With the rapid development of the internet of things technology and the wide popularization of smart homes, the processing requirements of users on the streaming media files of the smart home devices are higher and higher. For example, in the environment of smart homes, network music or network video is played through a control panel on a wall surface, so that audiovisual enjoyment is brought to users anytime and anywhere. However, in the existing smart home environment, when a single smart device plays online music, due to the fact that the network speed is slow or the data volume of streaming media files such as songs is large, the streaming media files such as songs played online may be not cached in time, and this situation generally causes the problems of playing being blocked and unsmooth. In the prior art, in order to solve the above technical problem, a scheme is proposed in which downloading threads are increased based on the above single device, so as to improve the progress of caching. However, the solution does not consider that the smart home devices such as the control panel and the like need to bear the execution and scheduling of the multifunctional task, if the downloading threads are singly added for a single device, other function implementation of the device may be affected, the phenomena of unsmooth locking and unsmooth flowing are further emphasized, and the user experience is poor. Therefore, the problems of unsmooth and unsmooth operation in the function implementation process of the intelligent home device brought to the user are avoided, meanwhile, a more smooth streaming media file processing scheme is provided for the user, and the use experience of the user is enhanced.
Therefore, the inventor provides an intelligent processing method, a control panel and a computer-readable storage medium for a streaming media file, which are provided by an embodiment of the present application, so that an intelligent home device can provide a smoother streaming media file processing experience for a user, and in this embodiment, an intelligent processing scheme for a streaming media file is provided, in which a streaming media file playing device broadcasts a request for assisting in caching a target streaming media file to a local area network by recognizing that a file cache state when the streaming media file playing device plays the target streaming media file meets a preset first condition, so that the streaming media file caching device receiving the request in the local area network feeds back network connection state information between the streaming media file caching device and a network server storing the target streaming media file to the streaming media file playing device; then, when the streaming media file playing device judges that the network connection state information meets a preset second condition, the streaming media file playing device sends an instruction for requesting the network server to cache the target streaming media file to the streaming media file caching device, so that the streaming media file caching device requests the network server to cache the target streaming media file after receiving the instruction, and sends the cached target streaming media file to the streaming media file playing device after the streaming media file caching device caches the target streaming media file, thereby providing a smoother streaming media file processing scheme for a user and simultaneously ensuring that the intelligent home device cannot have the problems of blocking and unsmooth flow in the implementation process of executing other functions.
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating an intelligent processing method for a streaming media file according to an embodiment of the present application. The intelligent processing scheme for streaming media files provided by this embodiment is not only applicable to an intelligent home environment through a control panel for controlling intelligent home devices, but also applicable to an intelligent home environment, and any networking device in the same home network range can determine a corresponding intelligent processing scheme according to different processing devices for streaming media files, so that the processing requirements for streaming media files of multiple devices in an intelligent home environment can be met, and this embodiment provides an intelligent processing method for streaming media files, which is applied to streaming media file playing devices, and the method includes:
s1, when the file caching status of the streaming media file playing device during playing the target streaming media file meets a first preset condition, the streaming media file playing device broadcasts a request for assisting in caching the target streaming media file to a local area network, so that the streaming media file caching device receiving the request in the local area network feeds back the network connection status information between the streaming media file caching device and a network server storing the target streaming media file to the streaming media file playing device.
