[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a media playing control method according to a first embodiment of the present invention includes the steps of:
s11: detecting whether an equipment access event exists or not, reading a file directory of access equipment triggering the equipment access event when the equipment access event is detected to acquire a file name and a file path of a target format file, and writing the acquired file name and file path of the target format file into a first database table;

Further, referring to fig. 2, step S13 of the present embodiment is, for example, a sub-step:
s131: reading data in the first database table to display a file information list when the first database table is detected to be modified; and
s133: and responding to the selection operation in the display file information list, and writing the target file name in the first database table and the file path corresponding to the target file name into the second database table.
In addition, referring to fig. 3, before step S15, the method for controlling media playing of the present embodiment may further include:
s14 a: reading the data in the second database table to display on a playing control interface; and
s14 b: and responding to the input operation on the playing control interface, and modifying the contents of the plurality of playing information items in the second database table.
Furthermore, the media playing control method of the embodiment may further include: and monitoring the record of the file playing control operation, and generating an automatic playing list according to the monitoring result.
In order to more clearly understand the steps S11, S13, S15, S14a and S14b and the sub-steps S131 and S133 of the media playback control method of the present embodiment, the following description is made with reference to fig. 4.
The present example provides a media playing control method for automatically identifying and well controlling a U disk based on an embedded operating system Linux platform, which can enable a user to appreciate media information in the U disk, record playing history of the U disk, freely select video files to form a playlist, realize real-time playing control, and improve user experience. The media playing control method of this example can be applied to products such as a video processor and a video player.
In light of the above, the media playing control method of this example is implemented as follows:
first, a database is created, and two database tables are built in, which are the distlist database table and the playlist database table shown in fig. 4. The system comprises a display database table, a playlist database table, a state control item (ctrl), a round robin item (loop), a priority item (priority), a play time item (playlist), and a click rate item (hit), wherein the display database table and the playlist database table are respectively provided with a plurality of data items, for example, the display database table contains a file name item (filename), a file path item (path), and the like, and the playlist database table contains a file name item (vod _ name), a file path item (path), and a plurality of play information items such as a state control item (ctrl), a round robin item (loop), a priority item (priority), a play time item (playlist), and a click rate item (hit). For example, the content of ctrl is 1 indicating that a video file is played, and 0 indicating that the playing of the video file is paused. And then, loading the distlist database table and the playlist database table into the embedded equipment, and then carrying out automatic U disk identification and file playing control.
The media playing control method of this example is executed in an embedded device and involves three processes, which are respectively: (a) access detection process, (b) play control process, and (c) play process; the specific description is as follows:
(a) access detection procedure
The access detection process detects whether a USB flash disk is inserted, and specifically, a hot plug event can be detected by using a Netlink mechanism. Netlink is a service facing to data packets, and a high-speed channel is built for a kernel and a user layer, which is the basis for udev realization. The working mode is asynchronous, the user layer program does not need to use technologies such as polling and the like to detect the hot plug event, and the monitoring of the hot plug event can be realized only by creating a socket descriptor and binding the descriptor to a receiving address. Wherein udev is a Linux kernel 2.6 series device manager, and the main function of the udev is to manage device nodes under/dev directories and also to take over devfs and hot plug.
Reading information one by one after detecting a USB flash disk insertion event, and searching and determining a mounting point of the USB flash disk; the method includes the steps of finding a mounting position of a U disk, then automatically reading a file directory of the U disk, sequentially detecting whether a directory name has a target format file such as a character of 'mp 4', certainly, the target format file is not limited to an mp4 video file, and can also be a video file or even a picture file in multiple file formats (such as avi, rmvb, mov, mp4 and the like), and writing information of the detected file, such as a file name and a file path, into a disklist database table.
In other words, the access detection process may detect a video file or a specified file, and automatically read the video file or a specified other file format in the usb disk. The user can set the format of the file to be read in advance, and then in the step of detecting reading, only the information of the format file set in advance is read. For example, it is set in advance to read only the video file information in mp4 format and add the video file information in mp4 format to the distylist database. The setting of the file format can be carried out through a human-computer interface, the automatic reading of the video file or the designation of the file refers to reading of the file name and the file path, so that the advantage that the video file in the U disk is not required to be directly downloaded to the local to save local resources is achieved, and the reading speed and the quick response speed of the system can be greatly improved by only reading the file name and the file path.
