<br>
After this patch, x265 seems to always produce constant length gop,<br>
where length is max keyint, completely ignoring scene cuts.<br>
<br>
For example, having --keyint 360 will produce a stream where IDR is<br>
inserted at 0, 360, 720, 1080, 1440, 1800, ... all the way to the last<br>
frame.<br>
<br>
I back out the related patches (rev 10912, 10923, 11005) and it's back<br>
to normal.<br>
<br>
Can you reproduce this behavior? Is it a feature or a bug?<br>
<br>
I've also left a post in doom9 thread.<br>
<br>
Thanks<br>
