Hi,

i created a transcoder configuration on my main /live/ application, i’m trying to transcode a 720p signal into:

240p @300kbps

360p @650kbps

576p @1.500kbps

I am using QuickSync as driver on a Ubuntu Server with:

CPU: Intel i7 4770, GPU: Intel HD 4600

I get an error each time i try to start on ONLY one of the streams, at random, the error is:

```auto
INFO server comment - JNI:TranscoderSession.videoEncoderAdd[_defaultVHost_:live/_definst_/live:240p]: Create video encoder: H.264: QuickSync
INFO server comment - JNI:VideoEncoderH264QuickSyncHost.createDone[_defaultVHost_:live/_definst_/live:240p]: Loading shared library: /usr/local/WowzaStreamingEngine/lib-native/linux64/libwms-vencoder-h264-quicksync-drm.so
WARN server comment - JNI:VideoEncoderH264QuickSyncHost[_defaultVHost_:live/_definst_/live:240p]: QuickSync: Init encoder failed [MFX_ERR_DEVICE_FAILED]
WARN server comment - TranscoderWorkerVideoEncoder.setupEncoder[_defaultVHost_:live/_definst_/live:240p]: Error videoEncoderInitialize[H264]: 4293853206

```

the other two streams are working perfectly.

I tried changing config several times but no joy, the weird thing is that if i remove one of the streams i get the error anyways, i even tried only keeping one and it gives the error!

If i try to transcode using two quicksync and one default it works.

Thanks in advance, any help is greatly appreciated
