In this way, the user can review the content by dragging the progress bar of the live video.
Currently, a live broadcast platform may accelerate a transmission process of a live broadcast video through a Content Delivery Network (CDN). Therefore, the playing end can acquire the live video pushed by the live client through the nearby edge node. When the time shift processing of the live video is performed, the recording and broadcasting work can be performed by the edge node. Specifically, when receiving a live video, the edge node may store the received live video. In this way, when the subsequent playing end initiates a time shift request to the edge node, the edge node can provide the corresponding review content to the subsequent playing end.
However, in the processing method in the prior art, on one hand, the edge node needs to provide live videos to each playing end, and also needs to perform recording and playing processing on the live videos, and also needs to process a time shift request of the playing end, and provide corresponding review content to each playing end. Thus, the edge node will keep a high load continuously, which will not only affect the push streaming efficiency of the live video, but also affect the processing efficiency of the time shift request.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Example one
The application provides a live video processing method which can be applied to a video processing device. The video processing apparatus may be disposed on an edge node in the CDN. Referring to fig. 1, the method may include the following steps.
S11: and when the live broadcast starts, acquiring a live broadcast video.
In this embodiment, the live broadcast client may push the live broadcast video to each playing terminal through the CDN. The live broadcast client can be a client used by a main broadcast, and the playing end can be a client used by a user watching a live broadcast video. In this embodiment, an independent video processing device may be provided, and the video processing device may also establish a connection with the live client through the CDN. When the live client starts to push live video, in order to ensure that the video processing device can record complete video content, the live client can send a live start prompt to the video processing device. After receiving the live broadcast starting prompt, the video processing device can respond to the live broadcast starting prompt and acquire the live broadcast video of the live broadcast client through the edge node of the content distribution network.
S13: dividing the live video into a plurality of video slices according to a specified time interval, and establishing index files of the video slices.
In this embodiment, after receiving the live video, the video processing apparatus may divide the live video into a plurality of video slices, so that the subsequent playing end may be positioned to the corresponding video slice when dragging the progress bar to select the review content. In particular, the division of the video slices may be performed at specified time intervals. The specified time interval may be a predetermined length of time. Referring to fig. 2, for example, the specified time interval may be 5 seconds, and during the playing of the live video, the video slice may be divided every 5 seconds, and the duration of the obtained video slice may be 5 seconds. Of course, the specified time interval may be changed according to actual requirements, and the shorter the specified time interval is, the more accurate the review content obtained by final positioning may be.
In the present embodiment, when video slices are divided, index information of each video slice can be set every time a video slice is obtained, and the set index information can be written in an index file. Wherein, the index information may include a slice identifier and a start playing time of the video slice. The slice identifier may be a file name set for the video slice. For example, the slice identification of one video slice may be "abc. The start playing time may be a corresponding start playing time of the video slice in the live video. For example, if the video slice shows the content from the 10 th second to the 15 th second of the live video, the starting playing time of the video slice may be the 10 th second.
In this embodiment, each time a current video slice is obtained by dividing, it may be determined whether an index file is currently created. Wherein, the index file can be fixedly stored under the appointed path of the video processing device. In this way, each time a current video slice is obtained by dividing, whether an index file exists under the specified path can be read. If not, the index file is not established currently. At this time, an index file may be newly created under the specified path, and index information of the current video slice may be written in the newly created index file. And if the index file is already established under the specified path, the index information of the current video slice can be added in the established index file.
In this embodiment, the video processing apparatus may slice the Live video using an HTTP Live Streaming (HTTP Live Streaming) protocol to obtain a TS slice conforming to a TS (Transport Stream) encapsulation format, and the index file established for the TS slice may be an m3u8 file.
S15: and uploading the plurality of video slices and the index file obtained by division to a cloud storage system.
In this embodiment, the video slices obtained by dividing by the video processing apparatus and the created index file may be stored in a cloud storage system in a unified manner. When a video slice is stored, the index information of the video slice already sets a slice identifier for the video slice, and then the video slice can be stored in the cloud storage system according to the slice identifier defined by the index information. For example, after a certain video slice is divided, the file name of the video slice is set to "abc.ts" in the corresponding index information, and then the video slice can be stored by using the file name of "abc.ts" when the video slice is stored in the cloud storage system.
In this embodiment, when the video slice is stored in the cloud storage system, incremental storage may be performed, and the newly divided video slice may be written into the cloud storage system each time. For example, a storage space may be set in the cloud storage system, the divided video slices may be sequentially written in the division order of the video slices, and the newly divided video slice may be located after the previously divided video slice. When the index file is stored, the index file can be stored in an overlaying manner, and the index file stored in the cloud storage system can be overlaid with a new index file every time. In the cloud storage system, the video slices and the index files can be stored separately due to different storage modes of the video slices and the index files. Specifically, the index file may be stored in a first storage device of a cloud storage system, and the plurality of video slices may be stored in a second storage device of the cloud storage system. Because the index file needs to be stored in a covering manner continuously, the reading and writing speed and performance of the first storage device corresponding to the index file can be relatively high, and therefore the reading and writing speed of the first storage device can be higher than that of the second storage device. In an actual application scenario, the first storage device may be a solid state disk with a smaller storage space but a faster read-write speed; and the second storage device may be a mechanical hard disk with a large storage space but a slow read-write speed. In this way, when storing video slices and index files, the video slices can be sequentially written into the second storage device, and when storing the index files into the first storage device, the index files already stored in the first storage device can be overwritten with the current index files.
