once the key files in the usb disk are destroyed, the video files downloaded to the usb disk will not be playable.
In summary, the embodiment of the present application provides a method for downloading a video file, which includes: responding to the operation of downloading video files, which is executed by a user on playing software of the terminal equipment, and determining whether the USB flash disk is inserted into the terminal equipment; if the USB flash disk is inserted into the terminal equipment, acquiring a key authentication file in the inserted USB flash disk; verifying the validity of the key authentication file to obtain a verification result; and if the verification result is that the verification is successful, downloading the video file to the inserted U disk. In the scheme, whether the USB flash disk has downloading permission is verified according to the key authentication file, if verification is successful, the video file is downloaded to the inserted USB flash disk, the USB flash disk is inserted into other terminal equipment with a display function, normal playing of the video file in the USB flash disk is realized, the requirement that a user needs to download video content to the USB flash disk and take the video content to an outdoor environment for watching is met, the experience of the user is improved, meanwhile, the video file can be truly protected, and the potential safety hazard that the video file leaks due to the fact that the playing mode of the USB flash disk is used is avoided, so that the playing and downloading safety and reliability of the video file are effectively improved.
Optionally, the key authentication file includes: the verification code to be verified and the channel number to be verified.
The verification code to be verified can be a static verification code, and the channel number to be verified can be a channel number of playing software.
In this embodiment, for example, the key authentication file may be formed by a specified verification code and a channel number of the playing software, and the key authentication file is used to perform key authentication processing on the usb disk, so that common piracy cannot decrypt the key authentication file, and leakage of the video file downloaded to the usb disk can be effectively prevented.
FIG. 4 is a flowchart illustrating another method for downloading video files according to an embodiment of the present disclosure; step S303 described above: the validity verification is carried out on the key authentication file to obtain a verification result, which comprises the following steps:
s401, judging whether the verification code to be verified is matched with the target verification code of the playing software, and judging whether the channel number to be verified is matched with the target channel number of the playing software.
The target channel number is formed by combining channel name abbreviation of playing software, keys of the playing software and release date of the playing software.
Alternatively, the channel name abbreviation is composed of numbers and letters, e.g., the channel name abbreviation may be SN1008; the key of the playing software is a unique identifier possessed by the playing software.
It should be noted that, the playing software is in different channels, for example, the corresponding channel numbers are different, the same playing software runs on two different terminal devices, namely, terminal device a and terminal device B, and the terminal device a and terminal device B belong to products of different operators, and correspondingly, the same playing software has two different channel numbers, so that one authorization can be ensured to prevent file leakage.
The target verification code can be an operator-specified verification code, the verification code to be verified in the key authentication file can be compared with the target verification code of the playing software, whether the verification code to be verified in the key authentication file is identical to the target verification code of the playing software is confirmed, and if the verification code to be verified in the key authentication file is identical to the target verification code of the playing software, the verification code to be verified in the key authentication file can be confirmed to be matched with the target verification code of the playing software.
And comparing the channel number to be verified in the key authentication file with the target channel number of the playing software to confirm whether the channel number to be verified in the key authentication file is the same as the target channel number of the playing software, and if so, determining that the channel number to be verified in the key authentication file is matched with the target channel number of the playing software.
In this embodiment, by simultaneously determining whether the verification code to be verified matches the target verification code of the playing software and whether the channel number to be verified matches the target channel number of the playing software, authentication processing is performed on the key authentication file of the usb disk inserted into the terminal device, so as to confirm whether the usb disk has the authority to download the video file.
S402, if the verification code to be verified is matched with the target verification code and the channel number to be verified is matched with the target channel number, determining that the verification result is verification success.
For example, if the verification code to be verified is matched with the target verification code, it may be determined whether the usb disk inserted into the terminal device has the right to download the video file, and the usb disk may be considered as a designated download storage device, i.e. the requirement for downloading the video to the usb disk is supported.
S403, if not, determining that the verification result is verification failure.
For example, if authentication of the key authentication file in the usb disk fails, a prompt message may be output to notify the user that the authentication of the usb disk inserted into the terminal device fails, and the user may insert the designated usb disk to perform the downloading operation of the video file.
Optionally, after determining whether the usb disk is inserted into the terminal device, the method further includes: if the USB flash disk is not inserted into the terminal equipment, outputting prompt information which is used for prompting a user to insert the USB flash disk.
In another implementation manner, for example, if the terminal device recognizes that the usb disk is not inserted, the user is prompted to insert the usb disk into the terminal device, and ready to download the video file.
After confirming that the playing software installed in the terminal device has the authority to download and play the video file, the user can download and play the acquired video file at the same time, and the user can perform various operations such as downloading only, not playing, not downloading only, playing only, and the like on the acquired video file.
It should be noted that, if the user needs to download the video file to the designated usb disk, before the video file is played, an operation request for downloading the video file needs to be executed on the playing software of the terminal device, so as to complete the operations of "confirm whether the usb disk is inserted into the terminal device" and "authenticate the key authentication file in the usb disk".
For example, if the user does not perform the operation request for downloading the video file on the playing software of the terminal device before the video file is played, that is, the operation of "confirming whether the usb disk is inserted on the terminal device and authenticating the key authentication file in the usb disk" is not completed, but when the video file is played in half, the user needs to download the video file to the designated usb disk, and then performs the operation request for downloading the video file is invalid.
The steps of online playing the video file obtained by the application are described in detail through the following embodiments.
