Video playback problem with omx

[Abin P]

Hi all
I build  a kernal on Rcar E2(arm based board).I already installed  weston
/wayland ,gststreamer-1.0 with omx(hardware acceleration enabled) in R
car-E2. I checked all the omx plugins installed in Rcar E2 using
gst-inspect-1.0 omx .

Omxh264enc:openmax h.264 video decoder

Omxwmadec: openmax wma audio decoder

Omxmp3dec: openmax mp3 audio decoder

Omxaacdec: openmax aac audio decoder

Omxh265dec : openmax h.265 video decoder

Omxvc1dec : openmax wmv video decoder

Omxaaclcdec: openmax aac audio decoder

Omxmpeg4videodec : openmax mpeg4  video decoder

Omxh264dec : openmax h.264 video decoder

Then i tried to test omx hardware acceleration  using pipeline
gst-launch-1.0 -v  filesrc location=sample.mp4 ! qtdemux name=dmx
dmx.video_0 ! h264parse ! omxh264dec ! waylandsink

Also checked

gst-launch-1.0 -v  filesrc location=sample.mp4 ! qtdemux name=dmx
dmx.video_0 ! video/x-h264 ,width=1280,height=720,framerate=25/1  !
omxh264dec ! waylandsink

But i got plenty of errors.no video shown in display.I attached the error
summary using debug
GST_DEBUG =4 gst-launch-1.0 -v  filesrc location=sample.mp4 ! qtdemux
name=dmx dmx.video_0 ! h264parse ! omxh264dec ! waylandsink

Is there any issue in my pipeline?
Can anyone help me to find the real root cause of this error.

Thanks & regards
Abin
