In addition, in the above description, data is transmitted between the decoder and the browser based on the real physical address, that is, the decoder and the browser can directly access the real physical memory to access the data, which is compared with the prior art that data is transmitted between the decoder and the browser based on the virtual address, but data copy and dump are inevitably involved, so that the performance of the whole video playing system can be effectively improved.
The following embodiments are shown to explain the video playing method proposed in the present application in detail as follows:
in order to facilitate understanding of the present application, a system architecture to which the video playing method proposed by the present application is applied will be described first.
Please refer to fig. 1, which is a schematic diagram of a system architecture of an application of the video playing method provided by the present application. Fig. 1 includes a video playback system 100, where the video playback system 100 includes at least a decoder 110 and a browser 120.
In this embodiment of the present application, the browser 120 sends an original video stream to the decoder 110, and after the decoder 110 receives the video stream, the method provided in the present application may be used to continuously decode each video frame in the video stream, and store a video image obtained by decoding into a memory space corresponding to a specified physical address; meanwhile, the browser 120 may use the method provided in the present application to continuously obtain the video image from the memory space, load OpenGL (Open Graphics Library) (not shown in fig. 1) to render the obtained video image, and play the rendered video image.
As to how the decoder 110 and the browser 120 implement the above-mentioned processes by using the method provided in the present application, refer to the following description, and will not be described in detail herein.
It should be noted that, in the embodiment of the present application, since the decoder 110 stores the decoded video image into the memory space, and then the browser obtains the video image from the memory space and renders the video image, the rendering tool, for example OpenGL, may be modified in advance, so that the rendering tool has a function of obtaining the video image from the memory space and rendering the video image. Specifically, how to modify the rendering tool may be implemented by a method in the prior art, for example, by adding a specific interface to the rendering tool, which is not described herein again.
As follows, the following embodiments are shown to explain the video playing method provided by the present application in detail:
the first embodiment,
Referring to fig. 2, a flowchart of an embodiment of a video playing method provided in an exemplary embodiment of the present application may be applied to the video playing system 100 illustrated in fig. 1, and includes the following steps:
step 201: after receiving the video stream, the decoder decodes each video frame in the video stream in sequence, stores the video image obtained by decoding into a memory space corresponding to the specified physical address, and sends the physical address to the browser.
In this embodiment of the application, after receiving the video stream, the decoder 110 may sequentially decode each video frame in the video stream, and may store the decoded video image in the memory space corresponding to the specified physical address.
In an example, the decoder 110 performs data compression on the decoded video image, and stores the compressed video image in a memory space corresponding to a specified physical address. Through the processing, the data storage cost can be effectively reduced, and the performance of subsequent data transmission is improved.
In one example, the decoder 110 may perform data compression on the decoded video image based on the NV12 data format, i.e., convert the format of the decoded video image into the NV12 data format. In the NV12 data format, each 4Y components share one U component and one V component, that is, each pixel only needs to occupy 1.5 bytes for storage, for example, as shown in fig. 3, which is a storage diagram in the NV12 data format. Therefore, compared with the RGB data format in which each pixel needs to occupy 3 bytes for storage, the NV12 data format can save half of the memory space by converting the format of the decoded video image.
In the embodiment of the present application, after the decoder 110 stores the decoded video image in the memory space corresponding to the specified physical address, the physical address is sent to the browser 120.
Step 202: and after receiving the physical address, the browser writes the physical address into a preset cache region.
In this embodiment, a cache area is provided on the browser 120 side, and each time the browser 120 receives a physical address, the physical address may be written into the cache area.
In one example, the buffer may be implemented by using a plurality of buffer registers, for example, 8 buffers. In this example, each time the browser 120 receives a physical address, the physical address is written into an empty buffer.
In one example, the plurality of buffers may exist in the form of a list.
In another example, the plurality of buffers may exist in the form of a queue.
Step 203: the browser sequentially obtains the physical addresses from the cache region, obtains the video images from the memory space according to the obtained physical addresses, renders the obtained video images, and plays the rendered video images.
In this embodiment of the application, the browser 120 may sequentially obtain the physical addresses from the cache region, and each time a physical address is obtained, may obtain the video image from the memory space according to the obtained physical address, render the obtained video image, and play the rendered video image.
In addition, in this embodiment of the application, each time the browser 120 finishes rendering the video image, the currently acquired physical address, that is, the physical address corresponding to the video image, may be deleted from the cache region, so as to clean the cache region in real time.
