x265 aka HEVC

this is a new video codec.
it's really good - the normal tv episode that has been encoded to 350mb with h264, now 150mb with x265, and it looks better. wow.

but it's very resource hungry.

my old 2-core desktop can't keep up with it.

question:
is it possible to tweak media player settings to take some load off the cpu's, either by sacrificing image quality or by making better use of hardware accel or both?
fwiw, i have an nvidia geforce gt 610 with nvidia proprietary driver.
i use mostly mpv, but other suggestions are welcome, if it has the desired effect.
my mpv.conf currently looks like this and i admit that the man pages confuse me.

ps:
all other codecs work just fine, even with 1080p

Re: x265 aka HEVC

^ I assume you have vdpau installed and enabled?  Other than that and tweaking the "skip H.264 in-loop deblocking filter" in VLC, I can't think of anything else.  (For what it's worth, I have the same nvidia card on my desktop, but I use the nouveau and mesa drivers.)

EDIT:  Don't know how to tweak this in mpv.

Re: x265 aka HEVC

If I'am reading this https://en.wikipedia.org/wiki/Nvidia_Pu … reVideo_HD right, you would want the latest nvidia card and no idea if/how is that implemented in linux (perhaps vdpau support is enough?). Another option seems to be intel http://techreport.com/news/27677/new-in … de-support .

p.s. mpv has a friendly community on freenode.
