Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method of video redirection, it being noted that the steps illustrated in the flowchart of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than here.
Fig. 1 is a flow chart of a method of video redirection according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S102, intercepting the audio and video to be played before the video player in the server decodes and plays the audio and video to be played, wherein the audio and video to be played is the video which is requested to be played by the client to the server through the remote desktop;
the video player is of various types, and in an optional implementation manner of the embodiment of the present invention, the video player is selected as a VLC player. Besides VLC players, other video players are also included, and the type of specific video player is not specifically limited in the embodiment of the present invention.
Step S104, processing the video player so that the processed video player does not generate alarm information after the audio/video to be played is intercepted;
and step S106, after the video player is processed, the audio and video to be played are sent to the client, wherein after the client receives the audio and video to be played, the client synthesizes the audio and video to be played and the picture of the remote desktop, and performs local decoding operation on the synthesized picture so as to display the synthesized picture on a display interface of the client.
It should be noted that, in the embodiment of the present invention, after the client is connected to the remote desktop of the server, the client may initiate a video playing request to the server, and then the server loads the audio and video file to be played through the video player and transmits the video data stream of the video file to the client for processing. The above process may be understood as a video redirection process.
In the embodiment of the invention, the audio and video to be played are intercepted before the video player in the server decodes and plays the audio and video to be played, then the video player is processed, so that the processed player does not generate alarm information after the audio and video to be played are intercepted, and finally the audio and video to be played are sent to the client for displaying after the video player is processed. In the embodiment of the invention, the mode of processing the audio and video at the client side is adopted, so that the aim of reducing the consumption of the server is achieved, the technical problem of poor performance when the server transmits the audio and video data to the client side through the remote desktop in the prior art is solved, and the technical effect of improving the playing effect of the audio and video is realized.
In an optional implementation manner of the embodiment of the present invention, processing the video player includes the following steps:
step S1041, sending playing information to a video player, where the playing information is used to instruct the video player to play a preset video to replace the video player to play the audio and video to be played, each frame of the preset video is a color indicated by a key color, and a color with a color value of #00000F in a desktop picture of the client is set as a transparent color, where the key color is a color selected in advance.
Under normal conditions, the audio and video to be played requested by the client to the server is played in the video player at the server side, and when the server intercepts the audio and video to be played before the audio and video to be played is played by the video player, the video player cannot normally play the audio and video to be played, and at the moment, the video player reports an error. In order to enable the video player not to decode the audio/video to be played, but the inside of the video player can also be played as a current playing state without making an error, at this time, the server needs to send playing information to the video player, where the playing information is used to indicate that a starting picture of the audio/video to be played by the video player is a preset picture, and further inform the video player that all pictures after the starting picture of the audio/video to be played are the same as the starting picture. The color of the preset picture is the color indicated by the key color, and the color with the color value of #00000F in the desktop picture of the client is set to be transparent, wherein the key color is a pre-selected color.
After the processing, the video player can play the audio and video to be played without error.
In another optional implementation manner of the embodiment of the present invention, sending the audio/video to be played to the client for decoding and playing includes the following steps:
step S11, determining the client to which the video stream and the audio stream of the audio and video to be played at the current moment belong;
and step S12, sending the video stream and the audio stream at the current moment to the affiliated client for decoding and playing.
In the embodiment of the invention, when the user is connected with the remote desktop of the server through the client, a plurality of users can simultaneously share the same operating system of the same host, wherein the host is the server. That is, multiple users can simultaneously request the same video file from the server for playback. In this case, the server needs to determine to which client the video stream and the audio stream of the audio and video to be played at the current time belong, that is, to which user the video stream and the audio stream of the audio and video to be played at the current time belong. After determining the users (i.e., clients) to which the current audio stream and video stream belong, the current audio stream and video stream can be sent to the users (i.e., clients) to which the current audio stream and video stream belong for decoding and playing.
In summary, in the embodiment of the present invention, after the video redirection technology is used, actions that consume a CPU very much, such as composition, screenshot, and video compression, on a host (that is, a server) are omitted, and CPU occupation when a video player plays a video in the server itself is even omitted. That is, if the user is just playing video, then ideally (i.e., without regard to other software and rendering of the desktop itself), the CPU footprint of the host (i.e., server) would be close to 0, which would save hardware performance cost significantly.
Fig. 2 is a flow chart of another method of video redirection according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
step S202, obtaining the audio and video to be played sent by the server,
the to-be-played audio and video is obtained by the server in an intercepting mode before the video player decodes and plays the to-be-played audio and video, the to-be-played audio and video is a video which is requested to be played by the client to the server through the remote desktop, and the server processes the video player before sending the to-be-played audio and video to the client, so that the processed video player does not generate alarm information after the to-be-played audio and video is intercepted.
And S204, synthesizing the audio/video to be played and the picture of the remote desktop to obtain a synthesized result, and performing local decoding operation on the synthesized picture so as to display the synthesized picture on a display interface of the client.
In the embodiment of the invention, the audio and video to be played are intercepted before the video player in the server decodes and plays the audio and video to be played, then the video player is processed, so that the processed player does not generate alarm information after the audio and video to be played are intercepted, and finally the audio and video to be played are sent to the client for displaying after the video player is processed. In the embodiment of the invention, the mode of processing the audio and video at the client side is adopted, so that the aim of reducing the consumption of the server is achieved, the technical problem of poor performance when the server transmits the audio and video data to the client side through the remote desktop in the prior art is solved, and the technical effect of improving the playing effect of the audio and video is realized.
In an optional implementation manner of the embodiment of the present invention, synthesizing the to-be-played audio/video and the picture of the remote desktop to obtain a synthesis result includes the following steps:
step S2041, decoding the audio and video to be played;
and step S2042, while decoding the audio/video to be played, synthesizing the decoded audio/video to be played and the picture of the remote desktop in real time, and displaying the synthesis result on a display interface in real time.
In the embodiment of the invention, after the client acquires the audio/video to be played, the client decodes the audio/video to be played, and simultaneously synthesizes the decoded audio/video to be played and the picture of the remote desktop in real time.
The method for synthesizing the decoded audio/video to be played and the picture of the remote desktop in real time comprises the following steps:
step S21, acquiring pictures of a plurality of windows contained in the remote desktop;
step S22, packaging the pictures of the windows in real time, and obtaining the pictures of the remote desktop after packaging;
and step S23, synthesizing the decoded audio/video to be played with the picture of the remote desktop obtained after packaging.
In the embodiment of the invention, the remote desktop may include a plurality of windows, and at this time, the pictures of the plurality of windows included in the remote desktop can be obtained in real time; and then packaging the obtained pictures of the windows in real time to obtain the picture of the remote desktop at the current moment. And finally, synthesizing the synthesized picture of the remote desktop with the decoded audio/video to be played to obtain a synthesis result, and displaying the synthesis result in the current client.
As can be seen from the above description, in the embodiment of the present invention, after the video redirection technology is used, the audio and video to be played is not decoded and played by the host (i.e., the server), but the video data is intercepted before the video player plays the video, and then the video data of the audio and video to be played is directly transmitted to the client from the host intact; then, the client decodes and plays the audio and video file, and the audio and video file is synthesized with the user desktop and then displayed on the screen.
After the video redirection technology is used, actions which consume a CPU greatly, such as composition, screenshot, video suppression and the like on a host computer, are omitted, and CPU occupation when a video player plays a video is even omitted. That is, if the user is just playing video, then ideally (i.e., without regard to other software and rendering of the desktop itself), the CPU footprint of the host would be close to 0, which would save hardware performance costs significantly.
