I'm quite new to gstreamer. I'm trying to play a mpg video file with the gstreamer1.0 playbin element.
When I use the following pipeline everything works fine and the video is shown:
gst-launch-1.0 -vm --gst-debug=3 filesrc location=/opt/aac-files/MPEG2-av-ps-short.mpg ! mpegpsdemux ! multiqueue ! mpegvideoparse ! mpeg2dec ! videoconvert ! videoscale ! video/x-raw,format=BGR16 ! waylandsink surface-id=1000
But when I use the playbin element I get an invalid format error message:
:/# GST_DEBUG=waylandsink:DEBUG,wayland:DEBUG gst-launch-1.0 playbin uri=file:///opt/aac-files/MPEG2-av-ps-short.mpg video-sink=waylandsink surface-id=1000

Is there a possibility to set the correct video format with playbin?
