Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1a is a flowchart of a video playing method in one embodiment of the present invention, which is applicable to reducing time consumption between video uploading and video playing when playing a video using a streaming media, and the method may be executed by a video playing apparatus, which may be implemented by hardware and/or software, and may be generally integrated in a computer device, such as a server, and used in cooperation with a client. As shown in fig. 1a, the method comprises:
and 110, receiving the uploaded target video, and generating a video index file corresponding to the target video in real time.
In this embodiment, the uploaded target video may be in any format, for example, a video in MP4, WebM, Ogg, Flv, or the like. The video index file can be an m3u8 index file, m3u8 is one of m3u, the encoding mode is utf-8 encoding, and the m3u8 index file is actually used for resolving the request address of the corresponding video clip placed on the server, so that online playing is realized.
Optionally, receiving the uploaded target video, and generating a video index file corresponding to the target video in real time may include: receiving the uploaded target video and determining the total duration of the target video; calculating the starting and stopping playing time of each video clip after the target video is sliced according to the preset video clip duration and the total duration; and generating a video index file corresponding to the target video according to the starting and ending playing time of each video clip and the request address distributed to each video clip.
In this embodiment, as shown in fig. 1b, after receiving the uploaded target video in any format, an FFmpeg tool may be used to obtain a total duration of the target video, then according to a predetermined video segment duration, a start playing time and an end playing time of each video segment obtained after the target video is sliced are calculated, and a corresponding request address is pre-allocated to each video segment. For example, the total duration of the target video is 20 minutes, the duration of the preset video segment is 30 seconds, the starting playing time of the first video segment obtained after the target video is sliced corresponds to 0 th second of the target video, the ending playing time corresponds to 30 th second of the target video, and the allocated request address may be xxx. And generating an m3u8 index file corresponding to the target video according to the starting and stopping playing time and the request address of each video clip.
FFmpeg is a specialized multimedia framework that can decode, encode, transcode, multiplex, demultiplex, stream, filter, and play almost all forms of media files. The core of the method is a video and audio processing tool based on a command line, and the method is mainly used for scenes such as video transcoding, basic editing (pruning and merging), video zooming, post-effect production and the like.
In the embodiment, after the target video is uploaded, slice transcoding is not directly performed, but the starting and ending playing time of each video segment corresponding to the transcoded target video slice is calculated first, and a request address is allocated to each video segment, so that an m3u8 index file can be generated before the target video is switched and transcoded, and a client can request the server for video playing without waiting for the time of slice transcoding processing on the target video.
And step 120, responding to a playing request of the client to the target video, and returning a video index file corresponding to the target video so that the client determines a target video segment to be played currently.
In this embodiment, as shown in fig. 1b, after generating the m3u8 index file, in response to a play request of the client for the target video, the server returns the m3u8 index file corresponding to the target video to the client, so that the client obtains the start-stop play time and the request address corresponding to each video clip of the target video by parsing the m3u8 index file, and determines the target video clip to be currently played according to the video play time selected by the user on the target video.
In this embodiment, the storage location of the file data of each video clip is not in the static directory, but the file data is read by the backend program and then returned. That is, when the server receives the request for acquiring the video segment, it first determines whether the corresponding file data exists locally, if not, it transcodes the segment, if so, it directly reads and returns.
Optionally, in response to an acquisition request of the client for the target video segment, acquiring file data corresponding to the target video segment and returning the file data to the client, which may include: responding to an acquisition request of a client to a target video clip, and judging whether file data corresponding to the target video clip exists locally; if the target video clip does not exist, extracting the starting and ending playing time of the target video clip from the acquisition request; and carrying out slice transcoding on the target video according to the starting and stopping playing time by using an FFmpeg tool to generate file data corresponding to the target video segment, and returning the file data to the client.
