Something

if I mux a video like this, it does not work:
gst-launch-0.10 filesrc location=XMen3Trailer.yuv blocksize=109824 ! video/x-raw-yuv,format='(fourcc)'I420,width=352,height=208,framerate='(fraction)'15/1 ! hantro4200enc stream-type="0" ! queue ! avimux name=m ! filesink location=XMen3Trailer_s0.avi filesrc location=XMen3Trailer.mp3 ! audio/mpeg,mpegversion=1,layer=3 ! queue ! m.

But if I ommit the queue for the video-part it muxes:

gst-launch-0.10 filesrc location=XMen3Trailer.yuv blocksize=109824 ! video/x-raw-yuv,format='(fourcc)'I420,width=352,height=208,framerate='(fraction)'15/1 ! hantro4200enc stream-type="0" ! avimux name=m ! filesink location=XMen3Trailer_s0.avi filesrc location=XMen3Trailer.mp3 ! audio/mpeg,mpegversion=1,layer=3 ! queue ! m.
