Machine and application hang when we stop or start H264 Encoding

Hello,

Earlier we are using Intel Media SDK 2013 and driver of version 10.18.10.3496. With this version of driver, recording/encoding in our  application ( h264 - 1080i50 format and mpeg - 720i50) working OK.

But if we install newer version of driver then our application hang when we start or stop recording/encoding. Sometime encoding not started after we start and stop encoding for 10-15 times.

Also After updating Media  SDK to 2014 R2 Client  and updating driver to ver 10.18.14.4264, then also I am facing same problem.

I attach my system log.

Regards
