Description
Technical Field
The present application relates to the field of video network transmission technologies, and in particular, to a method, an apparatus, a device, and a computer-readable storage medium for transmitting video images.
Background
A Virtual Desktop Infrastructure (VDI) is a remote dynamic access technology that hosts and manages all Desktop Virtual machines in a data center in a unified manner, thereby supporting an enterprise level to implement a Desktop system, and enabling a user to access data resources on a network at any place and at any time through any device.
In order to enable a user to obtain a full PC usage experience, as in the remote desktop connection technology, in the virtual desktop technology, a data center server needs to send desktop Content (Screen Content), i.e., digital video images in units of pixels, to a client for the user to log in. At present, in the video network transmission process, a hard coding method is commonly used to encode video image data into a code stream and then transmit the code stream, and the video image is restored and displayed at a receiving end through hard decoding and rendering. The hard coding method is a method for coding images by adopting a video hardware coder, so that CPU hardware resources are not occupied, and the speed is greatly improved.
However, a general video hardware encoder supports only image data in YUV420 format. YUV is a color coding method that occupies less bandwidth, where Y is a luminance, i.e., grayscale signal; u and V are chrominance signals, which are used to describe the color and saturation of the image. In the YUV420 format, one U data and one V data are shared every 4 pixels, and one Y data is provided for each pixel. Compared to YUV444 format (each pixel has one Y data, one U data, and one V data) or RGB format (each pixel has one R data, one G data, and one B data), the image data in YUV420 format loses 3/4 chrominance information, thereby causing severe color deviation and picture blurring in the picture of the remote/virtual desktop.
Therefore, what kind of video image transmission technology is adopted to fully utilize the advantages of hard-coding and hard-decoding speed and ensure the picture quality of the video images in the remote/virtual desktop is a technical problem to be solved urgently by those skilled in the art.

Detailed Description
The core of the application is to provide a video image transmission method, a video image transmission device, video image transmission equipment and a computer readable storage medium, so that the picture quality of video images in a remote/virtual desktop is effectively guaranteed while the advantages of hard-coding and hard-decoding speed are fully utilized.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a video image transmission method applied to a video image sending device, and mainly includes the following steps:
step 11: raw color data of a video image of a remote desktop/virtual desktop is obtained.
Specifically, in order to effectively guarantee the image quality and simultaneously use a video hardware encoder only supporting YUV 420-format data, in the video image transmission method provided by the present application, image color data in other high-image-quality formats are used as YUV 420-format data to be hard-coded for transmission, and then the data receiving end restores the image color data in the original format according to the sequence (i.e. the recombination mode) when the image color data in the original format is input into the video hardware encoder, and the image color data in the original format is obtained again, so as to achieve the purpose of image transmission.
The image color data in the format with high picture quality is original color data, and as a preferred embodiment, the image color data may be YUV444 format data or RGB format data.
As mentioned above, YUV444 format and YUV420 format are also one of YUV formats, and their data includes Y, U and V channel data. In contrast, in YUV444 format data, each pixel corresponds to one Y data, one U data, and one V data; in YUV420 format data, each pixel corresponds to one Y data, but each 4 pixels corresponds to one U data and one V data. Therefore, the YUV444 format data in units of 4 pixels includes 12 data in total, and the YUV420 format data includes 6 data in total. That is, the data amount of YUV444 format data is 2 times as large as that of YUV420 format data for an image of the same pixel size.
In fact, it will be understood by those skilled in the art that, whatever the format of the data, there is no difference in the way it is stored (YUV format data typically stores Y, U and V data in columns, respectively), and the difference between the so-called "formats" is actually the difference in the amount of data and the meaning of the data representation (i.e. the data representing which channel of which pixel point it represents). For example, for an image with a pixel size of 10 × 10, the total amount of data of the color data in YUV444 format is 300, and 100 pieces of Y data, 100 pieces of U data, and 100 pieces of V data are respectively; and the total amount of data of the color data in YUV420 format is 150, wherein there are 100Y data, 25U data, and 25V data.
Therefore, even the color data in YUV444 format can be encoded by a video hardware encoder supporting YUV420 format data, but the video hardware encoder will automatically regard the input data as YUV420 format data, namely, consider that Y, U and V data are still in a ratio of 4:1: 1. Therefore, as long as the user can clearly understand the meaning of each data representation input into the video hardware encoder, the original format image color data can be restored after decoding.
As for the RGB format data, it is similar to YUV444 format data, one R data, one G data, and one B data per pixel, and can be converted with YUV444 format data according to a correlation calculation formula. The related content can refer to YUV444 format data, and is not described here.
Step 12: recombining the original color data into a preset number of recombined color data according to a preset recombination mode; the data volume of each recombined color data conforms to the data volume characteristic of YUV420 format data.
According to the foregoing, in order to clearly grasp the representation meaning of each data when the original color data is input to the video hardware encoder for encoding, in the video image transmission method provided by the application, after the original image data is obtained, the original image data is recombined according to a preset recombination mode, so that recombined color data is obtained. The preset reorganization mode is intended to grasp the representation meaning of each data in the reorganized color data, that is, the data represents which type of channel data of which pixel point. Since the data can be restored no matter how the data is encoded as long as the representation meaning of each data can be grasped, the preset reorganization mode can be any mode preset by a user. Of course, how many recombined color data are specifically recombined may also be set by the user in advance.
