[0016] The following describes in detail a H264 video coding rate control method proposed by the present invention with reference to the accompanying drawings:
[0017] A H264 video coding rate control method specifically includes the following steps:
[0018] A. Determine the target bit of the current encoding frame according to the image complexity factor characterized by the frame difference method; this step includes the following steps:
[0019] A1. Calculate the remaining bits of the uncoded frame according to the following formula:
[0020] T r ( n i , j ) = u ( n i , 1 ) F r X N gop - [ B s 8 - B c ( n i - 1 , N gop ) ] j = 1 T r ( n i , j - 1 ) - A ( n i , j - 1 ) j = 2,3 · · · N ,
[0021] Where T r (n i, j ) Represents the total number of bits remaining when the i-th GO...
