It will be understood by those skilled in the art that the structure shown in FIG. 2 is only a block diagram of a part of the structure related to the solution of the present application, and does not constitute a limitation on the server to which the solution of the present application is applied. The specific server may include a ratio. More or fewer components are shown in the figures, or some components are combined, or have different component arrangements.

Referring to FIG. 3, a video processing method applied to a server in an embodiment is provided, which is applicable to the server 120 in FIG. 1, and includes steps S310-S340.

S310: Receive a video request sent by the terminal.

The video request carries the source video identifier, the URL of the source video (Uniform Resource Locator), and the starting play time point. The source video corresponding to the source video identifier includes video segments that are sequentially connected at the beginning and the end of the video. It can be understood that the source video corresponding to the source video identifier includes video segments that are sequentially stitched together in the first and last time. For example, for the source video identified as A, it may be movie A, the duration is 90 minutes, and the movie A is end to end by each video segment according to time. The splicing in sequence may include, for example, 9 video clips (which may be the 1st-9th video clips), each video clip has a duration of 10 minutes, and each video clip has a start play time and an end time. That is, each video segment corresponds to a time range, and the corresponding time range of the first video segment is (0, 10), and the time range corresponding to the next video segment, that is, the second video segment is (10, 20), and so on. The time range corresponding to the ninth video segment is (80, 90), and the above nine video segments are spliced end to end in chronological order to form the source video A.

When a terminal requests playback of the source video from the server, due to factors such as the diversity of the source video format and the format of the video that can be played by the terminal, the server often needs to transcode the source video and send it to the terminal, so that the terminal can play normally. Each source video has its own unique identifier. The source video identifier can indicate the identity of the source video, so that the server can know which source video the terminal wants to request. The source video is stored in the server, and the source video is stored with a URL. The URL can be located to the location of the source video storage, and the source video can be read to obtain the source video. After receiving the video request sent by the terminal, the source video can be The URL of the source video gets the corresponding source video. When the server sends a video to the terminal, it needs to perform segmental transmission. That is, the source video includes video segments that are connected in sequence at each end of the time. After the video segment is transcoded, it is sent to the terminal to implement segmentation of the video. In addition, when the video request is made, the initial broadcast time point carried by the terminal is the time point at which the request source video starts playing. For example, if the user requests to play the movie A starting from the 30th minute, the starting playback time point is the 30th minute. If it is played at the beginning of movie A, the starting playback time point is the 0th minute.

S320: Acquire a transcoding parameter, and determine a destination video transcoding segment corresponding to the starting playing time point.

When the video clip needs to be transcoded later, it needs to be transcoded according to the transcoding parameter, and the transcoding parameter determines the effect of the transcoded video. In this embodiment, in order to adapt to the requirements of different terminals and different networks, the transcoding parameters may be determined according to the terminal information and the network information to obtain the transcoding parameters. The terminal information and the network information may be known from the video request sent by the terminal, that is, the video request may further include terminal information and network information. The terminal information may include a terminal model or/and a model of the terminal player, and the network information may include network speed or network throughput, etc., where the network information refers to network information corresponding to the network where the terminal is located.

The terminal needs to perform video playback by sending a video request, and the terminal requests the video segment corresponding to the starting playback time point, and the video segment corresponding to the transcoded video segment corresponding to the video segment is sent to the terminal, thereby requiring in the server Determining the destination video transcoding segment corresponding to the starting playback time point for subsequent transmission to the terminal for playback. The video segment corresponding to the starting playback time point in the source video is corresponding to the destination video transcoding segment, and the destination video transcoding segment is the segment after the video segment corresponding to the initial playback time point. The segment, the start time and the end time of the video segment and the corresponding video transcoding segment are correspondingly the same. After the starting playback time point is known, the video segment of the corresponding source video can be obtained, if the video segment has been stored. The video segment corresponds to the destination video transcoding segment after the transcoding, and the destination video transcoding segment corresponding to the starting playing time point is also obtained to determine the destination video transcoding segment. If not, the device needs to The video segment corresponding to the start playing time point is transcoded to determine the destination video transcoding segment.

S330: when the first stored video transcoding segment closest to the end time of the destination video transcoding segment and the starting time is after the end time meets a preset condition, according to the transcoding parameter, for each video segment The video segment of the destination transcoding segment with the closest end time and the starting time after the end time and the untranscoded video is transcoded to obtain the first video transcoding segment.