In this embodiment, after receiving a playing instruction of a target streaming media file from a user, a streaming media file playing device connects a network server where the target streaming media file is stored to a network to which the streaming media file playing device is currently connected; inquiring whether the configuration option of the current streaming media file playing device is playing while caching, if so, when the streaming media file playing device is successfully connected with the network server through the currently accessed network, starting to cache the cache data of the streaming media file returned by the network server through the currently accessed network by the streaming media file playing device, and starting to play the streaming media file synchronously or after delaying preset time. In this embodiment, a file cache state of the streaming media file playing device for caching the cache data of the streaming media file is monitored in real time, and meanwhile, a first condition in the monitoring process is determined, where the first condition is that a cache progress of the streaming media file playing device for caching the cache data of the streaming media file cannot meet a playing progress of the streaming media file playing device for playing the streaming media file. Specifically, when the file caching state of the streaming media file playing device when playing the target streaming media file is that the caching progress of the streaming media file playing device for caching the caching data of the streaming media file cannot meet the playing progress of the streaming media file playing device for playing the streaming media file, the streaming media file playing device broadcasts a request for assisting in caching the target streaming media file to a local area network, wherein the local area network where the streaming media file playing device is located can be formed according to all networking devices in the same intelligent home environment. In this embodiment, when the buffering progress of the streaming media file playing device for buffering the buffering data of the streaming media file cannot meet the playing progress of the streaming media file playing device for playing the streaming media file, the request for assisting in buffering the target streaming media file is broadcast to the local area network where the streaming media file playing device is located, so that other networking devices of the local area network can assist the streaming media file playing device in buffering the buffering data of the streaming media file. In this embodiment, in order to determine whether other networking devices of the local area network can assist the streaming media file playing device to cache the cache data of the streaming media file, network connection state information of the other networking devices of the local area network and the network server storing the target streaming media file is first determined, then, other networking devices in the network connection state information that can meet the auxiliary cache requirement are used as the streaming media file caching device of this embodiment, and the network connection state information of such streaming media file caching device is fed back to the streaming media file playing device, so that the streaming media file playing device can perform subsequent cache task allocation of the remaining cache data as needed.
S2, when the streaming media file playing device determines that the network connection status information satisfies the second predetermined condition, the streaming media file playing device sends an instruction to the streaming media file caching device to request the network server to cache the target streaming media file, so that the streaming media file caching device requests the network server to cache the target streaming media file after receiving the instruction, and sends the cached target streaming media file to the streaming media file playing device after the streaming media file caching device caches the target streaming media file.
In this embodiment, in order to facilitate the streaming media file playing device to perform subsequent cache task allocation of the remaining cache data as required, first, a second condition is set for network connection status information returned by the streaming media file caching device, where the second condition is that the streaming media file caching device can complete the cache task allocated to the streaming media file as required, and specifically, the second condition includes but is not limited to a connection status with a network server, a transmission delay with the network server, and a transmission bandwidth with the network server. It can be understood that, in order to obtain the cache data that can satisfy the requirement that the streaming media file playing device caches the streaming media file, in this embodiment, the streaming media file caching device is screened according to the set second condition, so as to determine to obtain the streaming media file caching devices that have the appropriate number and meet the caching requirement. In this embodiment, after determining the streaming media file caching device meeting the preset second condition, the streaming media file playing device sends an instruction to the streaming media file caching device to request the network server to cache the target streaming media file, so that the streaming media file caching device requests the network server to cache the target streaming media file after receiving the instruction. Meanwhile, in order to solve the problem that the buffering progress of the single streaming media file playing device is delayed from the playing progress, in this embodiment, after the streaming media file buffering device buffers the target streaming media file, the buffered target streaming media file is timely sent to the streaming media file playing device, so that the buffering progress of the streaming media file playing device is indirectly prior to the playing progress, and the requirement that the streaming media file playing device plays the streaming media file in real time is met.
The method has the advantages that when the file cache state of the streaming media file playing device during playing of the target streaming media file meets the preset first condition, the streaming media file playing device broadcasts a request for assisting in caching the target streaming media file to the local area network, so that the streaming media file cache device receiving the request in the local area network feeds back the network connection state information of the streaming media file cache device and a network server for storing the target streaming media file to the streaming media file playing device; then, when the streaming media file playing device judges that the network connection state information meets a preset second condition, the streaming media file playing device sends an instruction for requesting the network server to cache the target streaming media file to the streaming media file caching device, so that the streaming media file caching device requests the network server to cache the target streaming media file after receiving the instruction, and sends the cached target streaming media file to the streaming media file playing device after the streaming media file caching device caches the target streaming media file, thereby providing a smoother streaming media file processing scheme for a user and simultaneously ensuring that the intelligent home device cannot have the problems of blocking and unsmooth flow in the implementation process of executing other functions.
