Was trying to match other video streams that I did not want to reencode which already had a constant key frame interval (from a camcorder). When merging these will the new x264 ones it causing the mp4box muxer to start new streams.</div>

Is there any particular reason why'd you want to enforce a high<br>
keyint_min? x264 is quite good at deciding optimal keyframe placement<br>
by itself.<br>
<br>
The technical answer is that keyint_min is actually restricted to the<br>
interval [1, keyint_max/2+1]. Loren made this change back in 2005 (<br>
<a href="http://git.videolan.org/?p=x264.git;a=commit;h=648328088b1c4bfb3afcbc92b6711cb7b7b5e068">http://git.videolan.org/?p=x264.git;a=commit;h=648328088b1c4bfb3afcbc92b6711cb7b7b5e068</a><br>
), but I don't really know the reason behind the restriction and if<br>
that reason is still relevant today. You'd have to ask him.<br>