The server performs transcoding when there is a first stored video transcoding segment that satisfies a preset condition in the stored video transcoding segment to reduce the transcoding workload. As the terminal plays sequentially, as the playback progresses, what is needed is the chronological video transcoding segment after the destination video transcoding segment, if it is closest to the end time of the destination video transcoding segment, and starts The first stored video transcoding segment after the end time meets the preset condition, indicating that the transcoding condition is satisfied, that is, the first stored video transcoding segment may not be sufficient to support subsequent playback requirements, and transcoding is required. At this time, according to the transcoding parameter, the video segment of each video segment that is closest to the end time of the destination transcoding segment, the start time is after the end time, and is not transcoded is transcoded to obtain the first video transcoding. The segment, that is, the untranscoded video segment after the determined destination transcoding segment is transcoded to ensure the number of transcoded segments that can be sent to the terminal, ensuring playback quality.

In this embodiment, the untranscoded video segment may be a preset number of consecutive untranscoded video segments, and the number of the first video transcode segments is a preset number of segments.

After the video processing method is received, after receiving the video request sent by the terminal, the destination video transcoding segment corresponding to the initial playing time point needs to be determined, and further, it is determined that the end time of the destination video transcoding segment is the closest. And whether the first stored video transcoding segment after the end time meets the preset condition, and the transcoding is performed only when the first stored video transcoding segment satisfies the preset condition, which can be avoided. When the terminal requests the video, the transcoding of the entire video source is started, and a large amount of waste is generated when the user exits the video playback. The method in this embodiment only transcodes the video segment and the destination according to the transcoding parameter when the preset condition is met. The video clip with the latest end time of the segment and the start time after the end time is transcoded to obtain the first video transcoding segment, which greatly reduces the transcoding work and saves resources even if the user quits. Will not cause a lot of waste of resources

In one embodiment, the step of determining the destination video transcoding segment corresponding to the initial playing time point comprises: when the starting playing time point is within the time period of the stored video transcoding segment corresponding to the source video identifier, Obtaining the destination video transcoding segment from the stored video transcoding segment; when the starting playing time point is not within the time period of the stored video transcoding segment corresponding to the source video identifier, starting the playing time in the source video The video segment corresponding to the point is transcoded, and the destination video transcoding segment corresponding to the starting playback time point is obtained.

In determining the destination video transcoding segmentation process, there are two cases, one is that in the stored video transcoding segment, there is already a video transcoding segment corresponding to the starting playing time point, and each is stored. The video transcoding segment has a corresponding start and end time, and can determine whether the stored video transcoding segment is determined by determining whether the starting playing time point is within the time period of the stored video transcoding segment corresponding to the source video identifier. Whether there is a destination video transcoding segment corresponding to the initial playing time, that is, if the video transcoding segment corresponding to the video segment where the starting playback time point required by the terminal is already stored, there is no need to perform transcoding. The destination video transcoding segment corresponding to the initial playing time point is obtained directly from the stored video transcoding segment. The other is that there is no video transcoding segment corresponding to the starting playing time point in the stored video transcoding segment, and the terminal needs to play the video transcoding segment corresponding to the starting playing time point. The video segment corresponding to the starting playing time point in the source video needs to be transcoded to obtain the destination video transcoding segment corresponding to the starting playing time point, and the subsequent terminal can perform the playback after receiving the destination video transcoding segment.

In one of the embodiments, the first stored video transcode segment satisfies a preset condition when the consecutive number of first stored video transcode segments is less than a preset number.

In order to ensure that the terminal can receive the destination video transcoding segment sent by the server smoothly, and achieve smooth playback, and save transcoding resources, the end time of the segmentation with the destination video transcoding needs to be the closest, and the starting time is The continuous number of the first stored video transcoding segments after the end time is compared with the preset number. When the consecutive number is less than the preset number, it indicates that the current first stored video transcoding segment may not be sufficient to support the playback of the terminal. Requirement, in order to ensure the smoothness of the destination video transcoding segment sent to the terminal, and to save the transcoding resources, the end time of each of the video segments and the destination transcoding segment is the closest, and the starting time is in the The video segment after the end time and not transcoded is transcoded to obtain a first video transcoding segment, and preferably, the transcoded video segment is transcoded for a preset number of segments, without The video segment of the code is transcoded to avoid transcoding a large number of untranscoded video segments, which consumes a lot of resources and increases the transcoding burden.

Referring to FIG. 4, in one embodiment, after obtaining the destination video transcoding segment from the stored video transcoding segment, the method further includes:

S340: Return, to the terminal, the first request response information, where the first request response information includes a URL of the destination video transcoding segment and media information, where the media information includes a duration and a start time point;

S350: Receive and respond to the first fragment playback request sent by the terminal according to the first request response information, and return, to the terminal, first fragmentation response information, where the first fragmentation response information includes the destination video transcoding segment. The destination video transcode segment corresponding to the URL, and the first fragment playback request carries the URL of the destination video transcoding segment.