Example two
Based on the foregoing embodiment, in this embodiment, in order to further determine whether the cache progress of the streaming media file playing device for caching the cache data of the streaming media file can meet the playing progress of the streaming media file playing device for playing the streaming media file, the first condition is set that the playing progress of the streaming media file playing device for playing the target streaming media file is faster than the cache progress. Specifically, it is determined that the playing progress of the target streaming media file is later than the caching progress, for example, when the playing progress is 1 minute and 15 seconds, at this time, the caching progress is 1 minute and 18 seconds, at this time, it is determined that the caching progress of the cached data of the streaming media file can meet the playing progress of the streaming media file playing device for playing the streaming media file; if the playing progress is 1 minute and 15 seconds, at this time, the caching progress is 1 minute and 14 seconds, or 1 minute and 15 seconds, and at this time, it is determined that the caching progress of the cached data of the streaming media file cannot meet the playing progress of the streaming media file playing device for playing the streaming media file. In another setting scheme of the first condition, it is determined whether a time that a playing progress of the target streaming media file is later than a buffering progress is greater than a preset time. For example, the preset time is 2 seconds, if the time that the playing progress is later than the caching progress is 3 seconds, that is, when the playing progress is 1 minute 15 seconds, at this time, the caching progress is 1 minute 18 seconds, at this time, it is determined that the caching progress of the cached data of the streaming media file can meet the playing progress of the streaming media file playing device for playing the streaming media file; if the time that the playing progress is later than the caching progress is 1 second, that is, when the playing progress is 1 minute 15 seconds, at this time, the caching progress is 1 minute 16 seconds, and at this time, it is determined that the caching progress of the cached data of the streaming media file cannot meet the playing progress of the streaming media file played by the streaming media file playing device. In still another setting scheme of the first condition, it is determined whether a time at which a play progress is later than a buffering progress when the target streaming media file is played is in a decreasing state. For example, the amplitude of the time in the decreasing state is 2 seconds, if at the first time, the time that the playing progress is later than the buffering progress is 10 seconds, that is, when the playing progress is 1 minute 15 seconds, at this time, the buffering progress is 1 minute 25 seconds, at the second time, the time that the playing progress is later than the buffering progress is 7 seconds, that is, when the playing progress is 1 minute 15 seconds, at this time, the buffering progress is 1 minute 22 seconds, at the third time, the time that the playing progress is later than the buffering progress is 4 seconds, that is, when the playing progress is 1 minute 15 seconds, at this time, the buffering progress is 1 minute 19 seconds, at this time, it is determined that the buffering progress of the buffered data of the streaming media file cannot meet the playing progress of the streaming media file playing device.
Based on the foregoing embodiment, in this embodiment, in order to further determine that the streaming media file playing device can perform subsequent cache task allocation of the remaining cache data as required, and determine a qualified and appropriate streaming media file cache device, the network connection state information is set as the transmission link on-off state information and the transmission bandwidth information between the streaming media file cache device and the network server storing the target streaming media file. Specifically, the information on the on-off state of the transmission link between the network servers of the target streaming media file includes: first, whether a transport connection can be successfully established with the network server, second, including a transport delay when the transport connection is established with the network server, and third, including transport bandwidth information when the transport connection is established with the network server. Optionally, in this embodiment, a lowest bandwidth value of the transmission bandwidth is set, and or a highest latency value of the transmission delay when the transmission connection is established with the network server is set, so that, in the streaming media file caching device that is determined to be able to successfully establish the transmission connection with the network server, the streaming media file caching device whose transmission delay when the transmission connection is established with the network server is greater than the highest latency value, and or the streaming media file caching device whose transmission bandwidth when the transmission connection is established with the network server is smaller than the lowest bandwidth value is further removed, thereby further improving the efficiency of allocation and execution of subsequent caching tasks, and avoiding waste of processing resources.
