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 ...