The above steps S340-S350 are applied to the server. After the server obtains the destination video transcoding segment from the stored video transcoding segment, the destination video transcoding segment may also be sent to the terminal, and the terminal receives the It can be played later. In this embodiment, since the video transcoding segment corresponding to the initial playing time point, that is, the above-mentioned destination video transcoding segment, already exists in the stored video transcoding segment, the destination video transcoding segment The segment has its corresponding URL. When the server sends the destination video transcoding segment to the terminal, the first request response information carrying the URL of the destination video transcoding segment is first returned to the terminal, and the terminal receives the first request. Sending a first fragment playback request carrying the URL of the destination video transcoding segment to the server, in response to the information, requesting the destination video transcoding segment, and after receiving the first fragment playback request, the server returns the destination to the terminal. The destination video transcode segment corresponding to the URL of the video transcoding segment can be played by the terminal receiving. In addition, the first request response information may further include media information such as the duration and the start time point, and after being sent to the terminal, the terminal may notify the terminal of the media information such as the duration of the destination video transcoding segment and the start time point, and the terminal may also The above media information is displayed for the user to watch.

In one embodiment, after obtaining the destination video transcoding segment corresponding to the initial playing time point, the destination video transcoding segment is returned to the terminal.

That is, in this embodiment, the video transcoding segment corresponding to the starting playing time point is not stored in the stored video transcoding segment, and the transcoding is required to obtain the destination video transcoding segment, and at this time, the purpose is not The video transcode segment is stored, and there is no corresponding URL address. The server directly transmits the destination video transcode segment obtained by the transcoding to the terminal, and the terminal receives and plays.

In one embodiment, the video processing method further includes the steps of:

When receiving the video exit request carrying the source video identifier sent by the terminal, stopping the transcoding, and when the number of times of playing or/and the playing integrity of the first video transcoding segment meets the corresponding preset value, the first video is used. Transcoding segmentation storage, updating the stored video transcoding segment, the playing integrity of the first video transcoding segment is the length of time of the first video transcoding segment sent to the terminal and the segmentation of the first video transcoding segment The ratio of the duration.

That is, when the user requests to quit the video through the terminal, the user sends a video exit request to the server. When the server receives the video exit request, if the code is being transcoded, the code is immediately stopped to reduce the transcoding workload and save resources. At the same time, it is also necessary to analyze the playing condition of the first video transcoding segment (corresponding to the playing times, that is, the playing heat) and the user dragging situation (corresponding to the playing integrity), when the first video transcode segment is played or And when the playback integrity satisfies the corresponding preset value, indicating that the first video transcoding segment is frequently played or/and the user dragging is good during playback, the first video transcoding segment may be performed. The storage avoids repeated transcoding when the subsequent terminal requests the first video transcoding segment, and saves the transcoding resource.

It can be understood that, since the number of the first video transcoding segments is more than one, that is, the number of the first video transcoding segments may be the preset number of segments, the number of times of playing or/and the number of the first video transcoding segments is obtained. After playing the completeness degree, the first video transcoding segments may be sorted according to the number of times of playing or/and the playing integrity of each first video transcoding segment, and the number of playing times or/and the fullness of the playing integrity is advanced. A plurality of first video transcode segments are stored for storage to ensure the playback popularity or/and integrity of the stored first video transcode segments.

In addition, since the user needs to watch the video, generally starting from the beginning, the video transcoding segment corresponding to the beginning time of the source video is highly likely to be requested, and in order to save the transcoding resource, it can be stored, that is, received. After the video exit request is sent, after the code is stopped, it is determined whether the source video start time is within the time period of the stored video transcode segment corresponding to the source video identifier, and if not, the beginning of the source video The video segment corresponding to the time is transcoded, and the first video transcode segment is obtained and stored.

In one embodiment, after the transcoding is stopped, when the number of times of playing or/and the fullness of the playback of the first destination video transcoding segment meets the corresponding preset value, the first destination video transcode is segmentally stored and updated. The video transcoding segment is stored, wherein the first destination video transcoding segment is a destination video transcoding segment that is not in the stored video transcoding segment, and the playback integrity of the first destination video transcoding segment is The ratio of the length of time of the first destination video transcoding segment sent to the terminal to the duration of the first destination video transcoding segment.

