Systems and methods for group of pictures encoding

Abstract

Systems and methods are provided encoding a video. Video data is captured. The video data is stored in a group of pictures format, where the group of pictures format comprises a plurality of GOP files, each GOP file including exactly one group of pictures unit. The video data is encoded into a prespecified format. Encoding includes accessing the GOP files containing the video data in the group of pictures format, and encoding the video data into the prespecified format using the GOP files to generate an encoded video.

         21 . A computer-implemented method for encoding a video, the method comprising:
 receiving first encoded video data comprised of a first set of GOP units, wherein each GOP unit comprises exactly one independently coded frame and one or more dependently coded frame;   receiving second encoded video data comprised of a second set of GOP units;   receiving instructions for generating third encoded video data based on the first encoded video data and the second encoded video data, wherein the instructions identify a transition portion from the first encoded video data to the second encoded video data; and   generating the third encoded video data by—
 determining a first subset of the first set of GOP units and a first subset of the second set of GOP units corresponding to the transition portion; 
 encoding a transition GOP unit from the first subset of the first set of GOP units and the first subset of the second set of GOP units; and 
 combining a second subset of the first set of GOP units, a second subset of the second set of GOP units, and the transition GOP unit to form the third encoded video data. 
   
     
     
         22 . The method of  claim 21  wherein the first subset of the first set of GOP units comprises one GOP unit. 
     
     
         23 . The method of  claim 21  wherein the first subset of the first set of GOP units comprises a plurality of GOP units. 
     
     
         24 . The method of  claim 21  wherein the encoded transition GOP unit includes at least one frame from the first set of GOP units and at least one frame from the second set of GOP units. 
     
     
         25 . The method of  claim 21  wherein the second subset of the first set of GOP units and the second subset of the second set of GOP units are combined in the generated third encoded video data without re-encoding the GOP units. 
     
     
         26 . The method of  claim 21  wherein the second subset of the first set of GOP units and the second subset of the second set of GOP units correspond to GOP units that do not fall within the transition portion. 
     
     
         27 . The method of  claim 21  wherein the transition portion corresponds to a cross fade, a dissolve, a peel, a hard transition, or a wipe. 
     
     
         28 . A non-transitory computer-readable medium containing instructions configured to cause one or more processors to perform a method for encoding a video, the method comprising:

         32 . The non-transitory computer-readable medium of  claim 28  wherein the second subset of the first set of GOP units and the second subset of the second set of GOP units are combined in the generated third encoded video data without re-encoding the GOP units.

         34 . The non-transitory computer-readable medium of  claim 28  wherein the transition portion corresponds to a cross fade, a dissolve, a peel, a hard transition, or a wipe.
