Detailed Description

To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

The concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

A flowchart of a method of video compositing according to the present embodiment is illustrated in fig. 25. Referring to fig. 25, in order to implement the picture preview and obtain the specified video file, the video recording method provided in the embodiment of the present invention further includes:

and S17, receiving a recording ending instruction generated when the control button is triggered, wherein the state of the control button triggered comprises a triggered state when the countdown is ended and a triggered state when the control button is clicked when the countdown is not ended.

And S18, responding to the recording ending instruction, synthesizing the specified video material, the specified lyrics and the picture shot by the camera to obtain the specified video file.

And the user clicks a control button displayed in the recording interface, or the countdown displayed on the control button is finished, and then the current video recording process is finished. The conditions of the generation of the recording ending instruction generated by the control button comprise the generation when a user actively clicks the control button and the automatic generation when the countdown is ended.

And the display equipment finishes the recording process according to the recording finishing instruction, and simultaneously synthesizes the recorded specified video material, the specified lyrics and the picture shot by the camera to obtain the specified video file. For video synthesis, a renderer (OpenGLRender), a view previewer (glfaceview) and a media encoder (MediaCodec) are arranged in the display device, pictures, lyrics and video materials shot by a camera are synthesized into a same frame of picture by the renderer, the picture frame synthesized by the renderer is converted into byte data by the view previewer, a final image effect is displayed, and finally the byte data converted from the synthesized image are encoded by the media encoder to obtain a video file in an mp4 format.

Fig. 26 is a flowchart illustrating a method of composing a specified video file according to the present embodiment; fig. 27 is a diagram exemplarily showing a data flow for synthesizing a specified video file according to the present embodiment. Specifically, referring to fig. 26 and 27, the process of the display device synthesizing a specified video material, specified lyrics, and a picture taken by a camera to obtain a specified video file in response to the recording ending instruction includes:

and S181, responding to the recording ending instruction, calling a renderer, rendering and synthesizing the appointed video material and the appointed lyric corresponding to each frame of video picture and the picture shot by the camera to obtain a synthesized image.

In the process of executing video recording, the camera sends the shot pictures to the renderer along with the playing of the specified video content, the display equipment sends the video material and the specified lyrics corresponding to each moment or each frame of picture to the renderer, and the renderer renders and synthesizes the specified video material, the specified lyrics and the pictures shot by the camera to obtain a synthesized image. The composite image is a video picture taking a frame as a unit, namely, when the camera shoots one frame of picture, the display equipment sends the frame of picture, the corresponding video material and the lyrics to the renderer for rendering and synthesis, and the obtained picture frame is previewed in real time and displayed in the previewing picture.

The renderer is internally provided with an effect rendering helper (effect render helper), and the display device calls a texture processing (processTexture) method of the effect rendering helper (effect render helper) to synthesize the effect rendering helper and the lyrics to be displayed at the current time so as to draw the effect on the original picture of the camera and the lyrics to be displayed at the current time.

After the recording is finished, the display equipment calls the renderer to render and synthesize each frame of picture shot by the camera with the corresponding specified video material and the corresponding specified lyrics according to the recording finishing instruction, and a plurality of synthesized pictures can be obtained.

S182, calling a view previewer to convert the synthetic image into byte type data;

a view previewer (GLSurfaceView) has a frame renderer built therein, and executes a frame rendering (onDrawFrame) method. After the camera previewing is started, the original image shot by each frame of camera is called back in a frame drawing (onDrawFrame) method of a view previewer (GLSurfaceView).

The callback refers to a monitoring mechanism set in the display device and used for data monitoring. After the camera shoots a frame of picture, the monitoring mechanism monitors a new shot picture, and the new shot picture is obtained by the renderer and rendered and synthesized, so that real-time rendering and synthesis of each frame of picture shot by the camera are realized. Then, each composite image is converted into byte type data by a frame renderer, and an image is previewed and displayed on a preview screen.

The frame rendering method provides a cache output (dispatch output buffer) method of converting a Texture (Texture) of a synthesized image in a renderer (OpenGLRender) into byte type data, such as byte [ ] type data. The displayed picture of each frame corresponds to a group of byte [ ] information.

And S183, calling a media encoder to encode the byte type data to obtain the specified video file.

The media encoder may encode video and audio simultaneously, and thus, when encoding, the media encoder creates the video encoder and the audio encoder simultaneously, calls the create encoding type method, creates the video type "video/avc" and the audio type "audio/mp 4 a-lam", respectively.

And then appointing information such as frame rate, code rate, color format and the like of the video, and appointing information such as sampling rate, sound channel, sampling format and the like of the audio. And then calling a media mixer (MediaMuxer), creating a media mixing object, and specifying a file storage path and a file format for mixing and encoding the video and the audio into a video file.

When a video file is mixed, video and audio are two encoding processes, so two sub-threads need to be created to respectively perform encoding of the video and the audio. The source of the audio includes sound at the time of playback of the specified video content and sound collected by a MIC provided in the display apparatus.

When recording video, the media encoder registers the monitor first, and receives byte [ ] type data converted by the frame renderer. When video coding is carried out, after a media encoder receives byte [ ] data, the video encoder calls an input buffer (dequeuinputbuffer) method of the media encoder (MediaCodec) to apply for buffer, and the byte [ ] type data is transmitted to a buffer area of the application. After the encoding process is executed, a buffer output method (dequeuoutputbuffer) method of a media encoder (MediaCodec) is called to obtain encoded data.

And judging whether the data is legal or not according to the buffer data (bufferInfo) information of the encoded data. If legal, the write sample data (writesampleData) method of the media compositor (MediaMuxer) is called, and the encoded video data is written into the video track, otherwise the frame data is discarded.

Also, in audio coding, the same encoding process may be used as for video coding samples. However, since the audio data source is different from the video source, the audio data source may be from external sound received by the television MIC, or may be sound played by the television (sound of the specified video content being played). Therefore, when audio encoding is performed, the audio encoder needs to cyclically obtain samples to obtain original audio data, and the encoded original audio data is written into an audio track by calling a sample data writing (writesampedata) method of a media mixer (mediamixer).

And finally, after the video coding and the audio coding are respectively finished, carrying out mixed coding on the obtained video track and the audio track again to obtain a video file. Specifically, a media compositor (mediamixer) is called, the video track and the audio track obtained in the foregoing are taken as media compositor objects, and the video track and the audio track are mixedly encoded into a specified video file.

Fig. 28 is a diagram illustrating a recording completion interface according to the present embodiment. Referring to fig. 28, the display device performs encoding while performing video recording, and when the user clicks a control button (a confirmation key) on the recording interface or the video recording time is up, the recording flag is reset, the encoding cycle is skipped, the video recording and the file storage are completed, and the display device switches the recording interface to a recording completion interface.

In the recording completion interface, the specified video file which is just recorded is played in a circulating mode, the specified video file is uploaded to a server, the server generates a corresponding link address according to the specified video file, two-dimension code information is generated according to the link address and sent to display equipment, and the two-dimension code information is displayed on the recording completion interface through the display equipment. And the two-dimension code information is used for downloading the video to the mobile phone after the mobile phone of the user scans the code, or synchronizing the video to other equipment.

The recording completion interface can also display a sharing to friend circle interface, a saving to album interface, a re-recording interface, a singing whole head interface and the like. The sharing to friend circle interface is used for providing a function of sharing the specified video file to a friend circle for a user; the 'save to album' interface is used for providing a function for storing files to the local for a user; the re-recording interface is used for returning to the application main interface for re-recording; the re-recording interface is used for jumping to a K song interface for a user to enter a K song function.