That is, the server not only needs to analyze the playing condition and the user promotion situation of the first video transcoding segment to determine whether to store, but also needs to analyze the playing condition of the first destination video transcoding segment and the user dragging situation. When the number of playbacks of the video transcoding segment of a destination or/and the integrity of the playback meet the corresponding preset value, it indicates that the first destination video transcoding segment is often played or/and the user drags during playback is good. The first destination video transcoding segment may be stored to prevent repeated transcoding when the subsequent terminal requests the first destination video transcoding segment, thereby saving transcoding resources.

Referring to FIG. 5, the process of the video processing method described above is specifically described in a specific embodiment, and the video processing method is applied to the server 120.

First, the video will be input into the server 120, which can be decoded to obtain the source video. After the source video is segmented, each video segment can be obtained. The steps of the video processing method of this implementation are as follows:

(1) The server 120 receives the video request from the terminal 110, and can obtain the source video according to the URL in the video request.

(2) According to the terminal information and network information in the video request, analyze the characteristics of the terminal and the network, and determine the transcoding parameters, and the transcoding parameters may include the code rate and the resolution.

(3) The index management module 124 is activated (the function of the index management module 124 can be implemented by the HTTP server in FIG. 5), and the initial playback time is searched in the index management module 124 according to the initial playback time point and the source video identifier carried in the video request. Whether the time point is within the time period of the stored video transcoding segment corresponding to the source video identifier, that is, whether the transcoded slice requested by the terminal is in the stored video transcoding segment. If, at the stored video transcoding segment, the media information (time length, start time, encryption, etc.) of the destination video transcoding segment corresponding to the initial playback time point and the destination video transcoding segmentation The URL is written into the index file, that is, the file suffixed as m3u8, and the first request response information is returned to the terminal 110 to carry the information of the file terminal suffixed as m3u8, and the terminal 110 sends the information to the server 120 according to the URL of the destination video transcoding segment. Carrying the URL first fragment playback request of the destination video transcoding segment, and the server 120 returns the destination video transcoding corresponding to the URL of the destination video transcoding segment to the terminal 110 in response to the first fragment playback request. Segmentation, the terminal 110 can play the video transcoding segment of the destination.

(4) The transcoding module 125 determines whether to perform transcoding according to a preset preset number. The predetermined number of values may be determined based on the ratio of the duration of the existing transcoded consecutive destination video transcoding to the current speed of the server 120 spitting data. Transcoding is performed when the consecutive number of first stored video transcode segments closest to the end time of the destination video transcode segment and the start time is less than the preset number, Transcoding parameters, transcoding each video segment of each of the video segments that is closest to the end time of the destination transcoding segment, the start time is after the end time, and the number of preset segments that are not transcoded Obtain a preset number of segments of the first video transcoding segment without transcoding the entire source video. The preset number of segments may be determined by the network metric of the current server and the resource occupancy rate. When the consecutive number of the first stored video transcoding segments is not less than the preset number, it indicates that the transcoding condition is not satisfied, and no transcoding is performed at this time, and the transcoding resources are saved.

(5) When performing transcoding, the transcoding parameter is sent to the distributed system, and the transcoding of the untranscoded video segment is obtained, the first video transcoding segment is obtained, and an index is established, and the web server 126 is present. It can be sent to the terminal via the HTTP protocol.

(8) When the server 120 receives the exit video request sent by the terminal, that is, the user exits the video viewing, the server 120 stops the transcoding.

(10) After receiving the exit video request and exiting the transcoding, the server 120 starts the TOP transcoding segmentation statistics module 127, and switches to the first video according to the number of times of the first video transcoding segment or/and the integrity of the playback. The code segments are sorted, and the preset number of first video transcode segments with the number of play times or/and the fullness of playback are stored to ensure the playback popularity or/and integrity of the stored first video transcode segments. degree.

In summary, the index management module 124 can be added to manage the stored video transcoding segments to prevent repeated transcoding. The transcoding module can avoid the transcoding of the entire source video when the terminal requests the video, which greatly reduces the transcoding workload. The TOP transcoding segmentation statistics module 127 is added, and the preset number of first video transcoding segments with the number of play times or/and the fullness of the playback integrity may be stored, thereby counting the segments repeatedly viewed by the user, and reducing the transcoding. Quantity and storage.

The video processing method in this embodiment is applied to the server 120, and the video broadcast and on-demand of the terminal 110 can be implemented. The amount of transcoding by the server 120 can be reduced and storage resources can be saved. According to the current volume of cloud storage, it can save 40% of the transcoding amount and 80% of the storage resources. It also provides a fast first-screen user experience and enhances product competitiveness.
