The method is to set the video player to play the video player module 120 in the audio and video application 100. The material source URL IP address is 127.0.0.1; Step 4, S204 user triggers the audio and video playback APP 100 to customize the video playback control function, the video playback APP 100 performs the Seek jump function provided by the native video player API. . The Seek jump function is to send a video playback control command to the specified video stream server to notify the video stream server to jump the video content playback time point of the transmission to the time specified by the parameters in the incoming Seek function. . The time specified by passing in the Seek function parameter can be arbitrary. Through the Seek function, the video playback control command is sent to the video playback control command agent servo module 110; in step 5, the S205 video playback control command mediation servo module 110 analyzes the video playback control command and hides the extended function instruction code. The video playback control command mediation processor module 110 detects the received video playback control command through the audio and video streaming instruction parsing modification unit 111, and if the user triggers the video playback, the custom extended video playback control function on the APP 100 If it is issued, the instruction code (symbol or value) corresponding to the extended function is defined in the received video playback control command; step 6, the S206 video playback control command is sent to the servo module 110 to transmit the modified video playback control. The video stream server 200 is instructed. The action is the video playback control command.

The audio and video player module 120 in the audio and video playback APP 100 plays the video and audio content according to the received audio and video content data.

Embodiment 1:

For example, to expand the Android video playback control function and use the RTSP protocol, please refer to Figure 2 and Figure 3. The media operator establishes a video streaming server 200 based on the RTSP protocol and sets an IP address of the server (such as 59.144.24.78) to place a video content media (data file media.mp4) in the video and audio. The data stream server 200 is in a storage medium. And develop a Android video playback service application (APP 100) to play media.mp4. In the audio and video playback APP 100, the native audio and video player module 120, the audio and video playback control command, the intermediary servo module 110 and the video and audio streaming server 200 are connected to the audio and video playback control protocol by RTSP, and the native video player module is used. 120 sets the video material source location URL to rtsp://127.0.0.1/media.mp4 to direct its own video playback control command intermediary servo module 110. In addition to the start of playback function, the audio and video playback APP 100 implements two video playback control functions of the first five seconds 121 and twice the fast rotation 122 on the audio and video playback APP 100. The function of the first five seconds 121 can be directly used by the seekTo() API function provided by the Android native video player. When the user presses the previous five seconds button, the video playback APP 100 program executes the following command mediaplayer.seekTo (mediaplayer.getCurrentTime()+5000); mediaplayer represents an Android native video player object in the audio and video playback APP 100. First, get the current movie playback time mediaplayer.getCurrentTime() and add 5000 milliseconds as the incoming seekTo function. The parameter is used to achieve the purpose of jumping forward five seconds of the movie time being played. The other two-time fast-transfer 122 function is implemented in the manner mentioned in the present case, and is implemented in the following specific manner. When the user presses the double-fast forward 122 function button when the video content has started to be played, a standard RTSP command is sent by calling the seekTo() function (for example, execute seekTo (5200), where 5200 is a random setting value. ), and in the video playback APP 100, the user has pressed twice the fast-forward 122 key event. The audio and video playback APP 100 executes the seekTo (5200) function, and the native video player module 120 transmits the audio and video playback control command to the mediation servo module 110, as shown in the following figure A:

The content of the RTSP PLAY command contains a specified Range:npt value, which is intended to require the RTSP protocol-supported video stream server to jump the video content being played to the number of seconds specified by npt, in this case 5.2 seconds. The value of one of the different npt decimal points is defined, which can represent different control functions npt=xx.x111 (fast forward 2X), npt=xx.x112 (fast turn 4X), npt=xx.x113 (fast turn) 8X), npt=xx.x121 (reverse 2X), npt=xx.x122 (inverted 4X), npt=xx.x123 (inverted 8X), npt=xx.x131 (previous channel), npt=xx.x132 ( The latter channel), after the instruction is received by the video playback control command agent servo module 110, it is known from the previous record that the command event is triggered by the user pressing twice the fast-rotating 122 key, and is modified by the video stream stream instruction. Unit 111 changes it to Figure B below:

In addition to forwarding the RTSP command to the video data stream server 200, the original video material source location URL IP is changed from the original 127.0.0.1 to the IP 59.144.24.78 of the video data stream server 200, and the npt value is also from 5.2. Change to 5.2111. Wherein 111 is defined in advance, hidden in the RTSP PLAY instruction, representing twice the instruction symbol or value. The principle of operation is that the npt value sent by the call to the SeeTo() function has a certain degree of precision. For Android, for example, only one digit below the decimal point. We will extend the instruction to represent the symbol or value by using the seekTo() function to append the symbol or value represented by the instruction to one of the decimal points of the npt value of the RTSP PLAY instruction it issued. The extended function code is hidden in this instruction. Similarly, other symbols or values can be defined to represent other functions (such as 112 for reversing four times, 113 for up-switching channels, ..., etc., depending on the system developer's design to define different audio and video playback control functions) to be hidden by seekTo() Issued within the RTSP PLAY instruction. The video playback control command intermediary media module 110 forwards the RTSP command that has been embedded in the extended instruction code to the video stream server 200. After receiving the command, the video streaming server 2 parses the content of the command through the video streaming instruction parsing module 210. If the command is found to contain a hidden command symbol or value, the video data stream communication module 220 is notified to perform the symbol. Or the audio and video stream service specified by the value. In this example, the double-speed fast-transfer function 122 determines that the received RTSP PLAY command npt value contains a value below one decimal point, and is determined to be an action instruction of a non-general seekTo() function. The value 111 of the decimal point is analyzed to represent twice the fast turn, and then the video streaming instruction parsing module 210 is notified to perform the double fast transfer video data transmission operation, and the video playback control command is relayed to the mediation servo module 110. result. If the video stream instruction parsing module 210 parses the command content into a general standard RTSP command, the video data stream servo module 220 is notified to operate according to the command meaning specified by the standard RTSP command. If the RTSP command of the content of the following picture C is received, the video data stream servo module 220 will jump the content of the video and audio data being transmitted to the 5.2th second of the content of the video material.

