Method and apparatus for video playing processing and television

1. A method for video playing processing performed by a video rendering device, comprising:

receiving a preview operation for a video in a form of a long press on a predetermined key on a remote control unit while the video is being played in a playing window of the video rendering device by a first thread running in the video rendering device, wherein the preview operation is used for indicating a fast forward operation or a fast backward operation on the video;

upon detecting an end of the long press:

initiating a second thread independent of the first thread in the video rendering device, determining a time length for the long press, and determining a video playing position of the preview operation based on a current video position for the video being played and the time length for the long press;

determining a playing resource corresponding to the video;

downloading, by the second thread, a video clip corresponding to the video playing position, according to the video playing position in the playing resource;

determining, by the second thread, at least one frame image decoded from the video clip; and

displaying, by the second thread, the at least one frame image in a preview window of the video rendering device, and displaying the video in the playing window by the first thread without interruption, wherein the playing window in an OSD layer is located below the preview window in the OSD layer; and

when the preview window is selected, switching contents being displayed in the playing window obtained by the first thread to the at least one frame image obtained by the second thread after decoding, and closing the first thread and the preview window.

2. The method of claim 1 , wherein the determining, by the second thread, at least one frame image decoded from the video clip comprises:

reading, after a first decoder decodes at least one frame image of the video clip, the at least one frame image by the second thread, wherein the first decoder is different from a second decoder and is used for decoding an image of the video being played by the first thread.

3. The method of claim 1 , wherein the video clip is a minimum video clip.

4. The method of claim 1 , wherein the displaying the at least one frame image in the preview window comprises:

displaying a thumbnail of the at least one frame image in the preview window.

5. The method of claim 1 , wherein a layer on the preview window includes an operating focus.

6. The method of claim 1 , wherein the determining, by the second thread, at least one frame image decoded from the video clip comprises:

reading, after a first decoding thread decodes at least one frame image of the video clip, the at least one frame image by the second thread, wherein the first decoding thread is different from a second decoding thread and is used for decoding an image of the video being played by the first thread.

7. The method of claim 1 , wherein the playing resource is an address of the video in network, or a local address where the video is stored in the video rendering device.

8. An apparatus for video playing processing, comprising: a memory used for storing instructions; a processor coupled to the memory and configured to execute the instructions stored in the memory, wherein the processor is configured to:

receive a preview operation for a video in a form of a long press on a predetermined key on a remote control unit while the video is being played in a playing window of the apparatus by a first thread running in the apparatus, wherein the preview operation is used for indicating a fast forward operation or a fast backward operation on the video;

upon detecting an end of the long press:

initiate a second thread independent of the first thread in the apparatus, determine a time length for the long press, and determine a video playing position of the preview operation based on a current video position for the video being played and the time length for the long press;

determine a playing resource corresponding to the video;

download, by the second thread, a video clip corresponding to the video playing position, according to the video playing position in the playing resource;

determine, by the second thread, at least one frame image decoded from the video clip; and

display, by the second thread, the at least one frame image in a preview window of the apparatus, and display the video in the playing window by the first thread without interruption, wherein the playing window in an OSD layer is located below the preview window in the OSD layer; and

when the preview window is selected, switching contents being displayed in the playing window obtained by the first thread to the at least one frame image obtained by the second thread after decoding, and closing the first thread and the preview window.

9. The apparatus of claim 8 , wherein the processor is further configured to:

read the at least one frame image by the second thread, after a first decoder decodes the at least one frame image of the video clip, wherein the first decoder is different from a second decoder and is used for decoding an image of the video being played by the first thread.

10. The apparatus of claim 8 , wherein the processor is further configured to:

displaying a thumbnail of the at least one frame image in the preview window.

11. The apparatus of claim 8 , wherein a layer on the preview window includes an operating focus.

12. The apparatus of claim 8 , wherein the processor is further configured for:

reading the at least one frame image by the second thread, after a first decoding thread decodes the at least one frame image of the video clip, wherein the first decoding thread is different from a second decoding thread and is used for decoding an image of the video being played by the first thread.

13. The apparatus of claim 8 , wherein the playing resource is an address of the video in network, or a local address where the video is stored in the apparatus.

14. A television, comprising:

a memory, a processor, a communication interface and a display screen; wherein the memory is configured for storing instructions, wherein the communication interface is configured for receiving a preview operation for a video in a form of a long press on a predetermined key on a remote control unit while the video is being played in a playing window on the display screen by a first thread running in the television, wherein the preview operation is used for indicating a fast forward operation or a fast backward operation on the video, and wherein the processor, when executing the instructions, is configured for:

upon detecting an end of the long press:

initiating a second thread independent of the first thread in the television;

determining a time length for the long press;

determining a video playing position of the preview operation based on a current video position for the video being played and the time length for the long press;

determining a playing resource corresponding to the video;

downloading, by the second thread, a video clip corresponding to the video playing position, according to the video playing position in the playing resource;

determining, by the second thread, at least one frame image decoded from the video clip; and

displaying, by the second thread, the at least one frame image in a preview window on the display screen, and displaying the video in the playing window by the first thread without interruption, wherein the playing window in an OSD layer is located below the preview window in the OSD layer; and

when the preview window is selected, switching contents being displayed in the playing window obtained by the first thread to the at least one frame image obtained by the second thread after decoding, and closing the first thread and the preview window.
