HEVC decoder plugin blocks AVC decoder

I'm using Intel® Media Server Studio 2015 R4. My application makes usage of the media sdk library (libmfxsw64.dll) for decoding AVC video.

As soon as I add the HEVC decoder plugin folder to my application (15dd936825ad475ea34e35f3f54217a6 plus content), the initialization of AVC decoding fails in MFXVideoDECODE_Init with error MFX_ERR_INVALID_VIDEO_PARAM.

I even do NOT load the plugin with MFXVideoUSER_Load (.. MFX_PLUGINID_HEVCD_SW ..), so I wonder what's the influence of the plugin folder here?

HEVC Decoder Multicore Performance

I'm running Intel® Media Server Studio 2015 R4 and use the HEVC decoder plugin.

As far as I understood, it will work CPU only. So I'd expect near 100% CPU usage, but I see only 50% and running two cores only.

I already tried to adjust mfxVideoParam.AsyncDepth and mfxInfoMFX.NumThread, but this does not make a difference.

Am I missing anything?

Sample Encode


I am trying to use sample_encode to encode raw YCbCr frames captured from a webcam using EmguCV in a C# project. I understand that sample_encode expects a YUV/NV12 file as input in order to encode. Is there any way to modify the sample_encode in order to work with individual frames rather than an entire file, as I would like to be able to compress a live feed.

INDE Media Video Capturing for Unity 5


I have used the "Intel® INDE Media for Mobile Tutorials - Video Capturing for Unity3d" tutorial to succesfully capture video in an Unity 4.6 app for Android, but now that I've upgraded to Unity 5 it records corrupted video. The recorded video just shows a still picture of pixelated colors. I could use some tips on how could I implement this video recording capability in Unity 5. Thanks in advance!
