HEVC Playing Performance

Post by Saad on Fri Jul 18, 2014 8:59 pm

Hi,
Some videos of new codec HEVC, use much hardware and don't play smooth. like this:
http://trailers.divx.com/hevc/TearsOfSteelFull12min_1080p_24fps_27qp_1474kbps_GPSNR_42.29_HM11.mkv

but in new version of DivX Plus player, v 10.2.2 , for same video use little CPU and video playing is smooth and performance is nice.

does new k-lite hevc codec do like divx?

The HEVC decoder is still in heavy development. You can expect performance improvements in upcoming versions.

This sample plays smoothly on my computer.

I have some samples too, but not all run smooth.
My PC: Pentium D@2.8Ghz, 4GB ddr2, Nvidia GT 610

1. sample from earlier this year.

Format/Info                              : High Efficiency Video Coding
Codec ID                                 : V_MPEGH/ISO/HEVC
Width                                    : 1 920 pixels
Height                                   : 1 072 pixels
Display aspect ratio                     : 16:9
Frame rate mode                          : Constant
Frame rate                               : 23.976 fps
Overall bit rate                         : 2 534 Kbps

2. sample encoded in summer.

Format/Info                              : High Efficiency Video Coding
Codec ID                                 : V_MPEGH/ISO/HEVC
Bit rate                                 : 2 377 Kbps
Width                                    : 1 920 pixels
Height                                   : 1 072 pixels
Display aspect ratio                     : 16:9
Frame rate mode                          : Constant
Frame rate                               : 23.976 fps
Bits/(Pixel*Frame)                       : 0.048

The settings used during encoding can have an effect on the decoding complexity.

Be sure to use the x64 version of MPC-HC, because that has much better performance for HEVC.

Good to see it, i was always using MPC 32bit to run all videos, and now i see than x64 decrease by half the % of CPU usage to run HEVC videos.

Yes, on average the x64 version is currently about twice as fast for HEVC. The HEVC format is still very new and encoders and decoders will continue to improve over the coming months and years.

For mainstream formats like H.264 the performance difference is relatively small, less than 10%.

I tried to play 4K .ts, that I've got from Eutelsat W4 36E (12169 R/V, DVB-S2/8PSK, 27500, 3/4), but with rather bad result on my 3 GHz i7-860. Any ideas? My record is here https://yadi.sk/d/0xTpShDOcGZVK
Thanks in advance.

That file contains 10-bit video, which is more difficult to decode than normal 8-bit video. Your CPU is not fast enough for this file. I have a faster CPU and I am barely able to play it.

IMHO there is an other reason. On second thoughts I discovered that my recorded stream is not correct classic TS, because the source isn't MPEG-2 TS (ISO/IEC 13818) but it is MPEG-H/HD (ISO/IEC 23008). You can make sure of it if you receive and record the said stream. My hardware with MPC-HC provides the smooth playing of both H.264 and H.265 video files with bitrate about 60 Mbps but not this file. Thank you for your attention.

The container format has no significant effect on performance.

This file is hard to decode because it is 10-bit and it is also 50 fps. Movies are just 24 or 30 fps.
