Embodiment 1

[0037] This embodiment provides a processing method for rotating video during playback, which is used to rotate the video image being played during the video playback process using a computer video player, such as figure 1 As shown, the processing method specifically includes:

[0038] Step S101, setting a rotation processor in the filter link of playing video;

[0039] Step S102, using the rotation processor to perform rotation processing on the decoded video data in the playing video; during processing, the rotation processor performs rotation processing in units of one frame of original video data;

[0040] Step S103, outputting the video data obtained after the rotation processing to the renderer for rendering and then outputting and displaying.

[0041] In the above processing method, the rotation processing in step S102 is specifically:

[0042] Convert the decoded original image frame data to the RGB32 color space, and perform corresponding transformation processing o...

Embodiment 2

[0069] This embodiment provides a processing device for rotating video during playback, such as Figure 9 As shown, the processing device specifically includes:

[0070] detection unit, transfer unit and rotation processing unit;

[0071] Wherein, the detection control unit S301 is respectively connected with the transmission unit S302 and the rotation processing unit S303, and is used to detect whether to perform rotation processing on the video being played, if so, make the input video data enter the rotation processing unit for processing, if not, The input video data is directly transmitted to the renderer connected to the processing device through the transmission unit;

[0072] The transmission unit S302 is connected to the detection control unit S301, and is used to directly transmit the input video data to the renderer connected to the processing device;

[0073] The rotation processing unit S303 is connected with the detection control unit S301, and is used to rotat...

Embodiment 3

[0080] This embodiment provides a processing system for rotating video during playback, such as Figure 11 As shown, the processing system specifically includes:

[0081] A data separator S401, a video decoder S402, a rotation processing device S403, and a renderer S404; wherein, the rotation processing device S403 may adopt the rotation processing device given in Embodiment 2 above;

[0082] Wherein, the data separator S401 is connected with the video decoder S402, and is used to separate the video data from the input video file data, and output the video data to the video decoder S402;

[0083] The video decoder S402 is connected to the rotation processing device S403 for decoding the input video data and outputting it to the rotation processing device S403;

[0084] The rotation processing device S403 is connected to the renderer S404, and is used to rotate the input decoded video data according to the set rotation angle, and output the video image data at a certain angle ...

Abstract

The embodiment of the invention provides a processing method for rotating video in broadcasting, a device and a system thereof. The invention belongs to the field of computer. The processing method comprises the following steps: setting a rotation processor in a filter link broadcasting the video; executing rotation processing to the decoded video data in the broadcasted video through the rotation processor; and outputting the video data which are obtained after rotation processing to a renderer for rendering and then executing output display. The processing method can directly execute rotation processing to the video conveniently through the rotation processor and then outputs the video through the renderer at a state that the video requires rotation. The broadcasting stopping is not required and the user experience is enhanced. Furthermore at the state that the rotation of video is not required, the rotation processor can transmit and output the original input data to the renderer without complicated processing to the data, and therefore the additional resource consumption is not generated.

Description

technical field [0001] The invention relates to the field of computers, in particular to a processing method, device and system for rotating video during playback. Background technique [0002] With the development of computer and network technology, video technology has been widely used. Video rotation is a method of processing the source video so that the video image presented by the video player is at a certain angle to the original video image. Existing video players usually use automatic connection technology to automatically establish the combination relationship of each filter to form a filter link before the video player outputs the video, and only play the necessary filters in the filter link, and automatically The established filter link cannot implement various video post-processing, such as: video rotation, other post-processing, such as color adjustment, subtitle mounting, etc. If you want to achieve various video post-processing, you need to stop playing and re...
