mxf file created by gstreamer unplayable on VLC

Baby Octopus
Hi,

I'm creating sample MXF file using gstreamer through the pipeline

gst-launch-1.0 videotestsrc is-live=1 ! video/x-raw,format=I420 ! x264enc
key-int-max=25 bframes=0 ! mxfmux ! filesink location=/root/out.mxf -e

Unfortunately the generated file is not playable on VLC. I can only see real
running time in the seek bar. Howvever, the content plays fine on ffplay and
gst-launch playbin.

Is this a VLC bug? VLC seems to play other MXF samples that I download from
Web!

Well, it's two against one, so yes, I think this is more likely a VLC
bug. Though, if you find something that isn't correct in the way it's
muxed, which clearly ffplay and Gst have woraround for, then please
come back and we'll try and fix it.

Nicolas