In this way, through the processing of the video processing device, the live video starting to be live can be stored in the cloud storage system in a slicing mode, and the time shifting processing of the live video can be provided by the cloud storage system subsequently.
Example two
Referring to fig. 3, the present application further provides a video processing apparatus, which includes a memory and a processor, wherein the memory stores a computer program, and the computer program, when executed by the processor, implements the following steps:
s11: when live broadcasting starts, acquiring a live broadcasting video;
s13: dividing the live video into a plurality of video slices according to a specified time interval, and establishing index files of the video slices;
s15: uploading the plurality of video slices and the index file obtained by division to a cloud storage system
The video processing apparatus provided in this embodiment may be explained in comparison with the manner of the live video processing method, and may achieve the technical effects of the method embodiments, which are not described herein again.
EXAMPLE III
The application also provides a time shifting method of the live video, and the method can be applied to a cloud storage system. The cloud storage system can store a plurality of video slices of live videos and index files of the video slices, wherein the video slices and the index files can be uploaded by a video processing device. As can be seen from the above embodiments, the index file may be stored in a first storage device, the plurality of video slices may be stored in a second storage device, and the read-write speed of the first storage device may be greater than the read-write speed of the second storage device. When the video processing device uploads the plurality of video slices and the index file, the cloud storage system may adopt an incremental storage mode for the video slices and an overlay storage mode for the index file. Specifically, the cloud storage system may sequentially write each video slice into the second storage device, and may overwrite an index file already stored in the first storage device with a currently received index file.
Referring to fig. 4, the time shifting method of the live video may include the following steps.
S21: and receiving an index file acquisition request sent by a playing end.
In this embodiment, when a user needs to watch the content that the live video has been played, the progress bar of the live video may be dragged to a certain time node, and the content that has been played may be watched from the time node. When the progress bar of the live video is dragged to the current time node, the playing end may send a time shift request to the cloud storage system. Specifically, the time shift request may be an index file acquisition request. In this embodiment, the index file acquisition request may include an identifier of the live video, so that when the cloud storage system acquires the index file acquisition request, it can be known to which live video the request is initiated.
S23: and responding to the index file acquisition request, reading the index file from the first storage device, and feeding back the index file to the playing end, so that the playing end determines the slice identifier adaptive to the current time shifting time node according to the index file.
In this embodiment, after receiving the index file acquisition request, the cloud storage system may extract the identifier of the live video from the index file acquisition request. And then acquiring a corresponding index file from the cloud storage system based on the identification of the live video.
Specifically, the cloud storage system may preferentially detect whether an index file adapted to the index file acquisition request exists in the cache. The index file adapted to the index file obtaining request may indicate that the identifier of the index file is consistent with the identifier carried in the index file obtaining request. If the index file exists, the cloud storage system can directly provide the index file in the cache to the playing end. If the index file does not exist, the cloud storage system may read the index file from the first storage device, and provide the read index file to the playing terminal.
In an embodiment, in order to improve reliability of the index file, the index file in the first storage device may be written into the second storage device in a time-delay synchronization manner according to a specified time period, and when a current index file is written into the second storage device, the index file already stored in the second storage device is overwritten by the current index file. The specified time period can be adjusted according to actual requirements. In this way, when the index file cannot be read in the first storage device, the cloud storage system may read the index file from the second storage device.
In this embodiment, after the cloud storage system provides the index file to the playing end, the playing end may determine the video slice that needs to be currently viewed. Specifically, the index file may include index information of each video slice, where the index information includes a slice identifier and a start playing time of each video slice. The slice identifier may be a file name of the video slice, and the start playing time may be a start playing time of the video slice in the live video. In this way, the playing end may determine the slice identifier adapted to the current time shift node according to the index file. Specifically, the playing end may query, in the index file, a target start playing time closest to the current time shift time node, and use a slice identifier corresponding to the target start playing time as a slice identifier adapted to the current time shift time node. For example, the user drags the progress bar of the live video to a time node of 5 minutes and 13 seconds, and at this time, the index file fed back by the cloud storage system may be queried to find the initial playing time of 5 minutes and 15 seconds, which is closest to the time node, in the index file. And the file name of the video slice corresponding to the starting playing time of 5 minutes and 15 seconds can be "abc.ts", so that the video slice of "abc.ts" can be the target video slice which is matched with the time node currently dragged by the user.