Based on the foregoing embodiment, in this embodiment, in order to further determine that the streaming media file caching device can perform a subsequent caching task of remaining cached data as needed, a second condition of this embodiment is that the transmission link is successfully established, and the transmission bandwidth is greater than a preset first bandwidth threshold, where the first bandwidth threshold may be set according to configuration of the system, and may also be determined according to a current network bandwidth of the streaming media file device itself, for example, one half of the current network bandwidth of the streaming media file device itself is used as the first bandwidth threshold of this embodiment, so as to improve flexibility of selection of the streaming media file caching device in this scheme.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating an intelligent processing method for a streaming media file according to another embodiment of the present application. In this embodiment, before the step of sending, by the streaming media file playing device, an instruction to the streaming media file caching device to request the network server to cache the target streaming media file, the method includes the following steps.
S11, determining the current buffer progress of the streaming media file playing device when playing the target streaming media file.
In this embodiment, the caching progress of a streaming media file being played is determined, so that data to be cached is subsequently distributed to streaming media file playing equipment and streaming media file caching equipment to jointly execute a caching task; optionally, determining a caching progress of a streaming media file being played, so that data to be cached is subsequently distributed to one or more streaming media file caching devices to execute a caching task, and the streaming media file playing device does not execute the subsequent caching task any more; optionally, the caching progress of a group of streaming media files being played is determined, so that data to be cached of a currently played file in the group of streaming media files is subsequently allocated to the streaming media file playing device to execute the caching task, and data to be cached of a currently unplayed file in the group of streaming media files is allocated to the streaming media file caching device to execute the caching task.
And S12, determining the data to be cached of the target streaming media file according to the current caching progress. Similarly, as described in the above example, the data to be cached of the target streaming media file is determined according to the actual streaming media file caching requirement. For example, determining the caching progress of a streaming media file being played, and distributing data to be cached to streaming media file playing equipment and streaming media file caching equipment to jointly execute a caching task; optionally, determining a caching progress of a streaming media file being played, allocating data to be cached to one or more streaming media file caching devices to execute a caching task, and the streaming media file playing device does not execute subsequent caching tasks any more; optionally, determining a caching progress of a group of streaming media files being played, allocating data to be cached of a currently played file in the group of streaming media files to a streaming media file playing device to execute a caching task, and allocating data to be cached of a currently unplayed file in the group of streaming media files to the streaming media file caching device to execute the caching task; optionally, the caching progress of a group of streaming media files being played is determined, data to be cached of a currently played file in the group of streaming media files is allocated to a streaming media file caching device to execute a caching task, and data to be cached of a currently unplayed file in the group of streaming media files is sequentially allocated to a corresponding number of streaming media file caching devices according to the number of files, so that one streaming media file caching device executes the caching task of one streaming media file.
Referring to fig. 3, fig. 3 is a flowchart illustrating an intelligent processing method for a streaming media file according to another embodiment of the present application. In this embodiment, the step of sending, by the streaming media file playing device, an instruction to the streaming media file caching device to request the network server to cache the target streaming media file includes the following steps.
S21, determining a first transmission bandwidth when the streaming media file playing device plays the target streaming media file, and determining a second transmission bandwidth when the streaming media file caching device caches the target streaming media file. When the streaming media file playing device and the streaming media file caching device jointly execute the caching task of the data to be cached, in order to facilitate reasonable division of the caching task, in this embodiment, a division ratio of the caching task is determined according to a bandwidth ratio, that is, a first transmission bandwidth when the streaming media file playing device plays the target streaming media file and a second transmission bandwidth when the streaming media file caching device caches the target streaming media file are determined.
S22, dividing the data to be cached into first data to be cached and second data to be cached according to the proportional relation between the first transmission bandwidth and the second transmission bandwidth, respectively serving as a caching task of the streaming media file playing device and a caching task of the streaming media file caching device, and sending the caching task of the streaming media file caching device to the streaming media file caching device. Specifically, for example, in an intelligent home environment, when a current streaming media file playing device a determines that auxiliary caching is required for other streaming media file caching devices, if it is determined that the streaming media file caching device B is a device capable of auxiliary caching, it is determined that the network bandwidth of the streaming media file caching device B is determined, and if it is determined that the network bandwidth of the streaming media file playing device a is greater than the bandwidth of the streaming media file caching device B, data to be cached is sequentially allocated according to the device a and the device B from large to small. Further, if it is detected that the bandwidth ratio of the device a to the device B is 4: 3, (device a) 4: and (equipment B)3, allocating the data to be buffered.
