Dear ALL:
My computer's CPU is intel i7-8700K (12 cores), and also has a Nvidia GPU: GTX 1080 card, and the OS is Ubuntu1604 LTS。
I want to use gstreamer gst to test hardware accelerated decoding using intel integrated GPU and nvidia GTX 1080 simultaneously.
First, I can use nivida deepstream plugin for gst to decode vedio files using gtx1080 successfully.
The command as this:
#gst-launch-1.0 filesrc location=./Clip_1080_5sec_10mbps_h264.mp4 ! qtdemux ! h264parse ! nvdec_h264 ! fakesink
Second , I installed intel media sdk and gstreamer media sdk and vaapi driver from sources.
gst can find the mfx plugins:
#gst-inspect-1.0 | grep mfx
mfx: mfxh264dec: MFX H264 decoder
mfx: mfxhevcdec: MFX HEVC decoder
mfx: mfxmpeg2dec: MFX MPEG2 decoder
mfx: mfxvc1dec: MFX VC1 decoder
mfx: mfxvp8dec: MFX VP8 decoder
mfx: mfxjpegdec: MFX JPEG decoder
mfx: mfxdecode: MFX Video Decoder
mfx: mfxvpp: MFX video postprocessing
mfx: mfxsinkelement: MFX sink
mfx: mfxsink: MFX Sink Bin
mfx: mfxh264enc: MFX H.264 encoder
mfx: mfxhevcenc: MFX H.265 encoder
mfx: mfxjpegenc: MFX JPEG encoder
mfx: mfxvc1parse: VC1 parser
However , when I tested gst using mfxh264dec , I got following error, I googled the error but got no useful info for this.
The command as this:
# gst-launch-1.0 filesrc location=./Clip_1080_5sec_10mbps_h264.mp4 ! qtdemux ! h264parse ! mfxh264dec ! fakesink
Error Output:
# gst-launch-1.0 filesrc location=./Clip_1080_5sec_10mbps_h264.mp4 ! qtdemux ! h264parse ! mfxh264dec ! fakesink

Please help me , what should I do ?
Could it be that BIOS not configured or driver not right or something else?
I found someone said that's opencl render error about x11 because I have two GPUs. I dont know what that mean.
How can i use intel iGPU and nvidia GPU simultaneously?
