[0021] As described in the background art section above, traditional web video recording solutions are usually implemented by manually operating a screen recording tool while the video is played at the original speed, which has problems such as long recording time and low recording efficiency. In view of this, the present disclosure discloses a web video recording solution that can improve the recording efficiency.

[0022] The following will describe the specific embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0023] Figure 1 It is a flowchart of a web video recording method according to an exemplary embodiment of the present disclosure, which mainly includes the following steps:

[0024] Step S102, load the web address of the web video to obtain the video tag of the web video.

[0025] Optionally, an automated simulation tool can be used to create a headless browser, and the web address of the web video can be loaded through the headless browser to obtain the video tag of the web video.

[0026] Optionally, the automated simulation tool (which can also be called a browser automated simulation tool) can include but is not limited to puppeteer, selenium, etc.

[0027] Optionally, the headless browser can include but is not limited to the headless chrome browser.

[0028] Exemplarily, puppeteer can be used to create a headless browser. By opening the headless browser and loading the web address of the web video (for example, the URL address), the video tag of the web video (which can also be called the video tag) can be obtained.

[0029] Step S104, identify the resource attributes of the video tag to obtain the audio data of the web video.

[0030] Optionally, an automated simulation tool can be used to identify the resource attributes of the video tag to determine the video source address of the web video, and a multimedia processing tool can be used to extract the audio resource from the video source address to obtain the audio data of the web video.

[0031] Optionally, the multimedia processing tool can include but is not limited to FFmpeg.

[0032] Exemplarily, puppeteer can be used to identify the src attribute of the video tag to determine the video source address of the web video, and FFmpeg can be used to extract the audio resource (for example, the wav file) from the video source address to obtain the audio data of the web video. By using this technical means, after performing the speed restoration processing on the audio data, the presence of noise in the audio data can be avoided to improve the sound quality effect.

[0033] Optionally, the playback rate of the obtained audio data can be 1x rate (i.e., playing at the original speed), but it is not limited thereto. The playback rate of the obtained audio data can also be 2x rate, 4x rate, etc. The present disclosure does not limit this.

[0034] Step S106, play the web video according to the playback rate of the video tag, and record the played web video to obtain the video data of the web video.

[0035] Optionally, an automated simulation tool can be used to set the playback rate of the video tag for the headless browser to play the web video according to the playback rate of the video tag, and the automated simulation tool can be used to perform a recording operation on the video playback area of the headless browser to obtain the video data of the web video.

[0036] In this embodiment, the playback rate of the video data of the web video obtained should be the same as the playback rate of the video tag.

[0037] Optionally, the playback rate of the video tag may include but is not limited to 2x speed, 4x speed, 6x speed, 8x speed, 16x speed, etc.

[0038] Optionally, during the process of playing the web video in a headless browser, an automated simulation tool can be provided to stop the recording operation when it detects that the end-play event of the video tag is triggered.

[0039] Exemplarily, puppeteer can be used to set the playback rate of the video tag (e.g., Nx speed), so that based on the playback rate of the video tag, the headless browser plays the web video at Nx speed in its video playback area. And puppeteer-stream is used to perform the recording operation on the video playback area of the headless browser, while listening for the end-play event of the video tag. Until it detects that the end-play event is triggered, stop the recording operation on the video playback area of the web video, thereby obtaining the video data of the web video, and the playback rate of the obtained video data is Nx speed.

[0040] Thus, in this embodiment, by setting the playback rate of the video tag, when playing the web video at Nx speed, the recording operation of the web video can be completed within 1 / N of the duration, thereby effectively shortening the recording operation duration of the video data.

[0041] Step S108, adjust the playback rate of the video data and / or the playback rate of the audio data, and merge the video data and the audio data with the same playback rate to obtain the recorded data of the web video.

[0042] Optionally, according to the given adjustment rate, the playback rate of the video data and / or the playback rate of the audio data can be adjusted so that the playback rates of both the video data and the audio data are the same as the adjustment rate, thereby obtaining the video data and the audio data with the same playback rate.

[0043] In this embodiment, the adjustment rate can be set to 1x speed, 2x speed, 4x speed, etc., and the present disclosure does not limit this.

[0044] Optionally, the playback rate of the video data can be adjusted according to the playback rate of the audio data, thereby obtaining the video data and the audio data with the same playback rate.

[0045] Optionally, the playback rate of the audio data can be adjusted according to the playback rate of the video data, thereby obtaining the video data and the audio data with the same playback rate.

[0046] Optionally, the playback rate of video data can be adjusted through the following steps: parse the video data, obtain the playback rate attribute of the video data, and modify the playback rate attribute of the video data to adjust the playback rate of the video data.

[0047] Optionally, a video attribute modification tool can be used to parse the video data, and based on this, modify the playback rate attribute of the video data.

[0048] Exemplarily, the mp4reader.js plugin can be used to parse the video data, obtain the timescale attribute of the video data, and adjust the playback rate of the video data by modifying the timescale attribute. For example, by modifying the timescale attribute, the playback rate of the video data can be adjusted from N times the rate to 1 time the rate. Thus, in this embodiment, by modifying the playback rate attribute (timescale attribute) of the video data, fast (e.g., second-level) playback rate conversion processing can be achieved, with relatively high data conversion processing efficiency.

