Well I'm most certainly no expert but I tried your little example.
The line that worked for me ...

ffmpeg -threads 3 -i in.h264 -vcodec mpeg4 -r 25 -sameq outfile.mp4

I didn't need to " -f h264 " but I did need to force the codec
which, running the way you expressed it, complained about the
frame rates being incompatible (and quite rightfully ?? so because MP4
is only 25 fps ???)

FWIW, I tried your lines and it "sort of" worked. The '-f h264' was
needed. There's sound? The quality was crude and the file size
truncated at about 4 Mb but refused to play in Windows Media beyond 8
secs of the file's max duration. Bar "flipping/tilting" =  1 tilt/sec.
In contrast, my working line rendered a bar sway of about 2 tilts/sec.


Perhaps ffprobe -show_streams your_original_infile.xxx ?
