      Many frames are lost when playing video files encoded @ 50 fps.

      No problem with encoded video @ 25 fps

      Does it fail every single time, or only sometimes?
      If you can offer a % rate please do.

      Always. The video file could be on any external or internal device, the problem is the same.

      How to repro

      Please provide steps to replicate the issue.  These steps are very crucial to finding the root cause and fix.
      A screenshot to illustrate the issue is a huge plus. A video of the failure is even better! Attach to the post or provide the YouTube link.

      1. Just try to read any video files encoded @ 50 fps and you will see. If you don't have any, I can provide some samples.



      2. PS : I can't get Intel SSU to work with Win10 x64 French Version

          Hi JC38,

           

          According to your issue, bear in mind the fps depends on many variables. Video graphics performance, amount of memory (RAM), type and speed of hard drive.

           

          The refresh rates supported by Intel® Iris™ Graphics 6100 are below, using straight video cables (high quality DisplayPort1.2 and HDMI1.4a)

           

          DisplayPort* 1.2 / eDP*U-Processors: 3840 x 2160 @ 60 Hz

          HDMI*: 4096 x 2304, 3840 x 2160 @ 24 Hz / 24bpp

          Please run a third party application called Fraps and perform a benchmark to your NUC. FRAPS game capture video recorder fps viewer

           

          Additional, run our Intel® System Support Utility, it is a new utility, only English version is available yet.

            Hello Mike,

             

            Thank you for this first answer.

            As I wrote in my previous post, unfortunately Intel SSU doesn't run with the Windows 10 x64 french version. I guess this is something linked to the administrator account which is "administrateur" in french. SSU requires administrator rights, and I am administrator group member.

            I gonna perform a benchmark asap with FRAPS.

              Here are the FRAPS results.

              I use 2 versions of the same video. The first used file is encoded at 50 fps 1920x1080 p --> 3 tests done with FRAPS (2 with VLC, 1  with QuickTime player )

              The second one is encoded at 25 fps 1920x1080 p --> 2 tests done with FRAPS (only with VLC)

               

              Frapslog :

              And here is a capture from VLC regarding the statistics when playing the 50 fps file (perdu = lost / missed)

                Here are some informations.

                 

                Now, I can play my videos at 50 fps without losing any frame but I had to do some changes in the application settings.

                 

                VLC : usually with other computers, I never change anything with the default settings. With this one, I have to go Codecs settings and force the hardware decoder settings to DXVA 2.0

                 

                Apple QuickTime : this software is mandatory for installing GoPro Studio, but it doesn't install under Win 10 without a hack. Once QT player installed, even with the Direct X preferences set to enable, it's not possible to view a 50 fps video in a decent way.

                  Hi JC38,

                   

                  Thank you for your feedback. According to your results, it seems to be a compatibility issue between Microsoft® Windows 10 and Quick Time, the operating system has less than 3 months in the market, the issue might be fixed soon.
