The specific implementation of the embodiments of the present application will be further described in detail below with reference to the accompanying drawings (the same reference numerals in several drawings represent the same elements) and embodiments. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

Those skilled in the art can understand that terms such as “first” and “second” in the embodiments of the present application are only used to distinguish different steps, devices, or modules, etc., and they do not represent any specific technical meaning, nor mean between them. Inevitable logical order.

Example one

Referring to FIG. 1, there is shown a flowchart of steps in a method for transmitting and playing a file according to the first embodiment of the present application.

It is worth noting that steps S 101 to S 103 described in this application do not represent the order of execution.

The file transmission and playback method in this embodiment includes the following steps:

Step S101: Determine whether the current network environment of the near field communication reaches a preset threshold according to the current file transmission speed.

Specifically, the network environment described in the embodiment of the present application may be obtained by the currently received file transmission speed, and the stability and bandwidth of the network may be determined by whether the file transmission speed is substantially the same and the speed of the transmission speed.

The preset thresholds described in the embodiments of the present application are set by those skilled in the art as needed. The preset thresholds described in the embodiments of the present application can be adjusted as needed.

Step S102: If it is reached, then cache segment data in the video data that meets the playback requirements, and read and play the cached segment data.

If the network environment described in the embodiment of the present application reaches a preset threshold, it meets the requirements for file transmission and simultaneous playback by means of caching, and then implements segmented storage and reading and playback of data by means of caching.

In a specific implementation of this application, segmented data in video data that meets playback requirements is cached, so that the cached segmented data can be read and played during the file transmission process.

In the embodiment of the present application, the video data that meets the playback requirements is segmented data that is segmented by the video data, which is data that can directly read and play. Step S103: if not, save the segment data in the video data that meets the playback requirements to a local agent, and read and play the segment data through the local agent.

If the network environment described in the embodiment of the present application does not reach the preset threshold, if the file transmission and simultaneous playback are continued in the cache mode, the data discontinuity will be slower than the player playback speed, and there will be stuttering, frame dropping, etc. Experience problems. Therefore, in the embodiment of the present application, a local proxy is used to implement data segmented storage and read and play.

From this, it can be known that the embodiment of the present application determines whether the current network environment of near field communication has reached a preset threshold according to the current file transfer speed. If the current network environment reaches a preset threshold, the cache is used for segmented data storage and reading and playback. Segmented storage and read playback. The embodiments of the present application can adopt different data access modes according to the network environment, so that the transmitted files can be played while the files are being transmitted. In the embodiment of the present application, the user does not need to wait for the video file transmission to be completed before playing, which improves the user experience in the near-field transmission process.

The method for file transmission and playback in this embodiment may be performed by any appropriate device capable of file transmission and playback, including but not limited to: various device terminals or servers, including but not limited to PCs, tablets, and mobile phones Terminal, etc.

Example two

This embodiment includes the above steps S101 to S103. Referring to Figure 2, the method further comprising the step S lOO _o

Step S100: Process the original video file data so that the header file information of the original video file data is located at the head of the video file.

The header file information of the video file defines information such as the video playback format, frame information, and rate. These information must be obtained first during playback. If the header file information is placed in the middle or the tail of the video file, partial playback cannot be performed according to the segmented data of the video file, and the playback can only be performed after the video file has been completely transferred.

Therefore, in near field communication, since the video provider is also a terminal device, the video file data that does not meet the segmentation requirements is repackaged in the terminal device, the header file information is moved to the head of the video file, and then sent to another A terminal device.

From this, it can be known that the embodiment of the present application determines whether the current network environment of near field communication has reached a preset threshold according to the current file transfer speed. If the current network environment reaches a preset threshold, the cache is used for segmented data storage and reading and playback. Segmented storage and read playback. This The embodiment of the application can adopt different data access modes according to the network environment, so that the transmitted file can be played while the file is being transmitted. In the embodiment of the present application, the user does not need to wait for the video file to be transmitted before playing, which improves the user experience during the near-field transmission.

Example three

This embodiment includes the above steps S101 to S103. Referring to FIG. 3, the step S101 includes:

Step S 101 1. Determine whether the stability of the current network environment of the near field communication reaches the stability threshold according to the current file transfer speed.

Specifically, the embodiment of the present application determines whether the stability of the current network environment reaches the stability threshold according to whether the change value of the current file transmission speed reaches the stability threshold.

Step S 1012: Determine whether the transmission speed of the current network environment of the near field communication reaches the speed threshold according to the current file transmission speed.

Specifically, the embodiment of the present application determines whether the speed of the current network environment reaches the speed threshold according to whether the current file transmission speed reaches the speed threshold.

Therefore, the embodiment of the present application can simply judge the current network environment of near field communication based on the current file transmission speed, so as to determine whether the network connection satisfies the method of implementing file playback during file transmission in a cached manner.

Specifically, when the network environment connection stability and the transmission speed reach a preset threshold, there is no need to establish a local proxy server between the client and the server, and only a cache area with an appropriate capacity is needed to cache the segmented data. It will be written into a local file, and the contents of the buffer area will be directly returned to the player for playback, so that the video file can be played while being transmitted.

The cache area described in the embodiment of the present application is implemented by using the least recently used algorithm cache technology. Least Recently Used Cache (LruCache, Least Recently Used Cache) The core idea is that when the cache is full, those cache objects that are least recently used are preferentially eliminated. LmCache is a generic class. It uses a LinkedHashMap internally to store external cache objects in a strong reference manner. It provides get and put methods to complete cache acquisition and addition.

Therefore, in the embodiment of the present application, the least recently used algorithm caching technology can be used to realize the transmission of video files in near field transmission and play at the same time. The implementation is simple and greatly improves the user experience.
