A normalization is performed by the software. ; if type is "angleAxis" you have to give an "angle" in degree and a direction vector x, y, z that generates the rotation axis (this vector should not be (0, 0, 0)). rotation= {"type":"euler", "yaw":0.0, "pitch":0.0, "roll":0.0} ;rotation= {"type":"quaternion", "w":1.0, "x":0.0, "y":0.0, "z":0.0} ;rotation= {"type":"angleAxis", "angle":90, "x":0, "y":0, "z":1} ;nbHTiles (resp. nbVTiles) indicate the number of horizontal (resp. vertical) tiles ;You have to compile the software with the RANGE_NB_H_TILES and RANGE_NB_V_TILES macro to be able to use this layout. ;For instance in this example the value 8 should be in the macro RANGE_NB_H_TILES and RANGE_NB_V_TILES otherwise a runtime error will be raised nbHTiles=8 nbVTiles=4 ;hTileRation_X and vTileRation_X indicate the relative horizontal and vertical ratio of the tile X. In this example each tile get 1/8 of the equirectangular picture hTileRation_0=1 hTileRation_1=1 hTileRation_2=1 hTileRation_3=1 hTileRation_4=1 hTileRation_5=1 hTileRation_6=1 hTileRation_7=1 vTileRation_0=1 vTileRation_1=1 vTileRation_2=1 vTileRation_3=1 vTileRation_4=1 vTileRation_5=1 vTileRation_6=1 vTileRation_7=1 ;if upscale is set to true, all the tiles will be upscaled to the original tile resolution upscale=true ;if useTile is set to true, each face will be encoded into an independent video with a target bitrate set by the equirectangularTileBitrate_0_0, equirectangularTileBitrate_0_1, etc. parameters ;if useTile is set to false, the whole projection will be encoded into a unique video (all faces on the same frame) and a global bitrate target set by the bitrate parameter useTile=false ;resolution of the tile (i,j)=(0,0) equirectangularTile_0_0=1 ; bitrate of the tile (i,j) = (0,0).

A ratio r means a bitrate of rvideoOutputBitRate bitrate=1`
The bit rate of the resulting video is 3903kb/s. https://user-images.githubusercontent.com/64078936/119605246-03187780-be23-11eb-9f36-2a9e379a303e.mp4
It is easy to get that 3945 is greater than 3903, so why is the bit rate of the video with some high-quality areas and some low-quality areas higher than that of the original input video?
Could you help me solve my doubt？
