[0041] It should be understood that Figure 1 The number of electronic devices in the embodiment is only for illustration. Any number of electronic devices may be provided according to implementation requirements.

[0042] Continue to refer Figure 2, shows a process 200 of some embodiments of the video content caching method according to the present disclosure. The video content caching method comprises the following steps:

[0043] Step 201, obtaining a video link corresponding to a target video.

[0044] In some embodiments, the execution subject of the above-mentioned video content caching method (for example Figure 1 The electronic device 101 shown in the figure can obtain the video link corresponding to the target video through a wired connection or a wireless connection. The target video can be a video to be played. In practice, the target video can be a short video. The video link can be a download link (Uniform Resource Locator, URL) corresponding to the target video.

[0045] Step 202: parse the link additional information corresponding to the video link.

[0046] In some embodiments, the execution subject may parse the additional link information corresponding to the video link. The additional link information may be additional information included in the video link that is associated with the video loading size information. In practice, the additional link information may include: the total duration of the target video, the total size occupied by the target video, and the image position of each key frame image.

[0047] As an example, the execution subject may use a preset regularization formula to parse the link additional information corresponding to the video link. The preset regularization formula is a formula set based on the connection form of the link and used to extract the link additional information.

[0048] In some optional implementations of some embodiments, parsing the link additional information corresponding to the video link may include the following steps:

[0049] In the first step, the execution subject may create preloading task information for the video link. The preloading task information may be task information corresponding to the preloading task. In practice, the task information may be a task identifier. The preloading task may be a task related to preloading the video. In practice, the preloading task includes: a parsing task corresponding to the link additional information. The parsing task corresponding to the link additional information may be a task for parsing the link additional information from the video link.

[0050] In a second step, the execution subject may perform link resolution for the video link according to the preloading task corresponding to the preloading task information to obtain the link additional information.

[0051] As an example, the execution subject may perform link parsing for the video link according to the parsing task corresponding to the link additional information to obtain the link additional information.

[0052] In some optional implementations of some embodiments, the above-mentioned link additional information is generated by the following steps:

[0053] In the first step, the received target video is transcoded to obtain the image occupancy information corresponding to at least one target key frame image, the header file occupancy information for the at least one target key frame image, and the video bit rate. The target key frame image may be a frame image in the target video whose corresponding content is key content. Specifically, the number of images of the target key frame image included in the at least one target key frame image may be preset. Specifically, the number of images corresponding to the at least one target key frame image is "1". It should be noted that the target video includes: a key frame image sequence. The at least one target key frame image may be the first at least one image in the key frame image sequence. For example, the at least one target key frame image may be the first key frame image in the target video. The image occupancy information may be the sum of the byte sizes of the images corresponding to the target key frame images included in the at least one target key frame image. The header file occupancy information may be the total image occupancy information corresponding to at least one image before the at least one target key frame image in the mook file in the target video. For example, the target video includes an image sequence. The image sequence includes: a first image, a second image, a third image, a fourth image, a fifth image, a sixth image, and a seventh image. The at least one target key frame image is the sixth image. The header file occupancy information may be the sum of the total byte sizes of the images corresponding to the first image, the second image, the third image, the fourth image, and the fifth image. In practice, the mook file includes image offset position information corresponding to the image. The image offset position information may represent the image position of the image in the image sequence included in the target video.

[0054] In practice, first, the above-mentioned execution subject can use the target video transcoding software to generate multiple transcoded files for the target video. Then, find at least one target key frame image from the multiple transcoded files. Then, determine the image occupancy information corresponding to the at least one target key frame image. Then, obtain the image offset position information for at least one target key frame image from the mook file in the multiple transcoded files. Then, determine the header file occupancy information corresponding to the image offset position information. Then, obtain the video byte occupancy size and the total video duration corresponding to the target video from the multiple transcoded files. Finally, divide the video byte size by the video duration to obtain the video bit rate.

