QuickSYnc Media Encode/Decode Acceleration

I have MSS Pro installed on my system. I would like to run VLC using the MSS video accelerator to benchmark some video apps. How do I know if VLC is using the MSS QuickSync accelerator ? If not, how do I configure VLC to use it?

Also, after installing MSS, when I tried to download the driver Intel suggested, I get the message the recommended driver is not the latest one as installed by MSS:

Running on the S1200RPM by MediaServerStudioEssentialsEvaluation2015R3

S1200RPM with the CPU witch type is Xeon E3-1226 installed the MediaServerStudioEssentialsEvaluation2015R3.But,it failed to run the hardware transcode.


MediaServerStudioEssentialsEvaluation2015R3 comes with sample can alos not to run successfully,saying that ailed with unknown libva error,driver_name=(null).

GIGABYTE Z87 with the CPU witch type is i3 get the same configuration ,however,it can run hardware transcode successfully.

Video Conference setup on h264 decoder has huge latency


I am trying to use MSDK HW h264 decoder for video conference usage on win32 platform. I tried to use MFXVideoDECODE::DecodeFrameAsync interface to do the job.

I followed  to config mfxVideoParam::AsyncDepth = 1 and set mfxBitStream::DataFlag = MFX_BITSTREAM_COMPLETE_FRAME each time I feed in a new frame.

OpenCL GPU driver for i5-3450S CPU


We have an Intel Core i5-3450S processor with integrated gpu. I believe it has Intel® HD Graphics 2500  graphics device. We are running CentOS 7.1 OS on it.

I notice that the recent Media Sever Studio only supports HD Graphics series greater than 4200 ( Could you point me to the equivalent Media Server Studio or a working OpenCL driver for the i5-3450 S processor?


Incorrect Video Orientation / Rotation


I have been trying unsuccessfully to encode a video and keep its original orientation. Below is the code I am using with no luck. I have pulled this together from your samples and a few posts from this forum. Any guidance you could provide would be greatly appreciated.

I have also attached a sample video file I have been testing with that was recorded on a Moto X (2nd gen) running Android 5.1 and what the output looks like.

what are the meaning of intel_gpu_top information when encoding by qsv


         I use qsv to encoder 8 video streams ( mpegts udp --> h264 rtmp,  720P), and watch gpu usage by intel_gpu_top.  because we use msdk 1024 in our encoder product, so I can't use metrics_monitor in product. I googled but not found the meaning of intel_gpu_top output.  

          What are the meaning of  intel_gpu_top information: render, bitsteam, GAM, TSG, VFE, TDG?   Thanks very much !


session independence and error_not_supported ..

I'm currently having a problem and wonder if someone could shed a light on how to solve it. According to the docs: "Each SDK session can independently be a software-based session or hardwarebased session." which here unfortunately seems not to be the case. Basically the problems breaks down to an error MFX_ERR_UNSUPPORTED returned by a call to MFXInit (MFX_IMPL_HARDWARE_ANY) function under some special circumstances. These are as follows.

Removing CPU-GPU sync stalls in Galactic Civilizations* 3

Galactic Civilizations* 3 is a turn-based 4X strategy game recently released by Stardock Entertainment. This article describes how Intel® INDE Graphics Performance Analyzer's (GPA) Platform Analyzer was used to improve the game's performance by finding and removing several CPU-GPU sync stalls that had caused a loss of parallelism between the CPU and GPU.

    I`ve downloaded latest version of Samples for Intel Media Client (version but was unable to build it with Media SDK - there`s a change in mfxInitParam structure which this version of MSDK doesn`t know. As I understand there is a new version of MSDK available, but how can I get it? I tried to reinstall Media SDK with INDE installer but received the same version...
