[FFmpeg-user] ffmpeg crashes with -force_key_frames?

[Wan-Yi Lin]

Hi, ffmpeg:

I am very new to ffmpeg so if my question is silly, please forgive me.
Thanks in advance.


My goal is to encode the video so that there is an I (key) frame at 10
second mark(or right after 10 second mark). I tried

ffmpeg -i  input.avi -acodec ac3 -vcodec libx264 -b 1200k
-force_key_frames:v 00:00:10:00 out.avi

but ffmpeg crashed. I tried on Windows and Linux, both ffmpeg crashed.


Did any one encounter the same problem?  Anything wrong with my command?

Thanks in advance,


Wan-Yi
