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!

Rotation isn't immediate

I'm joining together videos from the front and back camera on Android using Intel INDE Media for Mobile libraries. Each video is recorded from a different camera and may require different rotation angles. When I join the video and watch it, the result is that playback appears to jump before each joined video starts and then rotation occurs about 20-100ms after the next video segment begins. This causes a jarring shift where the video flips cameras and is upside down briefly.
