Hmm, I got the following resulst:
root at beaglebone:~# gst-launch-0.10 filesrc location=cinedemo.m2v ! mpegvideoparse ! ffdec_mpeg2video ! ffmpegcolorspace ! fbdevsink device=/dev/fb0 -v
WARNING: erroneous pipeline: no element "mpegvideoparse"

It seems that the plugins such as "mpegvideoparse" and "fbdevsink" are not
enabled for BBB BSP. Have you made any change to gstreamer recipe?

Thanks,
Kevin