(b) Play control process
The playing control process may utilize a file monitoring tool, such as inotify-tools, to detect whether the distlist database table is modified, and when detecting that the distlist database table is modified due to the insertion of the usb disk and the writing of the information of the target format file, may transfer part or all of the information in the distlist database table to the playlist database table. The inotify-tools are a set of c development interface library functions provided for inotify file monitoring tools under Linux, and a series of command line tools are provided, and the tools can be used for monitoring events of a file system. inotify-tools are written in c, and are not dependent on others except for requiring the kernel to support inotify. inotify-tools provide two tools, inotifywait, which is used to monitor changes in files or directories, and inotifywatch, which is used to count the number of accesses to a file system.
In order to improve the software interface friendliness, the play control process may further read data in the distlist database table to display the file information list when detecting that the distlist database table is modified (corresponding to substep S131), so that a target file name may be selected from the displayed file information list through human-computer interaction, and then the target file name and a file path corresponding to the target file name in the distlist database table are written into the playlist database table according to a selection result (corresponding substep S133).
Furthermore, in order to flexibly set the playing control manner of the video file under the file path corresponding to the target file name, the playing control process may further read the data in the playlist database table to be displayed on the playing control interface (corresponding to step S14a), and modify the contents of the plurality of playing information items in the playlist database table in response to the input operation on the playing control interface (corresponding to step S14 b). For example, in the playing control interface, after a user clicks one or more file names and sets a loop mode, corresponding data items (e.g., ctrl, loop) in the playlist database table are modified; the loop mode here may be a single song loop, a list loop playing once, a list infinite loop, etc.
(c) Play process
The play control process may detect whether the playlist database table is modified by using a file monitoring tool such as inotify-tools, and when it is detected that the playlist database table is modified due to writing of a target file name and a file path corresponding thereto and/or modification of content of the play information item, the play control process may check data in the playlist database table, analyze content of the play information item in the playlist database table, call an interface to implement play/pause of the video file, and the like.
As can be seen from the above, the media playing control method of this example is completed by three processes. The access detection process detects the data of the U disk, and writes video file information into a distilist database table; the playing control process selects the contents of the distlist database table to store in the playlist database table to form a playing list and provide a human-computer interaction playing control interface; and the playing process detects the change of the playlist database table, analyzes the content of the playing information item, and completes the playing control function (such as playing, pausing, fast forwarding and the like). In this example, the inotify-tools are used to detect the change of the database table, so as to realize the transmission of signals between the three processes.
In light of the above, the media playing control method of this example may further use a player monitoring module to monitor the record of the file playing control operation, including the information of the requested/played file path, frequency, duration, time period, etc., and automatically sort and generate the automatic playlist according to the above information. For example, a play order list is generated according to the time slot and frequency of the requested video file, and the user can know the video files which are requested/played at each hot time slot according to the list and make reference to the requested video files. And when the user does not carry out the on-demand operation, the player realizes automatic playing according to the automatic playing list.
In summary, the present embodiment can automatically detect the insertion of the usb disk, store the video file information in the usb disk in the database table, and control the video playing by the playing software through the interactive database table; simple operation and strong practicability. Furthermore, the user can select the filter video format according to the preference, and freely check out the information of the video files written in the database table, for example, if the mp4 format is selected, only the video files in the mp4 format are checked out when the U disk is checked out. In addition, the user can control the video file to play according to different modes, namely, the playing mode of the video is set on the playing control interface: single song circulation, list circulation playing once, list infinite circulation and the like; as a video processing device, in the scene of outdoor video playing, a play list, a list circulation mode and the like are set, so that automatic video playing can be realized, and the video processing device has strong practicability in practical application.
It should be noted that the above automatic identification of the usb disk and video playing may also be applied to automatic identification of other access devices, such as automatic identification of optical disk, and automatic identification of wireless devices such as bluetooth. For example, for a bluetooth device, whether the bluetooth device is connected is detected, and when the bluetooth device is detected to be connected, a video file or other specified file formats in the bluetooth device are automatically read, and the read video file is added to a database table in the embedded device.
