Hi Veeranna, How many instances did you launch? can you remotely access your machine when system hang?
Thanks Haihao Hi, I have downloaded krogoth version of yocto and build it. Kernel version : 4.4 gstreamer-vaapi : 1.8.0 libva : 1.7.0 Intel-driver : 1.7.0 Then flashed the built image on haswell(Intel i5-4590) and launched multiple instances of below pipeline and observed system hang at some point. gst-launch-1.0 videotestsrc is-live=true pattern=22 horizontal-speed=20 ! 'video/x-raw, format=(string)I420, width=(int)864, height=(int)480, framerate=(fraction)10/1' ! vaapiencode_h264 min-qp=20 ! queue ! vaapidecode ! queue ! vaapisink Didn't get any kernel logs or gstreamer error messages when it occurs. I tried below tests but didn't get helped. 1. Tried kernel version 4.8 2. Other versions of gstreamer-vaapi and libva. Looking forward for your suggestions and let me know if you need more information.
