4K playback options...

My PC is a small form factor Ivy Bridge i7 @3.1GHz with 16GB ram and an SSD.

I have some 4K files using HEVC that playback okay but occasionally it's not perfect. I know it's all being done with the CPU, but I have to think that the players aren't quite there yet.

VLC is buggy, Media Player Classic works the best. I hear that MediaPortal can work but haven't tried it yet.

Anyone have advice? I can't find much info on when the integrated Intel chipsets and discrete video cards will be supporting HEVC. Anyone know?

I'm connected via display port to a 27" 2560x1440 display - the 4K source is a marked improvement over 1080p upscaled to native.

Intel iGPU supports HEVC decoding, according to Intel 3621 driver release notes:

Quote:
HEVC decode now supported by the driver and video players can now take advantage of the GPU accelerated decode support offered by Intel

However it seems that there is no HEVC decoder yet supporting it. I tried PowerDVD 14, playback of "Elecard 4K video about Tomsk Part 1" with Pentium G3430 was choppy.

Nvidia has added HEVC GPU decoding too at Kepler and Maxwell cards with latest 340 beta drivers, although we don't have info about performance yet because there is no decoder leveraging this kind of acceleration, just like Intel.

Using SW decoding, you could try PotPlayer.

Here's the way I currently play the 4K content I have. I put the files on my NAS (Synology DS1812) server, and have it's DLNA host serve them via a separate folder named "4KVideo". I just keep it separate so I don't mix it all in with the storage of all my other MKV files. I then use my player on my TV (Samsung HU8550) to play off of my NAS.

Plays perfectly (as well as from a USB3 stick plugged into the TV) and never skips a beat. I'm not a huge fan of DNLA, but very effective for this application, and the player on the TV plays it very well, just don't expect to get anything more than 5.1 audio (no lossless). As I have no lossless-audio 5.1+ 4K content, not a very bid deal at this point.

Although I have no full-length movies (yet), this would work just fine for those, as long as I could live without lossless audio. Ultimately, I'll likely configure a worthy 4K HTPC, but I can at least play most of the available 4K content this way for now.

Yeah, but your TV must be new with HEVC support. Ideal, but I'm not ready to take the 4K plunge yet.

Where are you guys getting 4K videos at? The only thing I've come across is a trailer for Gravity. I'd love to play around with it.

Yes, I would also like to know where to get 4K content. Enjoying stuttery 4K YouTube videos is hard on my Asus PB287Q. I only have 2-3 trailers I got from hd-trailers.net

There is a 300gb torrent that's a demo that floats around - it's 12bit. Probably take a month to download though .... Lol

I installed MediaPortal and the 4K playback is superb. FYI if anyone cares...