S25: and receiving a video slice acquisition request sent by the playing end, wherein the video slice acquisition request comprises the determined slice identifier.
In this embodiment, after the playing end determines the slice identifier adapted to the current time node, the time shift request may be sent to the cloud storage system again. At this time, the time shift request may be a video slice acquisition request, and the determined slice identifier may be included in the video slice acquisition request. In this way, after receiving the video slice acquisition request, the cloud storage system can know which video slice should be provided to the playing terminal.
S27: and responding to the video slice acquisition request, reading the target video slice pointed by the slice identification from the second storage device, and providing the target video slice to the playing end.
In this embodiment, after the cloud storage system receives the video slice acquisition request, the slice identifier therein may be extracted. A target video slice matching the slice identification may then be queried from the second storage device. After the target video slice is inquired, the target video slice can be read and provided to the playing end.
In an embodiment, after receiving the video slice acquisition request, the cloud storage system may preferentially detect whether a video slice adapted to the video slice acquisition request exists in a cache. The video slice adapted to the video slice acquisition request may indicate that the identifier of the video slice is consistent with the slice identifier carried in the video slice acquisition request. If the video slices exist, the cloud storage system can directly provide the video slices in the cache to the playing end. If the target video slice does not exist in the second storage device, the cloud storage system may read the corresponding target video slice from the second storage device, and provide the read target video slice to the playing end.
It should be noted that, when the playing end sends the time shift request, the time shift request preferentially reaches the edge node of the CDN, so that the edge node may determine whether the index file and the video slice corresponding to the time shift request currently exist, and if so, may directly provide the corresponding index file and the video slice to the playing end. If not, the corresponding index file and video slice may be retrieved back from the cloud storage system according to the steps described in S21 to S27 above.
In an embodiment, after the cloud storage system feeds back the index file to the playing terminal, the index file may be written into a cache, so that when the cloud storage system receives an index file acquisition request pointing to the index file again, the index file stored in the cache may be fed back to a requesting party without reading a corresponding index file from the first storage device, thereby improving the feedback speed of the index file. Similarly, after the target video slice is provided to the playing end, the cloud storage system may write the target video slice into the cache, so that when a video slice acquisition request pointing to the target video slice is received again, the target video slice stored in the cache is fed back to the requesting party, and thus, the corresponding target video slice does not need to be read from the second storage device, and the feedback speed of the target video slice is increased.
Example four
Referring to fig. 5, the present application further provides a cloud storage system, where the cloud storage system includes a first storage device, a second storage device, and a processing module, where:
the first storage equipment is used for storing the index file uploaded by the video processing device;
the second storage device is used for storing a plurality of video slices uploaded by the video processing device and corresponding to the index file;
the processing module is used for receiving an index file acquisition request sent by a playing end; responding to the index file acquisition request, reading the index file from the first storage device, and feeding back the index file to the playing end, so that the playing end determines a slice identifier adapted to a current time-shifting time node according to the index file; receiving a video slice acquisition request sent by the playing end, wherein the video slice acquisition request comprises the determined slice identifier; and responding to the video slice acquisition request, reading the target video slice pointed by the slice identification from the second storage device, and providing the target video slice to the playing end.
Therefore, according to the technical scheme provided by the application, the recording and broadcasting work of the live broadcast video can be completed by the video processing device. When the live broadcast starts, the video processing device can acquire the live broadcast video and can record and broadcast the live broadcast video. In the recording and playing process, the video processing device may divide the live video into a plurality of video slices at specified time intervals, and create an index file of the plurality of video slices. Wherein, the index file can store the index information of each video slice. The index information may include, for example, a start playing time corresponding to the video slice, and may further include a file name of the video slice. In this way, the video processing apparatus may upload the plurality of divided video slices and the index file to the cloud storage system. When the video slices are stored, incremental storage can be performed, and the newly divided video slices can be written into the cloud storage system each time. When the index file is stored, the index file can be stored in an overlaying manner, and the index file stored in the cloud storage system can be overlaid with a new index file every time. In a cloud storage system, a video slice and an index file can be stored separately, and because the index file needs to be stored in a covering manner continuously, the reading and writing speed and performance of a storage device corresponding to the index file can be relatively high. And when the playing end needs to perform time shifting, the corresponding cache content can be preferentially acquired from the edge node of the content distribution network, and if the cache content does not exist in the edge node, the cache content can be acquired from the cloud storage system. Specifically, the playing end may first obtain an index file of the live video from the cloud storage system, and based on the index file, and in combination with the current time shift time node, may determine a file name corresponding to a reviewed video slice. Then, a video slice acquisition request including the file name may be sent to the cloud storage system, and the cloud storage system may thereby read the target video slice having the file name and provide the target video slice to the player. Therefore, according to the technical scheme provided by the application, the high-speed storage device is designed to be used for storing the index file, so that the access is more efficient, the CDN is combined with the cloud storage system, and the accessed content is cached on the CDN edge node, so that the access efficiency of the playing end is improved.
