I don't think that there is any guarantee that the 
output is bit-identical but if the input has codec 
x then -vcodec x and -vcodec copy both produce an 
output file with video encoded with x (assuming an 
encoder for x exists and remuxing x is supported).

Please do not top-post here and please consider
