Hello,
i’m running Wowza Streaming Engine 4.1.2 on ubuntu 14.04LTS, CPU is i7-3770. and i configure quicksync follow this page https://www.wowza.com/docs/how-to-configure-quick-sync-accelerated-encoding-on-linux.
now i have 5 channel transcoded take advantage of quicksync at the same time, the source signal were 4* 1920x1080 + 1*1280x720 with bitrate 12Mbps average, and the CPU or gpu utilization is all around 50%. but i got some error message in the log file as this:

sometime is the audio timecode out of order, and then it may cause black screen or audio miss. anything i can do to deal with it.
by the way, have your ever do the test with 3rd Generation Intel Core cpu, got some Transcoder performance benchmark like this page:https://www.wowza.com/docs/wowza-transcoder-performance-benchmark
Thanks
