The cu-tree code was adapted from x264's mb-tree and x264 supports variable frame rates. x265 doesn't support VFR yet and so you're right we could save some cycles there. At some point in the future we might add VFR support to x265 so you have to weigh possible future work (adding it back) against the compute savings. -- Steve Borho _______________________________________________ x265-devel mailing list [email protected] https://mailman.videolan.org/listinfo/x265-devel
