As Zhili Zhao said, the problem is the user is using hls_time with too
short duration and want split not by keyframe.
I have been think about how to make the user know it don't support
short than 2 frames and with bframes,
but this is not the better way.
I think give a suggestion and warning message is better.
Feel free comment better ways.


Thanks
