problem playing low resolution videos with gstreamer 1.8.3

[reyhaneh Yazdani]

Hi guys,

I have a problem with gstreamer 1.8.3 on imx6.

Previously I could play video with low resolutions like standard definition
on gstreamer 1.6.3. But now after upgrade gstreamer to the 1.8.3, it is not
possible more, even though I can play HD and Full HD video with it.
The problem is back to good plugin. I kept the version of other plugin in
1.8.3 and just down grade the good plugin into 1.6.3 and the video is
played.

This is my gstreamer command:

gst-launch-1.0 -v \
filesrc location=Embedded_Systems_EN_V4-Mobil.mp4  \
! qtdemux name=demux  \
demux.video_0 \
! queue  \
!  h264parse \
!  video/x-h264,stream-format=byte-stream \
! v4l2video4dec output-io-mode=2 capture-io-mode=4
! v4l2sink device=/dev/video/by-name/voutbg-2  io-mode=5 sync=true \
crop-top=0 crop-height=1080 overlay-height=1080


This is the output:

And this is the result of gst-inspect:

video4linux2:  v4l2video4dec: V4L2 Video Decoder

I would appreciate if someone can help me. I have tried to figure it out
what the problem is, but no success.

Thanks in advance
