We can actually. Source attribute indicates the reference frame. Due to the nature of encoding it can be the previous one or the next one.
But it can be any of the previous frames or any of the future frames, right? It need not be the adjacent frames.
I want to get the information about reference frame of motion vector, in order to normalize mv. I think, using FFmpeg, we cannot extract reference frame data. Because, there is a comment below in libavutil/motion_vector.h.
I am searching the tool to get fully information of motion vector from compressed videos. Could you give me some advice?