For example, still taking an image with a pixel size of 10 × 10 as an example, 300 pieces of YUV444 format data may be reassembled into 1 piece of YUV420 format data: wherein, by controlling the order of data input to the video hardware encoder, 100Y data and 100U data in the original image data can be regarded as 200Y data of the recombined color data, the first 50V data in the original image data can be regarded as 50U data of the recombined color data, and the last 50V data in the original image data can be regarded as 50V data of the recombined color data; alternatively, it is also possible to use both 100U data and 100V data in the original image data as 200Y data of the recombined color data, the first 50Y data in the original image data as 50U data of the recombined color data, and the last 50Y data in the original image data as 50V data of the recombined color data.
Of course, the 300 YUV444 format data may also be recombined into 2 pieces of YUV420 format data, for example, 100Y data in the original image data may be regarded as 100Y data of the first piece of recombined color data, 25U data in the original image data may be regarded as 25U data of the first piece of recombined color data, and the other 25U data in the original image data may be regarded as 25V data of the first piece of recombined color data; the 100V data in the original image data are regarded as the 100Y data of the second recombined color data, the other 25U data in the original image data are regarded as the 25U data of the second recombined color data, and the last 25U data in the original image data are regarded as the 25V data of the second recombined color data.
Of course, there may be many other combinations similar to the above examples, and those skilled in the art can select and set the combinations according to the practical application, and the present application is not limited thereto. It should be noted that, since the YUV444 format data is in a minimum unit of 4 pixels, the data amount of each piece of YUV444 format data should be a multiple of 6. Therefore, when data reorganization is performed, the data volume of each reorganized color data obtained through reorganization is ensured to be in accordance with the data volume characteristics of the YUV420 format data.
It should be noted that the reassembly referred to herein is only to change the data structure of the reassembled color data, and thus to adjust the order of the data input to the video hardware encoder, and does not change any data size. Of course, those skilled in the art may also store the recombined color data obtained by recombination for inputting to a video hardware encoder.
Step 13: and inputting each recombined color data as YUV420 format data into each video hardware encoder for encoding so as to obtain encoded code streams.
As described above, the number of copies of the recombined color data can be set at the will of the user. Each recombined color data can correspond to a video hardware encoder so as to encode the recombined color data to obtain a code stream. It is easy to understand that the simultaneous encoding by using multiple video hardware encoders can further increase the data processing speed and efficiency. The encoded code stream may specifically adopt a standard RTMP or other transmission protocol for transmission, so that the video image receiving device receives and displays the code stream.
Step 14: respectively sending each code stream to video image receiving equipment; and the video image receiving equipment respectively inputs the code streams into the video hardware decoders for decoding so as to obtain the recombined color data, and restores the recombined color data into original color data according to a preset recombination mode.
Specifically, after the video image receiving device receives each code stream, the video image receiving device may decode each code stream by using a video hardware decoder to obtain recombined color data, and further may restore the recombined original color data according to the preset recombination mode to obtain original color data, so as to render a video image of the remote desktop/virtual desktop corresponding to the transmitted original color data to be displayed on a screen.
Therefore, in the video image transmission method provided by the embodiment of the present application, by recombining the original color data in the high picture quality format according to the preset recombination manner, the representation meaning of each recombined color data input to the video hardware encoder for encoding can be clearly grasped, and after the video image is received and decoded, decoding can be performed according to the preset recombination manner to obtain the original image data. The method and the device can utilize the video hardware encoder to finish the transmission of the color data with high picture quality format, thereby improving the processing efficiency and ensuring the picture quality.
The video image transmission method provided by the application is based on the embodiment as follows:
as a preferred embodiment, the predetermined number is 2.
Specifically, as described above, the data amount of YUV444 format data or RGB format data is 2 times that of YUV420 format data for the same pixel size image. Therefore, in order to facilitate data reorganization, the preset number may be specifically set to 2, that is, the original color data is reorganized into 2 reorganized color data.
As a preferred embodiment, the recombining the original color data into a predetermined number of recombined color data according to a predetermined recombining manner includes:
and sequentially extracting the original color data according to the storage sequence to form a preset number of recombined color data.
Specifically, in order to simplify the data reassembly operation and avoid unnecessary data addressing, the data structure of the original color data may be retained as much as possible, that is, the entire data is selected and the original data sequence is retained to form the reassembled color data. Therefore, it is preferable to sequentially extract the original color data in the order of storage of the data itself to constitute the reformed color data.
As a preferred embodiment, both the video hardware encoder and the video hardware decoder support the h.264 digital video coding standard.
In particular, h.264 is a new generation digital video compression format following MPEG4, commonly proposed by the international organization for standardization (ISO) and the International Telecommunications Union (ITU). The H264 standard has higher coding efficiency compared with other standards such as H.263 and the like, uses a mixed coding structure of differential coding by adopting DCT (discrete cosine transform) transform coding and DPCM (differential code), and also adds new coding modes such as multi-mode motion estimation, intra-frame prediction, multi-frame prediction, variable length coding based on contents, 4 x 4 two-dimensional integer transform and the like, thereby improving the coding efficiency and saving more than 50 percent of code rate on average; also, h.264 can provide high quality image transmission over a lower bandwidth; in addition, the h.264 standard has high network adaptability, and can operate in a low-latency mode for real-time communication applications, and can also operate in a video storage or video streaming server without latency.