In this embodiment, optionally, if there are a plurality of streaming media file caching devices, the second data to be cached is divided according to a proportional relationship of the second transmission bandwidths of the streaming media file caching devices, and the divided second data to be cached is respectively used as the caching tasks of the streaming media file caching devices. Specifically, for example, in an intelligent home environment, when the current streaming media file playing device a determines that auxiliary caching is required by other streaming media file caching devices, if it is determined that there are 3 auxiliary buffering devices in the streaming media file buffering device B, the streaming media file buffering device C and the streaming media file buffering device D, determining the network bandwidth of the streaming media file caching device B, the streaming media file caching device C and the streaming media file caching device D, if the network bandwidth of the streaming media file caching device B is determined to be larger than that of the streaming media file caching device C and the network bandwidth of the streaming media file caching device C is determined to be larger than that of the streaming media file caching device D, the network bandwidth of the streaming media file playing device a is larger than that of all the streaming media file caching devices, then the data to be cached from large to small are sequentially distributed according to the sequence of the device A, the device B, the device C and the device D. Further, if it is detected that the bandwidth ratios of the device a, the device B, the device C, and the device D are 4: 3: 2: 1, (device a) 4: (apparatus B) 3: (device C) 2: the proportion of (device D)1 performs the allocation of the data to be buffered.
Referring to fig. 4, fig. 4 is a flowchart illustrating an intelligent processing method for a streaming media file according to another embodiment of the present application. In this embodiment, after the step of sending, by the streaming media file playing device, an instruction to the streaming media file caching device to request the network server to cache the target streaming media file, the method includes the following steps.
S31, determining a third transmission bandwidth of each streaming media file caching device and each streaming media file playing device.
In this embodiment, when the streaming media file playing device performs cache task allocation, if the assisted cache progress still cannot precede the playing progress, the cache tasks of the streaming media file caching devices are allocated reasonably again according to different third transmission bandwidths by determining the third transmission bandwidths of the streaming media file caching devices and the streaming media file playing device.
S32, increasing the caching task of the streaming media file caching device with the third transmission bandwidth larger than the second bandwidth threshold value, and synchronously decreasing the caching task of the streaming media file caching device with the third transmission bandwidth smaller than the second bandwidth threshold value.
In this embodiment, specifically, all the caching tasks of the streaming media file caching device with the third transmission bandwidth larger than the second bandwidth threshold are added, and according to the proportion exceeding the second bandwidth threshold, the proportion of the added caching tasks of the streaming media file caching device is determined, and at the same time, all the caching tasks of the streaming media file caching device with the third transmission bandwidth smaller than the second bandwidth threshold are reduced, and according to the proportion smaller than the second bandwidth threshold, the proportion of the reduced caching tasks of the streaming media file caching device is determined. Optionally, another implementation of this embodiment is to determine a third transmission bandwidth of each of the streaming media file caching device and the streaming media file playing device, meanwhile, a fourth bandwidth threshold value which is smaller than the second bandwidth threshold value is set, at the moment, all caching tasks of the streaming media file caching equipment of which the third transmission bandwidth is larger than the second bandwidth threshold value are added, and determining the increasing proportion of the caching task of the streaming media file caching equipment according to the proportion exceeding the second bandwidth threshold, meanwhile, reducing all caching tasks of the streaming media file caching device with the third transmission bandwidth smaller than the second bandwidth threshold and larger than the fourth bandwidth threshold, canceling all caching tasks of the streaming media file caching device with the third transmission bandwidth smaller than the fourth bandwidth threshold, and determining the reduction ratio of the caching tasks of the residual streaming media file caching equipment according to the ratio smaller than the second bandwidth threshold value. Therefore, the flexibility of each streaming media file caching device in the process of allocating the caching task is further improved, the streaming media file playing device can perform adaptive adjustment on the caching task allocation in time in the face of different local area network environments, and the application universality, timeliness and effectiveness of the intelligent processing scheme of the streaming media file are improved.