Embodiment 2:

For example, the expansion of the iOS video playback control function and the use of the HTTP protocol, as shown in the architecture of FIG. 4 and the flow of FIG. 2, the media operator establishes a video streaming server 200 based on the HTTP protocol and sets the server. An IP address (such as 59.144.24.78) places an audio and video content media (data file media.mp4) in the storage medium of the video data stream server 200. And develop an iOS video playback service application (APP 100) to play media.mp4. The audio and video player module 120 in the APP1, the audio and video playback control command, the mediation servo module 110, and the video and audio streaming server 200 are connected by HTTP and are set in the native video player module 120. The video material source location URL is http://127.0.0.1/media.mp4 to direct its own video playback control command intermediary servo module 110. In addition to the start of playback function, the audio and video playback APP 100 implements two video playback control functions of the first five seconds 121 and twice the fast rotation 122 on the audio and video playback APP 100. The function of the first five seconds 121 can be directly used by the setCurrentPlaybackTime() API function provided by the iOS native video player. When the user presses the previous five seconds button, the video playback APP 100 program executes the following command mediaplayer.setCurrentPlaybackTime (parseInt(MediaPlayer.currentPlaybackTime/1000,10)+5); mediaplayer represents an iOS native video player object in the audio and video play APP 100. Firstly, the current movie play time mediaplayer.currentPlaybackTime() is converted into seconds and then added. Last 5 seconds, as a parameter passed to the setCurrentPlaybackTime function, to achieve the purpose of jumping forward five seconds of the movie time. The other two-time fast-forward 122 function is implemented in the manner mentioned in the present case, and is implemented in the following specific manner. When the user presses the double-fast forward 122 function button when the video content has started to be played, a standard HTTP command is sent by calling the setCurrentPlaybackTime() function (for example, executing setCurrentPlaybackTime(5200), where 5200 is randomly set. Value), and record in the video playback APP 100 that the user has pressed twice the fast-forward 122 key event. After the audio and video playback APP 100 executes the setCurrentPlaybackTime(5200) function, the native video player module

The content of the HTTP GET command contains a specified Range value, which is the first Byte position of the file to be converted into the data by the setCurrentPlaybackTime function. The instruction originally intended to support the HTTP protocol will be transmitted. The video content data jumps to the file location specified by the Range value, in this case, starting from the 3612672 byte (Byte). After the instruction is received by the video playback control command agent servo module 110, it is known from the previous record that the command event is triggered by the user pressing twice the fast-rotating 122 key, and the video streaming instruction parsing modification unit 111 changes the command. As shown in Figure E below:

In addition to forwarding the HTTP command to the video data stream server 200, the original video material source location URL IP is changed from the original 127.0.0.1 to the IP 59.144.24.78 of the video data stream server 200, and the Range value is also changed to FX2. FX2 is defined in advance and is hidden in the HTTP GET instruction to represent twice the instruction symbol or value. The principle of operation is to send an HTTP GET command by calling setCurrentPlaybackTime() function, modify the Range value, and place the extended instruction code in it. In addition, the extended instruction code can be placed in the HTTP GET instruction in other ways. As shown in the following figure F, an Action variable field is added to the HTTP GET instruction, and its value is FX2.

Similarly, other symbols or values can be defined to represent other functions (such as BX4 for reversing four times, CUP for up-switching channels, etc., system development) The user design defines different audio and video playback control functions. The hidden instruction code is hidden in the HTTP GET instruction. The video playback control command intermediary media module 110 forwards the modified HTTP GET command to the video stream server 200. After receiving the command, the video streaming server 200 parses the content of the command via the video streaming instruction parsing module 210. If the command is found to contain hidden command symbols or values, the video data stream servo module 220 is notified to perform the symbol or The video data stream service specified by the value. In this example, the double-speed fast-transfer function 122 determines that the received HTTP GET command includes the FX2 string, and then the video-audio data stream servo module 220 is notified to perform the double-speed fast-transfer video data transmission operation. And reply to the video playback control command agent servo module to process the result.

If the video streaming instruction parsing module 210 parses the command content into a general standard HTTP command (there is no extended instruction code), the video data stream servo module 220 is notified to operate according to the command specified by the standard HTTP command. If you receive the following HTTP GET command according to the content:

The video data stream servo module 220 jumps to the 3612672 byte of the video data file to transmit the data to the video playback control command mediation servo module 110, and then transmits the data to the mediation servo module 110 via the video playback control command. The native video player module 120 plays.

The detailed description of the present invention is intended to be illustrative of a preferred embodiment of the invention, and is not intended to limit the scope of the invention. The patent scope of this case.

To sum up, this case is not only innovative in terms of technical thinking, but also has many of the above-mentioned functions that are not in the traditional methods of the past. It has fully complied with the statutory invention patent requirements of novelty and progressiveness, and applied for it according to law.
