Juddering when viewing 4K video (1 Viewer)

[Neoculture]

So I'm not sure what is going on. For the record I am using MediaPortal 1.22 with MP-TVSeries and MovingPicture.

6+ months ago, I replaced my TV with a 4K screen. I never bothered watching 4K videos because most movies do fine in 1080p - I personally think they should stop adding more pixels and add more frames. But I'm a big Gunnm fan, and when "Alita: Battle Angel" came out I bought the 4K BD version and ripped it as an x265 MKV to my fileserver. I spun up the resolution on my HTPC Windows 7 box to make sure the NVidia card, Amplifier, and TV were happy with the new resolution, waited until MovingPicture had added the movie to its database, and started the playback.

Unwatchable - so much jerkiness and dropped frames, sometimes it gets so bad even the audio cuts out. Damn.

First thought: my wi-fi network isn't fast enough to cope with 4K and everything else which may be going on. Rig a cat6 cable to the HTPC, swap network over from Wi-Fi to Ethernet, fire up the movie again... nope, same problem.

Second thoughts: My (Gb) network really isn't fast enough. Copy the file locally to the HTPC's hard drive and try again using the local file. And a great big nope again.

Out of desperation, I quit out of MP1.22, spin up MediaPlayerClassic... and get flawless playback on the local file in 4K.

So, can anyone tell me what may be causing MP1.22 to choke on this video file when MPC plays it without a problem?

What's the video card?
I'd be looking to see if it supported the H.265 stuff...
Also - LAV filters installed?

Also - LAV filters installed?

Check also that LAV filters are the latest version (0.74.1) there have been problems with both the MP Extension Manager and MP Install downloading an old version see here for further info.

MediaPortal: 1.22
LAV Filters: 0.74.1
Graphics Card: nVidia GeForce GTX 650

Video card does not appear to have any problem when MKV is played though MPC-HC 1.5.3.3856
Also, I have previously watched quite a few x265 TV episodes through MP-TVSeries without a problem

maybe a lav codec settings is not correct. mphc has its own lav built-in, can be found in the MPHC Options menu the Video Codec button to compare if you like ... also a mediainfo of the film would also be very helpful, maybe it's a 10-bit hdr....

Cheers

mphc has its own lav built-in, can be found in the MPHC Options menu

Further to that if you want to compare apples with apples deselect all the MPC-HC internal filters and add Lav audio,video,splitter and splitter source to the external filters then it will be using the same Lav install/setup as MP

Haven't modified MPC yet to retry. I will be able to get to it sometime in the next 36-48 hours. Sorry.