[0055] As an example, Figure 3As shown in FIG. 1 , a schematic diagram of obtaining image occupancy information corresponding to a key frame image is shown. Among them, the key frame image can be Figure 3 The image corresponding to the "stsz file" in the image occupancy information of the image corresponding to the "stsz file" is "64708 bytes".

[0056] As an example, Figure 4 As shown in FIG. 1 , a schematic diagram of obtaining the header file occupancy information is shown. Among them, the key frame image is Figure 3 The image corresponding to the "stsz file" in the header file can be the total image occupancy information corresponding to the image file corresponding to the "stco file" before the key frame image. The total image occupancy information can be "131306 bytes".

[0057] The second step is to generate the above-mentioned video preliminary loading content occupancy information based on the above-mentioned image occupancy information and the above-mentioned header file occupancy information.

[0058] As an example, the execution subject may add the image occupancy information and the header file occupancy information to obtain the first added information as the video initial loading content occupancy information. For example, the image occupancy information is 64708 bytes. The header file occupancy information is 131306 bytes. Then the video initial loading content occupancy information may be 196014 bytes.

[0059] The third step is to generate the above-mentioned link additional information according to the above-mentioned video preliminary loading content occupancy information and the above-mentioned video bit rate.

[0060] As an example, the execution subject may concatenate the video initial loading content occupancy information and the video bit rate to generate link additional information. For example, the video initial loading content occupancy information is 196014 bytes. The video bit rate is 2197000 kbs. Then the link additional information may be "196014-2197000".

[0061] Optionally, after the "third step", the above steps further include:

[0062] In the first step, the link additional information and the video loading link corresponding to the target video are merged to generate the video link.

[0063] As an example, the link additional information and the video loading link corresponding to the target video may be spliced ​​to obtain a spliced ​​link as a video link.

[0064] The second step is to send the video link to a video playback terminal. The video playback terminal may be a terminal for playing videos. For example, the video playback terminal may be a terminal for playing short videos.

[0065] Step 203: Generate a video preload amount for the target video according to the link additional information.

[0066] In some embodiments, the execution subject may generate a video preload amount for the target video according to the link additional information. The video preload amount is a cache amount for preloading the target video. That is, the video preload amount may represent the byte occupancy of the video content preloaded by the target video.

[0067] As an example, the additional information for the link includes: the size of the video occupied in bytes and the total duration of the video corresponding to the target video. First, the above-mentioned execution entity can multiply the size of the video occupied in bytes by the first ratio to obtain the multiplied occupied byte size information. Then, the corresponding frame image in the target video corresponding to the multiplied occupied bytes is determined as the first target image. Next, the total duration of the video is multiplied by the second ratio to obtain the multiplied duration ratio. Next, the corresponding frame image in the target video corresponding to the above-mentioned multiplied duration ratio is determined as the second target image. Furthermore, the image with the earliest corresponding image time is filtered out from the first target image and the second target image as the video preloading cutoff image. Finally, the image byte size information corresponding to the image sequence in the target video before the video preloading cutoff image is determined as the video preloading amount.

[0068] In some optional implementations of some embodiments, the preloading task further includes: a video preloading amount generation task. The video preloading amount generation task may be a task for generating a video preloading amount according to link additional information.

[0069] And the execution subject may utilize the video preload amount generation task to generate the video preload amount for the target video according to the link additional information.

[0070] Step 204 , executing preloading of the video content corresponding to the target video, and obtaining the video preloading content corresponding to the loading amount equal to the video preloading amount.

[0071] In some embodiments, the execution subject may preload the video content corresponding to the target video to obtain the video preload content corresponding to the video preload amount, wherein the video preload content may be a sub-video in the target video.

[0072] In some optional implementations of some embodiments, the preloading task further includes: a preloading execution task. The preloading execution task may be a task for preloading video content.

[0073] And the execution subject can use the preloading execution task to execute the preloading of the video content corresponding to the target video, and obtain the video preloading content whose corresponding loading amount is the video preloading amount information.

[0074] Step 205: cache the video preloaded content.

[0075] In some embodiments, the execution entity may cache the video preloaded content.

[0076] As an example, the above execution entity may cache the video preload content locally.

