I need to stream a video using gstreamer. After giving media-ctl commands correctly When I give this command LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so mplayer tv:// -tv driver=v4l2:device=/dev/video6 -vo png -fps 1
, it is successfully capturing frames but only problem with Gstreamer.
Gstreamer pipeline:

After changing resolution, I get same error:
