Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In the research and development process of the applicant, the browser in the prior art realizes transcoding of a multimedia file by using a Javascript technology, but the Javascript technology belongs to a weak type language and is a single thread, the data and logic processing capability is poor, only the encapsulation layer of the multimedia file can be converted to the maximum extent, the encoding layer of the multimedia file cannot be encoded and decoded, and if the transcoding purpose is to be achieved, more performance is lost, and more memory and computing resources are wasted. However, this is not feasible for transcoding compression techniques, since forcing transcoding using Javascript techniques results in resources being restricted by the browser, or results in a browser crash directly. Therefore, the prior art realizes the transcoding of the video file by the browser by calling the transcoding support of the server. However, this causes a problem that the transcoding performance of the browser itself and the transcoding efficiency are low.
Fig. 1 is a flowchart of a transcoding method for a video file, which is disclosed in an embodiment of the present application, and the embodiment can be applied to a situation where a browser transcodes a video file to obtain a video transcoding file. The method of the embodiment can be executed by a transcoding device of a video file, the device is configured in a client, can be implemented by software and/or hardware, and can be integrated on any electronic device with computing capability.
As shown in fig. 1, the method for transcoding a video file disclosed in this embodiment may include:
s101, decoding a target video file to be transcoded through a browser in a client to obtain original data, and encoding the original data through the browser to obtain encoded data.
The client includes, but is not limited to, a smart phone, a tablet computer, a notebook computer, or any electronic device installed with an intelligent operating system. The browser is installed in the client in the form of software, and is used for displaying information streams such as texts, pictures, videos, audios and the like to a user. The target video file is composed of video pictures and audio information, and the formats of the target video file include, but are not limited to, mp4, avi, flv, and the like.
Specifically, a browser in a client acquires a target video file to be transcoded, where the target video file may be uploaded to the browser by a local client, or acquired from any webpage information by the browser through the internet, and the acquisition mode includes implementation by a Javascript technology, and this embodiment does not limit the source of the target video file. The browser firstly reads data information of a target video file, such as mp4 format data or avi format data, by using Javascript technology, and stores the data information of each video frame in a pre-established buffer, so that the subsequent browser can extract the data information from the buffer for processing. And after the data information is read, the browser extracts the data information of each video frame from the buffer area, and decodes the data information of each video frame through a pre-installed decoding device to obtain the original data of each frame. After the original data of each frame is obtained, the browser encodes the original data of each frame through a pre-installed encoding device to obtain encoded data of each frame. The decoding device can be a browser plug-in with a decoding function, or a decoder and the like; the encoding device may be a browser plug-in with an encoding function, or an encoder or the like.
Optionally, the original data includes video original data and audio original data, and the encoded data includes video encoded data and audio encoded data. The browser decodes each frame in the target video file through a decoding device to obtain video original data and audio original data of each frame; and coding the video original data and the audio original data of each frame by the coding device to obtain the video coded data and the audio coded data of each frame. The audio encoding data and the video encoding data are obtained by respectively encoding the audio original data and the video original data, and a foundation is laid for the subsequent client to respectively download the audio encoding data and the video encoding data.

And S102, downloading the coded data in the browser to a client to obtain a video transcoding file.
Specifically, the client monitors the encoding operation of the browser on the original data in real time, and if the client monitors that the browser completes the encoding operation on each frame, the client initiates a data downloading request to the browser so as to download encoded data obtained by encoding from the browser to the client, and obtain a video transcoding file obtained by transcoding a target video file.
Optionally, S102 includes:
and downloading the video coding data and the audio coding data in the browser to the client, and merging and packaging the downloaded video coding data and audio coding data to obtain a video transcoding file.
Specifically, the client downloads the video encoding data and the audio encoding data from the browser according to preset downloading rules, wherein the downloading rules preferably adopt a mode of respectively downloading the video encoding data and the audio encoding data to the client. After the video coding data and the audio coding data are downloaded, the client side combines and packages the video coding data and the audio coding data through the existing data packaging method to obtain a video transcoding file. For example, video encoding data and audio encoding data are converted into data segments, the data segments are converted into data packets or datagrams, the data packets or datagrams are converted into frames, and the frames are finally converted into bit streams, thereby completing the merging and encapsulating process.
By downloading the video coding data and the audio coding data to the client respectively, the situation that downloading fails due to the fact that breakpoints occur in the process of downloading the full coding data at one time is avoided, the data volume of single downloading is reduced, and the success rate of downloading the coding data by the browser is improved.
According to the technical scheme of the embodiment, the browser in the client decodes the target video file to be transcoded to obtain the original data, and the browser encodes the original data to obtain the encoded data, so that the effect that the browser independently transcodes the video file is achieved, transcoding support of the server does not need to be called, and transcoding performance and efficiency of the browser are greatly improved.
On the basis of the foregoing embodiment, optionally, "encoding the original data by the browser to obtain encoded data" in S101 includes:
according to the target parameters to be transcoded, encoding the original data through the browser to obtain encoded data; wherein the target parameters include at least one of: resolution, frame rate, and data format.
The target parameters are preset by a user, the resolution includes but is not limited to "720 p", "1080 p", and "2 k", the frame rate includes but is not limited to "30 Hz", "60 Hz", and "90 Hz", and the data format includes but is not limited to "mp 4", "avi", and "flv".
For example, assume that the target parameter is "resolution: 1080p "," frame rate: 60Hz "and" data Format: mp4 ″, the browser adjusts the encoding parameters involved in the encoding process according to the target parameters, so that the resolution of the video transcoding file corresponding to the finally obtained encoded data is 1080p, the frame rate is 60Hz, and the data format is mp 4.
