We can add gstreamer-MediaSDK plugin into gstreamer-1.0, and see 16 elements using command "gst-inspect-1.0 | grep mfx".
16 elements listed below:
ubuntu@LR29b5-DevHost-ApolloLake:~$ gst-inspect-1.0 | grep mfx
mfx: mfxh264dec: MFX H264 decoder
mfx: mfxhevcdec: MFX HEVC decoder
mfx: mfxmpeg2dec: MFX MPEG2 decoder
mfx: mfxwmvdec: MFX WMV decoder
mfx: mfxvc1dec: MFX VC1 decoder
mfx: mfxvp8dec: MFX VP8 decoder
mfx: mfxvp9dec: MFX VP9 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: mfxmpeg2enc: MFX MPEG-2 encoder
mfx: mfxjpegenc: MFX JPEG encoder
Although we're able to build the gstreamer-msdk, but find error in using mfx elements.
For example, with command "gst-launch-1.0 filesrc location=/home/ubuntu/video_files/What-is-XenDesktop_H264_AAC.mp4 ! qtdemux ! h264parse ! mfxh264dec ! fpsdisplaysink video-sink=mfxsink" comes error below:

Does anyone find the same problem? How to fix it? Thanks in advance for the feedback.
