Abstract

Provided a method and device for playing and processing a video based on a virtual desktop. The method comprises: a terminal receives a original code stream of a video file to be played currently, wherein the original code stream is sent to the terminal by a virtual desktop system after the virtual desktop acquires the original code stream; and the terminal plays the video file according to the original code stream. The disclosure avoids or reduces the occupation of Central Processing Unit (CPU) resources of a virtual machine host, and achieves smooth playback of video files.

Claims

1. A method for playing a video based on a virtual desktop, comprising:

receiving, by a terminal, an original code stream of a video file to be played currently, wherein the original code stream is sent to the terminal by a virtual desktop system after the virtual desktop acquires the original code stream; and

playing, by the terminal, the video file according to the original code stream.

2. A device for playing a video based on a virtual desktop, comprising:

a receiving component, configured to receive an original code stream of a video file to be played currently, wherein the original code stream is sent to a terminal by a virtual desktop system after the virtual desktop acquires the original code stream; and

a playing component, configured to play the video file according to the original code stream.

3. A method for processing a video based on a virtual desktop, comprising:

sending, by a virtual desktop system, an original code stream of a video file to be played currently to a video format converter for format conversion;

sending, by the virtual desktop system, the converted code stream to a terminal for video playing.

4. The method according to claim 3, wherein before the virtual desktop system sends the original code stream of the video file to be played currently to the video format converter for format conversion, the method further comprises:

acquiring, by the virtual desktop system, the original code stream from the video file.

5. The method according to claim 3, wherein the video format converter is set on a virtual server in advance.

15. The method according to claim 4, wherein the video format converter is set on a virtual server in advance.

6. A device for processing a video based on a virtual desktop, comprising:

a first sending component, configured to send an original code stream of a video file to be played currently to a video format converter for format conversion, wherein the video format converter is set on a virtual server in advance; and

a second sending component, configured to send the converted code stream to a terminal for video playing.

7. A method for processing a video based on a virtual desktop, comprising:

scanning, by a virtual desktop system, a video file on the virtual desktop to obtain first graphic information for describing a change area of the video file;

sending, by the virtual desktop system, the first graphic information to a format compressor for compression; and

sending, by the virtual desktop system, second graphic information obtained by compression to a terminal for video playing.

8. The method according to claim 7, wherein the first graphic information comprises:

information located in a Graphics Processing Unit (GPU).

9. A device for processing a video based on a virtual desktop, comprising:

a scanning component, configured to scan a video file on the virtual desktop to obtain first graphic information for describing a change area of the video file;

a first sending component, configured to send the first graphic information to a format compressor for compression; and

a second sending component, configured to send second graphic information obtained by compression to a terminal for video playing.

10. The device according to claim 9, wherein the first graphic information comprises:

information located in a Graphics Processing Unit (GPU).

11. A method for processing a video based on a virtual desktop, comprising:

scanning, by a virtual desktop system, a video file on the virtual desktop to obtain first graphic information for describing a change area of the video file;

sending, by the virtual desktop system, the first graphic information and a preset compression policy to a virtual server or a preset compressor for compression, wherein the preset compression policy is used for dynamically adjusting to different compression ratios based on different network bandwidths; and

sending, by the virtual desktop system, second graphic information obtained by compression to a terminal for video playing.

12. The method according to claim 11, wherein the preset compression policy comprises multiple different compression ratios, wherein a compression ratio is in proportion to a network bandwidth.

13. The method according to claim 11, wherein the first graphic information comprises:

information located in a Graphics Processing Unit (GPU).

16. The method according to claim 12, wherein the first graphic information comprises:

information located in a Graphics Processing Unit (GPU).

14. A device for processing a video based on a virtual desktop, comprising:

a scanning component, configured to scan a video file on the virtual desktop to obtain first graphic information for describing a change area of the video file;

a first sending component, configured to send the first graphic information and a preset compression policy to a virtual server or a preset compressor for compression, wherein the preset compression policy is used for dynamically adjusting to different compression ratios based on different network bandwidths; and

a second sending component, configured to send second graphic information obtained by compression to a terminal for video playing.
