I want to combine two mp4 videos to form a single mp4 video using ffmpeg.

what i tried so far is 

ffmpeg -i input1.mp4 -i input2.mp4 output.mp4

But, every time i get the video with video codec of first input and not the other. How can i combine them? Any idea on this will be highly appreciated.

As previous answers show, you need to convert first to an intermediate format. If the mp4 contains h264 bitstream, you can use:

ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts input1.ts
ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts input2.ts
ffmpeg -i "concat:input1.ts|input2.ts" -c copy output.mp4

A more detailed answer you can find here.
