How to use the mfx_gst_h264vd decoding H264 (contains the raw data for I420) RTSP stream ??

exsample :
gst-launch-1.0 rtspsrc typefind=true location=rtsp://admin:[email protected]:554/live/main name=IPtsmuxer3 ! queue max-size-bytes=0 max-size-buffers=3 max-size-time=0 ! rtph264depay ! video/x-h264,framerate=30/1 ! avdec_h264 name=ipdec ! videoconvert name=IPIPU qos=true ! video/x-raw, format=BGRx, width=1920, height=1080 ! queue ! ximagesink -v
this is working very well . because avdec_h264 have format of I420 out .
information follow :
avdec_h264:ipdec.GstPad:src: caps = "video/x-raw,\ format=(string)I420,\ width=(int)1920,\ height=(int)1080,\ pixel-aspect-ratio=(fraction)1/1,\ interlace-mode=(string)progressive,\ chroma-site=(string)mpeg2,\ colorimetry=(string)bt709,\ framerate=(fraction)30/1"

but :
gst-launch-1.0 rtspsrc typefind=true location=rtsp://admin:[email protected]:554/live/main name=IPtsmuxer3 ! queue max-size-bytes=0 max-size-buffers=3 max-size-time=0 ! rtph264depay ! video/x-h264,framerate=30/1 ! mfx_gst_h264vd name=ipdec ! mfx_gst_vpp format=8 ! video/x-raw, format=BGRx, width=1920, height=1080 ! queue ! ximagesink this is not working
bacause mfx_gst_h264vd out format is only nv12

Most of MediaSDK decoders (including AVC) support only NV12. In order to convert to BGRx please try something like:
... rtph264depay ! video/x-h264,framerate=30/1 ! mfx_gst_h264vd name=ipdec ! autovideoconvert ! ximagesink
