Comment (by David Johansen):

 Unfortunately, it appears this issue is in the encoder or something
 further down the line and using `-use_tfdt 0` doesn't resolve the issue.

 Here's an example video that results in 12 keyframes when the input has
 10:
 https://drive.google.com/file/d/1WxOrSi-
 GNB45nLUUiR4PT7c4H2VurtKk/view?usp=sharing

 And this command to generate the output:
 `ffmpeg -use_tfdt 0 -i input.mp4 -c:v libx264 -force_key_frames source
 output.mp4`

 And then this command to see how many keyframes there are:
 `ffprobe -show_entries frame=pict_type,pts_time,pkt_pos -of csv=p=0 -i
 output.mp4 | grep I`
