VLC player unable to play this JPEG2000 clip

I created a JPEG 2000 animation via the following ffmpeg command line:

ffmpeg -i superwalk.gif -map 0 -c:v j2k -strict experimental superwalk.avi

The output superwalk.avi plays just fine in Quicktime. VLC opens it and I can scrub around in the frames but the loop does not play.