It should be noted that, the sequence between step 201 and step 203 is merely an example, and in practical applications, there may be other achievable execution sequences, for example, step 202 and step 203 may be executed simultaneously, which is not limited in this application.
As can be seen from the above description, since the decoder stores the decoded video image into the memory space corresponding to the specified physical address and sends the physical address to the browser, the browser can directly obtain the video image from the memory space according to the physical address, and through this processing, data copying and transferring can be effectively avoided, thereby effectively improving the performance of the video playing system, further, since the browser puts the received physical address into the cache region, the browser can sequentially obtain the physical addresses from the cache region, further obtain the video image, and render the obtained video image, through this processing, the decoder can decode the video frame continuously, the browser can render the obtained video image continuously, thereby implementing parallel operation between the two processes of video image rendering and video frame decoding, the efficiency of video playing is improved.
The description of the first embodiment is completed.
In this embodiment of the application, ideally, the decoder 110 may continuously send the physical address to the browser 120, that is, the browser 120 may continuously write the physical address into the cache region, and meanwhile, the browser 120 may continuously obtain the physical address from the cache region, obtain the video image based on the obtained physical address, and perform rendering, thereby achieving complete parallelism between the browser 120 and the decoder 110.
However, in practical applications, a network may be poor, which may cause a decoding speed of the decoder 110 to be low, so that the number of physical addresses in the buffer area is insufficient, in this case, the browser 120 may repeatedly render the currently acquired video image and play the rendered video image, and at this time, a static frame phenomenon occurs in video playing; meanwhile, in practical applications, a situation that the rendering speed of the browser is slow may also occur, and in this situation, in order to avoid that the decoder 110 updates the data of the current frame in the memory space at the same time because the rendering of the current frame is not finished yet, and a memory "stepping on" phenomenon occurs, that is, a phenomenon of screen splash and screen flashing occurs in video rendering, the decoder 110 may continue to decode the next frame of data after the rendering of the current frame by the browser 120 is finished.
Based on the above description, in the embodiment of the present application, it is proposed that the decoder 110 and the browser 120 perform real-time adjustment based on the current decoding speed and rendering speed during the parallel operation process, so as to avoid the phenomena of insufficient physical addresses in the buffer area and "memory hit".
The following examples, continuing with the description of the method, are presented as follows:
example II,
Referring to fig. 4, a flowchart of an embodiment of a video playing method according to another exemplary embodiment of the present application is provided, where the embodiment may include the following steps based on the embodiment shown in fig. 2:
step 401: after receiving the video stream, the decoder decodes each video frame in the video stream in sequence, and stores the video image obtained by decoding into the memory space corresponding to the designated physical address.
Step 402: the decoder sends the physical address to the browser.
Step 403: and after receiving the physical address, the browser writes the physical address into a preset cache region.
Step 404: the browser sequentially obtains the physical addresses from the cache region, obtains the video images from the memory space according to the obtained physical addresses, renders the obtained video images, and plays the rendered video images.
For the detailed description of the steps 401 to 404, reference may be made to the related description in the first embodiment, and details are not repeated here.
Step 405: the browser judges whether the number of the physical addresses stored in the cache area is larger than or equal to a preset number threshold, if so, the browser returns to execute the step 404, and otherwise, the browser executes the step 406.
Step 406: rendering the currently acquired video image again, and playing the rendered video image; step 405 continues until the playback is completed.
In this embodiment of the application, after the browser 120 finishes rendering the current frame, it may determine whether the number of physical addresses stored in the cache region is greater than or equal to a preset number threshold, for example, 3, if so, it may be considered that the number of physical addresses in the cache region is sufficient, and then return to execute step 404, that is, continue to obtain a next frame of video image and render the next frame of video image; otherwise, the number of the physical addresses in the buffer area is considered to be insufficient, and step 406 is executed, that is, the current frame is rendered repeatedly, the rendered video image is played, and at this time, a static frame appears in the video playing.
The number threshold may be summarized by those skilled in the art according to the conventional period and timing relationship of browser rendering, and as to how to obtain the number threshold, the description of the present application is omitted.
As can be seen from the above embodiment, after the current frame is rendered by the browser, it is determined whether the number of physical addresses stored in the cache area is greater than or equal to a preset number threshold, and if so, the browser continues to acquire and render a next frame of video image; otherwise, the browser repeatedly renders the current frame, so that the phenomena of insufficient physical addresses and memory treading in the cache region can be effectively avoided.