[0049] Optionally, before using the video attribute modification tool to parse the video data, the original data format of the video data can be converted to obtain video data with a target data format, where the target data format is a data format recognizable by the video attribute modification tool.

[0050] Generally, the data format of the video data obtained using puppeteer-stream is usually the webm format. In this case, the data format of the video data can be first converted from the webm format to the mp4 format using FFmpeg, and then the mp4reader.js plugin can be used to parse the video data in the mp4 format.

[0051] Exemplarily, FFmpeg can be used to merge video data and audio data with the same playback rate to obtain the recorded data of the web page video (which can also be called audiovisual data). Since the data merging process performed using FFmpeg is a lightweight process, the data merging process can be quickly completed in a relatively short time.

[0052] In summary, the web page video recording solution provided in this embodiment directly extracts the audio data of the web page video from the video source address of the web page video by identifying the video tag of the web page video, and by setting the playback rate of the video tag, the recording operation of the video data of the web page video can be performed when playing the web page video at a multiple speed. Thus, the recording solution of the present disclosure can effectively shorten the operation duration of video recording and improve the recording efficiency of web page videos.

[0053] Figure 2A web page video recording method showing another exemplary embodiment of the present disclosure mainly includes the following steps:

[0054] Step S202: Use an automated simulation tool to create a headless browser, and load the web page address of the web page video through the headless browser to determine the video tag of the web page video.

[0055] In this embodiment, puppeteer can be used to create a headless chrome browser, and by opening the headless chrome browser to load the web page address of the web page video (such as an online teaching video), the video tag of the web page video can be determined.

[0056] Step S204: Use an automated simulation tool to identify the resource attributes of the video tag to determine the video source address of the web page video, and use a multimedia processing tool to obtain the audio data of the web page video from the video source address.

[0057] In this embodiment, puppeteer can be used to identify the src attribute of the video tag of the web page video, and based on this, determine the video source address of the web page video, and use FFmpeg to extract the audio resource (wav file) in the video source address, so as to obtain the audio data of the web page video. Among them, the playback rate of the obtained audio data can be the original rate, or 2 times rate, 4 times rate, etc.

[0058] Step S206: Use an automated simulation tool to set the playback rate of the video tag for the headless browser to play the web page video according to the playback rate of the video tag, and use an automated simulation tool to perform a recording operation on the video playback area of the headless browser to obtain the video data of the web page video.

[0059] In this embodiment, puppeteer can be used to set the playback rate (such as N times rate) of the video tag of the web page video, so that the headless chrome browser can play the web page video at a multiple rate (such as N times rate) in the video playback area of the headless chrome browser according to the playback rate of the video tag, and use puppeteer-stream in puppeteer to perform a recording operation on the video playback area of the headless chrome browser to obtain the video data of the web page video. Among them, the playback rate of the obtained video data of the web page video should match the playback rate of the video tag.

[0060] In this embodiment, the playback rate of the video tag may include but is not limited to 2 times rate, 4 times rate, 6 times rate, 8 times rate, 16 times rate, etc., and the present disclosure does not limit this.

[0061] In this embodiment, during the process of playing a web video by a headless browser (headless chrome browser) according to the playback rate of the video tag, puppeteer-stream can be used to listen for the end-play event (end event) of the video tag, and when detecting that the end-play event is triggered, stop the recording operation of the video playback area of the headless browser, so as to obtain the complete video data of the web video.

[0062] Step S208: Use a video attribute modification tool to adjust the playback rate of the video data according to the playback rate of the audio data, so as to obtain the converted video data of the web video.

[0063] In this embodiment, the mp4reader.js plugin can be used to parse the video data to obtain the playback rate attribute (timescale attribute) of the video data, and according to the playback rate of the audio data, modify the playback rate attribute (timescale attribute) of the video data to obtain the converted video data with the same playback rate as the audio data.

[0064] Optionally, before using the video attribute modification tool to modify the playback rate attribute of the video data, a multimedia processing tool can be used to convert the original data format of the video data of the web video into a target data format recognizable by the video attribute modification tool.

[0065] Specifically, the data format of the video data obtained by puppeteer-stream performing the recording operation is usually the webm format. Therefore, before using the video attribute modification tool to modify the playback rate attribute of the video data, FFmpeg can be used to convert the data format of the video data of the web video from the webm format (i.e., the original data format) to the mp4 format (i.e., the target data format) recognizable by the mp4reader.js plugin, so that the mp4reader.js plugin can smoothly perform the adjustment process of the playback rate of the video data.

[0066] Step S210: Use a multimedia processing tool to merge the converted video data of the web video and the web video audio data to obtain the recorded data of the web video.

[0067] In this embodiment, FFmpeg can be used to merge the converted video data and the audio data with the same playback rate to obtain the recorded data (audio-visual data) of the web video.

[0068] In summary, by using the web video recording solution based on the automated simulation tool (puppeteer) and the multimedia processing tool (FFmpeg) in this embodiment, one only needs to manually configure the web address (URL address) of the web video to be recorded, and then the automatic and fast web video recording operation can be realized, which can greatly improve the recording efficiency of the web video. In addition, since the solution of this embodiment belongs to lightweight data processing, it has the advantage of low system operation load.
