failed to converted raw H264 to mp4 wiht FFMPEG and playback it - ffmpeg

Question

I am trying to convert raw video file captured from Cisco EX60 to valid MP4 file.
I use the following command
ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 1920x1080 -r 25 -i input2 -vcodec libx264 output2.mp4
and get
libpostproc 54. 0.100 / 54. 0.100
[rawvideo # 0000000000703920] Estimating duration from bitrate, this may be inac
curate
Input #0, rawvideo, from 'input2':

When I use just
ffmpeg -f h264 -i input -vcodec copy -r 25 outfile.mp4
It replace initial IFrame with B-frames so I cannot playback it. I can view it with VCL, but not with Windows Media player, for example.
What is wrong with the command?
Thanks

Answer 1

Stream #0:0: Video: h264 (libx264)
This is the source video stream, which is already encoded with h264. So it’s unlikely that rawvideo will work. You actually have to decode the stream in order to encode it again.
As for why you can’t play it back in Windows Media Player, please check the H.264 encoding guide. By default the highest profile is used when encoding as h264 which is not compatible with every device and player. For maximum compatibility, add the following options:
-profile:v baseline -level 3.0
