![]() I can ensure that they are being used because the "active decoder" shows dxva2cb direct, quicksync or dxva2n in each one of the cases each time that I am playing a clip (using the system try icon). The clips were all recorded when using the Intel Quicksync hardware acceleration but they still produce a sluggish performance. ![]() I've tested Intel Quicksync, DXVA2 (copy-back) and DXVA2 (native) hardware acceleration for the h264 codec in LAV decoder and all of them produce the same result. I have also tried CoreAVC decoder as an external filter and I am getting the same result. I've installed k-lite codec pack MEGA which includes both LAV and FFDSHOW video decoders and I have tested both of them inside MPC-HC and the problem still persists (in both 32 and 64 bit versions of the player). I've used many video players including VLC, MPC-HC, Windows Media Player, Cyberlink Power Dvd and DivX player but all of them are experiencing the same problem when there are moving scenes. I'm running Windows 10 Home 64 bits and all my drivers are up to date (Including the graphic card HD 5500 to version 15. Graphic card: HD 5500 DDR3L SDRAM shared memory Note: the problem occurs in any h264 clip that I have tested, not only on the one I took a video of and it's also far more noticeable and distracting than in the video because I couldn't capture it properly with my phone.ĬPU: i5-5200U 2,20 GHz Dual-core (2 Core) I will now describe my hardware, the software I used (OS, codecs, settings and video players) and technical details of the clips so that you can better diagnose my problem. I have also updated all my drivers including the HD 5500 integrated graphic card. I recently bought this computer and I upgraded the OS to a free copy of Windows 10 64 bits. My CPU is runing under 20% load in all the clips mentioned in the following paragraphs. The clips are from MPC-HC using Intel Quicksync hardware acceleration. I couldn't get a proper recording because I used my phone but it's very noticeable when seeing any movie or clip and very distracting at the same time. Here's a recording of a few sample clips here: The problem is persistent throughout the playback of all my clips or movies encoded in h264. I notice an abrupt transition in moving scenes instead of experiencing what should be a fluent and smooth scene and I do not understand why because my system is powerful enough to do every single task I have put it to do. It's specially noticeable when the camera is panning in a smooth movement because I get distracted by the chunky and jumpy footage or when there are moving objects in the screen and they move suddenly and abruptly across the screen. I have tested clips encoded in low bitrate (3Mbps) and high bitrate (up to 100Mbps) and all of them stutter when being played. In case you need to use the Intel® Quick Sync encoder for video recording, go to Man圜am’s Recordings settings and select the encoder the same way as in RTMP.I'm experiencing some playback problems with h264 encoded clips and I think that it may be related to the drivers of my integrated graphic card.Īll the h264 clips I have tried stutter when playing in various players under default and different settings including enabling hardware acceleration. The option will be grayed out until all requirements are met. Select the Intel Quick Sync encoder option in Man圜am’s RTMP settings Reboot your machine, enter the BIOS and find and enable internal Intel® graphics (iGPU, integrated graphics).īIOS / UEFI settings for internal graphics Update your Intel GPU driverĭownload and install the latest drivers for your graphics adapter from Intel Download Center. Intel® Quick Sync Video feature included in the CPU specifications Enable internal graphics in BIOS / UEFI Intel CPU with Intel GPU and hardware acceleration support,įind your CPU at Intel Product Specifications website and make sure Intel® Quick Sync Video feature is on the list of your CPU specs and marked as “Yes”.This new feature is currently available for RTMP streaming and Video recording only.This guide does not apply to machines with Intel GPU (no external card) or laptops with Nvidia Optimus technology,.This guide will show you how to enable Intel® Quick Sync Video on desktops with external GPU (e.g. Man圜am 6 has widened the range of supported encoding options and now allows utilizing Quick Sync along with the default encoder used in the previous versions. Intel® Quick Sync Video is a technology that allows to offload some tasks such as video decoding and encoding to the GPU and reduce the CPU usage.
