How would that work? (in theory) Either you did set an (average) bitrate when starting the encoder, then you know which value you chose and if you also know the length of the input, you can calculate the size of the output file. FFmpeg generally cannot know the length of the input. If you did not set a bitrate (but constant quality) then it is impossible to calculate the output file size.