[0077] In some optional implementations of some embodiments, after step 205, the steps further include:

[0078] In response to detecting the playback information for the target video, the execution subject may play the pre-cached video preload content and continue to load the remaining video content to achieve the video playback of the target video. The remaining video content is the video content corresponding to the target video minus the video preload content.

[0079] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the video content caching method of some embodiments of the present disclosure, by adaptively preloading the target video, the normal playback of the target video can be effectively achieved under the premise of consuming less bandwidth and ensuring the start-up speed. Specifically, the reason for the serious waste of bandwidth when the relevant target video is played normally is that the fixed content occupied size corresponding to the preloaded video content is a fixed value, and the problem of large fixed content occupied size may occur, resulting in serious bandwidth waste. Based on this, the video content caching method of some embodiments of the present disclosure first obtains the video link corresponding to the target video. Here, obtaining the video link is not only used to obtain the video to be played, but also used to parse the size information of the video content to be preloaded later. Then, the link additional information corresponding to the above video link is parsed for subsequent determination of the size information of the preloaded video content. Furthermore, according to the above link additional information, the video preload amount for the above target video can be accurately generated. Among them, the above video preload amount is the cache amount for preloading the target video. Here, according to the video situation of the target video, the corresponding video preload amount can be adaptively generated, avoiding the problem of bandwidth waste caused by the fixed content size, so that the target video can be preloaded under the premise of less bandwidth in the future to ensure the normal playback of the target video. Next, the preloading of the video content corresponding to the above-mentioned target video is performed to obtain the video preload content with the corresponding loading amount as the above-mentioned video preload amount to ensure the normal playback of the subsequent target video. Finally, the above-mentioned video preload content is cached so that the subsequent playback device can obtain the video preload content that does not need to be loaded in real time to avoid the problem of slow playback speed. In summary, by linking additional information, the video preload size information for the target video can be adaptively generated, so that the normal playback of the target video can be effectively achieved under the premise of consuming less bandwidth and ensuring the playback speed.

[0080] Further references Figure 5 , shows a process 500 of another embodiment of the video content caching method according to the present disclosure. The video content caching method comprises the following steps:

[0081] Step 501, obtaining a video link corresponding to a target video.

[0082] Step 502: parse the link additional information corresponding to the video link.

[0083] Step 503: Generate target duration video occupancy information according to the above video bit rate and preset value.

[0084] In some embodiments, an execution entity (e.g. Figure 1The electronic device 101 shown can generate the target duration video occupancy information according to the above video bit rate and the preset value. The above link additional information includes: video initial loading content occupancy information and video bit rate. The video initial loading content occupancy information can be the content occupancy information of the preliminarily determined video loading content. For example, the preset value can be 80. The target duration video occupancy information can be the information occupied by the target duration video.

[0085] As an example, the execution subject may divide the video bit rate by the preset value to obtain the target duration video occupancy information.

[0086] Step 504: Generate the video preload amount according to the target duration video occupancy information and the video initial loading content occupancy information.

[0087] In some embodiments, the execution subject may generate the video preload amount according to the target duration video occupancy information and the video initial loading content occupancy information.

[0088] As an example, the execution subject may add the target duration video occupancy information and the video initial loading content occupancy information to obtain the video preloading amount.

[0089] Step 505 , executing preloading of the video content corresponding to the target video, and obtaining the video preloading content corresponding to the video size corresponding to the video preloading size information.

[0090] Step 506: cache the video preloaded content.

[0091] In some embodiments, the specific implementation of steps 501-502, 505-506 and the technical effects thereof can be referred to in Figure 2 The steps 201-202 and 204-205 in the corresponding embodiment are not described in detail here.

[0092] from Figure 5 It can be seen that Figure 2 Compared with the description of some corresponding embodiments, Figure 5 The process 500 of the video content caching method in some corresponding embodiments can effectively achieve normal playback of the target video while ensuring no waste of bandwidth and ensuring the start-up speed by linking the video initial loading content occupancy information and video bit rate included in the additional information.