In this embodiment, as shown in fig. 1b, when an acquisition request of a client for a target video segment is received, it is first determined whether file data of the target video segment exists locally, and if so, the corresponding file data is directly read and returned to the client. If not, using an FFmpeg tool to slice the target video file according to the starting and ending playing time of the target video segment carried in the request, and transcoding the cut video segment to obtain file data in a specified format, such as a ts format file. Since the time consumed by slice transcoding is typically short, the client's perception of the slice transcoding process is not obvious. And the server reads the ts format file of the target video clip and returns the ts format file to the client for playing, and simultaneously stores the ts file of the target video clip so as to directly return when the target video clip is requested next time.
Wherein TS is a packaging format performed by shooting with a japanese high-definition camera, and is collectively called MPEG 2-TS. ts is an abbreviation for "TransportStream". The MPEG2-TS format is characterized by the requirement that it can be decoded independently from any segment of the video stream.
In this embodiment, by pre-calculating and generating the m3u8 index file of the target video, when the client requests to start playing from the specified video segment according to the m3u8 index file, the server can directly read the file data of the target video segment and return the file data without sequentially acquiring all the file data before the target video segment, and after the video is uploaded, the specified video segment is played in real time according to the user requirement.
In the embodiment of the invention, a server receives an uploaded target video and generates a video index file corresponding to the target video in real time; responding to a playing request of a client to a target video, returning a video index file corresponding to the target video so that the client determines a target video segment to be played currently; the method and the device respond to the acquisition request of the client to the target video clip, acquire the file data corresponding to the target video clip and return the file data to the client, solve the problem that the time consumption from video uploading to video playing is long when the streaming media is used for playing in the prior art, and realize that the video can be played after the video uploading is completed in the scene that the streaming media plays the video.
Example two

As shown in fig. 2, the method includes:
In this embodiment, when a user clicks a target video to request playing, or clicks a designated position of a playing progress bar of the target video to request playing from a designated time point of the target video, the client sends a playing request for the target video to the server to obtain an m3u8 index file corresponding to the target video. The m3u8 index file is generated by the steps that after the server receives the uploaded target video, the server does not perform slice transcoding on the target video, the FFmpeg tool is directly used for obtaining the total duration of the target video, and the total duration is calculated in real time according to the preset duration of the video segment. The M3u8 index file includes the start and stop playing time and the request address of each video clip obtained after the target video is sliced.
And step 220, analyzing the video index file returned by the server, and determining a target video segment matched with the playing time point corresponding to the click playing operation.
In this embodiment, after acquiring the m3u8 index file returned by the server, the client analyzes the m3u8 index file to acquire the start-stop play time and the request address corresponding to each video clip of the target video, matches the video play time point selected by the user on the target video through a click operation with the start-stop play time of each video clip, and determines the target video clip to be played currently.
In this embodiment, after determining a target video segment to be currently played, the client sends an acquisition request of the target video segment to the server, receives file data returned by the server, and locates to a video playing time point selected by the user to start playing. After receiving the acquisition request of the target video clip, the server firstly judges whether a ts file storing the target video clip exists locally, and if so, directly reads the corresponding ts file and returns the ts file to the client for playing. And if not, using an FFmpeg tool to slice the target video file according to the starting and ending playing time of the target video segment carried in the request, transcoding the cut video segment to obtain a ts file, and returning the ts file to the client for playing.
In this embodiment, the server calculates and generates the m3u8 index file of the target video in advance, and the client can start playing from the specified video clip according to the request of the m3u8 index file, at this time, the server can directly read the file data of the target video clip and return the file data without sequentially acquiring all the file data before the target video clip, and after the video is uploaded, the specified video clip is played in real time according to the user requirement.
In the embodiment of the invention, a client responds to a click playing operation of a target video and sends a playing request of the target video to a server so as to obtain a video index file corresponding to the target video; the video index file is generated by the server in real time according to the received target video; analyzing a video index file returned by the server, and determining a target video segment matched with a playing time point corresponding to the click playing operation; the method and the device send the acquisition request of the target video clip to the server, and play and display the file data of the target video clip returned by the server, solve the problem that the time consumption from video uploading to video playing is long when the streaming media is used for playing in the prior art, and realize that the video can be played after the video uploading is finished in the scene of playing the video by the streaming media.
